My first datalog .....
I am still sort of new to this and am learning alot fast. Just got my first datalog using Tunerpro. Mods listed in sig. Car throws a few codes but runs. I wonder if someone could take a glance at my logs and see if they pickup anything I dont see. I plan on getting a tune very soon for sure...
Here is the file
Here is what i see in the file:
Here is the file
Here is what i see in the file:
- My coolant sensor is obviously not working.
- BLMs indicate car is running rich (car still on stock regulator with fms 24lb injectors)
- TPS Voltage may be a little high for idle

First and foremost - fix (or plug in 
) the CTS. The ECM uses MANY formulas based on coolant temp. This is why it is running rich at idle in open loop - the ECM "thinks" the engine is super cold and is programmed to add fuel accordingly. Once it enters closed loop, the ECM is correcting this by taking away fuel (118 BLM).
TPS voltage at idle of .61 is a little high, but not off the charts.
I wouldn't make any adjustments until the CTS is fixed.

Based on the 02 voltage, you're not getting into closed loop in this data file. The BLM of 118 shown for cell 0 must be an old stored value.
The O2 voltage needs to go above 700 mv or below 300 mv for the O2 sensor to go ready.
Why not post the log file itself (*.adl) rather than just the *.csv export?
