hi all i am tring to do a relative compression check on a 1994 v8 landrover disco
i cannot seem to get the proper wave as sample pico settings.. can anyyone advise how to get proper readings? tried various different settings, but to close a wave- form to evaluate cranking amps per cylinder
regards j..and does anyone know the air flow voltage for same car at idle it is near 2 volts hc are at 3000 ppm and only come down when cruising was towed in for non start i adjusted air gap at dist (low reading for pick up) got car going! but i suspect air flow meter..playing with my pico so i want the relative comp settings..dont think its a cylinder prob but i want to be sure! any help regards j..
