Before you even ask yes i am installing a turbo on stock 07 fit with 337k miles. Why because i like to party, oh and already have a spare engine to replace this one with! But any how just really wanting give this little turd a bit more pep in its step without a motor swap, i bought the car dirt cheap and love boosted vehicles. My main questions are what engine management options do i have, keep in mind ive been around since the days of using FMU on boosted tegs then graduated to crome, then to hondata once i grew up, lol. But i am not finding a lot of info on the Gen 1 fits as far as ECU/programmer options other than that HKS piggyback system that came out like 10 years ago. Any help is much appreciated

 

Hondata makes a Flashpro for 07-08 Fit . Youd be silly to use anything else IMHO.

Hondata FlashPro is the only good solution. As you probably know from using them, piggyback systems are like bandaids.

I just got a FlashPro for mine, but haven't had a chance to play with it much other than loading their canned tunes. One of the canned tunes is for a Greddy kit at 10psi with 450cc injectors. You could probably use that tune as a baseline once you change the injectors to what ever you are running.

Out of curiosity, what are you doing for an exhaust manifold, downpipe, etc?
