First off I'm a new with tunning! Well I received Toms tune and just figured out I could tweak it. So, I went out to change the idle down some (800) I did this and when I turned the car on it idled right above the I guess its the 825-50 line(the one right below the 1,000rpm) as it did before. So I figured I would screw down the little bolt on the TB and it helped little to none. The thing is my idle is pretty good sometimes it jumps 200rpm or so. I'm just aggravated it won't go down. One last thing. It says data logging and that has my curiosity! What does this data logging actually log? Which one of these things should I log and can it help Tom tweak the tune for max hp?

Bump.. anyone?

sorry i cant help but how is the tune? i ordered mine yesterday

I'm enjoying it thus far! I changed a few things though. -1mph for 1-2 and 2-3 and the rev and idle though the idle didn't change for some reason? Idk.

do you have an atx or mtx?

i have a atx

What is the name of the actual parameter you are changing? Are you scrolling to the value you want and pressing select?

I did both idle ones. I believe one was wet and the other dry? yes i hit select and the check mark came up next to it when i went back to check it. Ill go make sure what it actually was.

i have dry and new both at 800rpm.

It's actually drv and neu for drive and neutral. I seem to remember your idle was already set to 800rpm.

The factory tach is not perfect...being off a bit is not uncommon. If you change the values really low or really high does the idle change?

Oh ok. Tom sets it at 925 and when I set it at 800 I couldn't tell a diference. I'll go set it at something very low for the hell of it and see what happens. Oh btw I also check the digital one in the dash and it was going between 910-930ish.

I just looked at the file. What you sent me had it set to 800.

Hm idk. But I have a seriouse issue now. My car isn't starting. Everything like lights work just fine music and all and but it turn over. It's as if the car isn't getting any battery..

It said complete and didn't seem to have any problems loading the tune. Also i tried to return it to stock and i got the same thing. I'll go try to find someone so i can jump my car just to be sure it isnt the battery.

how did that happen.

?! idk! I changed the idle and drive rpm to 600 loaded it up and now the car wont even try to start. I got the codes P1000 and P1601 I think it was. I didn't tell me anything usefull about those codes. No one will be here to jump the car til 4 and i dont think that will even work..

LOL ok guys I figured out the problem! I grabbed the wrong keys.. They both look the same! Ah, well at least the cars computer isnt fried or something =).

so did it start??

the higher idle could b a vac leak, there real fun to pin point[clap]

Yes it did start. As far as the vac leak I thought that might be it so I put it a little lean to see if it would drop and it didn't. 've checked all hoses and cleaned the maf as well. So I'm thinking the TPS or AIT is going. Could a bad fuel filter cause bad idling? I wouldn't think so. I ask because the fuel filter hasn't been change to my knowledge. (I'm at 60,XXX)

Anyway back to the original thing. I lowered it down to 600rpm and it darley came down..

one more question why do you want it at 600?

I don't. I want it to idle at a certain spot weather or not thats actually 800 idk and idc, thats where I want it, but I can't seem to get it where I want it. So I tried lowering it even more to see if that would effect it and it barley did.

Acually a vac leak would make your car idle worse not higher. A higher idle in some cases is better then a low idle. But to the main point why would you want your car to idle above 925? To me that doesn't do any thing. You wont get any more WHP out of it. If you want some thing done with the tune get the tuner (whom ever that may be) to change it for you. The porpose of data logging is to do just that....log it and if you need some thnig changed or if some thing is wrong send it to the tuner and let him fix the problem.

It's not for power, the car just sounds better at this idle. In simple terms what can you log and what should I log? I went through it on the xcal3 but it was all gibberish I didn't understand.

What I would do is ask Tom at focus power it seems that (and I could be wrong) this section is for problems with your xcal/preditor...or at least thats the majority of the post that come to this section. You should just get a new tune and the Tuner can bump your idle up acordingly and safely.

ninja, your partly right, a big vac leak would lean the motor and make it run like poop! i know for a fact that a vac leak will cause the idle to go up, it's caused by air leaking in any were between the tb and the head. any air flow that bypasses the idle circuit will cause the idle to rise, the more air the more the idle goes up too much air things will start getting screwy. it happened to me when i put me ported 2000 intake on. i had to pull it back off 3 times to permetex things and make custom gaskets, the only way i knew i had a vac leak was because the idle would hang around 1500-2000 rpm's, but other then that it ran fine. when i sealed everything it went to 600-1000! it is posible that FASTER has a small vac leak causing the idle to go up a little higher than it's supposed to be. i'd check the egr tube and permetex the tb gasket.[nutkick]

My EGR has uhh been disabled by a hack saw.. and some tape..

haha thats the way to mod. i hope it was duct tape. man i watch way to much red green lol

[:D] I never liked the idea of exhaust gasses going back into the intake.

ya, but could it be leakingwere u cut it, or especially were the tube goes into the mani. that's a spot i permed mine.[smackbum]

No It's highly doubtfully. It's taped rather well. Also I believe Tom disables the egr so even if it was open it wouldn't matter. I had my new fuel filter installed yesterday and I have to say that seemed to cure most of my problems. The idle is a lot more steady and it will eventually go just right below the 750 or 800 line. I wish I could rev the car and it would go straight down to there instead of slowly making its way there. I could video tape my cars idle to see what you all think about it.

Actually if I did the math correct the line below RPM is 666.6rpm. Which is quite low.. I'll do more looking into this tomorrow!

I just dont get why you would want your car to idle so low. Keep in mind that the car takes a bit of a hit at times ... like when your AC is on and the compressor kicks on. Also, when you have your defroster on, the compressor kicks on and off as well....not to mention your fans drawing on the alternator. So why would you want to have your car fight harder against that stuff? 900 is the norm for an idle on these cars.

Ninja asked why some people want it higher, like 1k. The reason for that is that some people have all polly engine mounts and it causes the car to vibrate a bit. the 1k idle makes the vibrations a bit more tolerable.

Hm I'll have to try 1K. I don't have A/C I bypassed it.. I want it to idle low because it doesn't shake as bad, and it has a nice deep tone. But if I did my math right 666rpm is to low and I'll raise it today when it gets a little warmer out side.

you can datalog your idle with the xcal3 and there will be no high order math involved.

haha thats the way to mod. i hope it was duct tape. man i watch way to much red green lol

handy man's secret weapon ftw!!!
i miss that show on pbs here. some of his crazy ideas actually work thouhg.
(like the variable wheelbase car)[cheers]

yeah, why are you doing math???

if you are using livelink just click on the parameter that you want to see, it will turn yellow and the y-axis will change to its scale...
