GM Part number 12580698
Converted the tune by:
Code:
Engine Calibration.Barometer
{B0301} Min RPM for Barometer update, changed from "1200" to "7300".
{B0302} Max RPM for Barometer update, changed from "4000" to "7500".
{B0304} Baro Offset Factor, modified (1.0 across the board)
Engine Diagnostics
{C6001} Engine DTC Processing Enablers, modified.
Engine Diagnostics.ETC (maf ses lights off, codes on, map codes off)
{C6101} ETC Predicted Airflow, modified. (all entries to 4095 -- max value)
Engine Diagnostics.MAP
{C6301} MAP Sensor Scaler, changed from "80.0000" to "87.0000". (last change - tried a bunch -- 87 = 50 MAP with key on. I'm at sea level. Baro read 79.7, which seems low)
rebuilt the VE as mentioned and to enable open loop running:
Code:
Engine Calibration.Fuel.DFCO
{B3312} DFCO M6 Speed, changed from "200" to "250".
{B3313} DFCO Temp Enable, changed from "104" to "250".
{B3314} DFCO Vehicle Speed Enable, modified.
Engine Calibration.Fuel.Mixture
{B3610} PE Delay RPM Bypass, changed from "3000" to "0".
{B3613} PE MAP Threshold, changed from "55" to "105".
{B3605} EQ Ratio When in Open Loop, modified. ( 14.1 : 20-30 kpa, 12.1 for the rest - big turbo I won't risk 13.0 :))
Engine Calibration.Fuel.Trim
{B3801} Long Term Fuel Trim Correction, changed from "Enable" to "Disable".
{B4205} Closed Loop Temp Enable, modified. (changed enable to 252 degrees F)
Engine Diagnostics.MAF
{C2911} MAF Rationality test, modified. (all values to 0)
I read that the MAF RT should be set to 10 or so, but I have no MAF at all, so I don't really think it matters?
I didn't do anything to the Cranking VE.
Anyone who's done the Autotuning thing run into similar symptoms on the changes?
