I got a Gtech pro ss for christmas, and i cant seem to correctley caliburate the rpm, anyone have this problem?

 

what is that is it like an aeroforce?

 

g meter (accalerometer)

 

anyone?

 

i had a gtech SS for about a day. it blew sack. theres something in our electrical systems that prevent it from reading our rpm accurately. i got it fairly close but it still liked to jump around a lil. i cant remember what number worked best on the rpm setting. and for the shift lights you have to set them 300-500 rpm lower than what you actually want them to go off because it cant keep up with our revs.

 

really? anyone elese try it on the cobalt?
