ECM Issues - ZR-1 Net Registry Forums

ZR-1Mike · 10-05-2017

Hi all! I started having some "unrelated" problems a few weeks ago concerning the secondary injectors and fuel pumps and got that sorted out and today I had a top flight Corvette tech look at the car and he determined that I need to replace the ECM. Now we're on a search for an ECM for my '91 though I know that they're nearly impossible to find. Has anyone here had theirs refurbished and if you have can you recommend a good company?
I'd again appreciate any help from out there!

That's the first that popped into my head, too.

If you find you have issues with your ECM contact Marc Haibeck. I believe he had a couple repaired

What problem are you having that they feel the ECM needs changed out?

They're Out of Stock. Thought it was too good to be true.
