Hey everyone,
i just chucked a custom 2.5" catback on my GZ20 soarer. . . and im making not much power, and the exhaust added practically no power. .
here is the dyno chart
I am also running 15lbs boost, motor has 95000kms. . .
Also, my ignition reads give between 9k ohms and 13k ohms resistance, is this correct. . .
Basically, what is wrong with my motor, why is it making so little power, and howcome this exhaust hasnt added much?
Is the ECU perhaps retarding timing at the peak torque mark? How do i disable the ECUs ability to do this?
PLLZZZ HELP!

auto's suck, manual will give u alot more power... possibly 30+ hp
exhaust difference looks not bad, plently of extra tourqe in the lower revs, possibly need a 3inch system for better flow at higher RPM's...
u wanna fuck with the ecu u'll have to go piggyback or replace. id say leave it for now though, do a manual conversion

Dunno about auto, but a manual 1g-gte would be doing WAY better than that, especially at 15psi...
Checked for error codes?

No i havent checked for error codes, do i need special equipment??
Otherwise how do i go about doing it?
Surely the auto can't rob 15% from the total output over the manual!!
Man, this is a serious lack of power, even a stock soarer should be making more at the wheels.
i paid 380bux for a brand new catback to find that peak power is unchanged. Will i see better results if i gut the cat???
One more thing, under full boost and anymore than 1/2 throttle the car jerks a lil going up the rev range, is this related?

Make sure car is off. Open the diagnostics connector. Short TE1 to E1. Turn ignition to on. Look at check engine light... it'll flash the codes.

i'd say a press bent 2.5" exhaust isn't gonna cause a 1g to make only 130hp?

|
this is the issue, a cuZt0m cat back will do fuck all to a stock motor, you have to concentrate on the pipe in front of the cat not behind it, not to mention the cat itself
no amount of boost is gonna help if the engine cant breathe

Thanx Hydra, ran codes and got 24, 31 and 34 - which are all related to air intake sensors. Exactly where is this device and is it really the cause of the problem? Btw, does this code mean my AFM is rooted or is there a common fix?
How can i tell if one turbo is jammed without pulling them off? I think it boosts late and one of the turbo compressor housings looks remarkably clean (the back turbo) - actually its totally spotless - no oil at all.
Ill gut the cat today, and try to see whats goin on.
Can anyone else offer any solutions to the problem?

i think you have bigger issues than you might be considering, 130hp for a 1ggte is not even normal, and a catback should of made somewhat of a difference, regardless of whether its a manual or auto.
i agree with whoever said it do your error codes and verify whats going on, thats an article on the web summarising all 11 codes that get flashed out by jumping diag terminals.
well thats just my opinion

behind your filter there should be a lil box this'll have a wire running off somewhere, if your having air flow sensor probs this is where it'll be, replace that and that should make all the dif, is your engine running dirty rich at the moment that is a common sign if your afm or map isn't working properly, as your ecu doesn't know what load the engine is under and compensates with additonal fuel, resulting in black smoke hope this helps

Before you check your error codes, you should disconnect the battery for a while to clear the system. Then go for a quick blat and then check the codes.

if the CAT is old it could be fucked but honestly a decent dump pipe and a new cat would be a good idea

when dynoing your auto 1ggte take overdrive off and put it in manu mode. It will hold the gears longer.
When i dynod mine i got 147.6hp @ rears. stock boost, stock exhaust and K&N filter. however mine is a Gen III motor as i have a supra.

Another thing is that is the Genie Dynojet which usually gives higher readings than Dyno Dynamics, so you could say it is a bit more sick again.

Are you sure you got 34, given thats something which should only happen on a water/air version because it's the overboost. I'm with Cool1. Disconnect your battery for a while, then take it for a drive then check the codes again. Do the simple things like ensuring AFM plug on nice and tight and go from there.

Whilst those leads are probably standard resistance, seriously dude, get some better ones!! the difference better leads makes is incredible.

New leads didn't seem to help me... maybe my stock leads are still ok 
But it doesn't hurt to use new good leads.

What new leads did you use though? Just standard replacement or uprated ones?
And earthing will play a role yes, but I would have thought you'd have other issues with that rather than just some power droppage.

Aight, disconnected battery, dissambled AFM, still got codes 24, 31 and 34. Dont know how a code 34 appears for a GenIII motor though. . .
I think my AFM is faulty, is there anyone in perth i can switch with just to check? The wiring seems fine.
At idle there is a slight burble (sounds like fuel is burning up in the exhaust), and it jerks under power. Im gonna check the AFM, replace the fuel filter, and is there anything else i should do?

I also have drama's with my 1GGTE Running rich as hell. (manual tho)
I ran it on 15psi got 127KW Which was only a tiny improvemnt over stock boost. Problem was, it was runnin super rich! A/F Ratio line on the chart drops vertically down and goes somewhere off the chart when the power starts to come on, and doesn't return untill throttle is relased!
What the hell could make it run this rich?

No, the motor hasnt been puled down (since iv had it), and im yet to check ignition timing, though thats next on my list. What is the standard base timing on the 1G-GTE supposed to be?
Since im on a stock ECU, i cant change the injection settings.
- -Dylo, if ur AFM is all good, it could be ur injectors are leaking (which makes sense coz fuel pressure goes up with boost pressure). Check ur fuel pump and lines. If thats not it, u should get an aftermarket device to adjust ur injection settings.
