Well, I received this 1967 GTO with what was supposed to be a built 5.3 ls, headers cam and I have no info from the customer as he bought the car as is and the engine builder/tuner will not respond to any of his requests.
I'll post the as-received tune and data logs here.
it is really crazy that this car even ran, it's on the dyno now and it's short and long terms at up to about 35%
there is only one VE table and it is a diagonal flat plane.
it appears to be just running on the MAF
the injector data is incorrect judging by the part numbers on the injectors - 25326903
so I downloaded this 1166898781 file from the repository, I believe it was from a 2000 Camaro
I did however try the injector data from a 03 Tahoe with 24lb injectors and it was idling at 11;1 so I went back to the Camaro injector data, I thought initially these were 22 lb injectors, but now I can not remember.
I'll get to the point, whether I tune in closed loop or open, the error is about 15% at or near idle.
I change the VE and/or the MAF and it still comes back with - taking more fuel out, seriously, like 15% again
I have failed the MAF
disabled LTFT
and put 284 f wherever I thought was causing the stft to stay active. no luck
so I just stopped then with the scanner's vehicle controls
I lock it in third and lock the torque converter, and drive at part throttle on the dyno held at 1600,2000.2400 rpm's, and so on.
can someone please look at these files and report to me where I have gone wrong
I am willing to pay for help or for someone to log in and do a remote control session and clear this up
