Thread: Picked up a JWT ECU for my B14, any way to tell what tune it has on it?

got a JWT ECU today and was wondering if there is any way to tell what tune it has without calling them, it shows a higher revv limit and bigger injectors but wondering if it was tuned for anything else

call ben pila at jwt and ask

They usually write a code on the chip inside the ECU. If you call JWT with that info, they should be able to help.

ya, i ended up calling them, but this code is rediculously hard to read, so now i gotta scan it and just send in the scanned image and they are gonna try and see if they can read it any better.

Yea -- I had to do the same thing. They don't write so clearly. They'll figure it out.
