ECU Swapping

[Akord10thaniv]

I was just wondering if there are any noticible benefits from swapping ECUS, and if there are any negative effects....Does it increase horse, torque, timing, shift points(I have an Automatic), does it change a/f ratios? What is the deal and is it worth doin?

cool man, thanks bro, I sure as hell don't got that much work into the A1, and I doubt that I'll put that much into it, I'd rather look good than go fast around here....Roads blow here and there would be no where to go that fast so investing that much in the motor would be a waste, but thanks for the info

on the f22, you'll notice some gains IF you have a lot of mods that warrant the changing of air fuel ratios......but you wouldn't notice anything from the ECU with just basic bolt ons....with a cam, headwork, exhaust, intake, header, and possibly higher compression, then it might get you a few horsepower....as far as the shift points, there is an ECM that controls the auto tranny, and i THINK that you'd have to alter it instead of the main ECU...not sure though...another option would be a higher stall torque converter and a shift kit installed in the tranny...that wouldn't be cheap and would cost more than a manual swap though

I totally agree here.
In my H22a swap I have the p72 (gs-r ecu) JUN chipped, and I like it, bc she can take higher revvs at the track, on the street, wherever, bc there is no rev limiter. I like it better than stock.

The P72 USDM GS-R ECU is the only other ECU that can run the H22A besides the P28/P30.

The Benefit about running the P72 is you no longer have to deal with the EGR circut and it controls the IAB.

The downside with that ECU is that even with chipped programs they still don't show any power gains over the P13 on the Dyno.

The JUN program that is tuned for the P72 is tuned to run with Jun Brand Toda Cams package, Has a Vtec engagement of 4400 RPM, and a Redline of 9100 RPM. You probably never rev it that high that's why you beleive it has no rev limiter.

I personally wouldn't run that program though. Since it's in no way tuned to run the H22A there are probably many places in the power band that you are running the engine lean. Not to mention that when it comes to the Dyno you actually lose power even though it "feels" faster.

lol we already had about 7 posts going back and fourth on this before the database was deleted. When they reloaded it I guess they used the last back-up which didn't have all of our latestest posts.

I have an F22a6 ecu on my F22a1. I tonssssssss of mods done to my car. I noticed a nice bump in power at 4000 rpm, and a few extra HP at 5500rpm to redline. No big gains, just a few HP.

I have an F22a6 intake manifold on my car, but i took off the top half, and bolted on a plenium/throttlebody off of a H23/H22. Also have an F22a6 camshaft installed, and lots of other stuff

Eh, I responded to this, but I think it got cutt off cuz the site died soon after I posted it.

Anyhow, the F22A6 has a different camshaft than the A1 or A4? I'm assuming so, cuz you mentioned installing one over your A1.

Also, fast93accord, you receive my PM?

[fast93accord]

The F22a6 camshaft has more lift and duration on the intake lobes only.

I tried replying to your PM's but it keeps saying your mailbox is full.

thx Fizzbob, I figured that out already cuz I knew my inbox was clean....thought the sent shit would automatically clean itself every so many days... shouldn't it be setup like that?
