I'm pretty sure the harness is a 91 everything in the engine bay as far as connectors are 91 but if theirs a way to check for sure let me know I can do it now if needed I'm 90% sure this ecu was modified for a 90 car as it's what yr car it came out of but the tach works fine didn't have to do anything woth the coil either because my mgi and coil are all 91 style. As far as dead times for injectors I changed them to get the idle afr around 14.7 as they were very rich when set to ecm link wiki suggested to start at I'm about 160 counts off from the but figured I am having other issues that's causing it to be so far off the nb o2 I reused the old one from the stock motor seeing I didn't thinon their was any issues with it until I started logging but my guess is it hasn't been cycling this entire time..keep in mind all these issues started when I installed the ecu so the idea the pins need swapped is catching my attention here.. I wondering of the idle switch isn't activating because ecu can't read it could that possibly cause the o2 to stick at .20v?
