Yes, they program your actual ecu. Buy a spare incase its your daily driver.CapoDiTuttiCapi said:Do you have to send your actual ECU, or is there a core charge? Don't know about you, but I can't be without my car for 2-6 months waiting for them to send me my ECU.

RollcageSR20 said:When I ordered a JWT ECU (S3/S4 cam program) back in 2000, I was charged the price of the ECU plus a core charge. I received the ECU, amazingly, during the same week. I shipped them my stock ECU and received my core refund the following week.
I bought a JWT ECU (standard POP program) for my (former) NX through SR20DEvelopment. If you want to hear my story, send me a PM. It's not as bad as other stories posted about them, but it is just as shady.Toolapcfan said:I think sr20development sells JWT ECU's and you only send your core to them after you get a reprogrammed one. Good idea, but considering their reputation, I wouldn't give them $.01.
