rb25 with rb20 ecu

[usererror]

i got my series 1 rb25 running on both ecus(rb25/20) the rb20 ecu i have has nistune board. now i read i have to send it back to nistune to have it loaded for the tps voltage. can i send the the ecu with board still solder in the ecu? will reprogramming the the rb20 nistune board cost me anything?

Depends who you send it to. I only ask return postage covered if sending here. We prefer just the board pushed into anti static foam (or if missing that then stryofoam coated with foil) and packaged in an anti-static bag and bubble wrapped well to avoid any damage to the board

Board is lighter than sending the whole ECU so will be cheaper both ways for freight. Just be careful (lift side to side) when removing the board from the ECU
