Moving old Holden Tune parameters to new operating system

[68problemchild]

Hello All. Here is the old holden tune copied table by table to the new speartech tune and operating system. LSX 376 mated to 4L70E in one of todays operating systems.

The original speartech barely ran. After I copied the airflow parameters it began dumping tons of fuel which is a problem I previously had (SpeartechMod1). Gas tearing eyeballs. Lol.

Any ideas appreciated and or a decent LSX tune to start with that runs. Lol.

Thanks all in advance. Appreciate your years of assistance here!

Here is the car logged today with the original speartech tune. I ran it stock for safety purposes since the tune changes were so numerous. My car continued with the crazy intake pop at start. I had hoped the new controller would rectify this. The O2 sensors are new (only have bank 1, sensor 1 and bank 2, sensor 1) and the harness was sent in and supposedly tested. However, an issue may still exist.
My current theory is that it is dumping so much fuel into the intake, remnants are exploding at key on before start. So I ran the car as is, which was super rich. Log 1.

Next I ran it with LTFT set from 1.3 and .7 limits to "1" so no change could occur. I also set "engine coolant temp for closed loop" to 256 (Max) from its original -40. The car seems to run normal thus far.

This log shows symptoms of the front NBO2's being crossed/swapped (i.e. left NBO2 trimming right bank, right NBO2 trimming left bank).

Frame 13210 looks like they are cutting out?

[joecar]

Looks like Bank2 goes into CL-Fault mode, this means the ECM may be using Bank1's NBO2 to trim both banks because it detected a fault with Bank2's NBO2...

I don't know how the ECM figured this out seeing that both banks were pegging oppositely.

Also:

GM.IBPW1/2 and CALC.INJDC1/2 are the wrong injector pids for E38...

GM.INJPWB1/2 and CALC.INJDCB1/2 are the correct ones (the DC pids are from the E38 calc_pids.txt that we're working on, see earlier in this thread).

Hello. I cannot seem to locate this in the pid selection files I have on my pc. CALC.INJDCB1/2

Do you have a pid selection file I can use with your preferred pids?

Thanks so much!

Hello all!

Log from today with O2's switched. This is still the original speartech E38 tune. I did get one of your pids changed Joe. Thanks in advance for all the help!

Hi Pat,

The calc_pids.txt file for that is in the E38 Calc.VET Volunteers thread, let me find it...

Hello Joe. Any luck with that PID? I just prefer to use your dashboard since you know what to look at more than myself.

Also besides shutting down the O2's and the LTFT's anything else needed to run open loop in the interim? Eg shutting down STFT's?

Thank you!
