Have a MY01 ECU on the MY04+ ?
I have a friend at work that bought a MY01 ecu. He's had it for at least 6 months and still hasn't installed it into his MY04. I'm tempted to buy it from him. Other than the guy that installed one (and tracked it immediately), anyone heard any horror stories about running the 2.2 to 8900rpm occasionally? Billman ?
Thanks

Hell, fuel cutoff is 8200 on the MY04. I'd say that's a given. Where I work, the mechanical engineers over-engineer EVERYTHING by at least 15%. I'm just curious if anyone that's actually done this mod is now sorry.

That makes no sense. Why would the F22 be weaker than the F20? They just increased the stroke of the F20 to give it 150cc more displacement.
I crunched some numbers and based on something I read on a S2000 page on the Japanese Honda site. A F22 running at 9k rpms generates a higher piston velocity than a Honda F1 engine at 18k rpms. Take the stroke of the engine and calculate how far the piston travels in 1 rpm, and then do the math. I did it in MMs of piston travel per second, and the F1 3 liter V10 at 18k was the highest, and stock F20 at 9k was next lowest and a stock F22 at 8k was a little lower. An F22 reving to 9k was higher than the F1 car.
