Hondata

I recently purchased a hondata s100b system and sent my p08 ecu to a licensed hondata dealer to have the system installed, to make a long story short i got shafted by the dealer and im in need of a new ecu. A friend has a hondata 4b prepped p30 ecu, i was wondering if i could just swap my s100 module and eprom into the ecu? i havent had a chance to compare internals. thanks in advance for any input.

Yes. The only thing to check is that J12 is removed from the ECU for the s100.
