ECM identification (can i have de right ECM calibration checksum) Hitting rev limiter
First:
Boat: Baja H2x 2001 (4 people + 1/2 tank) temp 7degree celcius
Drive: Bravo 1 , 1.50 gear ratio
Prop: Mirage plus 23p
Top speed on the rev-limiter (66-67Mph)
Engine is a 454 Magnum MPI 2000 (385hp)
RPM range: 4600-5000
Rev limiter (supose to be) : 5100-5150rpm
Last week end i have tested my new boat on the river, I try a WOT pass and a 4650-4750 i hitting the rev limiter. Is below 5100 alot, ok it is possible my RPM Gauge is off but 300-400 rpm it seem to be big.
I have a Mefi 3 Delphi 1623699 ECM , serial # 866999KA0005247 , Calibration Checksum: CB5A
Do you thing this is the right calibration (454 mag MPI)
Next time i'l try an other RPM gauge.
Any one have acces to mefi 3 ECM (454 mag MPI (385hp) and 454 MPI (310hp)) to check the part # and Checksum calibration # ?
Thank you for your help

Thanks guys, next time i will try the boat whit a different Tach (livorsi or something like that at higher exterior temps.
And if i hit the rev limiter again, i will try a mirage + 25p.
