could i connect the generic load rpm dc output directly to a fuel injector and have ti work properly or is it not the correct signal

 

Huh?
What are you trying to do?

i want to install 2 additional injectors to spray methanol. if load rpm output will work for this it would be great b/c i could have everything in one box instead of having to get an additional methanol injection controller.

 

Yes apparently you can connect additional injectors as the generic load rpm dc output.

Only one issue. Current draw. (Not sure how much you will require and I can't remember what the haltech ratings are) I will be using an FJO aux driver box to drive the FJO solenoid for my methanol injection. (Well at least that is what I was hoping to do as a winter project.)

The Haltech would not be used to drive an injector. It's used to drive the injection pump through a relay. The pump pressure is controlled by the duty cycle. You can vary the duty cycle with the Haltech. By varying pressure you vary flow through the constant rate injection nozzles. That's how all the controllers in the commerically available kits do it. You're wanting to drive a fuel injector solenoid. That's not what I was referring to in the other post that got you headed down this line of thought.

As for the relay any of the Bosch relays will work. Someone on the Haltech forum posted this though and it's a great idea. Solid state relays...

did some research:
as far as solid state relays here are some
http://www.futurlec.com/RelSS.shtml
the one that seemed to suit driving a pump the best is only good for 63Hz. While this is ok if you want to control flow through the nozzle via controlling the pressure of the pump. The modern systems are moving to solenoid controlled AI. The reasoning behind this is that the meth atomizes better at higher pressure. Companies like fjo and cooling mist are using solenoids or high speed valves. I tried emailing fjo for specs on their solenoid but they ignore me so im looking atht he cooling mist h-hsv. according to their website it draws .49A, runs on 0-12V, and operates between 300 and 15000hz. According to haltech the pwm output can handle 1A. It will run on 0-12v as well. Here was their response to my question about the e8 being able to handle the valves frequencies:

The E8 will control the solenoid from 0-12000hz.
This will drive your solenoid perfectly. Simply select the a frequency
around 8000hz, and lower until the solenoid does not make a "clunking"
noise when operating.

I suppose if i really wanted to run fuel injectors as my meth injectors i would have to get the FJO injector box but that is an extra $190.

If a failsafe is desired a flow meter can be added and connected to the ecu/boost controller to make it jump to a lower boost setting/fuel map.

I think i am going to go this route...i guess it means ditching the e6x. o well. if anyone actually reads this i hope it helps a bit

 

I've thought the same thing about using something similar to a nitrous solenoid instead of driving the pump directly. Does seem like it might be a more sound approach. You could use a simple load based PWM output to arm the pump at say 0 psi to prime the system and then begin injecting at 12 psi or whatever you deem appropriate.

Maybe Claudio can answer the question about the load rating of the PWM outputs. I know I've ran nitrous solenoids directly off an E6X in the past without issue though I can't be positive it was the correct thing to do.

 

I may be confused then. FJO racing says I need this http://www.fjoracing.com/products/injdrvr/ to be able to use my haltech E8 to drive their water methanol kit via my DC generic output. I gather its to run their Water Injection Solenoid Nozzle.

They said something about possible burning out the haltech due to the current/amout of times it fires?

Ok. I just looked it up. Its not that driver box but something similiar to this I would guess. It was alot cheaper whatever they quoted me on the phone by half the price!

 

fjo is using a different type of solenoid then coolingmist. the specs i gave above were for the s-hsv from cooling mist
