i had my ecu chipped a few months ago and now its playing up, i've still got the standard chip but i'm a bit worried about taking the ecu apart and putting the standard one back in.

could anyone talk me through refitting the standard chip.
Thanks for any help..

Why not take it back and get it sorted?

I'm not 100% sure its the ecu causing the problem so i wanted to check before i went moaning to the people that fitted it.
