The Map is not mine to sell, Mate of mine does the tuning for a reasonable price either way See my sig for details for The Speed Lab
As for the ECU, it is plug in and the car will probably start and idle but it wont be driveable thats for sure (rb20 has smaller injectors) so your best bet would be to leave the 33 ecu in there and drive to the tuner. Or get the 32 ecu epromed, buy chip from TSL and plug it in and drive it, Would be best to get it on a dyno to check everything before you really drive it hard tho.
As for price, ECU cost me 50 and the mapping/dyno time averages around 300-400 including chip install
