Very little support for our cars unfortunately - primarily because the gains are so little, in comparison with our boosted cousins.

So i have to spend 1500 bucks if i want my tuner to dyno tune my legacy?

You don't have to spend $1500 to do a dyno run, but if you want a tunable ECU, yes.

Yeah, i was referring to dyno tuning. Thanks for the help. Is it really necessary to get a tune after installing full exhuast and simple bolt on's on the 2.2?

[Airgne]

no.

a dyno tune will cost $100hr.. plus rent of a dyno.. the only tune you really need for a n/a is a a/f and/or timing controler at most

so pretty much just go out and get yourself a AFC from Apexi and there is your handheld tuner!

are the N/A ECU's self learning to adjust for bolt on mods, such as CIA, Exhaust etc..? ive always thought that if you did bolt ons such as a CAI that the ecu would still dump the same amount of fuel or does it compensate for the increase in air flow?

I just installed a CIA and noticed a loss in Torque and was thinking it was over fuel'd/under fueld cause its kinda sluggish off the line now.

it will learn some.. but it can compansate truely for the change.. ^ some CIA can have negitive affects. the way they are designed can lower proformance in close to stock engine because they can cause turbulance in the intake.. causing a/f issue most times is it adds to much fuel..

How do i correct this problem or can i? do i need to do some ECU tuning?

[decke48]

the problem usally can be fix with putting a free'er flowing exhaust

and which i cant find for my wagon... nuts!

or does anyone know where i can get one?

[Huffer]

The NA ecu's are self-learning/correcting. the SAFC type controllers don't work so well.

Rallitek's Power Perfect ECU is the only one I've heard of with any kind of tuning success.

[03LegacyWgn]

does that work for all OBDII ECU's or is it specifically for the 05+ LGT's?

[decke48]

any app. but requires some wiring with your harness unless you can find a your specific cars harness extender so you dont have to tap in to the cars harness so it can be easy removed if wanted.
