I put a stock RXP ECU in a GTX SC today
I put it in my friends bone stock ski and the results were pretty good. The ski increased in top speed by 1.4 mph.
It was running 62.1 stock and 63.5 with my old stock ECU. The biggest improvement was in the acceleration.
I wonder what would happen if i put my old stock intercooler in his ski too

Would love to hear the results with the intercooler!

Thats interesting news Hulk i'll have to keep my eyes peeled for one. In case you haven't noticed i'm dissapointed in my speeds lately.

You'd get an RXT, assuming impeller, pump and plate are identical.
Well, actually you'd get an early 2004 yellow RXP motor.

63.5 mph in a 03 SC with sut the RXP ECU.... it's practically already running at what some people claim their RXTs run....
i'm very interested to hear what the IC will do to it... it'll probably perform identical to an RXT.... downfalls would be no forged pistons, cheexy drive shaft and pump components.... pretty much it i guess?

What did you do about the throttle body? Don't they need to mated through BUDS?

Shibby, i doubt i'll go as far as installing the IC in his ski. His wife about had a fit when we put the ECU in it.
Bankyf, the throttle body isnt an issue. The ECU swapped right over and I just used my lanyard that was originally programmed to my ECU.
I think its only the RR ECU that marries itself to the throttle body.

Hey i didn't think of that. If you have the rotax racing ecu you can use any key but if i got someones RXP or RXT computer then i would need their key. DANG!
