wow.... my eyes are focused on you guys....tell more....more
more....more.....

 

In theory it shouldn't. I would estimate (I do not know for sure) that because the ECU has no info coming from the 5th injector controler (thus it cannot 'see' it) that it will only rely on it's current sensing. By it only looking at it's current sensing, it should see " Well, I have X air coming in, I'm pulsing at x MS on the injectors I know exist, and my 02 voltage looks to be in the right spot.. so.. I don't have to do anything".

It should work almost exactly like a nitrous system now that I think about it... except that instead of the fuel being injected with nitrous, it's being injected with extra air from the blower.

 

^^^ Do you think it will or could shut down fuel to the four original injectors?

This may be a stupid question, but I would think if it were sensing too much fuel and not know there is a 5th injector, it would shut down fuel to the original four and cause a lean condition.

I guess thats what the O2 sensor is for?

And the ECU SHOULD keep it within the 14.7 ratio or whatever it is, even with the fif injector (a little Dave Chappelle comedy in there with the 'fif')?

 

Certainly the ecu will not know the 5th injector is there, but I guess if it notices changes in the AFR its corrections wouldn't interfere too much, but in f/i you do want to run a tad rich right?

 

^^^ Yes, that's why I asked. I don't think there is a way to run slightly rich as a safety feature...But I have been wrong before.

 

This 5th injector controller won't interfere with the stock fuel system or ECU at all. It is set up to add fuel as the oxygen sensor and MAF sensor see fit.

Since this fuel is being added in while the ECU and stock fuel system don't know it, it keeps the fuel system in check as far as the computer can tell. The engine won't run lean and that means the ECU isn't trying to make up for missing fuel because of the blower. The missing fuel is dropped in as needed by the independant 5th injector controller.

 

Here's what I see as a problem though....By the time the O2 sensor sees the lean condition and starts to add fuel, it's already too late...it has already ran lean, you see where I'm going with this? As a 'safeguard', there should be a way to anticipate when it will run lean and add fuel before hand.

Sorry for being off topic and also....PLEASE if I have something wrong here...correct me! I'm here to learn!

 

Thats why this device reads the MAF also. PLUS you can set the sensativity of the device as well. You don't run lean. Well you may run a teeny, tiny bit lean for a milisecond in the worst case.

 

Also, your stock injectors should be able to handle the sudden requirement for fuel and give the 5th injector time to fire up and suppliment before any issues arrise.

As it isn't tested on THIS car yet, we don't know how it will all play out for 100% certainty yet. However, this is going to be setup on TWO cars within the next month or two and testing will begin.

 

I asked my friend that originally made this device repeatedly if it should work on our cars. His words exactly were...

"This device will work on any car with a MAF and an oxygen sensor."

He has been using this device on his turbo Escort for like two years now. He drives his car reliably everyday in the summers.

I am confident in this device and I plan on getting these built for anyone that wants them. All I ask for is time for us to get them tried out on our prototypes and then I'll start building them for people. As far as cost, I will determine that as soon as I learn how long it takes for me to make them. Materials are only about $5, so most of the cost is labor.

Stay tuned.

 

After reading on these, I really want one of these 'gizmos' for my Tacoma! I have been working on a turbo kit for some time, and have everything made as far as the exhaust and intake, but have not found an easy 'cheap' way to keep the fuel management where it needs to be. I think this is what I've been looking for! I hope we can get a few extra made...I'll get one!

 

I will talk with my friend, he is the electrical master that came up with it. I can tell you right now he won't want to build a ton of these so he is gonna have to show me how and I will do it.

Once I am making these 5th injector controllers I will offer them up for sale on here.

 

^^^ I totally understand. If I knew what parts I needed, I would build it myself, but I can't tell exactly what is needed by the pics. I think this is EXACTLY what I've been looking for to use on the Tacoma! Just keep us informed! THX.

 

^^^ BTW...ctruss...I work at a metal fab shop. I can make the cases/mounting plates if you need them. I just need dimensions and details as to what you need exactly. I may be able to do the holes and such too, but it will take some accurate measuring by you to let me know where the locations are supposed to be. It shouldn't be an issue to whip up 10-15 and ship them to you.

 

UPDATE:

Getting some aluminum stock to start making a few test plates and brackets. I should hvae the blower ON the car for durability testing this weekend. By that I mean it will be mounted but not functioning. I want to test the bracket setup in hard driving and heat to check for warping, etc so fourth.

An intercooler is being deloped as well as the fuel controler and 5th injector setup. We are looking into powdercoating for all of the parts to provide a fresh look.

If it isn't obvious at this point, Ctruss and Myself are going to be jointly developing this from here on out to provide a complete kit with full intercooler options.

More to come!

 

I am getting my aluminum together as well as building the first few 5th injector controllers over the next week or so.

I am hunting down my blower but I do have a gutted one to use to make the mounts with.

We will keep you updated.

 

I would like to see this finished...so get a move on. :D

Seriously though, I have heard that M62 blower and the Eaton blower on the cavaliers and let me tell you they SCREAM!! So loud in side the car under boost. It is definitely the supercharger whine I wish I had. But I will take the whistle of my TRD charger.

 

Now that the Nationwide Ames, IA show is over I am going to spend a little more time on this project.

Look for updates soon.

 

A buddy of mine made a supprise visit, I was tied up this weekend so no more progress on my end was made. I am, however, going to be mounting the system in the next few days with boost HOPEFULLY within a few weeks.

Wee!!

 

any update?
