Consider me an interested GE8 user.
I do have a question.....
How far apart are the GE8 and CR-Z ECUs externally? So, let's say that I could just plug in a CR-Z box in place of my GE8 box.... Although unnecessarily costly, it could be an option of the pinouts are close & the ECU wouldn't complain about the lack of whatever IMA bits & pieces.
They use different pinouts for a few things. You could build an adapter harness (I did), but it would be a lot of work.
I tried this with a Civic Si ECU on my GE8, since it was most similar according to someone I emailed with at Hondata. It wouldn't work, it didn't interface properly with the immobilizer, MCU, or the console. I eventually gave up and settled with the car I bought, selling off the ECU and the harness I built. A few months later I bought a CR-Z, and was glad I didn't have a lot of extra money into the Fit.
There's really no market for a GE8 flashpro outside of a couple of the fit forums. Then out of that, there is maybe a hundred users who would actually buy it.
But as a CR-Z owner, I'm happy that I can buy one for my car. :D
