Limitedslip7 Posted June 28, 2012 Report Share Posted June 28, 2012 Well I just so happen to have a brand new Rotax Racing "Stock Class" aftermarket ECU for sale that will plug right in. Rotax claims +10-15 HP throughout the powerband and the rev limit bumped up to a level still safe for stock valvetrain. Designed to be used with stock injectors and valvetrain. This ECU is $1400 from RR, I've decided to just keep the ski the way it is and dump the money into my Superjet instead. I'm pretty sure this ECU will work on any 2004-2006 215. Asking $650 OBO...

Limitedslip7 Posted June 29, 2012 Author Report Share Posted June 29, 2012 Appears to be 1503... Quote Link to comment Share on other sites More sharing options...
XChris1632X Posted July 1, 2012 Report Share Posted July 1, 2012 Correct me if I'm wrong but I think that ECU is only good for 04-05s. Did this come on the ski you bought? Quote Link to comment Share on other sites More sharing options...
Limitedslip7 Posted July 1, 2012 Author Report Share Posted July 1, 2012 It came with it, but is in original packaging and has never been installed. You could be right; I will email RR and get the exact details... Quote Link to comment Share on other sites More sharing options...
turbospec29 Posted July 1, 2012 Report Share Posted July 1, 2012 I think this is for an 04-05 also. Quote Link to comment Share on other sites More sharing options...
XChris1632X Posted July 1, 2012 Report Share Posted July 1, 2012 06's have a different ECU. What year did this come programmed for? Any other mods you are foing to get rid of? Quote Link to comment Share on other sites More sharing options...
Limitedslip7 Posted July 2, 2012 Author Report Share Posted July 2, 2012 Came programmed for a 2005. No other mods as of right now, unless you want a free but leaky Riva intercooler... Quote Link to comment Share on other sites More sharing options...

I will think over the ecu. I haven't been riding my RXP much because I know I am way overdue on needing to address the valves. $1200 just for the valvetrain upgrade is just hard to swallow, especially since if I do that I'm going to want to go back to the big charger and back to the quest for big speeds. I was originally thinking about going to a more aggressive ecu as well. Part of me is enjoying the ski de-tuned but I don't think that's going to last past this year.

I know if I could start over I would have gone with a simple xcharger and just raised the rev limit with an ecu or reflash and valve springs, get right around the same speed im at now with the big charger and stock limiter. I feel like it would be less maintenance. Quote Link to comment Share on other sites More sharing options...
Limitedslip7 Posted July 2, 2012 Author Report Share Posted July 2, 2012 I've read many people are getting good results with shimming the springs if you aren't planning on a major increase in RPMs. Quote Link to comment Share on other sites More sharing options...
Limitedslip7 Posted July 3, 2012 Author Report Share Posted July 3, 2012 Got a response from Rotax Racing, they said it is for 2004-2005 models only, 8500 RPM limit, stock injectors, stock valvetrain. Quote Link to comment Share on other sites More sharing options...

I feel like it would be less maintenance. That's exactly why I got rid of the big charger. I ride in chop more than anything and it comes unhooked way too much. It got to the point that I cringed every time. Who knows what I will do. I've read many people are getting good results with shimming the springs if you aren't planning on a major increase in RPMs. The valvesprings arent my major issue, its the valves themselves. Pre 06 valves are hollow and prone to failing. I just don't see a point in dumbing $600 in a valve job and not doing $550 in springs and retainers while I'm at it.
