reversed pwm idle setting,

Post by E30stroker »

if i switch the setting to reversed , does it affect the test mode options,
in test mode 0 is open 100 is closed, and it test out mechanically that way also: 75 percnt is 3/4 closed more air flow than 100%
if i toggle settings reversed/normal, in idle control. it does not affect what direction the valve opperate in test mode, is what ive noticed,

running the motor at idle , pwm idle duty % , guage on -tuner studio dash ,- reads 100%, and may reach 93%,
but it just stays in one state, does not oscillate even though the engine is running way to rich and stalling out, and oscillating on its own
possibly due to afr correction,

the other settings in ts would also never closse the valve, so im wondering what it STAYS at 100% during low,rich idle and not adjust at all to correct?

Test mode kind of lives outside the normal operating code. So unless there is a reverse in test mode screen I strongly doubt anything in the normal operating settings could effect test mode.

okthats good to know, here is my msq
im going to take a data log pretty soon here to log its settings,
ran it this morning and most of the setting were similar, and the valve gauge showed 100% and doesnt move,

The ford valve I have been using has an operational range. Too little DC it does not regulate and too much DC it does not regulate. Have you tried to run yours in warmup mode? That is how I confirmed the operation and figured out the operational range of my valve using the idle warmup duty table with the engine running.

and still hunts at idle when i open it all the way at like 2 percent
