If you have the knowledge or time to wire it into your harness then it might be a viable solution, but I'm getting really tired of thinking Megasquirt is some kind of easy plug and play solution; it's not. I have a friend who put it in his Escort and it was a lot of work, the car runs fine now but it took a lot of time.

Octane boost wouldn't have that much effect on the A/F ratio unless he was running C-10 or better. Did they try to advance or retard the timing at all before he refused to run the car anymore?
