Uncategorized - 100_1589
my other post has more info on the situation, but i just rebuilt the car and deleted egr and this is the problem

99v6stang · April 26th, 2008, 12:42 PM

here is some info about my car...

- F150 4.2l block

- Ported and polished heads

- Ported and polished lower intake

- Ported and polished upper and throttle body

-Morana racing 224/224 camshaft

- Hardend pushrods

- Comp Cam springs

- 4.10's and posi

- Mac longtube headers

- Mac hi-flow catted h-pipe and cat back

the car was tuned to run with all of this via sniper but not tuned for the egr delete. the car had these mods before the rebuild and worked fine. I not longer have the sniper tuner but have an xcal 3.

do you have a wide band 02 ?

99v6stang · April 26th, 2008, 12:44 PM

no

99v6stang · April 26th, 2008, 12:45 PM

but the car ran fine with these mods before, so im thinking egr delete, the timing, or i need a new tune for some random reason?

HMUSN · April 26th, 2008, 12:45 PM

get one. you def. need one for your mods.

in the mean time try data logging with your xcal and it will give you a better idea of what the issue is..

99v6stang · April 26th, 2008, 12:46 PM

also i drilled out the egr ports in the lower intake and didnt weld them shut because the egr is blocked off anyways, could this be a problem? Uncategorized - 000_0023

99v6stang · April 26th, 2008, 12:47 PM

ive never used the xcal and have no instructions, what do i do with it?

HMUSN · April 26th, 2008, 12:49 PM

that could def be an issue and to use the xcal simply plug it into the obd2 port and use the menu. it's pretty simple

99v6stang · April 26th, 2008, 12:51 PM

so those ports should be blocked off? i cant imagine why because there is an open hole through them anyways, i just made it bigger and the egr is capped off anyways, but im going to go try that with the xcal, do i have to run the car to datalog im assuming?

HMUSN · April 26th, 2008, 12:53 PM

yes the car should be running.

the egr could have had a vaccum is what I'm implying.

If you don't have a WB how do you know its running lean?

99v6stang · April 26th, 2008, 01:01 PM

i was assuming by looking at the spark plugs, the xcal says unable to start data log

99v6stang · April 26th, 2008, 01:13 PM

okey i did some dataloging, how do i get it to the computer?

99v6stang · April 26th, 2008, 01:16 PM

where does this hose go? Uncategorized - 000_0032

99v6stang · April 26th, 2008, 01:20 PM

okey im downloading the live link software, what parts do you want me to tell you? can i post the whole thing online? and any ideas about where that hose goes?

GreenFaleen · April 26th, 2008, 02:11 PM

can you up your fuel any with your x-cal? seems when you widened the ports your allowing more air from somewhere, add a bit of fuel.

99v6stang · April 26th, 2008, 02:15 PM

is that user adjustable? ive never used sct i wonder if i can do that. This damn live link software wont let me install the drivers to datalog

99v6stang · April 26th, 2008, 02:17 PM

my car is tuned with sniper, so not if i tune it with xcal, would i need the entire tune? Not just be able to increase the fuel?

ESG-642T · April 26th, 2008, 02:35 PM

Where is your sniper tuner?

I think your gonna have to flash the car back to stock, and then get a tune with the xcal!
