Dataloger findings

[TsiEagleTalon92]

Upon finally getting my PDA hooked up to an old enough computer I was able to check things out with my really poor running eclipse.

The only stored error I had was for my throttle position sensor. I don't know how just this could make my car run like junk all the time.

when I went into the data log section my throttle position was reading at 9-10 and underneath it read 9/ 11 so is this something normal? My air fuel ratio was 18 to 19 and again underneath those two numbers it gave me 18.XXX/19.XXX I am going out on a limb and thinking these are ranges to be in? What should my a/f read at idle?

Well on a wideband oxygen sensor you should be seeing around 14.7:1 afr to 15afr, thats what mitsubishi and most people usually shoot for.
A poorly functioning tps could be a huge deal on a vehicle. That is the source of your accel and decel fuel triggers. It seems that your throttle only shows 10% max? That would mean you have no accel fuel or decel fuel settings. The ecm is most likely in a limp home mode also due to the lack of a throttle signal.

Once my TPS was off by 15% or so (had it maxed the wrong direction of adjustment) and it ran like absolute crap. Definitely get a new one.

I saw it get up to 80% when I had it floored but I wasnt driving it so I don't know the real effect of that is going on. I know 98% I am running rich since I managed to get about 50 miles on a 1/4 of my tank so far.

then again if the single wire sticking out of the top of the throttle body is part of the tps I know I unplugged it at one point because it was loose and then put it back on while the car was running at that time.

Plus since you can rotate it a little bit would this do anything? I have doubts since it has never been moved before. Anyone got a spare for dirt cheap?

[asshanson]

You can pick them up for less than $10, and yea rotating back and forth is bad, it should be tightened down.

If it's loose, that's your problem. Adjust your TPS by watching your datalogger, look for a number close to 0% with the throttle plate closed(duh!) and you should see 100% when you hold the loud pedal to the floor.

[Febo]

On the datalogger site it says its normal to read 10% with your foot off the throttle.

[TsiEagleTalon92]

It's not loose I was saying that it looks like it is able to have a bit of adjustment but if it is supposed to read 10% then it is fine. I ran a multimeter to the TPS on my Eclipse and my Talon and it looks like they bot read the same. So I may think that this is now out of the question.

Is there anybody that would be willing to take a look at this thing by chance? I am running out of ideas and I'm about to go ballistic.
