Yes it works on our cars. Dig deep in both emanage ultimate threads and you'll read on how to set it up.

New news to me.... Learned something new today... Out for the hunt... Was just about to chip my ECU too...

Here is where the info on the increase rev limiter is at:

yup, the EMU can raise the limiter. I currently rev mine to 9K (my car has a lot of work done to it 'though. wouldn't reccomend revving stock valvetrain that high.)

[DarkHeroKOTRAJ]

I have 3SX stage 3 heads they should be good till 8500-9000 correct?

[Racer_X]

I would think so. Just make sure your car is still making power at those RPMs. spinning high RPM's can make for a whole new batch of problems (Intake manifold design, Turbo selection, oil temp, oil weight, engine balance, lifter stability, and oil pump capability all play important roles). last thing you want is to screw up your motor at 9K while not making any power due to Intake manifold harmonics or lack of turbo capacity or floating a lifter or running oil too thick or too thin to lubricate the rods properly, breaking down the oil or busting an oil pump gear. If your car is built for it, The EMU can get you there, but be careful!

i got stock heads and bottom end but im not looking for more then 7800 or 8000 max.. im alittle confused by your steps in the emanage thread.... i don't understand the 2 columns HOLD, LIMIT...

thanks Adam

hold is the column where you want the EMU to take complete control over your Injector output (beginning). Limit is the column where you want the Emanage to cut the fuel (Maximum RPM rev limit...New). The stock ecu starts pulsing injectors completely (off and on) at 7300 That keeps you from going beyond 7300 from teh factory. It actually cuts fuel in two stages. At 7175 or somewhere right before 7200the ECU pulses fuel supply in half Normal duty cycle, 50% of normal). This is supposed to slow your R's up so you don't zoom beyond the 7300 limit. The ecu makes the pulses at around every 60mS. When you put the Time value in the EMU, that value is what it want's to see. i am not exactly sure why they set it up that way, but that's how it works.

Would you mind posting up your Rev Limiters Cut settings? Thanks,

sure. right now I am non turbo, so I only have vaccuum values. Oh, apprently I was off on my wait time values. I have 1.5 mS in my values for that. My memory isn't the best at times I guess :-P (that's why figuring out values yourself is always best ). here you go:

Hold = 7000 Limit = 9000 ; Values are Relative Pressure (PSI);

PSI/7000/9000
-11.0/4.5/4.5
-8.0/11/13
-5.1/17.5/21.5
-2.1/24.0/32.5
0.7/30.5/39.5
3.6/32.5/42.5
6.6 through 33 psi are incomplete

Fuel cut T.P. is 10%
Wait time is 1.5 mS

This is for my car with DR heads, Race cams, short runner intake and PTE880 (850 cc) injectors

Here is another one that I did for an SL with a turbo kit and 550 cc injectors and stock SL heads. These values were run up to 15 psi. anything past that I didn't test. :

Hold = 7000 Limit = 8000 ; Values are Relative Pressure (PSI);

PSI/7000/9000
-10.0/20/22
-7.6/25/27
-5.3/30/32
-2.9/35/37
-0.6/40/42.5
1.6/45/47.5
4.0/50/53
6.3/55/58
8.6/60.5/63
11.0/66/68
13.3/70.5/73
15.6/75.5/78
18.0/80/83
20.3/85/88
22.6/90/93
25.0/95/98


Fuel cut T.P. is 10%
Wait time is 1.5 mS


These values should be used just as examples. If you put these exact values in your car, there is a 95% chance that it won't work right. This just shows you how it shoudl be formatted. but the wait time number can be used for any 3000GT/stealth as that and the hold Rev will be consistent.
