ECU Year | PID | Parameter | Action | Comments |
1993+ | SW_MLK | Force TCC Locked - Override | set scalar to 1 or "set" | Forces TCC hard Locked |
1993+ | Force Trans Gear Lock - Override | set scalar to 1 or "set" | Forces the transmission to stay locked in the "Gear Locked" value | |
1993+ | Gear Locked Override | set scalar to 3rd gear | Gear locked into when the "Force Trans Gear Lock - Override" is enabled. |
ECU Year | PID | Parameter | Action | Comments |
1998- | FN320A | Open Loop vs ECT | Set y-axis to all 0s | Forces open loop when perload is exceeded |
1999+ | FN311 | Open Loop vs TP | Set Y-axis to all 0s | Forces open loop when relative throttle position is exceeded (3.8 is approx maximum) |
PID | Parameter | Value | Comments |
NIOLD | CL Neutral Idle Fuel Max Time | 1 | CTHIGH must be exceeded to function |
NIHYS | CT Neutral Timer Hysteresis | 1 | value of 0 will disable functioning |
CTHIGH | ECT Min Hot Start | -252 | ECT must exceed this value for the CT Timer to count up |
TEMPFB | ECT Min Warm | -254 | set to keep temperature consecutive |
CTLOW | ECT Max Cold Start | -256 | set to keep temperatures consecutive |
PID | Parameter | Value | Comments |
FN338 | Decel OL Perload | set y-axis to the minimum perload value you want to allow closed loop | OL is forced BELOW these perload values (not in fox ecu) |
LOLOD | Low Load OL | 30 (does not exist in newer ecus 94+) | Will force open loop when perload is less than this value, the minimum perload closed loop clip |
LOLODH | Decel OL Hysteresis | 3 | value of 0 will disable FN338 |
ECU Year | PID | Parameter | Action | Comments |
1999- | FN320A | Open Loop vs ECT | Set y-axis to maximum (200 or 2.0) | Forces open loop when perload is exceeded |
1994+ | FN337 | Open Loop vs RPM (warm) | Set y-axis to maximum (200 or 2.0) | Forces open loop when perload is exceeded |
1994+ | FN338 | Open Loop vs RPM Decel | Set y-axis to 0 | Forces open loop when load falls below this threshold |
1999- | FN311 | Open Loop vs TP | Set Y-axis to maximum (5.12v or 1020 ad cnts) | Forces open loop when relative throttle position is exceeded (3.8 is approx tprel maximum) |
1994+ | FN513 | WOT TPREL Threshold | Set y-axis to maximum (5.12v or 1020 ad cnts) | sets the wot flag and forces open loop when tprel is exceeded |
1993- | THBP5 | OL TPREL Threshold | set scalar to maximum (5.12v or 1020 ad cnts) | forces open loop when tprel exceeds this value |
