Fuel QUESTION

[ms3guy22]

Alright, so after recent events in the modding world, it has become apparent that even with a hi-flow pump. It might not be enough to properly fuel our cars. This is extremely frustrating because I'm here dragging my feet waiting for the industry to catch up to me. I'm not overly concerned but, I just can't ponder the fact that,..........i can't do anything else. Being in the service, i've always been trained that if you have a gripe with something, provide a alternative.
I"ve got no clue on if this will work but here is an idea. It might be the stupidest thing out there, but its all I have:
1.Say f@#$ the cam driven fuel pump.
2.Run a new line from the tank with a inline hi flow pump.
3.Find a way to control the pump with provide wires from ecu or where the stock pump was at.
4.Connected the new line to manifold or where ever possible preferrably to where the stock system hooks up in the engine.

Now be easy i'm just seeing if its plausible

Not unless you can find an electric pump that produces over 1885psi. You could try to work in a pully driven pump, but it's going to have similar issues as the cdfp if you can even get it working. That would also take a bit of moding.

 

[ms3guy22]

forgot about the psi thing, what about running a seperate line from the tank into a single injector which is tapped into the manifold and runs off of ecu from the cam driven pump

 

[ATE BALLER]

An added injector has been discussed, but right now it would be too dangerous. If you were to hit fuel cut and the added inject still fires, the motor could grenade.

Literally.(nervous)

 

[ms3guy22]

why could you not make the injector cut out when the engine cuts out. I mean the ecu makes the car quit why can't you make the injector quit.

The guy that blew his motor in his MS6 and rebuilt the whole thing with the GT3071R, what did he do? I'm trying to figure out the alternatives because I'm looking into building the bottom end and adding a bigger turbo pretty soon.

 

[ATE BALLER]

He still hasn't been able to get it tuned. It's like a pitbull with a shock collar around it's neck.

For the same reason we can't? Issues with getting enough fuel and pressure?

 

[ms3guy22]

miata's run extra injectors with out blowing up.

 

[ATE BALLER]

Miata's aren't direct injected.

Yeah, Chris's tuner was unable to get around the fuel cut w/o backing off boost.

i think the high pressure pump will do the trick. from what i have seen from laloosh anyways. it helped his problem until he tweaked the standback, then the cut came back. it is now my understanding that he removed the standback and is hitting 19 psi on the stock boost system with no MAP modifying device. without that you will get cut with any pump. unfortunatly there arent enough guys with proper pumps out there to tell us their results.
i do think an extra injector system would work just fine on this car. i am willing to bet that when the car triggers fuel cut it interupts the ground connection to the injectors. that makes senst to me anyways by doing that it can cut all the injectors at once, rather than trying to cut them all individually. if that is the case you just tap you added injecor into the same shared ground source. then it will cut along with all the rest. i may be 100 % wrong but i have seen that method on other systems in the past. it would not be hard to test, all you need is a volt meter and a co-pilot !

 

[ms3guy22]

For sure, I'm not backing txs at all on this but, since i've moved into all their products i've not hit fuel cut once. swear to god!! i've bounced her off the rev limiter even. Fuel cuts not my issue, my issue isn't being able to clean up the a/f and gain power.

And now that Cobb dropped the MS6 AP, i dont know what options he is left with. Perhaps, sell me the motor and let me use it. Poor guy. I feel for the MS6 community right now as to being really limited.

Cpe ems V. 2 is coming, that is for the ms3/ms6. Right?

 

[Haltech]

Yea Red, problem is, its still an interceptor. You dont get 100% of the computer. If it wants to add timing, it will.

 

[redspeed]

Well, is something. We gona have to wait and see what the capabilities are. I really hope is the product they are making it to be. But yeah, I get what you're saying.

I doubt that this is correct. From what I have read about the Direct Injection system, timing of the fuel spraying into the cylinder is critical for that oh so beneficial cooling effect as the fuel atomizes in the cylinder. The implication is that the system has to have individual control over each injector.

 

[ms3guy22]

^ It doesn't matter, if you can find out how to make how to make one injector quit with fuel cut, you can then go ahead and make the aux injector quit at the same time.

U must use the cam driven fuel pump on a direct injected motor and second dont do s*** yet because absolutely no one knows if the fuel system even needs to be upgraded yet or if fuel delivery has anything to do with the fuel cutting issue. so just wait dude. ive learned that 99% of the people on here know s*** about this car. so just be paitent and do other mods in the mean time. have you done your down pipe, mid pipe, intake, motor mounts, upgraded the tranny fluid to mt-90 or boost controller set to 18 psi yet??? if not do those first. good luck!
