Hello. I have a pontiac firebird 3.1 v6 from 1991. I buy the car and the ecu missing.
can someone help me find out which ecu I need. if I order another ecu, I have to make immo off or go plug and play?
vin number is 1G2FS23T0ML246805

 

Manual or automatic? I have a few 1227730 ecms and memcal chips.

 

Hello. Its automatic. I need ecu 1227730. Its will plug and play?

 

I have 2 memcals for the 3.1L automatic azty is the latest for 3.1L automatic transmission. I have a stack of 1227730 ecms. These have vats security enabled I can disable that if you like. This would be a plug in ecm but if you have other issues would need to address them to get your engine running. Especially if this car has sat with stale fuel.

 

Sent you a pm with shipping quote awhile back , still interested?
