I have an 87 fc3s and am pretty possitive that the ECU is fried. I was woundering if I could get a 88 ECU and have no problems in hooking it up and if the specs in the 88 ECU are compatabl;e with the 87. Further, is it possible to use a TII ECU instead. I do plan turboing my rx7, but don't have the money for all the nesseities. So is it possible to use an 88 and above TII ECU on an 87 N/A?

 

No, you can't just plug a TII ECU in. You'll run very lean. You need an N326, N327 or even N338 (vert) ECU. Year does not matter, as long as it's S4.

 

Thanx. Can you put TII acssesories(turbo, intake, sensors, ...ect...) on N/A irons?
