ECU Help

[kronikally420]

Hello, I have recently come to learn that you can modify your ECU to change your ignition timing advance curve.

I would like to know how to do this, or who can do this for me.

(If its a how-to, at what rate should I advance my timing?)


I test drove a f22 and I'm almost positive that is all the guy did to it was programmed the ecu.

It revved surprisingly quick pulled hard and gave him no issues. He moved or I would just ask him.

Thanks

93 EX f22a6 AT ofc

No your just feeling the amazing f22! but you can have your ecu chipped and have things changed through the chipping process..BUT that is not something you can/should mess with, leave it to the professionals

Sounds more like he had a light weight flywheel.

After doing some reading around on here, it seems there are a few chippable computers we can get for our car from various Civics/Integras. However, I also found a few older threads by a member named MRX that said there were very little gains to be had on a stock F22. Apparently they are pretty well tuned from the factory.

Changing the timing a little will only move the powerband around (You'll make peak power at a different point in the curve.) Changing it aq lot can cause the car to not run, or worse. THere are a few ECUs you can tune( or have tuned) but it's not child's play. You can do serious damage to the engine if you screw it up. Look through the big kid sections, you can read posts there, but nor reply. You should be able to find more answers than you'll get in the beginner section.

The stock F22A ECUs (PT3 and PT6) aren't really common ECUs to modify. The amount of control you have is limited, and the amount of support is even moreso. Most people that modify ECUs for use with the F22A use a Civic's P06. Properly modified, these ECUs will give you tuning control similar to the basic functions of a full expensive standalone unit.

I agree with LlamaGoblin. If it revved quickly, it was very likely a lightweight flywheel. The ECU is not something that people usually touch as a beginner modification. It also won't change how fast the motor revs (the ECU, that is... the flywheel will)


If you want to adjust ignition timing, you can do so with your distributor and a timing light.

Say I want to try to get some gain from advancing the timing, and using 93 octane gas...

How do I tell how much is too much? Bind the motor and listen for a ping/labor?


What is the weakest link on a f22a6 auto? (On the same note, how much boost could be applied stock drivetrain and be daily driven+dependable?) 8.8:1 and the high flow head=cheap boosting..? (ya ya...sohc...) I figure ppl will bold the 'auto' but other then that? I ran a f22a1 for 175k miles no problems and it has over 330k miles still running to this day...I ran it hard too

edit: wont the ecu change the rate of revving by changing the advance of the ignition firing curve allowing for faster simultaneous explosions? ideally anyhow

[deevergote]

Revving is simply how fast the motor turns. Technically, a motor that makes more power would probably rev faster... but no ECU tuning or timing advance is going to make enough of a difference in power to make this noticeable.

The F22A's distributor can only advance or retard so much. You really won't gain all that much from advancing and running higher octane. I have been told (never been willing to try it) that you can advance to the maximum amount physically allowed by the distributor and it will not damage the engine.

As you mentioned, the automatic transmission is probably the weakest point. Not that they are weak, but most CB7 automatics have not been properly maintained (most did not receive Honda fluid changes every 15-30k for their entire lifespan...) If you boost an automatic, the transmission is most likely to give out first. Additionally, tuning for an automatic is more difficult. Most of the ECU tuners on here won't even do it.
With any turbo motor, tuning is key. It must be tuned well, or it won't last.

thanks alot...

latest kill with my old f22a1 was a dodge daytona truck ...supposed to have a hemi with 375 ponies or something...


like my car stock, very very reliable

im sure id love it built

edit: my f22a6 is currently out of ignition time...im poor right now and no timing light...i guess i could do it by ear

[deevergote]

Do it right. Find someone to loan you a timing light if you can't afford the $40 for the tool.

you can also buy a socket and a chip for a little of nothing the only thing is its gonna delete your speed gov but it will advance your timeing curve and it will raise your rve line you can buy the chip for like 30 bucks its not a bad deal just time consuming to put in me and my buddy chipped my ecu in like 30 min in his basement i bought a spoon chip and socket it worked great the only thing i dint like was the change in the rpm it was to much but you should maybe check in that you just have to watch your rpm's so you dont over rev

DO NOT use generic chips. They may, and probably will, do serious damage to your engine. This is some of the worst advice ever.

[lownslow]

thats what i did and i did do good no lie the only thing that sucked was it changed my rpm rev to high. you say it will do damage to your engine? how? i would like to know so if its a bad idea than i wont buy anymore.

[deevergote]

It's a fuel curve not designed for your engine. It will cause it to run either rich or lean... an excess of either (lean especially) will do serious damage to your engine. You should NEVER tamper with your ECU if you don't know what you're doing... and you should never install a chip that hasn't been programmed for your particular motor.

And for the record, Spoon never made anything for the F22A. That program was probably written by some hack highschool kid in his basement, looking to make a quick buck.

ok i understand what you mean. and for the record it wont for a f22a mine was for a h22a4 i was just telling what kind i had bought.

[deevergote]

Ah, ok. If it was a genuine Spoon chip for the H22A (which DO exist...) then it may have been good. Though I believe Spoon only modified entire ECUs, and sealed them so any tampering would be evident... so the chip you got is still probably a hack.

The only modified ECUs that should ever even be considered would be authentic ECUs from reputable tuning houses such as Mugen and Spoon.
