I finally got the lap top up and running with the software. Here are the results. I assume most are normal. Please let me know the ones that are out of wack and if i need to fix, replace or clean something. This is after 10 minutes with the car in closed loop. At idle, RPM 550-575. desired rpm 550, IAC 53, MAP .421, BAR .956, Start temp 32 deg F (78 degrees outside), coolant temp 188 deg F, MAF 123 deg F, Spark advance 18-21 and goes to 40-46 if i rev the engine to 1500 rpm's, airflow 6-7, integrator L & R both 131, BLM content 129 Blm cell#16, Throttle position TPS scaled 0, Volts 0.61, Coolant temp 86 volts 3.29, Map bar scaled .345 volts 1.56, I have read many posts and it hards to say weather these are normal but i would guess the MAF at 123 deg F is a problem. The scan show 2 different coolant temps and i don't know if there are 2 different sensors or what.

 

RPM 550-575. desired rpm 550, - stock programming for an A4, in gear.

IAC 53 - On the high side.... usually wan't it between 20-40, but who knows how your S/C affect this?

MAP .421 -You have reported two values for MAP.... below you indicate MAP = .345, volt 1.56. An NA engine with a stock cam would show .345 An engine with a blower might show something else.

BAR .956 - What is your altitude, where you live? At sea level, barometric pressure is more like 100-103 kPa, which would convert to 1.00 - 1.03 in the units FreeScan is using.

Start temp 32 deg F (78 degrees outside) - Check your coolant temp sensor accuracy.

coolant temp 188 deg F - You don't have two coolant temp sensors. Below you report coolant temp sensor is "86".... appears that is the reading in degC. 86degC = 187degF

MAF 123 deg F - You read something wrong. I suspect this is actually labeled "MAT", which is the inlet air temp, probably indicating a heat soaked IAT sensor.

Spark advance 18-21 and goes to 40-46 if i rev the engine to 1500 rpm's, - Normal

airflow 6-7 - Normal grams/sec at idle

integrator L & R both 131, BLM content 129 Blm cell#16 - Cell 16 is the "idle" cell". BLM's at 129 are good. Quoting a single value for the integrator is pretty much meaning less. The INT's are cycling up and down rapidly, above and below 128, in response to the O2 sensor swings. You need to look at the INT's over a pong period of time, and they should average 128. If they aren't averaging 128, the PCM will alter the BLM for that bank to get them bask to 128 average.

Throttle position TPS scaled 0, Volts 0.61 - Normal TPS voltage for a stocker.

Coolant temp 86 volts 3.29 - See comment above.

Map bar scaled .345 volts 1.56 - See comment above.

Most of this could have been figured out with my online scanner guide.

 

barometric pressure reads wrong i think. I live at 2461 ft so does this mean the sensor should be replaced? BAR .956

 

At sea level you should get 1 bar in theory..

Above sea level, you should get less...

 

Your MAP sensor is reading the barometric pressure correctly, for 2,500-ft elevation. Standard barometer at that elevation would be about 94 kPa, but its normal for the pressure to vary with the weather.

Again, this is all covered in my writeup.

The write up is great but remembering it and fulling understanding it is harder to do. I have used it several times but when i have a scanner with 20+ different things it would take me days to break it down. I appreciate the help and eventually i will know it by heart but right now i only know enough to be confused. I get each thing by itself but when you put it all together it over loads my brain. Thanks and i know 10 times i did before using this site and never had the ***** to try hard install like i am doing and plan to do. You guys are like having a dad for a mechanic that is always there 24 hours a day.
