Personally, I don't think pulsing a big assed solenoid is a good practice. Nitrous systems have been using that practice for years now, and there are a lot of bad reviews to their detriment. The solenoids get hot, current draw changes as a result, impedance changes and things cook.
Just open the solenoid when you want the water to flow, and shut the thing when you want it to stop.

Well im doing it to set the flow amount by rpm, I bought a solenoid from prometh that is meant for that application to be pulsed at 25hz for up to 20mins. So this should not happen again.

Yeah but you think your circuit failed And burned up a transistor.
The very first time I cooked a circuit trying to do something that resulted in the stuff that keeps my engine out of detonation to stop flowing would be the last time I test out that theory.

I use it to keep temps down, the car is not tuned on the meth. the meth is just another safety cushion.... when the temps start to come up [and they do] I have it set to start pulling timing in scads.

In my case it's both. I'll be content to just opening and closing the thing.

The only thing I'd change is triggering the thing at a higher throttle percentage ( possibly a higher boost # too) to keep it from dumping a buttload of water into the engine when all I'm trying to do is get on the interstate. I thought I added a variable, and included TPS percentage into the circuit equation, ( and maybe I did) but my engine gets into boost w/o any throttle it seems.

I depend on the stuff.

dont worry when you do the MS3 upgrade there is a whole section in there just for Wmeth injection so we can set a whole bunch of parameters.

I got alot done this morning, I fixed the leaky power steering pump, hooked the windshield spray nozzle up so that works now, and found 1.5 free pounds of boost!!

The power steering pump was easy it just needed one of the O rings replaced that seal the pressure control valve to the plastic reservoir, that took all of 10 mins to complete.
I decided after doing some reading to place a w/meth nozzle in the rubber coupler before the throttle body, 7gph nozzle was what i had on hand so that went in. This one i just setup to spray full on when the pump was spraying. The first pull I could see my normal 9.6 PSI then it slowly climbed up to 11.3 psi. I thought WTF is going on at first, so i did another pull and the same thing happened. The water is helping to seal the rotors and now i am happy to say i got a free 1.5psi out of the deal.

Sorry I didn't quite get that...

For the benefit of those of us not in tune with the same interstellar network as you, please explain...
Meh.......I can’t say that I even know what the hell happened there.

No problem, I wish i could have gotten away with just changing the connectors to ev6 by crimping on new terminals and building each connector. Some of my injectors need the extra length in the harness so splicing on a pre-made pigtail made the most sense.
I have no idea how many pins need to be moved on the extension harness yet so i will try and document that as well as i can for you.

As a temporary measure while you build a new harness from scratch? :D

so after doing some more research i have decided to increase the size of the nozzle in the intake before the blower. I will increase it from a 7gph to a 10gph nozzle, once i have the pulse solenoid from prometh working i will attempt to build a closed loop style table for the PWM control of the solenoid that will control the flow to the nozzle post blower. This way i can have both spray when the intake is heat soaked to quickly lower the intake temps then have the post blower nozzle reduce its flow as the temps come down.
This will take quite a bit of experimentation to get right i believe.
Just my kind of thing

Well I have a problem.... The AC does not cycle anymore, i jumpered the cycling switch out and it came right on.... I will need to have gauges put on it to tell more.

The heater hoses are leaking somewhere.... i can see the chalky white water marks in a few spots, almost seems like it is leaking and traveling down the hose. I didnt have much time to look at it today so i will address it when i have more time. Its not missing much coolant so it has to be a small leak. Also going to change the oil here soon and see if the filter has any more big ass metal flakes in it.

I hope there's no more metal in your oil. Man, I really thought I screwed my car up over the weekend. Ended up being one of my cheap spark plug wires.

Check around your ac fittings for oily residue. Check the condenser too. Seems like you may have a small freon leak.

Whatever is set up as a safety with my MS works. Felt like I hit a brick wall. Power dropped out but came right back. I must've hit the rev limit spinning tires.
