I have a friend of mine who is having electrical issues with his 04 RXP and before he buys a new ecu he wants to try one to see if this is the problem. If anyone can help let me know. It would be best if the ecu had a matching key so it didn't need a program. If someone has one for sale he migh be interested as well. He's computer illiterate. If you can help i'll have him deal directly with you via phone. We're located in Maryland.
