Rev Limiter
I currently have a 502 mag mpi thats bumped to 509 with a M3 Pro Charger 730 hp. My rev limiter seems to be set at 4700/4800 rpm"s. i thought it was my bravo 30 prop but after a few trial size props its stays the same. i even put a new throttle position sensor in it, and still same rpm's. How do i reset my rev limiter to higher rpm's ? thanks

You will have to have the computer flashed by whipple or another company like that. I thought the factory setting was higher than that but not by much. Maybe thats all you can turn with that motor/prop combo. Have you tried a 28p. A stock merc 30 is pretty hard to tun. I run around 750hp and had to race lab a 30p to run it.

Yes i ran a 26 and 28 it made no diffrence in the rpm"s the motor is all new. just not sure why they would set it at such a low rpm. Its a 98 Baja Boss 27. The set up now is a drive breaker.I really need more rpms to take the load off the drive.

The rev limiter is in the ECM, you'll need to have it reflashed.
|
do you know who set up the tune that's in it now?
|
Precision Marine, My build sheet says custom calibrated for cam and blower 5600 rev limiter ( 750 ) idle timing set at 8 degrees with COMPUTER LOCKED. Not sure why i only see 47-4800 rpms max, no matter what i do.

There's a noticeable feeling when you bump the rev limiter. Im under propped with 23" 3 blade mirage plus. I hit it between 51 and 5200. Totally stock 502s. You sure your tachs are correct?
|
I have bumped it in other boats. Im nowhere near it in the Baja.
|
I'd get with Precision and see if they would be willing to read it and confirm the setting
