Hi all, I picked up a ADSL cable from moates and installed it along with the .ads file I would need to data log. PS Data logging rocks!!

ADS file:
updated 1227730.ads (Its a bit strange but in the info section its 90, 91 camaro) I don't know if that is normal that is doesn't say 92 as well.

Ok, so I hooked it all up and had the car parked for about 8 minutes or so. The BLM is showing 131 which I believe is above the the norm of 128. I then started checking to see what readings I was getting with the other sensors and I notices NO reading from my TPS (throttle position sensor).

Does this mean my TPS is shot? If that is the case wouldn't the ECM throw a code saying the TPS is bad?

 

Hi all, Just wanted to see if anyone out there could give me there thoughts on my data file. I actually noticed that the Throttle Postion did have voltage and the TPS% went up when I hit the accelerator. My BLM seems to always get to 131 (should be 128 from what I was told) once the car is warmed up. This log is about 8min with the car parked.

Again I am trying to figure out why my CO emissions where a little bit above what they were suppose to be. Anyone see anything odd?

Here is the ADL file (my saved log file) zipped up:

A BLM of 128 means the ECM is calculating the fuel requirements exactly right. If it misses on the calculation, the BLM raises above 128 (to add fuel) or drops below 128 (to cut fuel). A BLM of 131 simply means the ECM is finding it necessary to add 2.3% extra fuel over what it calculates. That is not an unusual condition. Anything within +/- 5% (122-135) on the BLM's is generally not a problem. When you exceed those limits, you have to start looking for a problem.... but not at 131.

You file appears to be in .adl format? Does your scan software offer the option of exporting the file in .csv format? That way it can be opened with a program like Excel.

 

Injuneer thanks for the reply. Hmm puzzling situation I guess then. I was thinking that since I was at 131 when the car was warm it was a dead give away something was wrong, but what you said makes sense.

Here is the TunerPro exported csv file.
