Hey guys,

Please without flaming me on my engine management setup help answer this question.... I will be changing over EVENTUALLY...

The car is run with a JWT ECU and has e-manage on top of that to compinsate for the 64# injectors and also a Aquamist meth kit.

When I bought the car from Joe, the meth kit never worked from day one. Does anyone know exactly how this should be hooked up the e-manage and where I might be able to program it (if I have to)? :confused:

it can be programmed to run from the jwt ecu or most kits have a progressive controller set to come on at a cetain boost level and are fine tuned with the jets and control unit depending on the manufacture. So the emanage would not control it. it should have its own controller that has a pressure switch that is adjustable.

Hmm... I'll have to look into that. When I bought the car, I was told that the e-manage controlled the meth spray. ...If it doesn't, I don't know what the point of it being in there is. I would think the JWT ECU would've been enough.

Is it because the car is using 64# injectors? I don't know who would make the injectors or what they're capable of handling for fuel pressure, but right now they're at 4-bar and Jim Wolf basically said they don't have a program for those size injectors.

I am not a emanage expert so it may be able to signal the controller to come on. The injectors if they are 64lb are 74lb at 4bar or 775cc. lb/hr x10.5= cc/min

So basically because they are running more fuel pressure, they are essentially no longer a 64# injector? Why would that be, just because the injector was not designed to operate at that amount of pressure?

most injectors are rated at a 3bar flow rate if you increase fuel pressure you increase flow to a point where the injector goes static. rc engineering has a nice injector calculator on their website.

yes the injector flow more or less depending on the fuel pressure. example 370cc at 3bar and are 420-440cc at 4bar. here is link to rc's injector calculator http://www.rceng.com/technical.aspx

Great info, thanks!

the emanage is very easy to set up, ive been running for years with my stock ecu no problems, i get 30+ mpg highway cruising.
if you want to hook up the methanol to the emanage id use the port for extra injectors (sub injector map), and have the emanage fire it under certain load, pressure (mapsensor) its not hard to figure out

Great info man. Can you point in me in the right direction for some good info on how to do this?

if i were to do it, i would find the pin out for the sub injector on the emanage, theres 2 of them, then ill splice them into one wire and run it to a relay, this relay will trigger the solenoid to activate the water injection

then i would activate the map in the emanage (sub injector) make sure u have a pressure sensor in the greddy boost port this way u can graph it and figure out what voltage relates to what psi, and use that to trigger the solenoid with pressure vs rpm. in that map u have a chance to activate it with dutycycle % just figure out where u want the meth to come on at and add 100% duty cycle there, and every where else 0

for instance if you want it to come on at 10psi, then at 2.19 volts and above using the greddy pressure sensor at say 4000rpms and above input 100% duty cycle

thats the general idea i think u just have to double check if the emanage sub injector output is a ground or power, most likely a ground, if its a ground then wired up the relay for the solenoid with ignition "on" power and ground it in the emanage

What if I don't have a Greddy pressure sensor? Can I do against my MAF in reference to the voltage it sees from metered air?

yes you can, just map trace it and see at voltages you get the most boost and go from there, it just wont be as precise or accurate as using the map sensor, but it can work

if u dont want to buy the greddy pressure sensor, make your own using a gm 3 bar or do what i do and rig up a motorola map sensor 2.5 or 3 bar, the motorola map sensors are like 25 bucks, and i found a plug from my computer that worked in the emanage
