This thread is for the mostly stockish f22 guys looking for some performance gain from using a chipped ecu. I've gotten plenty of inquiries about getting the map, sending out an ecu with the map, how its going to run, why the map is taking so long and i wanted to clear alot of things up and concentrate you guys into one thread and tell you the absolute truth.
First, I cannot modify the stock pt3 or pt6 ecu's you need a civic or integra ecu. The stock f22 has 8.8:1 compression. This is extremely low for an n/a car but honda made it that way so we could run 87 octane and get away with it without detonating. For this reason and mainly this reason the f22 can't gain much power at all through ecu tuning of any sort. I was able to gain about 5-6whp and 10-12wtq from around 2200-2800rpm but that was it. The rest of the powerband was the exact same as stock or 1 whp less and no amount of ignition timing i tried nor a/f changes made a difference.
The motor just doesn't respond to ecu tuning because of the low compression. The compression practically nullifies any potential gains. So to the ppl with just intake, header, exhaust, pullies, spark upgrades, basically stockish, an ecu is practically worthless for power IMO. And frankly you guys are too bandwagon right now. Theres only one stockish f22 person i know of thats wants an ecu from me but is willing to learn to tune it themselves. The rest of the guys expect perfection from the ecu and will be sorely disappointed otherwise. I can't guarantee it will run flawlessly, i haven't even seen most of your cars let alone know how to tune the engine around your environment. Everything from your driving habits to your elevation come into play when i send these ecu's out. So this is why i'm so hesitant to send these things out to most of you. Because i know for a fact that the majority don't care to know about the ecu at all or tuning.
However, if you plan to raise the compression, change the peak torque from a cam or cam gear, get a good port and polish, or want to go for forced induction and need to add bigger injectors at the same time then the ecu is very beneficial. It gives you adjustability that can't happpen with the stock ecu. You can make the tune as safe or as dangerous as you want to.
Now for a little trip into tuning land. At peak torque, usually at about 3800-4000rpm on the f22's, is where u need the most fuel. You can change that peak torque by simply adding a camshaft. The cam shifts the powerband (namely the torque line) and moves it into the higher rpms normally. If peak torque is now at, say 4900rpm then the stock ecu will still be dumping its highest amount of fuel at the 4000rpm range and you'd be running lean at 4900rpm where you actually needed the fuel. Since the stock ecu isn't adjustable this is where the craze over chipped ecu's came from.
So as far as power goes on a stockish f22 there will be little to benefit. The programs for the ecu's however can extend the rev limiter to whereever you want it, remove the speed limiter, and they set you up for the future of your intended setup as it progresses.
Suppose u have an f22, decide to get a chipped ecu anyways and come across a good deal on an h22. The chipped ecu can be modified to control the h22 and its vtec. It sets you up for your future setup as i was saying. It doesn't necessarily add power it controls it. But of course in some cases there will be a gain but it depends on the setup.
The reason alot of the h22 ppl can get good gains and results is because of their higher compression. Honda also made the h22's p13 ecu conservative to prevent stupidity like filling up with 87 octane instead of the 92 or 93 it was intended to run on. They try to make these cars stupid proof ya know? And that leaves room for ppl to take advantage and get some good gains from an ecu.
Also, the reason i haven't finished this map is because i don't have a stockish f22 anymore. I have to meet up with Grumpys93 when our schedules match up, so i'm not on my own time and theres not much i can do about that. I'd also like to say that with gas prices nowadays its almost essential to know how to tune the fuel curves if your gas mileage falls. I'd hate to send out an ecu and have everything working great except bad gas mileage and have that person not know how to tune it out.
If you have any tuning questions there are two stickies i made at the top of this performance section that will tell you just about everything you need to know.
chipped ecu thread ( yes its long)
Tuning thread (yes thats long too)

If you take the time to read through u will be able to decide if these ecu's are for you or not. You should have some knowledge on how to tune and if you don't...read the stickies. If you have any questions after reading then by all means ask away. I only get tired of answering the same questions as i've answered 1000 times as would any one of you. It'd be like someone coming into this thread and asking " so is it worth it?" I'd go ape shit and i think i have the right to after typing all this lol.
In conclusion, for stockish f22's your only benefits would be:
- a little gain from 2200-2800rpm
- removed speed limiter
- full throttle launch if you want it
- extended rev limiter if you want it (a blown motor is your fault not mine
)
- Plenty of adjustibility for future setups you might build or look into
- If your willing to work with me i'll teach you everything you need to know.
Disadvantages:
- It may not run as perfect as u might think such as bad gas mileage as stated above
- you will need a chip burner to be able to change anything on the map
- you will need to have to have some insight on how to tune from reading up
- possible loss of hp above 3000rpm by 1-2hp
- if you aren't willing to take the time to learn i'm not willing to take the time to help you
Thank you for reading, if you have any questions please ask but please try not to make me repeat myself too much.
