I'm running RICH and I'm affraid of messing up my engine. This would mean losing my job and all the other fun stuff involved with blowing up ones car LOL I've posted my log please tell me what to do with this. All of my mods are listed on my profile.

id say its your wideband. if you look at 369.3 seconds, your wideband is maxed out at full rich, but your running 600cc/min at 700 hz and your front o2 sensor is reading .88 volts. your injectors are at 23%, none of your fuel trims are saying your that rich. I mean none of this is dead accurate, but your wideband is maxed out on the rich reading while everything else looks like its in the right ball park.

pull your spark plugs out and post a picture of them. Don't forget anti seize when you put them back in. If it really is running that rich, you'll know. If it was running that rich, you'd see knock though too, and you'd also smell gas even through the cat, and your car would run like shit and get 10 miles per gallon.

Id say either your lc-1 is programmed wrong (I've had them just revert to default settings on me before) or possibly your sensor went bad. I highly doubt your running that rich.

btw, things you totally don't need to be logging:
clutch switch
power steering load
mpg
torque
hp
load factor
idle switch
a/c
a/t d
tps volts
keystart
boost est (if you haven't properly calibrated it)
isc
many others

So you think the LC1 reverted back to default. The sensor is brand new and I've done 2 free air calibrations, i guess i'll try and program it again. I hope I don't have to buy another sensor. I was told I need to mess with my MAF comp sliders also.
 
Forget about your WB being off, why don't you tune your idle first and stay off the throttle until its ready for it.

Follow ECMLink's demo videos, just because you've got v2 most, if not all, things still apply since you've got v3 software. Once you get FT's where they need to be then you can worry about why your WB isn't working correctly...

Initial Setup
Fuel Trims

Ah man I was looking for that stuff, thank you, I'm just worried that I'm going to mess something up.
 
Pay Kris to tune it then, he's more than happy to fill his wallet with more cash I'm sure.

:dsm:

I am far beyond broke, I've been looking for a second job for 3 months now so I can get this stuff done. I've been temped to sell her just to stop the $30 here $200 there and so on a so fourth ... I've been temped to trade for this built 240 for a while now...but it needs to have a turbo installed and tuned as well LOL But I just really want this car to get to the point where I just have to maintane it and then if I want to throw a bigger turbo or upgrade something I will but the car it's self is demanding upgrades that I can't get to quickly LOL
 
Good things come to Those who wait brother

ok....So I wait and my engine blows while I'm waiting how is this going to help me .... no money a kid ...this is my daily driver ....child support, Student loads,one job and being garneshed, and paying too much for everything. Not to mention the lack of help on DSMlink forum. So with all of that try getting a loan and making rent as well as keeping the wife happy which is next to impossible.

theres always a way man, if i was you, i would find a way to get around temporarily till you can save up to pay kris to fix it. until then you'll have to do what u can to get by.

I'm just going to go home and sit in my car and try to tune it, whatever happens I hope it's better than where I am now.
 
dam man, i dont think thats a good idea, i hope you dont break anything.

I really have no choice man, Im not going to like do pulls I'm just going to try and get a good even number with the A/F, I'm going to reprogram that as well (LC1)
 
guys guys guys,... stop fighting.....

you wanna soooodddaaaa??????


I think your worried too much about your wideband reading. I'm pretty sure its wrong. I'd follow all the tuning procedures for the 50hz-400hz range and tune that as best you can. You'll learn a lot about the short term and long term fuel trims and how your ecu works. Also, because those load ranges are so low it will be really hard to blow up your engine. I'd be REALLY impressed if you managed to blow your engine up while tuning the idle. I've got faith in ya man. you don't need a wideband for that though. Maybe before you start tuning pull a spark plug and see if your actually running rich, ### you might be, even though I doubt it.

I wouldn't be surprised if reprograming your lc-1 gets you 90% of the way there. I'd like to point out that 7.3:1 is just the lowest your wideband can display on dsmlink, that doesn't mean thats the value it was reading/producing. When you have the senario you have (max rich to max lean all the time) its a good indication that something with the wideband isn't working, since your car wouldn't exactly run very well like that.

How many miles do you get on a tank? If its over 200 your not running that rich. Like I said, I'm pretty sure you'd notice if you were actually running that rich. There would be knock to go with it too, and extreme power loss, hesitations, stalling a LOT.


And also, the dsmlink forums are extremely helpful, just daunting with information. Its impossible to present that much information to someone with no experience without it appearing daunting. Just start reading somewhere, and then read elsewhere, and then re-read what you read at first, and keep doing that until things start clicking and you can start to see a bigger picture.
 
Ah man, that makes me feel a little better with the info you gave me. i did reprogram the LC1 so i will know if it's off tomorrow but I'm bringing the laptop with me to work so I can log. I also resolved the Throttle body issue, it was a combo of things, TPS, throttle cable, idle switch all solved through link. idle tune eh I was going to do it but I figured i would see what my log looks like tomorrow and go from there.
 
I agree with tstkl. I was in you boat when I bought my car two years ago. I never tuned with any programmable computer. But I read and read, asked for help, tried the tune my self and got it pretty close. Its not professionally done but I don't get gbad mpg and I'm holding steady at 20 psi. Not to discourage you but a dsm will do that to a person. You have to have patience and read. My wife complains all the time about me reading about topics on my car. My answer to her is its either that or spending hundreds on a pro to do it. She shuts up quickly LOL. So again bro. PATIENCE. It's taking me a year just to get a fuel pump and afpr to run e85. Lol. Those are the cheap parts LOL.

Yeah you guys are right, it's just starting to get to me a little I would like to tune and be at like 330hp for now and then move up from there. The tuning to get to that point is as tstkl "daunting" but I hope i can just get there without killing anything LOL
 
im sure Kris could give you a few pointers on how to do that stuff, that way your not just doing stuff your unsure of.
 
I'm sure you've heard this before but I think it might need mentioning.
Cheap. Reliable. Fast.​
Pick two.

If you want a 320whp DSM its not going to be reliable unless you spend some money, not necessarily on mods but maintenance. Keep that in mind as you budget for all of this, maintenance before mods or you'll end up broke and your DSM will be up on jackstands for awhile. The more your read through the forums and learn on your own the less money you'll spend having someone else do the work. If I had paid for labor costs for all the maintenance, as well as mods, over the last 6 years my car wouldn't have nearly as much done to it because I couldn't afford it.

:dsm:
 
Corey, if you had to pay someone for the maintenance your car has seen... you would not have any mods LOL

I'm trying to keep up but all this stuff...I do have the majority of the support mods... I just want to get to the point where all I'm doing is maintaning LOL all I'm missing is a fpr a FMIC and a few gauges. all the other stuff I have is quality stuff
 
calm down get your car running right and stop modding. be happy it turns on once or twice a day if your lucky. make a little jar for parts when your ready buy it. non of us just woke up and spent 4-5 grand all in one day. it took the majority of us years to aquier the parts we have.
Baby steps to the fmic... baby steps to the afpr... so on and so on.:applause:
 
Not true.... Corey woke up one day and said, you know im going to drop 4k on a transmission LOL

But yes, you have to take it little steps at a time... Go for maintanence to begin with, get all that worked out... and then toss on a part here or there....

Like me, i still dont have a MBC, ive been running off of waste gate pressure since i bought my car almost 2 years ago(20psi at the time was due to bad WG arm....LOL but still wastegate pressure)
