is anyone running a 2.2L in their track car?

I remember Slick Rick was and I thought they limited it to about 8500rpm and still had engine problems.?

I am trying to make my car legal for Honda Challenge and am having trouble figuring out how to get beyond 8000rpm with the stock 2.2L ecu. I can put in a AP1 ecu and go to 9k but I think that will kill the engine fairly quickly won't it?

any input is appreciated.

You do know you can shift before you hit the limiter, right?

It's hard to figure out what you're asking. But I'll take a few stabs:

Without doing a lot of internal rebuilding, I wouldn't up the redline of a 2.2 liter engine. I understand why you would want to, but why would you need to?

I'm sure it's not hard to change the electronics to up the rev limiter, but I doubt it's a good idea.

A far better idea, if you're looking simply optimize a 2.2 engine, would be to drop the VTEC engagement point a bit (if legal for what you want to do). Personally, I don't care what the redline is, only what the useful power band is. If the VTEC engagement point had been lowered proportional to the lowering of the redline, VTEC would engage at 5667RPM, to give you 1/3 of othe total band in VTEC.

Lots of folks track the 2.2 liter cars, since all U.S. cars since MY2004 have had the 2.2 liter engine.

8500 max on the 2.2L and still expect a yearly rebuild.

I wouldn't run the AP1 ecu. just use your EMS.

that is sort of what I was thinking....

unfort my AEM EMS is illegal in my class so I have to do something different.

I can just run the stock AP2 ECU and it will shut off at 8100 or whatever, but I was hoping for those extra 200-300rpm..... guess I should not do that.

I think I am heading towards Greddy Emanage Ultimate (it has to be a plug in EMS system) which allows a fair amount of tuning but I am not 100% sure about changing the rev limit.

I was told by a couple of people that the AP2 could handle 9k shifts, but i leary....

Did anyone on this board ever buy the Hondata reflash to lower vtec engagement and raise redline on their 2006?

I believe Billman has helped convert and service a few 9k AP2's. Of course street miles are not the same as track miles, but you could query him for some insight.

krazik

exactly its not the same. I've talked to the people who tune and race them. ie shawn church, karner, me, davepk.

Don't do 9k unless you want to use a couple motors a season..

What's going on with rylan.org?

Along those lines I bet this would meet your needs: http://www.hondata.com/s2000kpro.html
