anybody has experience with any one of those? what do you think about them?

i like blitz power meter id cause it can display mph (but it got no rpm display).

i like RSM cause it got rpm and g force graph (but only can display info in km/h)

any meter out there that can combine the 2? or maybe display oil temp/pressure also?

 

Ok i've been looking into these two items myself and here are my questions.

Do these hook up to the ecu or ecu lines....i.e. rpm....speedo wires. our are these like the g-tech and are accelerometers which need a flat surface and seem to be a pain to calibrate.

curious here! thanks!

 

i think you need to tap into the ECU lines with the connection

i kinda looked at the apexi user/installation instruction and that's the impression that i have.
