Why is the c-usb cable required when doing bluetooth? If step 1 is omitted, should we expect bluetooth connection issues? For me, it will pair and go into 'connected' state. Then it quickly goes...

Correct. I wasn't tuning VE with MAF and DFCO enabled. My VE table is tuned. I re-enabled MAF. Then I collected a log doing WOT. That shows the lean condition even with the relevant cells in the VE...

Here's my tune

I'm logging throttle% and fuel trims. When going full throttle I observe the short/long fuel trims go to zero and the commanded AFR drops. The AFR drops to exactly what the stoich/PE multiplier...

Yes, I put a new fuel filter in. I also bought a glowshift fuel pressure gauge and have monitored while WOT. The pressure never waivers below 58. I think the fuel supply is good, this was the...

Yes, when I bump up the PE multiplier the wideband reports a lower AFR. So it does respond to that. But that also lowers the commanded AFR. I'm already at a commanded value of 10.6, which seems low...

Here's a log one one pull. Duty cycle isn't going above 70%. Sorry, I should have mentioned that in the post.

FWIW, I was have some warm start idle issues. I wound up adding 2 degrees of timing to the idle advance table and also tuned the base idle airflow table. My warm start idle issue seem to be gone...

99' Vette with a mostly stock LS1 other than a stage 2 cam upgrade, normally aspirated. I've tuned the VE table but the AFR is still too lean when under power enrichment (WOT). While I can command...

I have a 99' Corvette and when I read the PCM and view the tune in VCM Editor it shows the platform type as GMT530. My understanding is the corvette is a Y body, not a GMC Truck. VCM Editor gives...

Recently installed a stage 2 cam in my LS1 and have tuned the idle. I have tuned the Base Running Idle Airflow, ST Adapt Airflow Max, both over and under speed Idle Adaptive Spark Control, and Idle...
