Well it works im happy that i have working rpm gauge and retained the coolant low buzzer which for a track car is essential.
cant really put my finger on anything i done and got lucky....cleaned all boards with soft brass bush to remove corrosion on solder joints....any joint looking manky re-soldered and board then cleaned with electrical cleaner.
vr1 pot on rpm gauge adjusts gauge and lots i mean lots of put in and take out trimmimh pot to get in sync with apexi...and i mean lots and its finicky...
pot on odometer blue 1 calibrates it ive literally just trimmed it back a bit need to go out with satnav and see where it is.
on the drawings ive marked the tacho signal wire and tried as 1 forum post suggests direct wiring these...this did not work...just sent everthing screwy which does not make sense ...i tried all combination and still screwy... with all 3 connected and signals and polarity check all buzzers going off and rpm gauge having an eppyfit.
complete pita tbh....so mix n match got a working set....but oil pressure gauge does not work as with the new odometer that should control the boost gauge heyho got the defi gauges anyway.
Dax, allow some time and take some patience pils....
