Can it be tuned to....when the water meth runs out the fuel will richen to the 11;1 ratio....running safe.

Depends on if he has a usable input. If he does you can use a hobbs switch to trigger when the pump is making pressure, this can trigger the input linked to table switching for both fuel and timing... the switched tables are for the meth tune (ve3 ign3) and his standard tables (ve1 ign1) will be used as normal.

There seems to be several outputs that I used to have that I don't have no moe.

When I first built the ecu, and had 2.9xx firmware, both outputs worked that I had set up to control both the fan, and the water pump.

When we upgraded the firmware to whatever version came next, I lost one of the outputs for whatever reason.( spare 7?)
Do you think that firmware upgrade somehow changed how certain programmable outputs had/have to be wired to work?
The LEDs on the end of the ecu seemed to work before as well,..now, like spare 7, no worky either
The one that is just hanging there neither goes high, or low...( it used to trigger 12v) any idea on how to troubleshoot this thing?

Yup use the output test to trigger the different ones untill you get your output.

I think the adc6 adc7 are used for the nitrous outputs in 3.4.2

Well, all I know is that I followed the build instructions to use the IAC outputs for spares( since I have a fidle valve) and of the two sets of the four pins that were dedicated to that output, one was supposed to go high, and the other was supposed to go low the high output dedicated to the fan works,..the other output?.......

Poof!

There are really only two answers:

1. The firmware update did not complete 100% (this is unlikely since it seems to be working?)
2. Their software developers and quality assurance are clown shoes

Either way, I'd send it back to the Chinese hack it came from and have them re-flash and test with the latest firmware or revert it to a version that functions correctly an re-test.

Mike here is the manual to the ms2 with a 3.57 hardware board.

If yours is older I will find the info for your hardware.

My only question on the meth - Is it going to use such an amount that it isnt reasonable? Cost isnt an issue, but are you having to stop and fill up the tank every 50 miles versus every fill up?

Mike when you were looking at catch can breather setups why didn't you look at the setups for 1 bank turbo engines like the all mighty 2JZ in the Supras? Shouldn't that be the same concept? :shrug:

Craig, I haven't found anything specific to any i6 with regard to venting the engine. I'm in virgin territory it seems.

See,..this is how I see it, and where I sit on the fence about the whole water/meth intercooler path over conventional intercooling...

Right now..on a 90 degree day...my IAT shows to be about ambient.. ( as it should, the water in the intercooler will be the same temp) when I stand on it the temps will raise about 20 degrees..and will quickly cool back down to ambient when the IC is running..there's a 3 gallon reservoir full of antifreeze and a Cobra pump, moving water from front to back,...and through a set a fan cooled radiators keeping all of that copacetic.
The point to the above is that even w/o the IC running,.the temps only went from 90 to 110...

If I added a water meth system it'd have a 1 gallon reservoir w/ a low level light when it gets low..id only use it for boost numbers above 7 psi.

Therein lies the beauty of my MSII.....if I can figure this thing out..

The water meth will only be activated at XX pounds of boost...( wherever the engine rattles) let's say that's "8.5 psi"

There should be some programmable output in my MSII that could be tied to that chore..
As a fail safe, when that low level light in the water meth reservoir gets triggered, I should also be able to send an input signal to my MSII that says " Hey! Dumbass! No more high boost" and tells the EBC to back off to a duty cycle that will not allow for more than WG pressure, which will be 7psi.

Now....my question ( to myself) is......

If the water meth only triggers at 8.5 pounds..how long will one gallon last? I mean it's not like I drive around with my foot on the floor all the time in this car..If my IAT's do in fact only rise 20 degrees w/o that IC running,..

Why do I need all of that crazy Mad Scientology?

How much cooler will the IAT go when there is a mist of water meth being sprayed into the engine?
How much longer will the water meth last if I repurpose that 2.5 gal reservoir that's full of antifreeze, and filled it with windshield washer fluid instead?

No way to mount an indicator light in-line?

yes... but then you have to be paying attention...

-MS turns the WMETH system on.
-in line with the nozzle is a hobbs switch, it gets pressure from the pump and turns on.
-the hobbs switch triggers an input to the MS saying "yes we have WMETH spraying"
-MS takes the input and switches from the no meth[safe] tables to the meth tables[aggressive]
-when boost drops off the MS output to the pump shuts off, pump stops hobbs switch looses pressure input shuts off tables switch back.....

done this way you are setup in a failsafe....

use the grounded output from the MS that triggers the pump as the feed to the hobbs switch, it in turn is used as the input to the MS. done this way if the output never fires the input cannot be triggered raising the timing and leaning the fuel.

This winter, I'm gonna pull the MS out from under my dash, and just get stupid building the programmable outputs for the above scenario and others..it's amazing that a kit, purchased for under 400 bucks will let you do so much.
I intend to exploit all of the possibilities.
