Can a E6X be used to control 6 injectors (this is on a 2 rotor application).

crispeed

Yes.

Yup, simple, id connect the primaries the way you'd normally would, then the secondaries would be 4, make sure you know what impedance they are so you can set the current output. What flow will you use?

im thinking about using e85 so , 850s for the primarys and 1680 for the secondary and tertiarys. will i be able to control the secondarys and tertiary injectors seperately or will they be connected together?

Are you going to run 100% ethanol? or mixing? and how much boost? are you going to run 4x1600cc injectors as your secondaries? cause thats what you can do, stage the 4 secondaries, as if they were just 2 injectors.

Im going to mix. E85 in the summer is 95% ethanol or so they say and in the winter it is around 70%. The gasoline helps the cars start when its cold. I am going to try to run it at a 70% ethanol for the entire year.

Im still in the planning stages of this so i dont have a good idea for how much boost im going to run.

the 1600s will be secondarys.

Im a bit confused on what "staged" means. Does it mean that i will be able to control one pair of injectors with each injector driver. so the each primary will have its own driver, the first set of secondarys will be on on driver and the second set of secondarys will have its own driver? Will this allow me to control the two sets of secondarys seperately?

I wanna ask, how much is the ethanol per galon anyway? you do realize that running at that % of ethanol requires a lot of fuel to be dumped in the engine? so, in a sense you do use more quantities of fuel, almost twice as much, to get the same or better results as with gasoline? personally i would only use ethanol or methanol on race cars, its tricky and putting the car away with methanol or ethanol is problematic, it clogs inyectors, and is corrosive to aluminum. Thats why they call them "ethanol friendly cars".

Thats my 2 cents.

Anyway, stagging injection is what you use on a rotary, you first run on the primaries untill boost comes along then you turn the secondaries on. If you look at almost all rotary maps, thats how its setup.

But, with meth or eth you'll have to have bigger primaries, i would think.

like claudio said ethanol burns like 60% faster to achieve the same output... so figure that you'll need 60% more fuel to go the same distance as with regular gas.... also EVERYTHING has to be changed...pump,fuel lines, injectors,gas tank.... all have to be changed cause ethanol is corrosive, and will eat through your fuel lines... you need stainless steel lines etc.
but it's detination point is much friendlier and burns ALOT cleaner.

Ill run to my gas station and check the E85 price tomarrow.
The main reason for trying to run ethanol is like jumbogumbp said, it has a much friendlier detination point.
I know this is going to be a pricey project but it should be interesting.

the E85 at the gas station by my house is like 2.48 a gallon. I know its cheaper cause now gas here in vegas is about 2.60 for 87. My mom was tryin to put the E85 in my car because she thought it was just a cheaper gas.. haha..

RETed

No.
Haltech only can control two stages.
It sounds like you want a 3rd stage to control independly?

I have a question, since i have not walked up to an E85 supplying gas station to find out, is the ethanol sold in these stations is it pure or is it mixed to some percentage with the gasoline, i was under the impression that currently gas stations that sell E85 mix it with gasoline to something like 90/10, or 80/20, but nothing more, in these cases, what this is doing is making the gasoline gain a higher octane rating. This is what i thought, please correct me if im wrong.

At any rate, if you have to use pure ethanol you will probably have to spend more money both on quantity of fuel and on parts to handle it.

So, for a street car, pure ethanol will probably be a little pointless, but mixing it would be ideal.

Thats my 2 cents.

i did some poking around on the net and e85 is normally 90-95% ethanol in the summer and 70% in winter. Im going to run 70/30 ethanol/gas mix all year around. And experiment on using strait pump e85.

I do realize that its going to be expensive to do. Im going to have to put in a new fuel cell (300ish), a new pump (475) and 2 additional injectors (200$). Not to mention 300$ in fuel line and fittings. But that being said, if i wanted to be cheap i wouldnt even be thinking about this.

If you want a third stage you can piggy back the third stage injectors on the secondary injector drivers but wire the positive side of the third stage injectors to one of the pwm's via a relay and activate them with one of the programs that suit your needs. Then you'll have to compensate on the main map once the third stage comes online. Kinda crude but it works.

Maybe im just talking out of my *** here.... but the way i under stand things is that injector 1 output goes to 1 primary and injector 2 output goes to the 2 primary right? Ok so why dont we place both secondary injectors in injector 3, with one injector on the front and one on the rear, and the tertiarys on injector 4, with one on inj on the front and one on the rear? Wont i be able to control injector output 2 and 3 independently thus allowing me to have 3 stages on injection? Or is it a software issue?

crispeed

The software only allow you to control two stages. It's up to you to decide how many injectors you want on both stages. Again it's only two stages that are controlled via the software.

Nope.... you only have 2 pairs (or banks) of injectors. So, Inj1-2 outputs will control the 2 primaries, and Inj3-4 the 2 secondaries, thats it. I would use the Wastegate map to control the 2 tertiaries, that way you have control of them based on RPM/LOAD.

Anybody know if the PWM driver is strong enough? in any case, just use 2 high impedance injectors to be on the safe side.
