86-89 tpi ecm $85 shipped in the lower 48

 

 

Are there 2 ECMs for sale?

Is that black spot in the upper left of the 259 photo dirt on the case or is the case damaged there?

I can't read the model number in the second pic. Is it a 165 or 259? And the sticker doesn't look factory. Is it a refurb or aftermarket unit?

Have you verified that either of the ECMs work?

Sorry for all the questions but thanks for answering them!

Hello Chris, the first is a 259 same as a 165 but refurbished.
the second one is I believe cardone 77-7165 both for tpi maf.
the case is dirty doesn’t look damaged. These ecms are unknown condition but if doa I’ll refund.

 

If one replaces a, for instance, 1989 305 AT TPI PROM (or entire ECM) with a 350 TPI PROM (or ECM) would that change be evident when a Ca SMOG Test computer is hooked up and the vehicle tested? Does the model year show up on the test equipment? Thanks.

 

The model of the ecm doesn’t show a model in the data stream. The prom does but I think it’s a hex value.
does ca even scan obd 1 ?

 

AFTER, I get my next smog test, I will ask my smog guy (who never cheats) and advise. What is a "Hex value"? Thanks.

 

It’s a binary value the prom uses for scan id.
