auto ecu reprogramming

[crioten]

are the ecu reprogrammers worth buying for a s13 auto? has anyone ever used them, and what exactly do they improve?

another question is, they cost about $300, so are they reuseable, what i mean is, can joe schmo use it on his car, then sell it to me for $50 and i use it on my car?

thanks

maybe if u give us a picture/description including brand name and what exactly the "ECU REPROGRAMMERS" ur talking about are.... we could give u an answer that might help, im assuming ur talking about something like venom or something..... well i believe they re-program based on ur mods, like exhaust intake and such, so it may not be re-useable
