will do!!

 

I live in Colorado Springs and its 6800 feet unlike denver's low sections.

My corvette is a 2 BAR MAP Operating system and runs the Chevy Cobalt's MAP sensor. I didnt buy the 2 bar MAP with the meth kit because I already have one to run the engine. In HPtuners, this gives my car fueling control by boost pressure. If you go into HPtuners for fueling you normally see a table for PE fueling, I also have a Boost PE table that adds fuel by boost pressure. This is needed for cars over the MAF range because the car wouldnt vary fueling once the MAF is exhauseted and my car was killing the MAF range by 5000rpms. My MAP 1/2's the voltage of a 1 BAR MAP to double the pressure range. So a .79 reading at my elevation correspondes to the full MAP you get at sea level on a 1 BAR and its .39 or so for the 2 BAR. Map sensors like the Hummer are what you will see in your car. They read 0-5 volts too but full voltage for the 1 BAR is around zero vacume. When you key on it reads full voltage for your elevation. When you start your car, you should see about .49 or so. You can trigger for any value above that and coupled with a foot switch on the gas pedal, it can be at 1/2 throttle and the required MAP valtage.

The control unit activates by voltage tapped from the center green wire. While you are driving the voltage is not 5 volts unless the manifold goes to 0 vacume which it does when you roll into the throttle. You will hit vacume for slight roll-ins too. On my car the MAP is a 2 BAR and zero vacume would be at about 1.7 volts or for me and about 3.5 for a one BAR on the Hummer. My car's meth turn on is adjusted for about 0.5psi pressure or about 1.8-2.0 volts. If I took it out and put it in the Hummer it would be spraying at idle. You can make the unit spray before 0 vacume.

On your car, it very much can be set to spray before full voltage. It can spray whenever you are accelerating which is basically what you want as long as you use a simple foot pedal switch. Everyone would be needing meth if the GAS pedal is 1/2 or 3/4 of way down and accelerating.

You must use a much smaller nozzle and the intial and turn-on are separate adjustments. It isnt an off-on switch. A slight mist at .8 for you and full at WOT is possible.


I never mentioned this system and suggested the one ECS (supporting tuner here) is using. By using the MAP trigger and the foot pedal switch is does work. Others around here use the snow performance set-up because Snow's store is here and they all use the same set-up on nitrous only cars.

A 5-7gph nozzle is used with MAP triggers and an RPM lock-out although my brother's idea works just as well.

You are trying to reinvent the wheel here but keep in mind the kit is in use and JB has one working now on his car.

The pumps are the ones you have a link to but Alky Control deletes the switch for power interupt and changes all seals to be compatible with 100% methanol. It is a modified pump and I wouldnt try sourcing from outside the circle.

I also updated the install to let everyone kjnow it these systems are meant to have control units mounted inside the vehicle. Mine is where it is for an R&D reason and it isnt mounted in free air. Its insulated against water contamination and cant get wet. Dont copy my install. I merely showed pics to let you see control functions and how to adjust the system and didnt suggest locations. I thought it was clear. Because I do so much R&D on this car, I need all adjustments and electrical wires open and accessible from th under the hood. My hood is physically open 70% of the time this car is in existence.

 

Nice write up and you provided lots of good info. I liked water alky injection systems for a long time. I first used the old low tech injections back in the 80's to keep my Hemi Challenger, and then my SS396 375 hp Camaro (both NA) running on pump gas when high octane and lead was taken out of the gas. Later on I had a little Turbo Lazer that used the low tech water injection and it also worked good.
One thing for you to think about is a simple add on those systems used was an oil pressure switch to keep the system from spraying when the engine was not running, and some also used a water temp switch to turn the system on when the engine was warmed up.
On the water methanol mix being termed flammable I remember reading someplace it is due to government regulations which classify it as flammable with more then 50% methanol and under 50% it would not be under the classification. I know its dumb when you think 51% methanol is a flammable but 49% is not but I guess they have to put a limit someplace. It’s like needing or not needing a roll bar being separated by .02 secs!

I'm almost finished my Meth setup, I only lack the IAT sender and wiring.
I took some scans 1-4 th gears and adjusted my timing, keep in mind
the IAT's are still reading upstream from the Meth nozzle. I'm running
WW fluid untill I can figure out a place to mount the IAT sender after the Meth nozzle so I can change the IAT tables and finish it like posted by Spin, that way when the IAT's are high (inop meth) the timing will be controlled, and not damage the engine, then I will start to run Methanol. also I need to change the ramp where the Meth comes on to a more subtle point.
then it will be time to go down the 1/4 mile!!
I sent Spin a copy of my scans, I'm sure he will share some insight
on what I need to finish it!!

 

how do you add the interior led/ status light to the ecs kit?

 

So are you saying we can run a WW fluid/Water mix as a form of injection?

 

Yes and its been done even by members in this thread and the maker of the Alky Control system from ECS which I use and recommend.

Awesome thread

 

I did ask ECS about this system in December and was told it was still in development

Can anyone (Spin) confirm if development is complete?

My ECS/Alky Meth system works great and the activation is Maf controled Vs Map, very easy to adjust, I spoke to Spin and Julio from Alky controls for some insight on the fine tuning, It was not hard. Product support is first class!!
ECS and Alky controls Meth kit is a great unit and easy to install.

 

You spoke to Julio, but who did you speak to at ECS?

The gentleman I exchanged emails with at ECS was not aware that the product was yet available (see my post above)

Thanks
John

 

ECS supplied the basic kit to me which I modified to run with Julio's MAF switch which is not available yet. You buy the kit from ECS and run it with the experimental MAF box from Alky Control or you adjust the meth to fire when the MAP is .75% of full for your altitude with a foot pedal switch like you use on nitrous systems to have it not fire unless you're at 60-70% throttle.

You should also request a 7gph nozzle as the 15 is way too big for this application.

 

Spin is right, I spoke to Him and Julio,
Alky controls is close to me, an hour.
The ECS kit with MAF controler is a RD setup.
There was 6 units sent out for trial, it works for me, however they need to make sure it's safe and dependable before it's release.

 

Agreed - that sounds about right

So does any one know when the R&D will be complete and teh units offered for sale?

Have to mark this one. About to do H/C on my C6 this summer. Thanks for the writeup and your support for SJCH.

We prefer to have plenty of data, both track and street, before releasing a product. Being that its pretty snowy here now, it's going to be a little while before our track testing can be done, but we will definately know when it's done.

Being that this is just a little spin off of an existing well proven product, I do not see a problem, but I would rather do the testing ourselves or with someone like Spinmonster.

Thanks

 

My situation is the exact opposite. I live in Bahrain and in 1 month the temperatures will be back at 35deg C and by May in the 40's. By April I need this system up and running hence my interest now.

Anyway - keep me posted on this as I am a guaranteed buyer

I volunteer my car as a donor/test car.. you know I'll push the car to the limit.
