There is no GM-format data for FAST injectors, they're made for aftermarket systems where none of that stuff matters.

Well that's not how you do that, use the one column from both tables that matches your base pressure (408kPa will be close enough for 58 PSI).

CMP counts did increment in the runs-on-starter-fluid log.

And figure out what's wrong with the MAP pinout, those are often swapped around too. Some of the swap harness companies don't realize there are multiple different pin arrangements for different...

OK, so how did this file get a 2-bar speed density OS applied? That's your problem. The new VE tables are filled with zeroes. The defaults for MAP linear/offset also get changed with the OS.

Depending on what components you re-used in this swap, man alive do you have a bunch of DTCs that need attention. EVAP? ABS? BCM? Cats & downstream O2s? There's also a theft deterrent DTC still...

Why does MAP never change from 59 kPa? Why 'OL - Fault'?

Up thru 2007 they all kept the same wording about loss of CMP behavior, 2008 it's strangely not mentioned one way or the other, then 2009 it changes to what's quoted up above about being able to run...

Log shows it in closed loop, the O2s are switching, and trims are working so I don't see how it would be possible for it to be 'using too much fuel'. Trims will bring it back to stoich, it can only...

Your tune file has all the DOD bullshit still turned on.

Does it look something like this?

E40 and earlier have this in the manual:


By 2009 that language is gone.


...meaning that unlike the older stuff the engine will continue to run if CKP is lost.

Wouldn't a msising CMP still leave it with only a 50/50 chance of guessing #1 TDC, and at least occasionally it would guess wrong and give a long crank or popping/banging and a no-start? Even if the...

...at which point if you don't have the tools & SPS subscription it's way cheaper to buy a used ECM of the correct service number pre-SPSed to a VIN you supply.

I assume you can only be asking that if you have not opened the file and looked at it, which seems like would be easier and waste less time than if I went through a whole sales pitch explaining its...

I do not understand the thought process that lead you to a supercharger, with a 1-bar OS and MAF. MAF sucks. MAF especially sucks the more modifications you have made. Even if set up for 'MAF only"...

OK, so far you've narrowed it down to "a truck". Can you give a YEAR, a MAKE, and a MODEL? So I can go into the GM service manuals and find your actual diagrams?

No, because a 2012 has data in a completely different format than your Gen 3 uses. There is a link at the bottom of all my posts with a spreadsheet that has all the Gen 4 injectors converted into...

Not one single change to fail the MAF was done correctly. Min RPM, high/low counts, dynamic disable/reenable, the DTCs...

Nobody knows what you are working on if you don't tell us.

A "sensor" that has only two pins is not a sensor, it is a discrete on/off switch. Feels like I already said that. All the A/C pressure...
