Can anyone help id who's aftermarket chip upgrade this is? The seller told me back in 2000, but I can't remember who did the upgrade. I was told it was good for 14psi. I thought he told me it was rx7 Fashion, but Ive searched hundreds of threads with no luck. And Rx7 fashion doesn't seem to exist anymore.

Also my car is an automatic. Almost every thread I read said there aren't any ecu upgrades chips/reprogramming available for the auto. That's scary!

Well it seems I have one.

The sticker on the cover reads "Engine Management Systems" and the sticker on the eprom reads "MD Racing Ent rx70844.512" See Pic

Any help would be appreciate

 

Call and ask the seller.

 

I'm gonna go out on a ledge and say MD Racing Enterprises.
