I'm tuning my new 427 boosted by a YSi supercharger on my 2004 vette. I am having issues with going full throttle with the current tune. Here are the related codes;
P0068 - MAP/MAF - Throttle Position Correlation (Old) (History) (Immature)
P0102 - Mass Air Flow (MAF) Sensor Circuit Low Frequency (Old) (History) (Current) (Immature)
P0103 - Mass Air Flow (MAF) Sensor Circuit High Frequency (Old) (History) (Current) (Immature)
C1278 - TCS Temporarily Inhibited By PCM (History)
Presently I’m running a 2 bar tune (plan to upgrade to a 3 bar once I have thing running good).
- I have adjusted the P0102 and P0103 from no mil light to mil on first error with no luck (I ran no mil light on the previous engine tune up to 12lbs of boost with no issue). I have also changed the KPA of each.
-I was running the P0068 error table at the max 4.1 and it would still go into reduced power. I brought it down to 3.0 with no luck also.
I have attached the tunes I’ve tried with the scans showing the Reduce Power happening.
I’m at a loss right now…..
