?? Is it a custom tune or a preloaded sct tune?

 

custom[nutkick], i told them my mods, they loaded the tune on the x3 before they shipped it. the x3 doesn't have the pre-load tunes anymore bty. [thumb]

 

Try having them add ISC air during crank. Worked for me when I had longer than normal crank times.


but 2 minutes is a very long time to be cranking, there are bigger problems here.

 

not 2 mins constant i crank 3 sec., then let it stop then another 3-6 sec... for 40 sec. to almost 2 min...[unsure] then the next time it will start the first 5 sec. i don't think it's the car, it start fine with the stock tune! unless something is wrong with the car that the tune has a problem with?

 

Yeah sounds like my suggestion may fix the problem. When I first loaded my tune I had a similar issue it was sort of choking off when I started it, so I added ISC air at crank and the problem disappeared.

 

you can check if this is the problem by slightly opening the throttle after you turn the key to on but before you actually start the car.

 

dude!!!!! [clap]thet's what i have to do to get it to start the times it will start, i just thought that had to do with me having 2/3's of my idle circuit taped off temporarily to bring the idle down do to a bad controlle valve. but ya, i have to press the gas a little for it to start. but it only work every other time.[screwy]

 

Dude this is why

is the fuel smoke something of concern? an does anyone know what might cause it to no start right away? it's turns over like it's not getting spark but then it starts after a while and runs good. it's not throwing a code, but i think my idle valve is bad cause it wants to idle at 1500-2200. so i taped off 2 of the 3 holes on the tb idle circuit for now. it bought it down to 1000. but i hate it not starting![rant]

you need to uncover those holes, and then get your tuner to work out your idle issues in the tune.

i think it's set at 800 rpm's already. the idle went up like a week before i tuned it
i think it might be the control valve. there $75 so i taped it for now cause i don't want it idling that high while i'm driving around.[idea]

 

If you want it fixed 100% youre going to have to un-tape the idleholes and talk to your tuner about the high idle.

 

ok well if its bad on your old tune then its the valve... you know your problem no need for this thread really...

 

i think i know the problem of the high idle. but i'm at a loss to why my car won't start with the sct tune, and starts fine with the stock tune.[scratch] but i'll try pulling the tape. it just hit me what ISC air is[slap] the valve may or may not be bad if it is bad though u can't work with idle air on the tune. i didn't think of the idle being related to the no start that's why i started this thread, i thought there was something more complex or technical causing my problem, but if u had a similar problem and that fixed it i'm sure that's probably the cause of my trouble [thumb] thanks for your help!

 

actually YOU cant work with it on the tune no matter what, but your tuner can!

The valve controls how much air gets in during cranking as well as during idle, coasting, and on some tunes its even open during part and full throttle.

Get a new valve, remove that tape, and try loading your tune again. [thumb]

 

i get payed Friday, i'm planning on getting it then. i'll post the outcome...[wave]

 

I had the IAC valve get funky on my svtc. Took it off and hosed it down with brake kleen. Fixed my problem and cost me nothing. Maybe worth a try?

 

thank's gocart, i bet it would work, but it's the second used valve i've went with and i really want to go with a brand new one now. new cv's have a 2 year warranty, so i'm covered for 2 years of freebies if the first one don't work. i appreciate the help though![clap][wave][]

 

i took off the tape and changed out the idle control valve, it still want's to idle high.[scratch] that's $75 wasted! but it did give me a chance to put in the sending unit for my oil pressure gauge.[nutkick] i read a thread about the maf causing the idle to do funny things. so i'm going to get some maf cleaner asap. it makes sense to me because i had water get sucked into my motor, the cold air tube worked like a straw when i drove threw deep road puddle. that could of fouled it[idea]

 

also try unplugging your negative battery cable for 30 minutes so it re-learns idle strategy.

 

sweet, thanks dude, i'll do that tomarrow![clap] still may get the cleaner too, it won't hurt.

 

i disconnected the neg cable, it dropped for a while but was eradic. so i cleaned the maf, but the idle was still all over the place, from 500 to 2200. the idle seemed to be different every time i pressed on the clutch, but it was still better then a constant 2000+. today i cleaned the maf again and disconnected the neg cable after. i took it on a beer run and the idle didn't shoot up passed 1400 but it didn't hold sill either.[scratch] i'm doing a log tomorrow, hopefully that will shed some light on it.

 

datalog throttle position relative to closed, drive around for 30-60 seconds, and post the results.

 

btw, also log other useful stuff like rpm, stft, ...

one that would be really good to look at is throttle mode flag

 

though it fought me tooth and nail, i managed to get a good log saved of a little idle and a hard excel. mines a stick so shift is na. what's bwt? i got rpm, frp, fpdc, load, short term, and some other things that didn't record.[scratch] but i have no idea how get the log from live link to here.[?|] how did u get yours on the open loop thread?

 

btw = by the way

dont log fuel rail pressure. you want to log pressure drop across injectors.

I have been taking screenshots (print screen button) open mspaint, ctrl-v, save as jpeg, post to photobucket, post here.

also try to log values in caps, they update faster. Plus a lot of the lowercase ones arent actually being recorded.

 

i was wondering why i couldn't find btw in the list of parameters. [clap] i pressed print screen a hundred times and my laptop does nothing at all.[rant] so i guess i can't post it.

 

it doesnt do anything that you can see. it copies the screen to the clipboard.

you have to open paint and paste the image (ctrl-v).

 

open it from were, if i can't see it i don't know were it is.[paranoid]

 

1. hold down the window key, then press r and let both go

2. type in mspaint

3. click ok

4. hold down Ctrl and press v then let both go

5. save the picture as a .jpeg (be sure to change the dropdown where it says .bmp)
