i have a cb7 accord witha h22a4 motor......im running off the f22 ecu and need to know if i am better off running the p28 or p13 ecu? the reason why i am asking is cause im running low on money and i do believe the p13 needs the knock sensor for the vtec to work and the p28 doesnt need the knock sensor......my knock sensor is bad and dont really have cash to replace it so should i just run the p28?



also if anyone is good with hooking up the vtec please reply with and usfull help i know nuttin about it and i was wondering sense its a h22a4 will i need to buy a obd1 vtec selinoid or will mine work with the p28 or p13?

 

You do realise you dont have to make a new thread just because your last one is further down the page right??
IIRC the P28 ECU requires chipping to run the H22A which will cost you money....

 

wont the p28 not chipped run the car alot better than the f22 ecu? i cant even barly take off with the ecu i have now....at least the p28 would make it a little better and have vtec till i can get money to chip it?

 

i think it will work non chipped just will run a little lean?

 

P28 ECU is from a Civic right?? (not too sure on the ECU codes)
If it is the civic one I would think it is just as bad as the F22 ECU as it wont have the right maps in it...... it may not even fire into life.
Run a P13 ECU (H22 ECU??) and buy a knock sensor from someone.

 

see im confused cause alot of people are telling me to run a p28 cause u can program them and p13 u cant.....idk i was just trying to get away with not buying a knock sensor cause im broke and dont want my car to sit there and rot away anymore......need this thing up and going....

 

can anyone else give me there opinion on the p28 ecu with a h22 motor? just wanna hear what others have to say about this....

 

will vtec work without knock sensor

 

yo sup i did that swap on a 96 accord wagon but i put an h23a,listen u r better off putting the p13 on because i was running mines at first with a jdm p73 and still it had no power to move the engine. put the p13 and run it like that to u get the sensor. well thats my opinion, the p28 without a basemap is worst than the f22 ecu.

 

Thanks i just got the p13 ecu and im gonna install it in a day or two......Hope its easy to hook up the vtec cause ive never done it....this swap has been a pain in the *** but im thinking its gonna be worth it in the long run......Thanks for the replies.....

 

an OBD1 P13 ECU is about 100 bucks and even without the knock sensor it'll run well enough to get around. The P28 WILL run the car but performance will be SEVERELY hindered. I would get the P13 both ways, because after you use the P13 if you decide to go with a standalone EMS, you can still sell the P13 out for probably as much as you got it for. good luck

 

So i just purchased a p13 and when i plugged it into my car, it ran like crap.....My f22 ecu makes my car run better? Does anyone know why the p13 makes it run like crap, pop and fart, and also wont allow it to take gas? please tell me this is something dumb and easy to fix.......im about to sell the car cause i am getting so angry with it and i really dont wanna do that cause i know with my luck someone will have it ripping with vtec 2 days later.......Any ideas please reply....

 

come on someones gotta know why this p13 is making my car run worse than the stock f22 ecu? could it be the restrictor box, idk much about them?

 

p28 chip ftw

 

i dont wanna run a p28 cause i gotta pay someone to program it from what i hear.......This makes no sense cause the p13 is the stock ecu to a h22, which should run it obviously......can anyone give me ideas on what could be causing this not to take gas and to run like S***? (Wont even idle)

 

i have a p5m which is obd2 and ive searched for the correct jumper harness to run it but cant seem to find on that converts my obd1 harness to use a obd2 ecu? any suggestions on if this is a good idea or where i can get the jumper?

 

what year h22 did the p13 come off of?

 

idk a 92 or something......why would it matter? if its obd1 than its obd1 it shouldnt make a difference what year car it came off from should it?

 

i wish watertown NY didnt suck so much.......seems like im the only person in this whole ghey state that wants to do a swap.......either that or everyone else is just to god damn brain dead to try to help me.......thats why i gotta get on this forum that no body helps you on either.......wish someone from around here that was good at swaps would get ahold of me.......anybody know of someone in NY state that is really good with swaps cause im sick of this thing and want it done asap.....if not this car is getting crushed at the bone yard, cause if i cant enjoy it after all this hard work to put the new motor in then why let someone else enjoy it with the little bit of simple work it need now? Why sell it when someone is gonna spend ten minutes hooking up the vtec cause they know what there doing but wont help me hook it up....

 

yo sup what year is ur car? if ur car is 96 and up u should use a obd2 ecu.

 

not a p13

 

yo i can help u wire up the vtec thats nothing hard its simple just get in contact with me.

 

thats what I was about to say.....

H22a4 is an OBD2 engine buddy. Youre using the wrong ECU. Your running an OBD2 engine with a OBD1 ecu......

 

my car is a obd1 92 accord and yes i am using a obd2 engine, but all sensors and everything have been converted to obd1 and is currently running off a obd1 ecu......im not stupid i know the diffence between obd1 and 2.....its gotta be something stupid.....nicolas where are you located? if someone wants to call me or text me feel free to anytime i really just want anyone opinion/help cause like i said its gotta be something simple and dumb.....315-405-7974

 

just had a really smart guy tell me about the ecu pinouts being differnt one the prelude and the accord......i was wondering if anyone knew the exact pinouts i have to switch on my obd1 accord harness to match a p13 ecu? i just dont wanna go threw them all one at a time and was hoping someone would know the few that need to be switched?
