rising rev limits
Good day guys . How can I rise the rev limiter from 6500 to 7500 for my turbo 99 ?
I sow this thing in ebay.com
RL-1 Rev Limit Controller for Greddy E-manage Blue
The saler sayes that it can rise it but I dont know if it's work on my turbo 99

You need to add fuel past the factory fuel cut at 6500rpm. You can do this with the e-manage blue. You can find this info on this forum.
Of course HD valve springs and a 3.5 oil pump would be ideal.
The Ultimate can do it, but not smoothly.

My engine is built up probrley
I have rev up oil pump and JWT valve springs from a long time. But Im still searching for a way to rise up the RPM .

^^^ Dandy Max's Emanage Ultimate install write-up.
It talks about raising rev-limits with modified injector delay maps.
hope it helps.

I forgot to say that I have JWT cams also . but my problem is the turbo . I have turbonatics . it spools at 4500 RPM . so my power is limited between 4500 RPM to 6800 as a stock cut of .
this is my dyno chart at 4psi

as you can see the HP is still going up until the cut of . so if I have my car tuned to 7300 or 7400 I will have the full advanteges of my turbo because it spools too late .so I will have more power .

The VQ30 bottom end is stout, rod bolts do not have to be changed unlike the VQ35. We had somebody just for ***** and giggles revving to 8000rpm stock bottom end but i seriously would not recommend that.
If all this has already been addressed your best bet for a smooth raised limiter is a JWT ECU. An EU will do it but its not a very fluid way of raising the limiter. Dynos have shown a massive drop off in power right where the stock limiter is than it climbs back up, nobody has been able to solve that problem except switching ECUs.

I think with this setup I can rise my RPM up to 7500 safely .
The last thing I would do is having JWT ECU . Because it will fit in my max . If I have to switch to JWT I have to get US maxima harness . And that is impossible to find it here in the middle east .

unless something has changed/been updated/been discovered in the last few years, you cannot go beyond the stock rev limit with emanage blue.
if i recall correctly this is because you cannot control pulse width directly with EB, only by percentage up to either 50% or 100% (it's been a long time since I looked into it, but this is what I remember.) At the stock rev limit fuel cut, IPW goes so low that increasing it even by 50% or 100% does not come anywhere close to providing enough fuel to have useful RPM above the stock limit.

Its just installing the 1.49 firmware, and seriously no, if you are thinking using an emanage blue/gold to raise the limiter, not a good idea, get an Emanage ultimate, you already spent all that money building the motor dont cheap out on tuning it.

OK thats for 4cylenders engine . how to do it on V6 engine ?
I spent more than 7 years, buying and rebuiding so I lost all my money on it .
so I cant buy the ultimate . I found a used one in ebay but I lost the piding .
Just keep searching you will find one. There is no real cheap&easy way to extend the limiter honestly. My car needs its limiter bumped up to 7000rpm and i have an emanage but oh i dont trust that thing to take over that process.
is e85 available by where you at? is this a daily? maybe you should just put good gas in it and crank up the boost with the limiter as is. plenty power to be made without that added risk.
