The tach will read higher. Did your rpm's go over 8000 before the ECU swap?
What other modifications do you have other than the ECU and what kind of ski?

Thanks for the correction RD. Should have waited until I found out what model of ski before I answered.

Try this site for finding the appropriate model...Also be careful now because if you have the new ECU and with your current set up, you might be banging the limiter and running way lean and not even realizing it. You really need to get that tach to get your true RPM reading. Your doo must be hauling....Nice mods!!!!
