Thanks sohfast94 and great work . Looking forward to the next test run and getting back.

 

I know I'm slow but, I'll send it to you tonight...>

 

No problem, I'm looking forward to it

 

if your above referance was about elimanating the VSA throttle restrictor...its been done and ill gladly share ...scalbert and allmotor helped me...and it's just a couple resistors...the VSA button does need to be used or the ecu will throw a temp code if the wheels spin and vsa is not disabled

 

what terminals get the resistors and how much resistance?

 

We'll I put the 550's back in, and today is a different story from last week. With airflow adjustment made the cars idle Just Like Stock!!! The cars in my backyard, and being blocked in by my wifes car, so I can't take it out on the road, just yet. Anyway, I put the car into gear and floored it to about 4500 rpm, no hesitation at all. Last week the car wouldn't idle or rev up at all, but now it seems fine !!! Thanks for the tips Sohfast94!
It seems that the car is streetable, and that's a really good place to start out, because last week it was getting way too much fuel.
I'll write again when I take it on the steet :evilgrin: .

 

We'll it runs alot better, but there are still fuel issues though (too much of it). Off boost and under acceleration the car stumbles alot. Arrggh! I guess I'll have to go with additional injection instead.

 

Waht's your injector scaler at?

 

um scaler? I went from 270 to compensate to 550. the car stumbles when i get 1/2 or more into the throttle.

 

on the power side 10 watt 1 ohm and on the vsa 3 wire harness 8kon one side 2 k on the other watt doesnt matter joined to a center pin

 

So wtf is happening, too much fuel all at once, timing being pulled, vsa acting up even though it doesn't light up??? it really starts to pull (the engine), then it just falls on its face

thanx for the info Type R

 

Do you have a wide band AFR? If so what does it say when this happens? What is the timing at this particular point in the map?
What is the fuel setting by the E-manage? Have you tried to log the injector duty cycle compared to the stock cycle? There many ways to interpret this which are you most comfortable with? I would sya I'm fairly versatile when it comes to this stuff. Do you have a stick or auto? Did I already ask you that? (Just keeping you on your toes) What's the fuel pressure at tip in? Or when you start to step on it. Do you have an FMU? If so take it off your injectors have enough to not need it. If you refer to my previous post I referneced you and the size of your injectors.

 

Auto, no fuel setting to the E-Manage, no wide band but I can see alot of brown smoke fro m the exhaust when it stumbles so it's def. too rich, no adj. to timing, 43 psi at tip in.

 

I just took the car out right now, unhooked the VSA and the engine was cold. That Biatch accelerated up to 80 mph in just a couple of heartbeats wow! But after the car warmed up, it was the same old story, stumbles on throttle tip in. There's definately alot of potential there.

I guess I need to go get some resistors now for the VSA.

 

Okay here's what happens. Basically when the car is cold it's running in open loop so it's basically "learning" at that point. Not making part throttle corrections based on the target AFR table in the stock ECU which is ~14.6-7:1 Once you pass ~70% TP It will not be relying on the O2 sensor anymore and will be utilizing what is commanded in the traget AFR from the ECU. The trick here is to get the fuel threshold from the E-manage to meet when it goes into open loop. The 14.6-7:1 is okay when not under boost I would rather lower but, that is what you have to work with right now. Oh yeah you have PM.

 

Check that what's your Email address?

 

Yeah I did some fuel checks, the Walbro pump can't keep up with the 550's. I'm gonna upgrade the fuel system. That's why it would stumble, then go rich, the pump waz surging pretty bad and loosing pressure.

 

Oh yeah, vmax14@hotmail.com

Even though the car accelerated up to speed, it was still way lea up top.

I'm considering something kinda like this http://www.jegs.com//cgi-bin/ncommer...20&prmenbr=361 , total kit cost in the ballpark of $700.

Nice ! I'm gonna mount the pump, when I decide on which one, in my trunk, out in the open with alot of nice AN fittings to dress it up. I just hope the one I choose is quieter than the Mezier water pump I have runnin the IC system.

 

i believe your on the right track. the fuel pump provided by comptech may not be able to keep up with your fuel demand. Thats one reason others have added an additional injector into the IM. Since your goin to use larger injectors, you need a fuel pump that delivers more volume. If you use this pump, you'll have some major modifications to do to the existing fuel pickup in the tank, not impossible, but well thought out fabrication. You just don't add that fuel pump in line with the existing one, won't work. you'll have to take the old pump out, and fabricate an pickup to seal on the tank, then run that line to the new pump.

to really get fancy, and since your opting to use an aftermarket pump and larger injectors (and regardless of what some may think, for they have to think outside the norm, the guys running the extra injector, who will chime in) regardless of what argument they present, consider trying this. it may be pricey, but you have most of the power makers in place. Now to tune it properly. Take a look at this link.

Then, IMO you will have the proper hardware for fine tuning.

 

Yep, I will not be using any of the stock fuel system lines as they are about 5/16" in diameter, very restrictive. As for the pick up, I will be running a 6 AN size hose, as well as all the way to the front of the engine. A bulk head fitting and epoxy will be needed for the pickup. I think the fittings will run in the neighborhood of about $200, the hose about $80, the pump about $300, filters about $180, all around $750 total ( I know I can't add ). AN 6 is about what, 5/8" ? That should be more than adequate. Of course a reducer will be used for connecting the lines to the regulator. The fitting on the Comptech regulator is setup for 5/16", but I will be replacing it with a larger AN fitting.

Even with my current setup, stock injectors, E-manage, HBP, my system is lean and maxed out.

 

Holy shit, Bell Engineering has some nice regulators !

 

We're creating monsters here...maybe we'll need parachutes to go with our hood scoops.

 

Must feed the monster more food, er I mean fuel !!! I freaked my friend out at work yesterday, he couldn't believe how fast the car accelerates . I told him to wait till next week, 550's.

 

Did you take out the 550s and then you will reinstall them? How did the map etc.. from sohfast94 work out for you?
I hope it's all good news, my monster is Ok as long as it doesn't have to shift.

 

Right now I'm back to the 270's. I put the 550's in last week to test it out. I haven't received the Map from Sohfast94 yet; however, I have been able to configure a Map that allowed the car to idle just fine, just like stock. It took putting in some negative values in the air flow adjustment to cut the fuel back. I just placed a big order today to get things rolling. I'll be expecting a big package from Jeg's soon . I have to see what the safest mounting area for the pump is though.

 

They make some nice IC cores as well.

 

Check your Email.

 

With 550cc, you shouldn't use a rising-rate FMU... just a regular FPR should do. 6x550cc at 100psi is a heck of a lot of fuel!

 

they picked a bad time to be constantly buying fuel...

 

Yeah, I'm probably gonna end up getting a reular bypass regulator soon. I'm going to just unhook the vacuum line for now so I'll just be getting 43 psi to the injectors.

That should do it .

 

sohfast94 there must be a problem with the e-mail, I haven't received any messages on hotmail

The only message I have in my e-mail right now is from a billionare, Mr. Sipho, in south Africa trying to get me to help out with his mining export bussiness .

 

I think for a ~700whp setup, a CL-S would need (for driveability and ease of tuning):

i. 6x370cc injectors
ii. Comptech FMU so that 15psi of boost increases fuel pressure to 85psi
iii. 2x750cc secondary injectors

 

I have a new set of six RC 750cc injectors if anyone is interested, email me at desijigga786@yahoo.com

 

That looks like a nice formula.
Is this in your test plans???

 

allmotor is lucky, after the injectors, all he has to do is turn a screw to up the boost

 

Question: If oyu have the two additional injectors thhen why the FMU? The only reason the FMu would be untilized is because you don't have extra or "supplementary" injection. Being that you have that itr negates all logic of the FMU. In thhe broader spectrum the injctors are ony to support up to 43-7psi under noraml conditions. They are not rated for that high of a pressure especially not when it comes to consistency and longevity of the injector which is directly related to engine life becasue if you injector gets stuck open from running that much pressure then say GOOD BYE! That's why I gripe about FMU's and such. There's always a better way.

 

Chemmech and SCTL-SS you guys are nuts
