I did a quick search and couldn't find anything about a PnP Megasquirt unit for an RX-7. I have a PnP unit on my 92 Protege, I'm in the process of getting a PnP unit for my 88 323 GTX, and I'd like to Megasquirt my 86 TurboII.

Has anyone ever made a Plug n Play MS unit for the FC?

 

I made one a few yrs ago but your best bet is to look at the DIYPNP.

 

I have a PnP for an 88 Turbo II (same gen as yours). There are a few posts out there for the 2nd Gen PnP. Support for it was slow in the beginning. I'd be curious to see how you do with thePnP....

I biult one for the S5 and am in the process of installing and testing it.
