just want to know how much of a difference you get with gas mileage using an aftermarket ECU, in this case, the technosquare.

 

No difference when I drive normally. But if I'm pushing it a lot, 2-3 mpg less.

Isn't this thread the same as your thread below from 3 weeks ago?

haha, i forgot about that..

 

First of all, an aftermarket ECU makes no difference in closed-loop mode so your around-town MPG won't be affected. And at WOT it should actually save you some gas since it's tuned to run more lean. The reason your MPG will probably suffer is because you'll want to go WOT more often.

 

 

I meant the aftermarket ECU will save you gas when you compare WOT gas mileage stock with WOT gas mileage with the aftermarket ECU.
