Default Re: Questions on my direct port meth setup

All,

I need your help.

Since I have moved to motec ECU and removed the Aquamist ECU (Motec now controls the pump and FAV).

We have it working no problems but I have a large amount of black soot/smoke under WOT now (I never used to when using stock ECU and Aquamist ECU).

We believe it has to do with the way we setup the FAV through motec.

As I understand it, Richard says if you use motec without the aquamist ECU you must run the following:

PWM to FAV (30Hz, 1.5A drive with 60-75V clipping)


We never did this, we wired the motec directly to FAV and ran it at 70HZ, the pulsing is very fast but we have full control of duty from 0-100%.

Can someone explain why the need for volt clipping with 1.5A drive?

Do you believe this is why we are experiencing the black soot (mist is not fine enough)? We are only running it at 80% duty up top. I run a 50/50 mix.

Thanks
Rob
