I have never done that and have no plans to. thanks :)

CMT, where's my spec sheet bro?

I will post it as soon as I have it.

Finally, they committed your ass. :eek5:

I am not a inpatient but i am waiting rather huffily for these results.

Aye, you have at least 1 sale here if it's compatable with the MS

Savington 10-20-2007 11:06 PM

If this will work somewhat easily with MS, I will order one in the spring.

cmtech1 10-21-2007 09:20 PM

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?

Ben 10-21-2007 09:25 PM

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.

magnamx-5 10-22-2007 06:28 AM

If it isn't stupid hard to install i can do the same testing up in KY. I run WI as a standalone so if this works i might possibly ditch my 2 stage and go with a single stage on a bigger nozzle controlled by this.

I am interested in this valve if it is compatible with MS.

cmtech1 10-22-2007 01:30 PM

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.
http://megasquirt.sourceforge.net/extra/waterinj.html

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.

cmtech1 10-22-2007 03:07 PM

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.

Are you taking that 800 Hz from my Hydra Nemesis comment?

cmtech1 10-22-2007 04:16 PM

probably, LOL.

anyone know what the MS runs at?

CM

magnamx-5 10-22-2007 04:19 PM

I haven't found that one yet i am sure Jerry or mat at DIY autotune know but they haven't poped in.

cmtech1 10-22-2007 05:40 PM

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.

CM

Ben 10-22-2007 05:42 PM

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.

cmtech1 10-22-2007 05:57 PM

Well was just a quick search.

anyone that wants to try it out, call us so we can can sort this out.
