89-90 Bronco II - C9C1 ecu HW: EFI-SD24A

Unread postby decipha » Mon Feb 05, 2018 12:48 am

I got a customer that came to our dyno day last year with a pinto he swapped the 89/90 bronco II ecu in. catch code is C9C1 hardware code EFI-SD24A.

its a v6 throttle injection speed density setup that controls OD and lockup on the early A4LD.

Anyone know what strategy this uses? It looks like I'll be making a half ass def to log and tune it.

The car runs fine up until 3k rpm where it shits the bed dumping fuel. Surprisingly the little 6 was making some big torque last year.

Anywho, just thought id ask of anyone had any details maybe save me a few hours staring at the screen.
