OMFG wrong ecu?
|
Thu, 05 May 2005 05:55

hey hey.
just got my car back from wayne park and they tell me the dood who did the engine conversion on my celsior was a total dipshit. 
The guy has wired the 2jz-gte engine to a 2jz-ge ecu and then when he was having problems, tried to band-aid it with greddy e-manage and apexi gear. 
This is why the car is so slow. The 2nd turbo doesnt exist according to the ecu so its not opening the valve... 
Also the bastard doesnt have an air flow meter on it so the car is running rich as fudge (apparently almost went off the scale).
so now i was wondering how hard would it be for me to switch the ecu's over? I need an ecu for a 2jzgte auto, and an engine harness, as well as an air flow meter..
I can get by with my knowledge on engines, but i certainly aint no expert. I would like to get the pro's to do it, but if its too easy, i will definitely have a go.
The car is in brissie so if anyone knows of someone GOOD who can do it for cheaper than normal i would appreciate that info.
Im far more prepared to spend the money than take it to an el cheapo guy, so i would only like to know about good mech's.
Any suggestions would be appreciated 
Thanks
-Aaron

Holy crap. This is precisely why I don't take my car to a workshop for this sort of work... you can never be sure how badly they're going to screw it up. In this case, pretty fucking badly!
Anyway, switching to the proper ECU will be easy IF your wiring loom hasn't been butchered, but from memory the GE and GTE connector plugs are pretty different so it's probably been hacked to the shithouse by the arseclown who did it. 
If you want to compare what you have to my Aristo wiring (with correct ECU installed), that can be arranged.

Maybe the whole 2jzge harness has been used?
Maybe look into sourcing a 2jzgte harness, and going aftermarket ecu.
btw, the 2jzge uses a MAP sensor, not an AFM.

2jzgte = coil pack, 2jzge = dizzy.
How the fuck can you run a set of coil packs of a dizzy equiped ecu?
Stick your head under the dash and see if it is a 2JZGE ecu.
And you might wanna change your sig... "Its SO DAMN FAST"

well like i said, i aint no expert.
wayne park say there was no monitoring of air flow, and that the 2jzgte standard ecu would be more than fine to run it. (also im quite poor so standard = good value)
im not looking to do anything overly special with it, i just want it to work properly
ps it is fast when compared to my 89 integra

Does the fuel pump run constantly with the key on "ON" and the motor off?
Or does it turn off after a few secs?
No monitoring of airflow = no fuel pump = no runny, unless thats been wired dodgy too.
I'd also doubt the motor would be very drivable with no airflow metering.

fuel pump does turn off after engine off..
apparently the engine is just pushing as much fuel in as it can get.

I'm still so not convinced its running on a 2jzge ecu.
Stick your head under the dash/glovebox and see whats written on the ecu.
Bodgied up 2jzgte ecu in limp home mode, yes.
2jzge ecu, not a chance.

Here's what my Aristo ECU looks like. Note it is clearly labelled "2JZ-GT". As above, have a look at yours and see what's written on it. It should be located in the passenger side footwell.

That wiring is a work of art Jeremy 
Something ain't right, GTE = ignitor, GE = Electronic Dizzy.
So they're either running a converter (if somthing even exists) or somebody doesn't know their stuff and has mis-informed you.
You should be letting somebody who's had experience with JZ wiring take a squiz at it (Norbie has already offered) and go from there.

I'm a little skeptical. Check the ECU. I suppose you could make a 2JZGTE run using a GE ECU but it would be very unhealthy.
I also trained at the Norbie School of Automotive Wiring. The Maccas is there for when he's hungry later on.

Thats not the beginning, thats how he drives around all the time.
Its a qlder security system... nobody is going to try to flog a car thats got wiring loom all over the place!
Even if it is a 2JZGTE!

tape is your friend
i have thoughts that you COULD run the 2jzgte off the 2jzge ECU, but it would more than likely be running in base timing mode, and then hence the use of the emanage to play around with ignition timing...
myself i think this is horrid. I thought i was being dodgy running a stock 4age with a turbo on a gze ecu + emanage!!
I hope you get it all sorted. There are a few people, such as wee-man here, who are helpful enough and kind enough to lend a hand and some pointers if need be. Post some pics of the ECU wiring if you can - i wanna see what abortion has been made

i was told the ecu controls a valve between the 2?
anyways i checked it out, ill have to go back on monday or something because ecu is (not so clearly) marked as 2jz-gte.
wtf?
this is really starting to shit me.

just to throw in another variable for all to think about, its got an apexi rev/speed meter (ugly prick of a thing) wired directly to the ecu. Upon removing this i tried starting the car and she did fine, nothing unusual. Revved fine too. Then i took it up the street to test it, and she wouldnt change out of 1st gear.
Someone has done some extra dodgy wiring in this car i thinks.

sounds like the speed sensor was going through the RSM and then to the ECU. When I had no speedo drive in the gearbox the car didn't change out of 1st gear at all.
I would have thought it should be spliced so that the it goes to both places but if one is disconnected the other still gets its signal.

a workmate (who can be VERY full of it at times) has questioned the purchase of a standard ecu. He seems to think that a 2nd hand aft/market one will be only a little more expensive but will be much better. of all areas in automobilia this is the one i know least about, and it just happens to be the one im having probs with 
anyways if i do end up having to buy a new ecu, what do you guys think? will the aft/market one be much better? im not planning to have a race car or anything, but im sure id have fun screwing around with it if i could change a fw things.
if aft/mark is the shizzle, what brands should i look out for (keeping in mind im a student and have little available cash for splashing - but for the right stuff i will always splurge)
thanks

go standard unless - you'll get better fuel economy, it'll plug straight in, and it'll handle 250+rwkw easily (just dont do sticking on giant honking turbos without a clip-on or standalone ecu)

Find out what is wrong before you do anything.
Take it to a few more places, pay a few ppl to have a look.

what he said. it would really suck to fork out for a new ecu and find out that it was just a sensor that was fuggered, or the loom itself was just shoddily put together (altogether possible by the sound of things)

rest assured, im not fantastic wit dis area, but not retarded either
im taking it back to wayne park in the next 2 days so the guy can explain to me why the ecu (which is supposedly a 2jzge) has a 2jzgte label on it. And why i paid him to tell me something which is seeming further from the truth every minute.
i wont buy anything unless there is an overwhelming argument with supporting evidence that the problem is as im told. i was just asking hypothetically.

Sounds like you are going down the right path.
Keep on this track, its a good one.
Also ask him why he thinks there is no air metering, if he says because there is no AirFlow Meter, as him if he knows what a MAP sensor is.

American 2JZGTE's use a MAF from memory, but all Japanese models don't use an AFM, just MAP. I think the dude is going loco.

Take the car elsewhere.
If someone doesn't have the capacity to understand the most basic of engine functions (ie AFM/MAP/MAF) then they most certainly shouldn't be tuning it.
Thats my view of the subject anyway.
Some one who can tune, should also be able to wire up an ecu.

You're missing the point. The car isn't supposed to have an AFM, and he reckons every one he's seen has had one. By extrapolation, he doesn't know shit, and I'd be taking it somewhere else.

Thank you for stating the obvious. Toyota just don't write the E on their ECU's. Seriously dude, you have the correct ECU. If it plugs into the loom it should be right.
Take it to someone who knows what they are talking about to sort it out.

yes there is an internal different between the AUTO and MANUAL ecu's..... the auto ecu will usually have a few wires/signals that go between the ECU and the AUTO computer to control the gearshifts in the gearbox.
When you unplugged your speed limiter thingy, this removed the signals between the ecu and auto computer, such that the gearbox was not being told to shift gears, and was thus stuck in 1st.
YOu have the correct ECU already. Stick with it, get it checked out by someone in the know with Toyota engines and ECUs - enthusiasts with skills and experience are often better than workshops with poo dribbling from their mouths. I would NOT take the car anywhere near this bloke who rekons there is supposed to be an air flow meter on the engine. He is clearly insane, retarded, and has more shit coming out of his mouth than comprehendable sentences.
Check your ECu again to see if it also says the following:
"A/T" or "M/T" - these stand for automatic and manual transmission respectively.
If you have an ECU which also has "A/T" plastered on it somewhere, then there is NO REASON someone cant fix up the wiring, and get that emanage working properly. I rekon this douche has gone and FUBAR-ed your wiring and tried to blame the japs.....
If you are really keen, bring the car to sydney, or wait until Queens birthday long weekend when i am in brisbane for All Toyota Day... i will gladly help out then for a nominal beer/food charge depending on how much FUBAR wiring there is. I'll make Norbie help too
