What rpms should you run at, and at what rpm are the rev limiters set at with these ECUs

Thanks guys, I know this is here in the forums somewhere but when i search ECU the" Sorry - no matches. Please try some different terms. " comes out.
Thanks

Hope this helps

Is that the limiters or were you want to be running at?

[Shibby1485]

those are the limiters...

you want to be about 100 rpms below the limiter for optimal speeds. however, wth the 8600 rev limiter RR ECU, you want to be down about 8400 with a stock valvetrain. if you upgrade your valvetrain then they say u can play a little more on the edge like 8500-8550

Thanks Shibby

But i think the stock ECU rev limiter is a bit higher because i had all the stage 2 stuff on except the 15/20 and couldn't take it, i had to try it out and it was at 8260-8280 . So I think its at like 8300 or maybe a little more, i know ive hit it jumping a wave, but its to fast to see were it cuts off.

i agree Manny R.... seems the 06 machines are able to spin more rpms than prior models tho. i've never ever seen a 04 or 05 machine do anything more than 8200 in the water and hooked up on glass... sure it'll spike to 8300+ when it gets unhooked, but never while under way on glass.

so yes, i tend to agree with u that the stock ECU rev limit is debatable bc many 06 skis are pulling over 8200

i wonder if it's a gauge accuracy thing or a ECU thing... only 06 skis read in smaller 20 rpm increments...

I can say that for the 2005 RXP/RXT stock ECU in my GTX that I`m seeing 8100 max, at top speed...I think that`s cherry!...PR...

can a stock rxp rev to something like 8500 rpms for about .2 seconds during acceleration with the 8200 limit?

[MANNY R]

If your hooked i doubt it, unless you got major prop spin. But if you jump or just got the hull out off the water for a sec it could happen. I've seen it.

Running any of the two RR ECUs will it still beep if the exhaust temp is hot and/or if anything else is wrong. Like the stock ECU that beeps and says whats wrong?

Or will you lose these codes and it will not notify you of any problem?
