Re: EFI question
Honestly, as long as the wiring harness is set up correctly for the ECU, then a manual computer will work with an auto and vise-versa.Originally posted by twister01 View Post
Back in the day, we were told to run an auto computer with a manual because the auto AOD was such a dog that the auto ECU had a better fuel/spark curve to compensate. That's before tuners were available...
There is a jumper wire on the Hego harness that is one way for Manual and another for Auto...Last edited by 904Bronco; 12-17-2010, 06:13 PM.2002 F250 Superduty, 7.3 241,500 miles and counting
