Removing rev limiter....

Well fellas im getting VVL antsy, and I want to start buying several parts for the car and someday ill go with a EMS Standalone like Rob & Manny, but I would like to know any other options.

The platform would be a 2002 G20 Sport, and as you guys know it houses the roller rocker SR20DE which only revs to about 6800RPM maximum which would suck with VVL as the power of the second cam activating would be shortlived. Im thinking of using an SAFC II in the meantime for fuel management.

Is there any module from Japan or anywhere that would be able to remove or alter the RPM redline? I dont want to swap harnesses (time consuming) and im not going with a JWT ECU, for that id rather go standalone. The Greddy E-manage Ultimate I hear has a new feature where you can alter the rev limiter but it costs $600 plus extras so its not worth it (rather get the standalone). Inputs anyone? There has to be something out there for $200-$300 that can raise the RPM....or so I hope.

Or can the limiter be removed altogether, I would just have to becareful when to shift.

Any help appreciated, Thanks!

Kev

Not sure why you're so against the JWT, but if they do an ECU for the P11, just get it.

Because it requires me to:

1. Buy an older ECU
2. Get it reprogrammed
3. Wire in a new harness from an older vehicle
4. PITA to do.

Its not cost effective IMO when I could have a fully tuned vehicle with a Standalone for a little more of all the things I just posted, labor alone would be a PITA and I sure as hell am not messing with wires.

Get a Calum ECU then sell your existing one.

Why not pay someone to build you a wire harness adapter? Then you could just buy an older ecu and tune it yourself or get the JWT.

why not wait a bit longer and get the standalone? i mean, if youre going to upgrade to one anyway, why spend the money now? kinda sounds to me like youre cheaping out on the engine management..which is one thing you never want to cheap out on with ANY kind of setup

hell, worse comes to worse, use your stock ecu and play a bit with it with the safc till you save up, if youre that hell bent on going ve before you even have the right parts.

You have a point, but see I wouldnt really be cheaping out, I can get an SAFC on the street for cheap, and sell it ASAP within a day or two for the price I bought it for, my question was just very simple regarding a rev limiter removal product. I just want to drop a VVL motor in and tune it with the safc without worrying about my stock ECU's 6800RPM limit. The motor is going in ANYWAY which is why I asked the question, how do I NOT have the right parts? Theres guys down here making great power just with the SAFC alone, is that not a right part?

Domiken, if your swapping in a VVL motor, the harness is 95% out of the car anyways. The easiest way to pull a motor is to take the harness out from the interior of the car and leave everything attatched on the motor and then disconect it when its completely out of the car anyways.

It wouldnt be too hard to swap out harnesses and use a Calum ECU at that point.

Domiken, is there a large difference between the 98/99 SE-L & p11 Sport ECU's main harness?...

If you would rather put a stand alone in, and deal with the issues it creates, vs moving 3 or 4 wires to use a '95 - '97 ECU, then go for it big boy.

Tell you the truth, im not quite sure, but im sure there is. Even between a 99' P11 G20 (all non roller rocker) compared to 00'-02' its quite different.

Its mostly discussed in the contributors section here on the sr20 forum (calum ecu)

I think you can find it in the sr20forum store as well.

well not to burst your bubble, but thats quite frankly the easiest and cheapest route possible for us 00+ RR powered peeps. 150-250 to have somebody make you the harness adapter, depending on what parts you have/can locate/or wanna use of your own. then get a b13 or b14 ecu 50-100 which ever one you'd rather use, and bam, higher rev limiter. however, theres lots of talk about how this works in theory, but nobody has actually documented it.

^^ not true. there have been several people both p11 and b15 (se) that have either repinned, or had a harness made/spliced. it does work, it's just the fact that most people don't want to pay for harnesses, then someone to splice it, then cost for the computer, plus likelyhood of dyno/tuning time. ur nearly talking as much as a standalone after it's all said and done.

i was going to go with the coalitionse-l harness, but some lady crushed the SE, so now i'm looking for a 200sx with the insurance check
