Hi guys, I've spent the last couple of days researching on google to find the info I need, with no luck. I've tried searching on this forum too but can't seem to find the basics. Well, I did find some stuff on Subarus and Mitsubishis, but I'm not sure that will help me.
Ok, let me explain my situation. I have a 2004 Renault Clio 1.5 dCi (common rail turbo diesel) and I would like to learn how to edit the ECU myself to improve performance (or upload a pre-tuned map if possible). I don't want to buy one of those expensive tuning boxes or pay £250+ for a remap. I would like to be able to map my friend's vehicles later on if I gained enough knowledge.
What I need to know is:-
• Can I tune the ECU via the OBD II port? I read somewhere that you can only reset error codes via the OBD port?
• Would I need a specific Renault cable, or does a universal cable exist?
• Does all software work with all cables/vehicles? Or again would I need specific Renault tuning software?
• Are there such websites around that offer pre-tuned maps for download?
I'm just looking for a starting point really, and so far I seem to be going around in circles. How do the professional tuners do this stuff?
I would really appreciate it if you could throw some tips this way to get me started, or perhaps let me know of somewhere I could get some.
Thanks in advance,
Chris
