Just connected up a Data Logger and i've got ?'s

K_Mans_TSI · Apr 10, 2002

2 things are what caught my eye.

1. My TPS was reading at most 92%
2. my timing advance went to 33 degrees at 2k rpms but then slowly went down to 7.5 degrees at WOT (no matter what boost i ran we tried it from 12 to 20lbs same thing)

Is that second one normal for my car?

K_Mans_TSI · Apr 10, 2002

how bout the throttle % is that normal and considered open all the way?

eyebrowski · Apr 10, 2002

im pretty sure your throttle % should at least be around 98-99%

The throttle percent is normal. Some cars record higher than 95% and the rest record less. I have 96% shown on the datalogger during WOT. Maybe you can try to adjust the throttle position sensor or maybe your floor carpet prevents you from really WOT or your cable is loosen. But if you've checked everything and they seem normal, then I think 92% is normal for your car.

The timing should drop first at lower RPM when you WOT and slowly increase up to 17 - 25 degree depends on your set up. i think you either get serious knock or something wrong with the setup. Did you buy the pocketlogger? If yes, email mike and he will help you out.

ya I only get 95-96% and thats with me manualy opening it on the throttle body. I though I was suppose to see 100%.

K_Mans_TSI · Apr 11, 2002

that was at 12lbs the first run and i saw that timing setup so i dropped it to 10lbs and it did the same...went to 20lbs by accident, same reading.) the only thing i can think it is is the 1g CAS on the 2g (95 with the inverted polarity signal) I used a standard ODB2 scanner for chryslers that my friend has.

one more thing, i was seeing those timing readings even before boost was building...if i floored it in 5th at 10mph i saw that timing reading of +7.5

What's your timming like between 6500 thorugh 7000rpm? You might have a bad knock sensor. Reset the ecu and do another run. Just in case it's in limp mode.

K_Mans_TSI · Apr 11, 2002

Well here's what it was.. if i was ON WOT at those rpms +7.5 if i was on 1/2 throttle at those rpms +18.5 if i was off the throttle at those rpms +33.5

K_Mans_TSI · Apr 11, 2002

stupid question but where is the knock sensor located if it turns out to be bad?

nano · Apr 11, 2002

On a 1g at least it's on the back side of the engine block. Bolted on. Reset the ecu and see if anything changes.

K_Mans_TSI · Apr 11, 2002

i have the 2g knock sensor then if it's what i think you're talkin about on the 1g block...i'll try resetting the computer but if that doesn't help what do u think is going on?

trbotsi · Apr 12, 2002

Something definately odd is going on with your car. What you want is your timing to advance all to way up to 20-25 or whatever your car should get. What's your base timing set at?

K_Mans_TSI · Apr 12, 2002

I took it to my buddies shop and he asked me if i was feeling any performance decrease, i said not that i knew of...he said if it was the knock sensor it would be acting funny in the morning or at idle and stuff and it's not. my base timing is at +6.5 we're gonna do another run with the car here soon, do u think the 1g CAS on the 95 w/ inverted signal is causeing a problem....

K_Mans_TSI · Apr 16, 2002

Well i tried it again today, TP sensor now reading 100 YEAH! but the timing was still messed up. so i disconnected the battery for 4 hours at work today to be safe. then i turned the boost controller all the way down to 9lbs (or whatever the lowest is) drove it for 3 miles and it felt strong even for that psi. i slowly raised it to 15....wow it's pulling good again, totally destroyed a probe gt that ddint' know what it was messing with...so i took it back to 17 OMG it put me back in the seat again!! woooooooo my car is fixed

i'm gonna run the logger on it tomorrow and see what the timing is reading jsut to be sure.
