If pinouts between the GMPP ECM & a productin car ECM was different, then would seem replacing one with the other cause it to throw error code(s), but it doesnt other than the P0315.

If pinouts between the GMPP ECM & a productin car ECM was different, then would seem replacing one with the other cause it to throw error code(s), but it doesnt other than the P0315.
Then if it was something mechanical causing it to spit/sputter it should do it with the GMPP harness as well....?
The GMPP ECM doesnt give me a P0315 error, idles fine with it.
I said "it runs", but meant to say it will start, spit & sputter & die. Not sure I can keep it running enough to do the relearn.
So discovered I had to do a full write, not just write calibration to set the VATS configurations. It runs now, I keep getting P0315. It is a new ECM, is this normal? Other one I had on it didnt...
These 2 "VATS Patch" are set to "Disabled" and it doesn't act like it wants to fire at all. What am i missing?

I am trying to use a production '09 E67 CTS-V ECM with an LS2 & GMPP harness, but cant get it to start. It runs with a GMPP E67 ECM, but I need/want to use a production one for features it has but...
Does anyone know for a fact if a production E67 ECM can be used with a GM Performance Parts harness in place of the GMPP E67 ECM?
The harness I have uses an E67 ECM & I have one for a CTS-V, I need to figure out how to tune it to ignore the fact that some of the MAP, & O2 are not there, as well as other OEM features that are...
Long story short. Have LS2/LS3 heads, LSA supercharger with GMPP harness, T56, Added PWM fans, but GMPP ECM wont control it, can I use an CTSV ECM/OS on this & tune out missing map sensors or should...
Anyone?
OK HPT experts, got a dilemma.
I have 2 different E67 ECMs, one is GMPP & the other is 09 CTSV, I can/could write to both of them without issue. But I mistakenly did a "Write Entire" of the GMPP...
P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
Car has been sitting, has not been run hard, I changed camshaft & added supercharger. and now get this P0016,...
Maybe I was confused on what ECM i was using above when I sad the GMPP ECM doesnt get the P0016 code, but in fact it does.
I tried a different cam pos sensor, no change. Checking wiring at...
Looking for a pin-out chart for '09 CTS-V E67?
Anyone have that? Thanks
What kind of files do you want dude?
If I run it with a GMPP E67 computer, I do not get any error code.
Long story short.
Engine is 2008 TBSS LS2 (with LS3 heads, LS9 cam, LSA supercharger), harness is GMPP LS2 controller kit harness, ECM is 2009 CTS-V.
Immediately after writing new tune it...
Do you remember which wires you switched? I know old post.
Thanks
If it still has the Trailblazer SS OS, would it have settings to change to a manual transmission at all or would that not even be available?
Currently it is set to manual, & through the scanner...
The only thing I have for the Trailblazer is the ECM.
Looks like the GMPP throttle pedal is the same as what is used on Cadillacs. Would a CTS-V OS work?
Agree.
It was Trailblazer SS, licensing says 2007, but i was told engine came out of 2008.
It is 0-63lb.
Here is my setup.
