For use with a boosted miata running stock ecu. Pulls timing up to 6 degrees when in boost to prevent detonation. A little basic but it gets the job done. I have not personally tested it but was told it worked when uninstalled. Asking $100 shipped.

 

You didn't get this at the NJ Miatas end of season meet, did you? If so, I can verify it worked when pulled.

 

Nope, it actually came from somewhere in Georgia

 

Hi there. Do you still have your MSD ignition retard for sale?
Kind regards Søren

 

Yes, I still have it!

 

I decided to go Bipes ACU instead, but thanks
