it could be done using a map sensor that uses same signals as the factory maf, it should be something simple like 1-5v

Wow its a lot of money to have to spend to clean up the engine bay...
But yes, it will require a different ECU. Or as suggested possibly MAP would be the easier way..

I believe the MAF-less tuning on the early 5.0L Falcon EECs has been done using Alpha-N tuning (using TPS and RPM) rather than Speed Density (MAP sensor). I dont believe the MAF-less tuning has been succesful on anything post EL Falcon though...? Give Chiptorque a ring.

its possible to do it in the E series coz they have an ECU capable of dealing with it (EB's had a map sensor as well as the MAF) but they changed to a dif ECU in the AU
how would you go about using the six cylinder MAP sensor on the V8??? |

Gary, AU1XLS's ute was a mafless tune set up, running through a Heltec ECU.Was a bit of a pain to get set up but made some good numbers in the run in stages but was pinched and blown up before it ever made its full potential, send him a PM and he can fill you in what it took to get it to run rite. Here's a bit of the original video we did messing around with it, was Tuff as

I ran my auxr8 for 25000 very hard and faultless km mafless using a tuned stock ecu.
I have since gone back to a maf as I scored a free one.

i dont understand whats the point of a mafless tune? is that because the maf is restrictive?
