Thread: P13 ECU

  1. #1

    Default P13 ECU

    Okay tore up front carpet today (after finding out honda puts the ecu's by passengers feet (just sayin) and found that I am the proud owner of a p13. I went to NAPA place today and he said it looked like it had been from a junkyard. Well it wasn't even mounted to the floorboard when we pulled it up so I guess so but to my knowledge my fuel cutoff is still set at 6400kish which only seems to happen sometimes? Also I know about the knock sensor but I don't care about that I just want whats going to give me best PERFORMANCE for my engine. Heard of some people doing a h22a basemap on a chipped p28..Is this a better route? What about the p03? Any suggestions? Reviews of others?

    I've got the p28 with a hondata, had to get it tuned though. I wouldn't go with just a chip with a basemap, it wont run as well as it should. Better bet is to get the limiter taken out of the p13, cheaper too.

    The rpm Limiter? Thatd be nice! I found a p28 someone is selling on craigslist with two step but from what I can two step basically just allows you to spin both tires instead of just one tire catching right? Should I get my car tuned since its running the p13? I know a dyno place that I'm almost 100% they at least do remapping. And Im taking the car back to napa tomorrow too, gonna see whats causing a random oil light to flash at cold start but if I turn the car off and restart it the light is instantly gone..not sure what that is because I'm reading good on oil and it still seems nice and thin, not thick and gunky and its also recently been done (as told by previous owner) gonna edit my post about the tranny too. And you don't have to email me the manual now xVeXoRx just whenever you can bro is cool and good lookin out.

    Never heard of anything called two step, the LSD is what makes both tires spin. I would go ahead and change the oil and filter, not saying that will fix your light problem but you don't REALLY know if they changed it. Get it tuned if you can. How many miles are on the motor?

    Yeah I had to google it myself haha. And no I actually raced another honda with a k20 swap tonight light 2 light and had a late jump on him and sat spinning for 2 lengths!! Haha. 90,000 miles on engine. Yeah I'm actually thinking that unless he told the mechanic 5.1 qts that he added 4.1 (4 cycl fill up) but the dipstick read fine. Definitely taking off the rev limiter tomorrow if the shop dyno place can do it. Are there any other upgrades I could get to the chip while im there? or is it pretty limited for the p13?

    Not the rev limiter, I guess its the fuel cut-off at around 110mph, the p13 has one. Theres no point in revving that motor past 7200 rpm it starts to lose hp after that point.

    Really? I had heard that the h22a jdm went to 10k rpm? Also could I pluck your brain about a turbo setup? Bolted my p-13 to the frame so it wont move around now. Did you see a big improvement horsepower and torque after yours was tuned (aka end product compared to before was it worth the money) and how much should I expect for that process minus the ecu craigslist im sure i could track one down

    No, the redline for the jdm h22a is 7300rpm.. Whoever told you that is crazy unless the motor is FULLY built, even then I don't think I would spin it up that high. You go and try and spin it up to 10k rpm and you let me know how that works out for you.. The Hondata S300 runs about $495 and dyno tune time is usually around $150 per hour. Dyno time shouldn't take more than an hour unless you have all kinds of crazy shit done to the motor. The difference I seen between the un-modded p13 I got off eBay and the hondata were not very big maybe 5-10 hp but my h22 is stock just I/H/E and a lighter flywheel.. The biggest difference will be in the gas mileage, I have gotten up to 37mpg on the highway in my civic .
    If you boost, do low boost. The h22a isn't really known for boosting reliably unless built

    Oh yea, I sent you a link to download the manual,, and you don't need a s300 unless you plan on doing a lot to the motor in the future an s200 would prob be fine for you. I've seen s200's on eBay for as low as $270.

    Okay THANK YOU! I have heard the same about the h22a needing to be built up but everywhere I look I do see the 7psi though and I have luckily found a used gst stock turbo with 110,000 miles (give or take) some shaft play of course but it does have a 7psi wastegate spring and I could get a boost controller and he even has some 450cc injectorrs and manifold just not piping but all of it for 50$ I mean am I crazy but it seems like if I was to do a turbo setup it would be good to do some stock turbo which is built for lower build engines *right?* than some insane aftermarket 25 psi wastegated down to a 7psi..AmIright?

    If you really want to boost it I wouldn't do more than like 5psi. I knew a guy a while back who had a h22 in an accord, was boosted at 5 psi. He drove it like that for like 2 years then he bumped the boost up to 6 psi and the engine blew....

    Wow..That kinda sounds like my luck too. Its weird because from what Ive read, heard and deduced (which means could be completely wrong) It seems more like an issue with it 300hp range on the accord/h22a its weird as shit. Think I should get that p28 ecu? Here's the post 4 it.
    I have a chipped p28 ecu for a Honda civic or integra, it has 2 step , 9k rpm rev limiter, and 4500 rpm engagement point has only been used for a few months the price is negotiable.. But remember this ecu cost $210 from phearable.net so don't try to bang me in the head..

    I like the idea of the 4500 engagement and the 9k rev limiter also sparks my intrigue!
    Please tell me what I should do bro! ANYONE!

    Also what about using NOS?? Like a wet system instead of turbo?? Safer?

    There's no point in having the vtec engage at 4500 unless the fuel trim is right it will end up running lean. Mine used to kick in at 4500 but it was tuned with hondata.. As far as boost goes more people spray h22's than boost them. If your just wanting it to run good for now and have a little fun with the car without spending a lot it would just get the speed limiter taken out of that p13 and run with it until you get the money to do it right in the long run it will be worth it and your motor will thank you for it.

    And having the rev limiter at 9k is just plain stupid.. In my opinion

    Maybe I'm too busy thinking big power instead of practical haha. hmm So stay with the p13 and just go get the car tuned up and speed limiter removed and run it like that. I guess the 9k limiter would be pretty dangerous I was just thinking that with that i would be able to stay in vtec through every shift with my lsd gear ratio.
    Bro is there anyway I could get your number? I've got a couple other things going on that I need some assistance with and you've helped me out and saved me at least 150$ on the ecu.
    Thanks a lot for real

    As far as staying in vtec is concerned, go out and drive it. Go through the gears shifting each time at 7300rpm, when you start off in the following gear you WILL be in vtec through all the gears if it kicks in at 5k which it should with the p13. My h22a in my civic has an lsd as well so its the same motor as yours, so I know what it should do.

    i keep throwing a code if im in fourth and really stomp the gas after kinda slow driving. ive read and printed out the instructions for reading the codes on obd1 with the pap3r clip but i cant figure out how im supposed to turn the car off then on to read the code because the c.l goes off once i turn car off even if i instantly start it back. could this be knock sensor or maybe misfire in cyl 4? ideas? can anyone give me some direction on actually checking code

    EDIT: Actually ive went through 2 tanks of 93 premium gas and haven't thrown a code yet and before I was running 87, was it the low octane gas causing the code perhaps?

    Um,,, YES. H22's don't like 87 AT ALL. Your only supposed to run 93 or better.

    I haven't had to worry about checking codes, I can see them with the Hondata on my laptop. I know theres a way. Look in that manual I sent you it's probably in there..

    Oh shit I didn't even know you had sent it! I thought It was still too large to send!! Definitely will comb through it multiple times then. Now...call me crazy but I swear my engagement is at 6200rpms...you said should be 5k? How is mine 1200 k off?? Possibly the accord tach thats still in? Would that explain it?

    Also with a new dist cap, ngk sparks and plugs should I go for a tune up? I feel like the guy I got this from probably didn't have a chance to take it to get it tuned Does it need one? Also ran 4th gear hard (accel decel accel etc) and no code! I added octane boost in (even though its help is minimal) havent pulled a code yet.!

    Tach could be wrong, stock engage point in the p13 is definitely right around 5k unless someone messed with the ecu before you got it. Glad to hear no more codes. You could run some Lucas injector cleaner through it after you empty the tank that has the octane booster in it. Lucas makes good shit.

    Will definitely look at advanced/zone/napa and see where I can find some at. Im doubting the ecu was fooled with but I could also be wrong about that and about the fact it engages around 5k. I had just got home but will run it tonight to check and see where engage point is. Have found someone locally selling some chipped p06's p28s etc so may look into that comes socketed and neptune or cRhrome ready for 150. not a bad deal for real!
    Can you tell me your shift points like say your 2nd gear at 25mph and 3k? I actually have a vid I did when I was just checking out the rev I'll see if i can find and post it as well.

    **Manual Downloaded!! You Da BomB! And it won't let me upload the video maybe I'll email it to you?

    Dude..I am a retard. My engagement is 5200. I just emailed you the video and was like wait why not just watch it and see what it is b/c i'm sure i'll be able to hear it... Damn sure enough I could right at 5200. Still What you think though ;0
