Hi guys,
I'm currently finishing up some odds and ends on my nissan sr20 swapped e30. It runs a link ecu and Ive wired one of its AUX outputs to power the factory economy gauge on the cluster. I can get it to perform a full gauge sweep but unfortunately cant get it to stop at specific values throught the range. For Eg I force 10% duty cycle at 50hz with hopes that it would stop at say 20MPG but the gauge just maxes out at every Duty Cycle value i input . The long term plan is to setup a boost/econo gauge so i can get it to reference manifold pressure and move the gauge accordingly.
(Im not interested in that EconoBoost product)
If i can determine what frequency the gauge runs at, I can then establish the duty cycle to move the gauge to the value I'm after.
Unfortunately I just dont know what the factory ECU sends to the cluster as ive pulled that motor out already so cant test it.
If anyone has any advice or is savy with a multi meter and can determine the frequency / duty cycle the ecu sends it signal to the gauge that would be much appreciated
