okay..i have an '05 sti. i got an intake, dp, and cat back, and a turbo manifold... im not satisfied anymore...so im planning on putting on a better turbo, fuel system and a front mount....will a reflash be okay, or will i need a stand alone...or one of those laptop tuning systems???? im kinda a beginner here...thanks

 

by the way...im from maui...and we have no awd dynos here...will this be a problem???

 

You'll probably want to run something that can be tuned elsewhere and sent to you. Someone like Vishnu or Gruppe-S can reflash your ECU via ECUtek and send it back to you. Another option would be the Cobb Accessport. You can download maps from Cobb or other users that match your mods. Gruppe-S and dbTuned, among others, sell the Cobb system.

The ideal thing would be a custom tune, but without access to a dyno, you'll have to stick with maps made for cars similar to yours.

You could also go with something like the UTEC if you are confident in your own tunign abilities. With a laptop you can adjust anything you want. However, systems like this aren't for beginners.

But to answer your original question, a reflash or Accessport type system will do fine. You won't need a satnd alone EM system.

 

I have a reflash on my car . It runs fine . A very noticeable power difference . I put my aps fmic , aps cai , and tbe before up-grading my ecu and ran into alot of problems . Boost spikes and alot of back-firing . If you upgrade more parts on your car do the reflash at the same time .

 

Get cobb tuner software/access port, wide ban 02 sensor ,egt gauge. Put the sensor in the top of you down pipe about 3-4 inches behind the turbo ( like the cobb down pipe), mount the egt gauge on the driver side of the header right in the little button (you will see the button whene you take off the header) learn how to tune your car and tune it on the road.

Admittedly I make this sound simple but it is not very hard at all.
