RXP-X - Rotax Racing Stock Class ECU?
Has anyone put a RR Stock Class ECU on a RXP-X before? Wondering how that worked out. What gains if any were seen. Thanks.

there is no ROTAX RACING stock class ECU available for the 2008/9/10 RXP-X,
the 2007 RR stock class ECU will work ( from the wireharness) but will be extrem lean ( as is it mapped for the 215 SC and internal IC )
the new RXP-X RR ECU is the 8800 RPM Limiter Racing ECU, you need lightweight valves and lightweight retainer ( RIVA, ROTAX RACING or Les Cooke)

Thanks Mrracing. I guess I need to keep my eye out for a used Les Cooke stock class reflash then.
