So 14 + 14 + 14 + 14 +14 + 14 = 9 gauge?

dvst8r · « **Reply #301 on:** June 21, 2009, 12:39:07 AM »

It seems more realistic to me that:

14ga + 14ga = ~7ga

and 14 + 14 + 14 + 14 + 14 + 14= ~ 2 gauge

But I really don't know, hence the reason I asked the question in the first place.

If it were mine it would get the ID injectors (I know they dont flow like 1600s, but there will be PLENTY for his goal, and they will idle WAY fucking better than the 1600s).

1525cc if you crank the base pressure to be exact

Depends on the fuel you use to test them.

131 psi for pump gas, 101 psi for test fluid/c16. Not many conventional pumps flow that well at such "high" pressures, figure any engine needing that size injector needs 30+ psi resulting in that pressure added on top of the base.

Mister Crane, you've read a lot on the internets but if you'd read as long as most of our OGs you'd be aware of how shitty FMU-like fuel pressures are as your fuel lines become prone to leak and burst. All this aside, it's still cheaper to run a secondary rail that comes on with VTEC, replace factory injector drivers with CS452/CS453, or one of the other tricks that are pretty much commonplace. I know I'd rather gang a couple cheap and readily available Walbros than fool around with some oddball shit that isn't readily available and isn't proven.

Just because the technology is new does not mean it is worthwhile. For example: VTEC. That's a worthless sticker technology if I've ever seen one.

Since we are delving into injectors and such, JD what do you use to bring the voltage up at the injector to run things like 1600's?

IMHO ID1000's seem to be a good injector, just as long as you run them as a 880 - 1200cc injector.

Joseph Davis · « **Reply #304 on:** June 21, 2009, 02:03:16 AM »

I don't, that's Sewell's trick but it's nothing more than a buck-boost regulator with some ass behind it. Not a bad idea, that.

My only 1600cc experience was with an FJO driver box; they wouldn't idle cleanly, precise injector control at idle and light throttle was complete shit, they were taken off and shelved.

I've nothing against the Injector Dynamics stuff, but I haven't had any problems out of plain jane Precisions. The cars idle smoothly, and make 600 to 700-something whp off of a set of four. I can deal with that.

my pops used these (16)injectors on his pro 5.0 car way before Tony1 made them all the rage on H.T, i have said it before these injectors are all the rage and then some, some people might like to be stuck back in 1990 technology but some choose not to, and yes i know all about the shitty fmu like symptoms of a rising rate system but lets face it, if your trying to get 1200 cc+ worth of fuel your probably not running the typical run of the mill broke

setup, to me it seems way easier and simplier to go walbro intank to a bosch 044 mounted on the firewall to a set of i.d injectors, no secondary injectors to fail no switch to not engage. something can be said for following the old K.I.S.S method but different strokes for different folks

Joseph Davis · « **Reply #306 on:** June 21, 2009, 09:46:33 PM »

The injectors themselves are switches that may or may not engage. Also, the ignitor. Ad nauseam. If you really thing staged injectors are hugely complex and prone to failure... uh, okay. Have you ever traced the data chain going from your chip to MCU???

email from FJO. I think my local wiser wire rope shop has some 0ga welding cable for $2 a foot. I am going to hit them up.

To verify the ground use an ohm meter and measure the resistance (power off) between the ground of the driver box and the negative terminal of the battery. You should have less than 2 ohms. As a general rule we don't recommend grounding to the engine components because you also have the plugs grounding through it and that can cause noise. At this point it is hard to say what is happening without being able to watch the injector pulses with an osciliscope. It is not a problem we have encountered before so I am assuming it's not the box ... but I can't say for 100%.

umm.. i still have a shit load of 0ga and also 2 and 4ga left from my shop!

Did anyone ever watch the fuel pressure when he was on the dyno making eleventymillion low cam pulls? I am starting to wonder if he has a bad FPR?

Levi did you run the adjustable FPR on the LS setup as well?

Urban Indian · « **Reply #310 on:** June 27, 2009, 01:10:29 PM »

yup same same. I am going to ground the ecu to the frame aswell. gotta do what I can niggas

dvst8r · « **Reply #311 on:** June 27, 2009, 02:22:28 PM »

Try grabbing a stock FPR or borrow another adjustable one and see if anything changes. DO ONE ADJUSTMENT AT A TIME! This way you will know what worked and what didn't.

Urban Indian · « **Reply #312 on:** June 27, 2009, 08:32:08 PM »

maybe try that after I do grounds.

and seeing as its a Aeromotive i think it would be good to go.

FUCK i just fixed the most ghetto return line ever.......

but I used 5/8 double wire hydrolic hose..... its too thick and wont let me use my dumptube so I am just leaving it apart until I get that stainless line in.

I had my return line good to go for $17.11 from Princess Auto........ until it wont let me use my dump tube. GHEY

Joseph Davis · « **Reply #313 on:** June 27, 2009, 10:11:28 PM »

Aeromotive are generally good, but they do have diaphragm problems.

Anything can have a bad run or fail, and with all the bad luck this car has had I wouldn't over look anything. The battery relocation and the FPR are two of the few things that have been common to all of the motors.

d-rail · « **Reply #315 on:** June 28, 2009, 03:44:26 AM »

Have you tried by passing the battery relocation and puttin it back to stock along with all the wires? Just a thought.

except i have this weird thing called a catchcan sitting there. Trying to revert back to stock wiring right now

Urban Indian · « **Reply #317 on:** July 10, 2009, 02:48:04 AM »

ok so grounded the thermostat housing to the frame, battery to the tranny

problem still there. I am going to try and put and put a different tune in there to see if it changes anything.

Then maybe ground the ECU to the frame. then I guess try and find a FPR (maybe just order a new one and exchange it)

I cant figure anything else out to be honest, I feel even if I change my injectors then shit will still be the same.

can you zip tie a vid camera to car rigged to capture the FPR readings at speed/ under tip in and part throttle? or can you do this from under the hood and make it stumble whiles its parked? Would be interesting to see or if nothing else rule it out.

It was spelled out for you how to GROUND the car... If it fixes it or not, still should be done that way.

ratcityrex · « **Reply #321 on:** July 10, 2009, 12:34:11 PM »

Fuck it just put a hose barb where your fpr is and run a hose from it to the gauge that is duct taped to your windshield!

I remember leed talking about doing that to a car years ago as a last resort and they figured it out that way.

Urban Indian · « **Reply #322 on:** July 10, 2009, 03:15:11 PM »

I ordered a new fpr. I will put another gauge in and then tape my camera to the car. Do that tonight maybe actually, and then I only have to ground the ecu and then I have no other grounds to do, I will ground the ecu to the tranny aswell as the thermo stat housing. Any more brilliant ideas brett?

Battery To BLOCK.
Block to chassis
Block to frame
Block to T-stat
Block to ect...

You get the idea now I am sure.

This is what I went over with him two days ago, why has this not been done
