1999 camaro, LS3 swap and trouble with pcm files...help needed

[wmpeekm]

Hi
We have make engine swap from LS1 to LS3 to 1999 Chevrolet Camaro. We use throttle cable, not electric.. we use orginal PCM and need is for new bin och cal file.
LS3 engine is LS376/480 from GM performance parts.
Transmission is auto
mass airflow sensor 15865791
Rear End Gear Ratio: 3,55
Current Tire Size: 275x40x18
PCM is orginal with tune file and we use orginal car wiring harness
Car will start, but it runs really badly. If i press the gas pedal, it kills engine

Here is my bin file...what could be wrong here?

So you're using your LS1 PCM, right...?

Did you swap out the LS3's 58x/4x reluctors for the LS1 24x/1x reluctors...?
If so, did you correctly repin the cam sensor extension harness, and are you using the correct 24x crank sensor...?
If not, are you using the LPE converter...?

Are you running a manifold-referenced FPR or an un-referenced FPR (and did you measure rail pressure)(and did you edit IFR table accordingly)...?

LS376 has bigger injectors, did you edit the IFR table, and the other injector tables also...?
Did you copy various tables from the LS376 E67 tune file to your LS1 file...?

LS376 has a moderately hot cam (480 HP), did you account for this in the VE tables (Primary, Secondary, Cranking)...?

Are you running with MAF...?
If so, you may need to correct it (or verify that it is correct).
If not, do you see an immediate MAF DTC, if you don't then the PCM will be using some calculated MAF value (which won't be close).

Did you log any pids when you ran it...?

Do do get any DTC's...?

Your attached bin file is in HPT format...

Hi Joe

Good list, i need check that i have everything right.
Yes we use LINGENFELTER TRG-002 58X-24X CRANK SENSOR TRIGGER CONVERSION MODULE
yes, i edit the IFR table, and the other injector tables.
Yes running with MAF

I run car with scanner this week, so maybe i know better what goes wrong
Thanks

Did you do this:

Hello did you ever get your ls3 conversion running right? I just did the same on my 2002 trans am and it seems I have know power over 3k car bogs badly... Can you tell me what you did to fix your isse

[bigdawg6114]

Yes for the IFR have not really had a chance to get maf correct and ve, but even with it not perfect it should still spend the tires, right

[bigdawg6114]

I have the same setup as the 1999 camaro so I did look at his tune just to get a baseline

[joecar]

Sounds like you're overfueling, possibly from IFR table being too low...

are you running a manifold-referenced FPR or an un-referenced FPR...?

did you measure rail pressure (with reference removed)...?

Post your tune file, and any logs you have.

[bigdawg6114]

ok here yougo

[bigdawg6114]

I did check fuel pressure and it is 58psi

Commanded AFR is ending up way too rich for a N/A car. You are hitting either cat or piston protection mode which is commanding 11.7:1.

[bigdawg6114]

How can I stop it from going into this mode

B0701 Cat protection, B3652-B3656 piston protection.
