s13 b13 ecu same?
I have a JWT b13 Ecu. I'm guessing this is a no but can I send it to JWT and have them change it to an S13 ECU? Anyone know?

^^^ that is true, the KA has a distributor. Pretty sure he bought an sr-swapped s13... i could be wrong though

The NA S13 SR (non-turbo RWD SR's use a distributor) and B13 SR ECU's are apparently nearly identical, and the RWD ECU can run the FWD motor and vice versa without a problem. Supposedly one of them has a slightly more aggressive tune, though I have no idea if that is true.

my guess is your asking about the chip and not really the ecu? if that is the case, yes contact JWT they should know.
