What gains do you get from different ECUs?

[bhksk8r]

For the f22a6, WHICH ecu would benefit best? What gains would I actually see with a different ecu?

What all do ECUs do? Change fuel/air ratio and what else?

Thanks guys

There the brain of the car and putting the wrong ECU in the car would only hurt performance....A6 ECU Has no speed limmiter wich is the most noticable difference

Oh okay, thanks man. I wasn't sure if you would actually see some hp gains immediately just from putting in a differently tuned ecu..

[93accordfreak]

If you buy a tuneable Ecu with controls for the butterflies, and have access to a dyno and a good tuner you will see gains but $$$.

The P12 swap on A1's and A4's is a 10HP gain, but that's a different story...

for the f22a6, the stock pt6 is the best ECU. You really don't need to change until you start some serious internal work, or go boosted.

good info! thanks alot man, preciate it

what's an ecu?

so if i can put a A6 ECU in my car every thing will b the same it just wont have a speed limiter?

You might run a little richer. The A6 has a slightly wilder cam, so the ECU has a different fuel curve. You don't need to remove the speed limiter anyway. How often do you get your car over 115 mph? You won't do it at the track until you've done some serious building, and it really isn't meant to run at those speeds. You'll want some suspension upgrades and better tires before you do.

I get everything about the a6 ecu but whats the deal with chipped civc ecu and other models ecu etc.? are they interchangable like that do any of them have an advantage

a chipped ecu (the accord ones arent chippable so we use civic ecus) make it so they can be programmed. basically a blank slate. when you chip them they arent civic ecus anymore. you need to tune them for your car. the benefit is in the tuning not the ecu itself (though some have different features built in). if you arent running a few important mods, like a cam at least, then tuning wont get you much. some, but not much. often not worth the cost unless you can get it done cheap or do it yourself. dyno tuning a chipped ecu is the only way to really make power

[pikey_cb7]

So a a6 computer will run rich and have no speed limitor

what year can i get this ECU out of any cb7 with a a6 under the hood and what ECU code am i looking for on it

[Jonas]

pt6 is the ecu code. any 92-93 ex has it. the 91 and 93 se have it too.

it wont do much for you if you dont have the other a6 parts. the cam and intake manifold are the most significant.
