My MAF is currently ziptied in my engine bay with a AIT sensor spliced into the wiring. The ECU is in limp mode with codes 0201 and 0202 (low MAF voltage)

I assume this is due to the MAF not being in the intake plumbing.

The Fcon has a option for sending the ECU a false MAF signal..


Can this be done with the Haltech?

 

Haltech is setup to limit the MAF values, but is not currently setup to output a MAF value from nothing. What is happening that you describe as 'limp mode'? What year is your car, and is it auto or 6spd?
