Just curious if anybody can tell me what this was used in and why no resister chips?

 

Must be from a lt1

 

You can upload the .bin to bithost to identify the bcc .

Unfortunately, it was reprogrammed to an AUJP and sold by one of the large mail order houses. I was invoked to make it right and that's just what I did. I have a couple LT1 memcals on my desk and they have resistor chips on them. My guess is an application that doesn't require cylinder select?

 

I don’t recognize the knock filter identification M . It could even be from a lt5.
I believe this is for a cylinder displacement application a ecm that only uses one cid.
Looks like it should be junked since no I’d is available.
A 90-91 vette and anjf and aujp are R as the second digit of the knock filter followed bye the manufacture date. I believe the first digit is manufacture location or run.
A 305 uses P to identify the knock filter.
This memcal would be from a 91 made on the 322 day of the year I think.
