Did you ever get this worked out? I would love to know your final numbers

Did you get this worked out? I would love to see the finalized numbers for the LS7 using Ls9 injectors

I have been digging through hundreds of posts (many from 2012 and older) concerning the use of LS9 injectors in an LS7. Does anyone have a set of the properly adjusted data for an early 07 Z06 for...

Has anyone gone from a 90mm throttlebody to the new NW103? I have heard mixed reviews of the 102 but I have heard little to none on the 103. Is the tuning similiar? I have a max effort LS7 build and...

Any idea why it appears only stock tune files are now available in the repository? What happened???!!!

I am doing a auto conversion on a 2004 GTO for a customer with a medical issue. He is unable to use the car any longer as a manual and would like an auto car. What will I need to do for the...

I am having almost the EXACT issue in a Camaro Restomod Swap currently... Car will drive normal until 35% throttle at PE. Car shudders and shakes. My 02's tank to less than 50mv. Did you ever get to...

See if he has or is willing to send you another ecu...

For some reason and this has happened on several gto's I tried a crank relearn on.. the e-brake must be active and car in neutral. This car would NOT take a relearn after several attempts as the...

I'm guessing you disconnected the maf, not the map sensor correct?

Trust me, no hard feelings here. we are all trying to get this repaired. Thanks for all your help and advice thus far! I did try the tcs patch and the car stumbles with a load running on the street...

It also has these areas of very low map in coordination with the tanking O2 voltage. I am not convinced it is shutting the throttle. It does accelerate just VERY slowly and rumbles and shakes while...

Unfortunately I do not have the car at my shop to be able to upload and download or log tune data. Unfortunately this project has spun to a much larger issue that I would have to commit substantial...

Adjusted fueling today.. now within 1-2%... Turned on transient fueling as the stock GTO has ON. NO CHANGE NOTED.
In the log file attached shows the O2 sensor voltage tanking at several times. It...

Compared to another stock GTO file only the traction control, several dtc codes and transient fuel were switched off. The rest seemed to match up. I would really tend to doubt the transient fuel...

I also thought about the ECU original calibration issue.... I did look at the 2006 GTO log from another car I tuned and the reversion settings on that car were also backwards...

It stumbles and shakes and hesitates through the RPM range with any load on it... Car does it even at idle with a hard blip of the throttle.

I never noticed that the transient fuel was shut off...

Thank you sir. I appreciate that.

Engine is stock, cam is stock, pushrods stock... Intake pipe and exhaust only.
MAF scalar is a bit out but its not far off enough to cause a stumble SO bad that it wont rev over 3500.

If it was a tuning issue it would be happening ALL the time. I coordinated with 2 other major LS building shops and both have looked at the logs and agree that the issue is well beyond the tune.

As I am on blast in a public forum, I am here to defend myself....

As I am trying to get this fixed I will post the log of the nearly stock base file to help the customer get this fixed and get...

I am installing a set of Lucas Delphi 37# injectors in my 2004 GTO. Car has worked over LS6 heads, cam, fast intake and throttlebody. Looking to see if anyone could assist me in setting up the...

Thanks Huggins.. I most definitely concur. And yes I plan on modifying the MAF curve but with the car misfiring so badly it's on to diagnostic mode, not tuning mode.

Schpenxel- I'm asking because...

Oh and unclipping the maf or shutting it off in the tune and running SD or MAF did nothing to resolve the issue.

Ok...SO... Let me explain...
Car is VERY STOCK... I mean like fresh out of a GTO with the airbox stock.
The PE is still set at the factory 2006 GTO settings...

The only mods are..

Smooth...
