Motorsport Electronics ME442 Plug-In ECU Honda S2000 00-04 AP1

The ME442 Honda  Plug-In is the latest plug-in Engine Management System for the 2000-2004 Honda S2000 (AP1).

Aaronyuri from the S2Ki.com forums had this to say about how great the ME221 is even compared to the stock unit (he returned the car to stock prior to selling): “I part exchanged my S2000 for a brand new Civic Type R. I needed a daily with more doors and seats, so on and so on.
Anyway, I removed the ME221, driving the car to the dealer on the stock ECU and it felt lacklustre in comparison. It wasn’t until I went back to the stock ECU did I truly appreciate how much drivability had improved. [using the ME221]”
