8220-40 on stock ecu
I had my wife's rxt out last weekend and ran 8220 rpm's consistently and bumping on 8240 and had no signs of hitting on the rev limiter ( that I could tell). The ski ran 8180 all thru the summer heat. I know the cooler water temps and air temps are responsible for the gains, but I thought the stock ecu had a limit of 8200rpm's. I was wondering if I should go ahead and add 1mm or let it go since I'll probably only ride 1 or 2 more times this year. The second thing is, do I have a problem with my ecu or tach. I'm running a 14/19r untouched w/o tuning rings. I've been tuning the ski's to the high 8100rpm's for the summer heat, should I lower the rpm's? We mainly use the ski's for cruising down the inter-coastal and riding the lakes. Also, could someone tell me what the ski does when its on the limiter. Does it miss or stutter?

Its not good to run so close if you can avoid it, it can cause a blown headgasket. What u will usually see is a sudden drop of 50 or more RPMS when close to the limiter when it actually hits the spot.
