FAST Dual Sync Distributor with Accel DFI Gen 7

[buzzinhalfdozen]

Ok well it looks like you'll require some assistance from someone with Accel experience. I'll assume speed density tune? If so what's your MAP sensor reading (possible vacuum connection or restriction in hose) maybe take a look at that since it's a big input for fuel strategy and you're saying IAT ECT sensors read normally. Is your TPS zeroed ? A quick check for the MAP is see if it reads same as BARO sensor (should be close with engine not running). Best bet in my opinion is to get to your logs and retrieve them your issue will almost certainly show up. Good luck. Joe
