SD tune with MAF codes

[Z06PSI]

Should I be getting these codes if I have a SD tune?

Diagnostic Trouble Codes
P0102 "Mass Air Flow (MAF) Sensor Circuit Low"
P1514 "MAP/MAF - Throttle Position Correlation"
P0102 "Mass Air Flow (MAF) Sensor Circuit Low"
P0106 "Manifold Absolute Pressure (MAP)
P1514 "MAP/MAF - Throttle Position Correlation"
P0102 "Mass Air Flow (MAF) Sensor Circuit Low"
P0106 "Manifold Absolute Pressure (MAP)
P1514 "MAP/MAF - Throttle Position Correlation"

The only code you should be throwing in SD is P0102.
Check out tables C3003 & C6101. You will need to build maps to copy these tables & log the maximum values you are seeing. Then add up to 10% to these values & paste into the tables.

Thanks for the input. Well I am a little farther along now.

P0102 "Mass Air Flow (MAF) Sensor Circuit Low"
P0106 "Manifold Absolute Pressure (MAP)
P1514 "MAP/MAF - Throttle Position Correlation"
P1516 TAC code

I am supposed to get P0102 because the MAF is gone from the SD tune. The other three are killing me though. I am getting Throttle percentage of open or closed with the pedal (drive by wire) and manual when I turn the throttle by hand. I am not getting TPS-voltage though at all. Key on or running. I have 4.7-5V on Blue, Green, and Yellow with black wires and have resistance on the other three with no short to ground. Car (02 Vette) starts and runs but as soon as throttle is opened with the pedal then it backfires and dies. upon restart if I do not touch the throttle then after about 1 minute of idling it dies and throws the codes above.

Can you post your tune & a log? Also list what mods you have done .

you need to up your predicted airflow table to get rid of the 1514 code....what mods do you have on youre vette?

Let me capture a tune but I think it is all electrical related now.

Mods.
