Hey everyone,
Wondering if anyone might be able to shed some light on an issue that I ran into with my build.
I'm using a LS6 from a 2004 CTS-V for a miata swap and have also swapped to an LS3 style MAF and switched the DBW throttle body out for a DBC throttle body from an express 3500 with new IAC valve and TPS (all delco). I am running this from the factory CTS-V PCM which is capable of driving the IAC (I can see in VCM scanner that I am in fact seeing the position reading change for IAC) with the factory OS. I can see the TPS reading correctly from 0.4% - 100% with the throttle pedal as well.
One odd thing to note is that O2 B1S1 is reading as "not ready" while B2S1 seems to be "ready" with no issues. They both have voltage.
I finally got to the point of the first test start and it does start just fine but won't find an idle and drops out/stalls pretty much right when it would want to settle into idle.
So far in HP tuners, I've:
- Turned off VATS
- Changed 1 to 0 in ETC column under System Options
- Did my best to copy the idle tables from the express 3500 tune to the CTS-V tune
- Removed the emissions systems from the DTCs under Engine Diagnostics
- Removed secondary O2 sensors
Anyone have any ideas where to turn from here? This is my first car I've worked with Hp tuners on so I'm fairly new to the interface, I'd always used megasquirt for the car in the past.
Here's my tune file as well as two logs I took while trying to start the car today (the second one to monitor the O2 sensors and make sure they were working):
