Disabling VE, MAP, AFR, etc from fueling
I want to be able to manually control the pulse width for an engine. I don't want any of the enrichment, VE, MAP etc to adjust the pulse width. I would like to use the REQ-FUEL along with open time as my controlling parameters. Does anyone know how this can be accomplished. This is a test engine on a dyno.

michaeldp,
- Set every cell in the VE table to 100.
- Set the TPSdot and MAPdot values very high (as high as the INI will allow, try 9999999 and the software will let you know what the maximm is).
- Make sure X-Tau is disabled.
- Set the voltage correction to 0 msec/Volt.
- Connect the coolant temperature sensor lead to ground through a 220 Ohm resistor (this will give an indicated 170 to 180 degrees F, so warm up enrichments won't activate).
- Connect the intake air temperature sensor lead to ground through a 3400 Ohm resistor (eliminating air density compensations, and setting the temp to a constant 70 degrees F - the MS standard).
- Disable the 'ASE Hot Start Enable'.
- Set the barometric corrrection to 'None'.
- Make sure you set the EGO controller authority to zero.
I think that should do it, but I'm sure others will chime in if I missed something.
