    I have a p30 ecu in my ls integra which gives me the capability to rev higher but on stock cams i think my power kinda drops off at 6900 or so but the little higher rev gets me into the next gear with a better rpm, how far do you think i can go safetly. 7500 or less, whats your opinion.

    stock red line is 7200 on the ls ecu.

    man I wouldn't even rev it up to redline. after 6900 you aren't making any more power anyways so if you shift at 6900 yeah you will be at a lower rpm but you will be back in the powerband for the next gear. So you will be still gaining power. Even if you are racing someone on a mile long course, if it is a drag race chances are the extra 300 rpms versus being in the powerband will hurt your times rather than help them. so shift at 6900. and just punch it.

    Ialso just got a light weight flywheel and six puck cluth which is way overkill but it should rev faster now so i shouldnt hve to wind it out that far for the next gear cause i will be able to get through the powerband alot faster.

    yeah it will rev faster but remember the reduced mass of the flywheel somewhat also lessens the shortcut of a powershift, using the heavier flywheel's mass to kick the car forward a little more.

    but i love my lightweight flywheel, it's more fun. and straight lines arn't my thing.

    So wait...you're running a P30 ECU with an LS engine? Is that correct?

    EDIT: I read your other thread (the one that got locked) and got my answer.

    Why the hell are you running a B16 ECU on an LS?

    Is your LS a B16?

    No.

    Does it have VTEC?

    No.

    Is it built to rev as high as a B16?

    No.

    So why the hell would it benefit from a B16 ECU?

    It wouldn't (in case you were wondering).

    Stop listening to your buddy, he's an idiot. The only reason to use a different ECU is that you plan on having it chipped and tuned to run your specific engine setup. Otherwise, there's no point to it. It won't give you any performance gains, and you're just going to end up with constant CELs...

    I was gonna ask why also, but I read in the other thread and I believe he said he thought it ran better with the P30 so it wasn't worth an argument.

    Have you ever done it before, a p30 in an ls. Well i have and you can feel the difference so unless you have done this before there is no argument you have no first hand proof to prove me wrong.

    Whatever you say, I'm not getting into an argument. There is no need to be using the wrong ECU.

    Alright then moving on, im looking into launch control right now, what exactly would i need. i looked on hondata and it said I can use s200 but i need a modidfied stock ecu, and then i looked at msd but its confusing. It think i need this soft touch thing but im not sure and then im also not sure if i need the other products that plug into that. What are your suggestions for launch control.

    hondata s300 ftw.

    your wasting hardware features by using a P30. those are rare. sell it and buy a P28 or something else and chip it. you realize the difference you feel is due to the fuel maps and ignition settings being ment for a B16. it's probably running lean with too much ignition advance.

    get the hondata, get a proper tune for your motor, and it'll all be good. it also has launch control. i have it. it's lame. unless your lazy as fuck or have no skill launching, it's just not that necessary that i would spend lots of money to impliment it.

    You can run a p30 on an LS. It will run a little bit on the fat side though and you should get a cel from it. I personally wouldn't do this, just because I know better. :) As far as spinning it past its oem redline, its pointless. No power and risk of damaging the engine.

    You're an idiot. Period.

    The "difference" you feel is your car running lean with the timing too far advanced, because your ECU is trying to run your 1.8 liter engine like it's a high-revving 1.6 liter. It's similar to those crap E-Bay "performance" chips that mess with your fuel and timing. Yeah, you might feel a bit of a difference, but at the same time, you could very well be fucking up your motor.

    Honda ECUs aren't magical, you can't just throw one from a higher-performance engine into your car and expect it to perform like that engine. The correct solution is to use the computer that came with your engine and augment it with a piggyback device, or chip an ECU and have it custom-tuned to your engine setup.

    But whatever man, I'm just an idiot. You obviously know what you're doing. You keep on revving that P30-equipped LS past it's redline and see what happens...

    I'm checking out of this thread...it makes my head hurt...

    As far as it running lean on the p30, it would actually run slightly richer. The timing would also be affected, not sure +/-. I can only assume there will be more timing due to the vtec camshafts they control.

    Piggybacks = :thumbsdown: Not a fan. ECU tuning prefferred.

    You are very right. I'm sorry, I was thinking rich and typed lean by mistake, my bad...

    And I'm with you on the piggyback thing as well. I was just trying to lay out the "correct" tuning options as opposed to just throwing a different ECU at a motor and hoping it improves performance...

    yeah, honda is not a domestic V8 that by tuning you somehow discover 20 horses.... lol, i love watching that happen.

    precision engineering is the key term
