ecu programming

[paradox]

is it possible to have 2 settings for your ecu? For example put the mods on you car to make 325 whp then have another setting to make like 100 whp to improve gas milage on the interstate. I would assume it would limit the air and fuel into the engine so it will still have good a/f ratio but would use less gas and what not. If this is possible which brands and how much, i'm really curious about my mpg since the price has skyrocketed.

It is possible on many Nissan ECU's. You have to get the ECU socketed and buy a chip with twice the memory capability. Then you burn two maps to it and use a little adaptor that has a switch wired to it. Then you just flip the switch to position 1 or 2 to swap maps. Even with the car running. Just in case!

I do not know about other brands of ECU.

Also the new E-Manage ultimate can have (I think) 4 maps stored. It will hook to just about any import and some domestics.

Yeah, but I less than 50 bucks invested and can burn any tune I want. I can burn an optimal higway tune AND keep my foot out of it. But I elect to keep it tuned at full boogie!

well ummm you have the most awsome 240 ever so yea it deserves it. A little more info on what my plans are. After ski season and a summer of working hard to earn enough money to find a wrecked wrx to swap everthing into my 97 obs then use it as a daily driver. but with the occasional trip up north where there are plenty of switchbacks and s's.

I have some fun with my 135 hp but on thoes turns i need more umph to get around the damn truck and slow ppl without taking too big of a chance like i did last w/e.

Yea i'm hoping the ecu i get with my wrx will have at least 2 maps availiable so i dont have to buy one.

Dont know anything about Subbies. Sorry.

Oh and thanks for the props.

I have 5 ECU maps which range from about 50 hp to 500 hp. The are switched with a 5 button remote.

was that pre-programed or was it tuned to your car?

Both actually. It came pre-programmed to my car (Audi S4) but I changed it as my modifications changed.

They actually don't sell the technology I have anymore (IBE) but a newer device called flashloader.

The switching device shown changes between programs.

Thanks.

well i guess that makes more sense. But I see ecu running like from 300 to 1.5k! all i really want is to have 2 maps and have someone tune each for their designated purpose. I have no idea what kind i need for that, does anyone know? I know that this is a big loaded question since there are so many different ecus out there. Its not like the ecu is going to be pushing a ****load of power. Like i dont' know the difference between a stand alone and a piggy back other than that a piggyback uses the pre-existing ecu and the standalone doesn't need it.
