 Driven Project Decade...but it ain't all right...
|

Hey guys,
Well, I finally got it into a driveable state and took it for a thrash. Problem being...it's slow. As in, it can barely level peg a stock auto GZ20 Soarer.
For those that have no idea about the car, it is a 1GGTE in a Celica XX (Mk2 Supra), with a 450mm Hybrid clone cooler, 2.5/3" exhaust and Blitz modified CT12's.
First thing I noticed, was that the boost gauge read around the 0.5 bar mark. This seemed a little low, but was consistent, every pass yielded a solid figure.
Other than that, I didn't notice anything in particular. Was hitting full boost by around the 3500rpm mark.
This was the first time in the better part of 2.5 years the engine has been driven properly, until now, it has only been started, or driven under light load conditions. It did get smoother the more I drove it, but not a great deal faster.
I'm going to try and work out what is going on with the codes as soon as I get a chance to find out what is wrong with that, currently the CEL doesn't function correctly.
Any ideas or suggestions would be great. I'd put it down to boost, had it not been for the modifcations and the fact that given it's current state, I've got at least a 200kg weight advantage over the Soarer.
Cheers,
Nathan

Good to hear that you have got it going, but all I can offer is a  and hope that you get it running better.

I couldn't hear anything, and there was rock solid consistency to the amount of boost it made each time.
| rob_RA40 wrote on Fri, 29 April 2005 06:56 |

Could be, but I still would've thought even at 8psi it should annihilate the GZ20.

Timing has been set to 10 degrees with the terminals bridged.

Haha...it's not *that* slow.
As for the question about boost, it's making some boost before then, that's around when it makes max. I'm not sure to be honest where it should be, and remember, it does have high-flowed turbos.
As for smoke, it did have smoke coming from it the first couple of runs, and when it's idling it was running uber rich. It did seem to clear up a little after it'd been actually put under load. I'll check with my mate who was there.
Another thing I didn't think of yesterday, it wouldn't idle any lower than around 8-900rpm with the idle screw all the way in, what do you reckon this could be?

You mean the timing was locked at 10 degrees throughout the rev range?
This is definitely going to hurt it. Your exhaust temperatures would have been up there.

Well if it was sluggish non advancing timing is definitely a symptom. Have a look if your turbos are glowing 
As you say with 8 psi and high flowed turbos it still should romp a GZ20. It is sounding more like timing to me, particularly if it is revving cleanly but slowly.

Well done on getting it going mate - Project Decade will not live up to its name now !
Don't be too concerned with the idle speed screw on the throttle body, my 1G-GZE does exactly that as well, but I will be cleaning the inside of the ISCV soon and that might make things work a little better.
Does sound like it is running uber rich......
Have you checked for any air leaks?
Is your timing advance working ?
Is every sensor plugged in, working OK, and earthed properly ?
Especially those sensors that do not throw a code at the CEL...
I have a similar problem with my GZE and I suspect the main loom earth under the inlet manifold is playing up ?
Is your cat conv OK and exhaust system not blocked ?
Does the cat get orange/red hot after a short drive in the thing ?

Yeah, this could be the problem. Although I pulled it into the workshop and let it idle with the bonnet up before I shut it off, and they didn't appear glowing.

I dunno about that, still got other things to go on it!
My ISCV has been uber cleaned and sealed already, so it works well in idling up the engine, but no love otherwise once it's warm.
I've checked for basic air leaks, the vacuum lines could be the only real source of it, the intercooling piping seems nice and clamped.
All the sensors are definetly plugged in, all the earths as far as I know are connected. I will double check them, especially that one under inlet manifold. I need to get the CEL working too.
How do I check the timing advance is working?
Exhaust is all brand spankers, I'd hope it was okay, didn't check the cat, will get under next time. It sounds f'ing horn though.

No rags in piping, they were all cleaned out and checked with petrol when brought back from exhaust shop.
Checked a few things. Timing is indeed at 10 degrees when pins shorted. Timing advances properly when revved at idle.
Got the CEL working, constantly flashing so that should be no codes correct?
Funnily enough Karl, I did think of that, I double checked last night that throttle cable indeed opens the throttle fully.
All ECU earth pins are indeed earthed. I'm leaning towards a leak of some sort and possibly attributing some of the rest to the fact the engine has been dormant so long...
Any other suggestions?

I'd probably go apeshit on the vac lines, see if you can solve it easily like that. I'm assuming the turbos are perfect (they'd better be, in this amount of time you could have hand milled them from a block of steel and a nail file)

The turbos didn't feel like they had any shaft play when I had the piping off. They are much newer than the engine itself, and the engine has less than 80000km if JMS is to believed.
Could the vacuum lines be causing THAT much of an issue? I mean, I'll go nuts on them next time I'm there, but this is really a heap slower than it should be.

This is true, suppose it's just a matter of eliminating the possible causes, making sure all of those are nice and tight would be a good start.

the main reason I suggest it is I developed a very large split in one of mine, and there was a pretty substantial loss of power. Real slut to find as well

As gold28 just taught me, sensors can degrade over time and give bad/wrong readings to the ECU, that are not out of their limits, but still cause the thing to run rich, and not throw a CEL code.
And yes, continuous flashing does mean no sensor is out of its limits, for those sensors that the CEL reports on.
Given that your vacuum hoses are new and clamped up nicely, I'm starting to think that you have a dicky sensor somewhere, something like the water temp and/or 02, which can cause the rich running.

Could be the sensors, you'd hope not in an engine that's only done 80000km.
The vacuum hoses aren't clamped at all at the moment. The intercooler piping is nice and clamped tight, but all the vacuum lines are just pushed on. This will be the first thing I'll check but it seems really big effects for a small amount of air that could be leaking.
It is running rich, although I wouldn't have thought the O2 sensor in a Toyota engine would be used at WOT at all, which is where the real problem is.

I would like to think the sensors on my 70 000km 1G-GZE are all sweet too, but i think I have poisoned the 02 sensor with a patch of real rich running caused by my effing around with the AFM air bypass screw.
And the wiring near my water temp sensor looks suss, now that I think about it. My 02 sensor was bent in transit when the motor came across to me too....
Anyway....
The path forward is clear Anakin......get those hoses clamped up, and test again....
And its the world's most frustrating situation when you know there is a problem with the engine but the bloody CEL light just keeps on flashing like there is nothing wrong.....

Arrrgh, stupid work. All I want to do atm is try clamping those lines and I'm stuck here! 
Thought just occurred to me, JMS happened to sell my AFM and ECU, and they've replaced them, but is there a possibility they've replaced them with the unmatched ones that may cause this?

Congrats Nathan on getting it on the road.
Looks like I'll have to take on the 'project decade' title now!
Sounds like it would be worth taking it to the dyno just to see what your AFRs are like.

Was thinking about doing that, once I've resolved all the minor possible causes for it being munted, i'll take it somewhere like Hyperdrive around the corner. First thing is those vacuum lines though.
It *did* get smoother as the runs progressed, but there must still be a leak or something, because it's not idling anywhere near as smooth as a Toyota six should.

Good luck for the new job then too mate !
As well as those two numbers you had better give me every other part number you can find on the thing, given as they often have overlapping periods of time, I can use that to usually lock down an almost exact build date. Something like late or early 88 can make a big difference given that production changes occur in Aug/Sept each year.

What's the compression like? If it's had a good thrash now it should be giving repressentative compression results, unlike when it has been sitting around without use.
I have to agree with 82mkII, the dyno is by far the best place to figure these things out if you have a good operator with all the right equipment. Sure it costs money but I reckon enjoying your car is worth a little money.

Dyno is definetly on the cards. Want to try and sort out the simple variables I can rule out before I spend more money.
Going to go out tomorrow and see if I can get some clamps for the vacuum hosing, Supercrap had squat, not even a cap for the ports.
I'm still looking for a picture of my ECU in my archives, but I've confirmed in my EPC that my AFM is the right one.
Compression test will probably be something else I'll do in the near future again. Once again, it's one of those things I'm going to do before I take it to dyno.
Rob raised a good point to me while chatting, there could be an issue with the wastegate actuator on one of the turbos. It has been sitting for a while, it wouldn't surprise me if it has corroded in this time. The only thing that doesn't gel is that it would be weird if a wastegate was stuck open, but it would explain the low boost, the crappy power and the doughy boost response. I'll check it out following the 7M TSRM troubleshooting, and make sure the actuator rods are lubricated and can move freely.

This car is doing my f'ing head in. It's getting closer to the time when I take it to a dyno.
Today I took the lines off the wastegate actuators. I gave the actuator arms a quick squirt with RP7 and then used the air compressor to pulse the arms. The front turbo actuator I can see moving no problems. The rear one I can hear working, but can't see it. It sounds exactly the same as the front one, so I assumed it's working properly.
I bought new clamps for all the vacuum lines, and I bought new hosing for the wastegate to compressor lines. Everything is on nice and tight.
Started her up, warmed it up, then took it for a little drive before nailing it. Boost level hadn't changed, if anything it's going backwards. It feels like it starts to boost, then bam, power goes backwards. I've got the water temp sensor now to check it's reading correctly.
Tomorrow I'll take out the plugs, give em a clean and gap them to 0.8mm.
I had to repair one of the knock sensor plugs on the engine loom when I got it. Definetly could be something to look at. It seems though as soon as it starts to want to make power the ignition is being majorly retarded.
It seems as soon as the list gets smaller, I think of something else  Ah well, it's a good intro to the workings of engines

JCMF,
I suspect my water temp sensor as well and I will test it today.
You *should* not be able to inadvertantly swap the THW and CSI sensor plugs because they should be unique to each sensor, but, I am ready to be corrected !

Mitch.

Hm, if it was a MAP sensored engine i would say that the MAP sensor is the wrong one for the engine. Same thing happened to me when i accidentally put my GE map sensor on the GZE.
Since its not i would look at athe AFM. That and get a timing light hooked up to the car and see if you can get a little bit of boost at idle and check if the timing retards hugely.

I'm not sure, but those two temp sensors are different colour, but the same plug design. They at least look similar! Mine are filthy so I would not be at all surprised if they are giving out faulty signals.

Oh yeh, just to voice my opinion on here instead of just msn, knock sensors?

Knock sensor is a definite possibility. Something to check when it goes to a dyno.
The water temp sensors are the same plug, just different colours. I'm pretty damn sure they were around the right way, but I'm not ruling out anything at this stage. I'm going to go to the car this morning and test the other sensor, this one I have here is within limits.
bbaacchhyy, my charge light has issues to, thats something for me to look at later I can't be bothered atm, and I know the alternator is working properly

JCMF,
Just question, as I think my THW is stuffed as well......
How are you testing the water temp sensor to ensure it is within its limits ?
Pot of water being heated up on the stove with a suspended thermometer (off the bottom) and checking its resistance with an MM as the temperature rises ?
In situ on the car with a thermometer stuck inside the radiator cap, while the car warms up at idling revs ?
Maybe this is stupid but I think it could be false to test one at static/ambient temps when it rarely sees these conditions in the car (only at start-up really) ......
Does this make any sense ?
Thanks,
Mitch.

Don't forget digital dashes have a charge light were anal dashes have a charge guage...

He is right (that is one smart cookie that CrUZida  , so I guess it doesn't really matter then ?
I would still like to understand why it doesn't work though 
Just hook up a positive lead from the battery or alternator ?
Cheers

Not sure exactly hey.
But heres an interesting story.
Mate Kev had Aus delivered 5me+digital. Dropped an import 5mge in there (analdash), and the digital dash charge light became an 'everything is ok' light. In other words, it was on all the time.
His alternator packed it in, and I sold him the alternator from the same car you got that dash from.
From then on the digital dash operated normally.
Go figure

I tested the sensor by first running it in ice water, and checked that it was down towards the 0-10 degree range on the chart resistance wise. Then I got boiling water and tried it straight away and got a resistance reading equivalent to around the 90-100 degree mark, making me think that it was not the problem.
There is now an oil leak coming from somewhere towards the rear as well, and I can only assume it's the rear main seal. Yay! It just keeps getting better with this f'ing piece of shit.
Spark plugs show signs of running rich, although I haven't regapped them yet.
Do you guys have any idea how I could check the knock sensors are working correctly? I'm not entirely sure if it's the knock sensor itself, or the wiring which I had to repair because it was broken.

Just curious, could the air intake temperature sensor possibly cause it? I'm just trying to try all the things I can think of, it just seems feasible that if the engine sees load and it thinks the intake air is massively hot it may retard the timing a shitload.

Yeah air temp sensor is another possibility.
Either retarding timing or pumping excess fuel in, im not sure how the Toyota management works.

Andrew/Baachy - actually the analogue dashes do have a charge light (and a voltmeter).
That charge light behaviour you saw is expected.
Some early MA61s (eg Kev's import & mine) have a charge lamp relay in the body wiring (driver's kick panel). The relay actually inverts the function of the charge lamp output from the alternator. Presumably the digi dash doesn't need the inversion.
When my alternator packed up I discovered that mine is actually the same as a MX62 cressida alternator, not the same as the locally delivered MA61s.
JCMF - sorry for the hijack.
Did your temp sensor curve look anything like the result I got (uploaded lastnight)?
My 1J is throwing a knock sensor code - so I need to look at why as well.
Regards
Peter

Air temp sensor is the next thing I'm going to check.
Peter, I didn't end up checking the gauge sender. I checked that the ECU temp sensor worked towards it's extremities where I could roughly work out the temperature, but I didn't have a thermometer that could read the full scale. I still haven't 100% ruled out what is happening in between these ranges, but I can't see it being too far off it's right at each end.
I'm going to borrow a fuel pressure gauge ASAP and try to rule out the fuel pump.

Is there any way I can check the knock sensor circuit is working correctly?

Run a tank full of low octane fuel ?
Disconnect the things and go for a drive and see if error codes are thrown ?
Does it have a resistence measure to check ?

It has about half a tank of fresh Ultimate 98.
I disconnected the water temp sensor, and it threw code 22.
I don't get your third question.
