Additional comments back from Marc.

1) Dwell, as you know, is time to charge.

2) Overcharging results in blown coils

3) Undercharging results in weak spark

Thats my point, I was wondering if you may have known the threshold for the stock coils.

concerning the MSII and crank sensor, why did a tooth have to be cut? I was reading on AEM EMS and wondered if their solution of an external trigger wheel might help:

Has there been any progress figuring this out? Banshee's gonna sell me his that he never even touched after getting and is going with a turbo 2.5 now! LOL Just want to see where anyone else has gotten anywhere figuring a straight setup or not having problems witht he whole possitioning sensors and such.

I can help set it up for you if you ever go down that road. The MS is supposed to have come a long way and I may be interested in dabbling with it. Just going to need the connectors to make up a jumper harness

Yeah I could shoot it down to you as soon as I get it in my hands. I'd love to get the Hydra but with my Impreza still not moving I can't let meself dump that much on the SVX at a time yet.

Has anyone heard of the DIYPNP? I'm trying to read over what all it can do now, but theyre saying this one (http://www.diyautotune.com/catalog/d...kit-p-384.html) is a direct plug in replacement to the stock SVX ECU, and its only 400 bucks.

Here's info about it http://www.diyautotune.com/diypnp/index.html

TomsSVX · #38 01-03-2010, 04:47 PM

yes it should work, it has the right connectors... Making the harness is not easy but doable

Tom

STeeL25T · #39 01-03-2010, 05:09 PM

What needs to be done?

TomsSVX · #40 01-03-2010, 05:12 PM

you will need to wire it. Match the inputs to the MS w/ the outputs from the car harness.

Tom

STeeL25T · #41 01-03-2010, 05:24 PM

That sounds reasonable, does this cut the wheel missing a tooth thingy out of the equation that was holding this back before or is that still needed?

TomsSVX · #42 01-03-2010, 05:39 PM

I do not know for sure. I would need to read some about the system to see if they have made it possible for the secondary input for a marker trigger.

You still interested in my shooting mine down to pay you to do up the harness and then get to play around with it and get a feel for it?

You should run a 60-2 trigger wheel for the crank signal for the MS.

I had the MS running on the EG33 in the 962 chassis before I pulled the plug on that drivetrain option and stuck the motor in my WRX. I sold the MS setup I had in between the downtime to a guy building an aircraft, but somewhere I still have all the files for the programming I had done. Would have to do some digging to find them though.

The PNP solution would work but as Tom says you would have to correlate the MS inputs to the stock wiring harness. Not hard, especially if you just build a conversion link harness. Pending the condition of the engine harness on your car it bay be better to just build your own complete harness(use a dummy SVX harness for clips and plugs). Personal choice really. I had made an entire harness for the car but that was an easier option at the time.

And I prefer the MS surface mount stuff. Buy V3.57 with 64 bit. Really good stuff. Some guys have just recently released dual VR control for it so it can now be adapted to previously unavailable motors like quad rotor wankels(R26b) with alot of spark going on.

Sure I will mess around with it but make no promises on making it work 100% I am more or less just interested
