Ecu - ircm

[40BelowSummer]

Quick questions, my car is missing the ECU and the relay module IRCM/CCRM whatever and I cant remember what code my old one was (M?).

I need to order one of each so I can get this ****** back on the road.

What ECU and CCRM should I look for for my 1990 MTX? I have a TwEECer RT I will use with the computer.

Thanks guys!

Everything ya need to know bout ICRM (CCRM) read the whole thread first it will give you your info!

I found this last week with the search button think it took me a total of 1 1/2 minutes to find.

You need the letter M for your gen I.

Got that, thanks.
M code was used for 89-93 MTX
J code was used for 93-95 ATX
D code was used for 94-95 MTX
R code was used for 96-99 V8

Cool, now how about the ECU?

89 MTX B9B
90 MTX B9B1
91 MTX LOS
92-95 MTX X2J

These are non Cali computers.

Not having used a tweecer, I would make sure you get a computer that has the most support from tweecer. Might be best to get an X2J
