the only danger with removing your ECU every night is eventually you will wear out the connections. But it will take years to do this.

the bad idle... it depends on which chip, what's in it and if it idled good with the original ECU.

 

yea it idled fine wit my stock ecu i bought it from phearable.net a p28 ecu other than the idling its awesome but i just wanted to know wat it was

 

BUMP!!! I have the same goddamn problem!

have you asked john what the prob. is?

 

i had the same problem when i had my new chip ecu.
my idle will go up and down when the car was cold.
