okay.... here it is: 2001 LS1 Z28 w/ Turbo 350 3 Speed Trans, Hughes 4500 stall (tightened up so not so loose), Ford 9 Inch w/ 4.11s, 28 inch tall tires, Cammed.

I have had the M6 flash put on the Computer so that the codes are not thrown looking for the trans that is no longer there. The speedo is right now, the 28 " tall tires and gears are correct. My problem is that the guy that tunes my car cannot seem to find why I am banging the rev limiter at or around 6200rpm. I can see it hit it in the street and saw it happen on the dyno. He is stumped. I know that he adjusted my rev limiter up to over 7,000 to account for stall slippage and still the same thing REV limt is changed in the primary and back up tables.

Do any of you have ANY ideas on what could be causing this? It has got to be in the computer somewhere!!

ANY leads you guys can give?

t t t for me guys....


someone, anyone? maybe the fact that my Misfire code was deleted and still misfiring etc causing it to go into a "safe" mode?

ttt for you.

i adjusted my revlimiter for my car and i sitll bang at 6200. but this is with hptuners

 

ok, so under engine, idle + Limiters you have

ETC Limit 7000, all the By Gears at 7000 (not sure if it makes a diff in an M6 .bin though)
All the By Temp at 7000
and the Delay at 0 from about 80* up?

May also want to try the Bad VSS at 7000 ... though if your speedo works this probably doesn't matter

if you want send me your .ls1 file to Mike@horist.com ... I *think* I can read it... but not 100% sure (I have edit v 1.3 but forget what years it works for)

ok in an 01
you have By Gear, By Temp and ETC Limit by Gear, make sure they're all 7000 ...

Another thing to consider... the PCM won't know what gear you're in right? so it may think you're in park/neutral all the time? if that's the case change the park/neutral rev limiter too

 

Is the 6200, what you see on the scanner or what you
see on the tach? The tach is notoriously slow....

 

I will double check the park/neutral rev limiter as the car does think I am in park all the time so she will start (the car is flashed as an M6 though and not sure if this matters?). As for the tach being "slow". I agree, but it is cutting out on the dyno as well consistently way to early. I have been hitting rev limit and just eyeballing it it was low 6000s. On the dyno 3 times, it banged at 5900, 6200, & 6200.

Thanks for the input
