Really thinking of getting my ecu tuned but wanting to know how it affects fuel mileage in the car. I drive about 40 miles a day or maybe more so dont want to kill my fuel mileage.

What tune are you running?

What is your average fuel mileage?

What percentage of city and highway driving are you doing?

What psi are you running?

 

30 freeway
17 around town
5 with the foot in it.
18psi

 

Right about what I'm getting on iPd's stage I tune.

 

spot on since thats what I am running too.

So you are running the tune in the above link, that costs $695? Also, did you upgrade your exhaust? If so, what exhaust system?

I like the idea of getting better mileage. I am getting 25-26 on highway and about 18-19 in town. "96 Turbo with 162,000 on clock. Not heavy footed around town. Only when I do road trips to the beach to pass cars on the road.

 

Oh by the way I forgot to ask, which one you did?
850 T5 1994-1995072222/275236/2809.7/14.57.4/6.286072$695.00850 T5R628240/275236/28012/14.57.0/6.286628$695.00850 T5 1996-97072222/275236/2809.7/14.57.4/6.286073$695.00850 R 1996-97628240/275236/28012/14.57.0/6.286629$695.00850 GLT* 1997936190/230212/2658/127.8/6.686936$695.00

 

Yeah, I'm running the tune in your link, 850 R 1996-97 (Stage I) with a cat-less 3" Downpipe and a TME/iPd exhaust.

Boxpin's other mods are in his sig.
