Oh I nearly forgot... thanks for the circuit in the first place.

Hi Matt. Just to let you know that I haven't abandonded the PWM Motor Controller circuit. I've been unwell and just havent had the energy to do much. I have though designed the PCB and have all the parts. I will be using the circuit to also control my thermo fan under control from the MS. If you have time, check out my blog http://www.jamesobartlett.com for updated info. Have you progressed at all?

Just want to follow this since I have an A1000 ready for a straight six engine with a turbo and it certainly doesn't need all 1000 for highway driving.

still looking forward to it i haven't got my pump in yet but hope to get it done soon

Any luck recently I'm about to mount my fuel system so...

I'll be testing this Wednesday Oz time. I had to change the design to sit my setup so that and work has got in the way.
I'll post here and on my blog the full details.

Well i finally got to it. Bottom line is after bench testing the prototype, I decided not to go with it, at least not in it's current form. I have found some SSR's that will handle PWM frequencies up to 3500Hz, or so the specs say. Further details on my blog.
