I have an issue with SD tune using 3-bar GM old style map sensor.

Tuner is battling an issue with ELectronic Throttle Body closing when ever it builds boost.

Threshold map table for ET is 105. He set it to zero using EFI live and done some changes but it still commands TB to close as soon as it goes into boost.

Error code is 1514.

Any help is appreciated before we revert to MAF tune.

did he apply the patch for the tcs and such?

calculated torque is based on air flow across the maf in most cases. just a lil fyi

I believe you have to raise the airflow for the p01514 threshold. I'll have to look when I get home. Maybe I am thinking of something else, I don't have my computer to look at a tune.

Can u explain more what u mean by "apply patch for tcs and such".

I'm not sure I understood u there.

ETC has a max threshold of 105.

However, he set table under Engine diagnostics-ETC-ETC to max value, it's above 4000.

Is this your 03? Are you using an X link? Is it the stock 78mm? We could help better if you could post up the tune.

It's 03 with stock TB and no x-link. I will try to pull the tune using my HP tuner and post the file.

But we switch to stock 1-bar map and tuned it SD on stock map to 15 psi for the time being until we figure out the issue with 3-bar SD map tune.

i thought this as on the 08. my bad. did your tuner shut off code p0102?

There was a code for the MAF that he reset but it came again although maf was disconnected completely, unplugged.
