you need to get a DOHC ecu...just get one from 4th gen lude (OBD-I i assume)..ditch that EBAY ecu...spoon never made **** for the 78-03 accords, nor for any preludes...the just recently started running a k24 powered TSX for endurance races....so spoon didnt touch your ecu....

jcronal

Wish I would have known this before purchasing it. are those ecu garbage. If you had to decide stock ecu from accord or ebay **** which is better.

i20ar

this sux... so you guys think it his ecu? it sounds very logical... 94 accords are obd1?

think of it like this...the accord ecu is like a brain for the accord engine (f22)...when you swap the engine out for an h22, you need an h22 brain (obd1 p13 ecu) to control the h22 motor so that everything on the h22 motor functions correctly...unfortunately, people on ebay create "spoon" and "mugen" ecu's for accords and preludes that just run like crap...you really have no idea what the ecu was tuned for or how it was tuned all together...most of them lose the rev limiter though (which i would not suggest doing) and also **** with the timing and air/fuel ratios, thus creating a motor that gets shitty gas milleage and is potentially dangerous...but since you don't know any of the details of the chip that was installed in the ecu, you never know what you are getting...anyways, it sounds like you need to take your car to a professional performance honda mechanic that is familiar with h22 accord swaps so that he can diagnose the problem more directly...it's hard to diagnose problems like this online since we can rarely get the entire story on what has and has not been done since you are in the dark on what all your mechanic has and has not swapped in or out...

Get the p13 and take that car to someone who has done this before, and i mean someone who did it right, before you really do some damage, just looking out for the fellow honda-tekers!

You DEFINITELY need the h22 p13 ecu. Find a stock one from a junkyard or performance site. Don't buy that Ebay crap again....as its been said, Spoon and Mugen don't touch those. Do you honestly think that you could buy a Spoon/Mugen ECU for $75 or whatever you bought it for? Doubt it.
Anyways, since you have a SOHC ECU, it isn't going to work on a DOHC motor....things just won't work right. Plus, you have the whole VTEC issue. I am going to make a guess here and say that your mechanic buddy didn't run VTEC lines either. Word of advice, take it to someone who knows what they are doing. And also, give us the name of the shop this guy works at so I know NEVER to head there! Any mechanic who tells you that SOHC and DOHC are the same thing and their ECUs are interchangeable, is an idiot.

the stock accord ecu is not staying in the car for long. Im a not saying that the accord ecu is the same as the h22 ecu. it has been a month Im still lookin for a h22 prelude p13 obd1 ecu. I will be burning the ebay ecu. The car run good no problems becide the oil light comming on. The only difference is that I have no vtec. I need the proper ecu so that the vtec works. I changed that cheap oil to castrol syntec. All the ground on car were rechecked and tighten. so far no oil light.

Damne I guess I got jerked cause I paid $194.00 with shipping and handling.

This is what the ebay auction said.

You are bidding on a OBD1 P13 Spoon spec ECU, this ECU was taking out of a 95 PRELUDE with a JDM H22 swap. VTEC kick in @5000rpm to 8000rpm. this ECU was chip by a professional. Not only it change in the REV limiter But also air/fuel ratio and SPEED limiter. this ECU will learn how to run it best on every performance parts you put on your car to maximize Horse Power. The ecu will help you gain up about 20 hp @ the wheel or even more if more works done to your engine. This Spoon ECU will works on any manual 0Bd1 vehicle 92-95 Prelude/Accord. 96 up will need a wire jumper conversion harness.

When I did my H22 6 years ago (still running strong by the way) I used my F22 ecu for almost a year before I found a stock H22 ecu for a reasonably price. The F22 ecu should run your h22 motor fine it will just feel like a regular accord motor. When you look for your ecu look for an american one not JDM because the JDM has a speed govern of 112 mph. I know this cuz my first h22 ecu was a JDM.

I've used a chiped ECU that came out of a GSR. I didn't really notice the difference in power. The only problem with it was it didnt want to idle. The chip in the ecu that you bought from Ebay is probably for a B-Series motor. It can potentially mess up your motor. Dont throw it away though because you can still sell it to someone that wants to use it for say a hondata setup or something.

VTEC needs oil to opperate correctly, maybe thats why the oil light comes on, i might be wrong tho just a thought..but never the less everyone else is right you need the right ECU and make sure someone hooks everything up right

Yeah, I've heard this, but my JDM P13 has a governor set to 120mph.

Wouldn't that be nice, if your ECU could learn to run its best. Think about it; no more dyno tuning.

there actually is a small learning curve to most ecu's...it's not a whole lot, but it does make minor corrections based on the way you drive...

Matgallis

Don't you also need to re-wire for vtec??

jcronal

Well it has been two days since the oil light does not come on when the car is moving. But i did notice today that when I park my car my rpm dropped below 800 rev. The car feels like its going to shut off the oil light blinks. the rpm imidietly pick up to 1000. I tried parking the car again and it did the same thing as soon as I hit the clutch and put in reverse.

quick gixxer

OMG V-TECK...... well good luck fixing the problem, i hope it all works out. An h22 with vtec in an accord is berry fun indeed

Are you sure you weren't listening to lil Jon? You know that your car doesn't like him.

jcronal

Is $250.00 reasonable price for a h22 ecu. and what is a usdm h22 ecu is that american. also the ecu says it came from japan out off a b-b1 what is that. this ecu is a p13.

fastwanabe

jcronal.. couple thing.

1. You will need an unmolested P-13 like everybody said.
2. Your idle dropping could be caused by quite a few things, like wrong ecu, air trapped in your coolant system or the IACV needs a good cleaning.
3. About your oil light, have you checked the oil level? you could be low on oil considering H22 are notorious for burning oil. A bad oil pump could also be the culprit. You need to solve this ASAP.
4. Learn to spell and start sentences with capitol letters.

jbonehead85

the ecu can def. be the prob. the fuel maps and ignition timing is diff from the accord to the prelude. Be careful which p13 you get soem of them have immobilizers which prevent you from using it in a different car. make sure vtec i swired correctly.

jcronal

its been about 3 weeks since the oil pressure switch was changed. The oil light has stopped flashing. The problem was that oil pressure switch. The car is still running good with the f22 ecu. V-teck will be connected this weekend.

Was the wire harness done correctly? If you had an EX you already had VTEC, if not there was another mod you needed to add to the harness. I had a professional mechanic do my work and we both decided to send my harness to Hasport to make sure it was right. $300 later it was as sweet and clean as a new H22. By the way, you can get lucky on Ebay if you know what you're doing. I got my P13 off a guy parting out his Prelude for about $160 if I remember correctly. I was told by many not to use the F22 ecu very long or puch the car very hard until I put the P13 in.

Stoich EG2

$20 says it still won't "hit V-teck". I bet you still don't have the right ECU and still don't know how to hook up "V-teck". show me where on your car it says "V-teck" by the way, hahaha. there is more than the VTEC wire you need to hook up, there's the knock sensor and the secondary intake runner wires you need to have as well. you dont HAVE TO have the secondary intake runners but it'd be nice to have some low end torque.

jcronal

It was that stupid oil pressure switch all along. Changed the switch and it has been about a months and everything is running well. Listen Advan06 you gonna owe me twenty. When I said I need the v-tec connected I know it not only one wire. I have to add wiring for Knock sensor, air intake bypass, vtec selenoid, and the EGR selenoid valve wire and the O2 sensor heater wire have to be switch. By the way Im not doing the connections it the same mechanic that every one said to stay away from. Im going to use the ebay ecu since i cant get a hold of a stck h22 ecu and will replace it as soon as I can find a stock h22 ecu.
