First, I do have an extra harness, PM me you snail mail address and I'll send it to you.I hear a lot of different MPG results from this swap, I heard 70s 90s with A/C on and regen at the same time and 100 mpg!
Is that all from just swapping out the US ECU to a Lean Burn JDM ECU system?
I mean what does these CVT Japaneses cars get in their country as far as MPG, sounds like as much as the MT cars do?
It's seems like the way to go if it actaully works as some have posted it does =)
Second there are a number of pin changes on the ECU as detailed in this thread or another one on this conversion.
Third the harness hook-up is the easiest part with no modifications.
Forth, you should expect to get no better mileage than a MT model if that good. It is no magic bullet, it just adds lean burn. Some on this forum have become adept at staying in lean burn for hours at freeway speeds. It takes a lot of practice.
