I have a Greddy Profec A boost controller and the following message appeared on it last weekend - 'CH' (before starting the car). I switched it off and on and it was ok and the car seemed to run ok (as well as it does at the moment which is poor). Anyway, tried it tonight and it did not give the error message. Does anyone know what CH means as it must have been displayed for a reason.
Cheers, Dave.

Thanks Tim. I do have some instructions from the web but CH was not on them. I think this points to me twiddling with the boost adjustment with the ignition off (even though I don’t remember doing this). At least it means that I have nothing to worry about.
Cheers, Dave
