Does anyone have an idea of how many have the MS system and how many would be interested. As pointed out Im working on details and I hope to have them this week. If it turns out to not be compatible there is a chance we can develop one to work with it.
Also, once I post this data it would be great if someone local (Atlanta) can come to the shop (preferably before the city of Atlanta and metro area runs out of water in the next 80 days causing a massive catastrophic disaster that will make Katrina look like a trip to the candy store) Anyway, aside from my bantering, any ideas?
Also, can someone educate me a little on the Megasquirt system?

Thousands of people have MS ecu's. I can not comment on how many would purchase a HSV from you guys, but there is definately a hole in the market for a reasonably priced HSV. Your market isn't necessarily limited to MS either; there's tons of people with advanced piggy and standalone ecus that need such a solution.
I'm up by Road Atlanta, and willing to bring my vehicle to your facility in Norcross, especially if there will be some sort of consideration in terms of product
<edit> I am also willing to dyno the car to show before and after results.

Ok, sorry for the delay. Here is the deal.
The minimum HZ to run our valve would be 400. its been tested as high as 12,000 HZ. The higher the HZ the better. If your at 800 HZ on the ms, that would work well.
If your at 250 or 300 hz I cant guarantee. Our valve is not an "on/off" valve that you see in alot of the older designs and some of the ones still used today. Ours averages the on time/off time giving a very nice flow response and exceptional repeatability. At 250 or 300 hz, the valve cant open/close fast enough and you will get some pulsation. The higher the frequency the better the results. 800 hz is going to be beautiful.
Thats all I need. I would like to see who wants to drive down my shop with the MS system and lets test it. Maybe we should do this before the total water ban

MS has 2 different WI outputs
1 output goes to ground when all 3 trigger points are met (RPM, MAP, IAT).
The other output activates when the 3 trigger points are met and pulses ground at the same rate as fuel injector channel 2.

If it's fast enough to drive a fuel injector, I'd think it's fast enough to drive yoru HSV too. Though that is an assumption on my part based on total ignorance.

The fuel injector is not as fast as our valve. But like I said 800 hertz will be very nice.
When do you want to stop by? Program a simple map to work off of RPM or TPS make a trigger of either of those with PWM so we can test the valve. My info tells me its going to work beautiful, but until we do a test I cant say for sure.
If you dont have time to stop by, I will be glad to to sell one to anyone that wants to try it. If it doesn't work, just return it for a refund.

A quick reference:
"PWM Frequency (Hz) (PWM_step): This is the PWM frequency in Hertz (cycles per second) used for the PWM Idle valve, when it is enabled. The PWM frequency can only be adjusted in steps of 80 Hertz, from 80 Hz to 800 Hz. "
http://www.megasquirt.info/megatune.htm
Should work, based on my brief readings. Anyone want to try it out, let us know.

No--I'm busy using my idle valve for.... idle
I'll get with you re: testing it out on the WI output. But I have to get the hardware mods done first.
