Just wondering if anyone here has tried doing a water/meth. injection and controlling it with utec ? I would like to do my install this weekend. I have a snow performance stage 2 pump, stage 2 nozzle, and a variable solenoid (not the variable controller that comes in the stage 2 kit) . Any help would be greatly appreciated.

 

Anyone try this yet ?

 

There is already a great thead on this subject

 

Yes, we tried it. The UTEC has a spare solenoid, that can easily control something like nitrous or WI. You can set it with several "And" conditions. IE: Above 4000rpm, AND 5-psi, AND 75% TPS.....for instance. Also has an "off" window setting.

 

Did you guys wire up the pump so it was always on even though the solenoid is closed at low boost levels. I was thinking of using a WOT switch to a relay to only power the pump up when I put the petal all the way to the floor, or will the pump pressurize the line and turn off when it see's a certain pressure in the line ?

 

Excellent thread but I couldnt find anything pertaining to the wiring using the utec instead of the variable controllers used with the regular kits.

 

Is there more than solenoid control? If I use the boost control map to control a WG solenoid can I still use the UTEc to control WI?
Is it worth doing?

 

The Methanol Injector kit had its own pump, and a solenoid. This particular system was designed for the pump to cycle periodically, to maintain 120psi of line pressure. It really depends on how the meth kit is designed.

The only thing the UTEC does it activate the solenoid, based on the parameters you setup. Hope that makes sense.

 

Yea it makes perfect sense, the utec controls the solenoid I have. The only thing im confused about is how I should power up my pump, hopefully the snow performance pump is similar to the one you guys used where it cycles itself periodically cause I really dont wanna have to listen to a pump the whole time im driving. Ill post after install let everyone know what i come up.

 

There are two seperate outputs. One is a dedicated output for controling an extra solenoid (water injection) . The other is a seperate dedicated output for your boost control solenoid. Like shariff said the spare soleniod output is controlled through the map in "and" type logic with different variables which I think you can use boost reference as one of then. And yes in my opinion very worth doing, gives you more control on how it is sprayed.

 

Can utec control aux injectors? Its a feature i would like to use.

 

From what I read up on it , it only has two outputs, one for boost solenoid and one for aux solenoid.

 

via the boost control map, I think it can. It's just a simple duty cyle table, so I dont see why it wouldnt work.

 

Very good. By chance does the duty cycle frequency follow RPM or is it fixed at a constant value?

I'm thinking EU for the G and UTEC for the Z.

 

RPM mapping.

 

Yes, I understand that it is RPM mapping. Which is great. But what I was asking was about the outut signal frequency.

The dutycycle is RPM map programable but what is the output frequeny? Does it mirror RPM or is it a fixed frequency?

BTW anything new on the knock light?
