p12 ecu from prelude increase performance?

[Raukorist77]

i have an offer on a p12 ecu from a 92 prelude and the guy claims that when put into an accord it will
-Increase Horsepower
-increase MPG
-You can go past 120MPH no fuel cut off!

is all this true??? if so is there a thread on installing new ecu's?

[vietkid_2006]

if your car is an EX then it's useless. DX/LX then yes it will.

On a LX/DX it will slightly increase performance. Not sure about mpg though.
But it will definitely not go past 120, that ECU has a top speed governor.
The PT6 ecu on an EX in the other hand doesn't.

I'm running on a P12 ecu by the way.

ok so i have a 92 accord lx and my question is will changing out to this ecu make a big difference/ is it worth the 100 bucks hes asking for it??? and if it does make a difference does anybody have some numbers that would very helpful
thanks guys

definitly not worth 100. if your gonna get one try getting one out of a wrecked prelude. look at junkyards.

[Raukorist77]

alright then thats why i aksed. :P thanks! i think i might look for a PT6 ecu now or p12 how much do you think i should be paying for either of them?

[deevergote]

$45 tops.

PT6 is the stock F22A6 ECU, and is really only good for the F22A6.

The P12 is special because the F22A1 in the Prelude is identical to the F22A1 in the Accord. The intake and exhaust systems may be slightly different, but the majoity of the 10hp gain is in the ECU programming.
It's a more aggressive tune, so chances are, your MPG could actually decrease.


And who cares about the 120mph governor? If you go that fast in a 20 year old car, you're a complete moron.

[shadowdlink]

Well, is it worth $100? Hell no it isn't. That's way too much. I payed $50, and even that was too much.

It doesn't really matter that the P12 has a top speed governor, because really... you will rarely go that fast.
The reason why the P12 is a good bolt on mod for our CB7 LX/DX is as said before. Same engine in the Prelude as our cars, but with a bit more of an aggressive tune.
The PT6 would is a nice mod, but before installing that ECU you'd also need to change the camshaft(to that of an EX), Intake manifold(EX or Prelude h23 IM), and less restrictive headers to get the most out of it because that is what is different from the EX version to a LX/DX. A bit of a hassle to do.
That's why the P12 is popular, its way freaking easy modification on the LX/DXs.

What exactly does the p12 come in so i can look for one?

did you read the above post before you posted?!

it comes from A prelude S F22A1 engine it has 135 Hp.....our Accords with the F22a1 only has 125 the 10 hp is the difference people are talking about though i'm still yet to see dyno results...but its a good performance upgrade plug and play no mods easy to install....the Pt6 thats useless unless you got a F22A6 what engine do you have on your LX?

I did read the whole post. Thanks. I understand its from a Prelude but I didnt know the years I should be looking for. I should have stated the question better. I have the F22A1 in mine

it clearly states 92 Prelude?...lol

[nope]

i think he wants to know what it looks like haha

[ghettoryde]

So it only came in 1992 Preludes?
