RomRaider

Much much better value this time, and with a IAM at 1.
If you can't find anything suspicious in the log i'm happy

Thanks for all the help welaish

you may have engine compartment noise, your car is pulling time on very low rpm and load. anyways. please get me another longer log. with these parameters only. (Remove the 4-bytes value)

AF sensor #1
AF correction #1
AF learning #1
CL/OL Fueling*
Engine load (calculated)
Engine speed
Feedback Knock Correction (1-byte)** (degrees)
Final Fuel base (2-byte)
Fine Learning Knock Correction (1-byte)** (degrees)
Mass Airflow Sensor voltage
Mass Airflow
Throttle opening Angle
Intake air temp
Manifold relative pressure (corrected)

then 1 Wot log from 2500 - redline.

Thanks
Since i'm kinda new to this and English is not my native language i have to ask. What does "pulling time" mean?
And what do you mean with -then 1 Wot log from 2500 - redline.

The car has some minor changes and have never been mapped since then, but i know a guy who will take care of that soon

Pulling timing - decreasing ignition advance (as in knock event).

WOT - wack open throttle - putting pedal to the metal in this case starting at 2500rpm and keeping it there till redline is reached.

Flat out is one thing i'm good at

I am following the instructions in the first post and it appears to be working correctly, but when I interpolate the interpolation button seems to only work intermittently (usually it fails to draw the blue line???). When it does work, the blue line looks good, However when I hit the updsate MAF button, the numbers it plugs into the MAF scale in RomRaider are way off (huge, 15 or 20 digit numbers).

Can you tell me what parameter is being logged on the "Y" (Total correction(%)) when you do the MAF chart in Logger? I can't seem to figure out which value that is. I am thinking I'll just log it and update manually.

Just wanted to add that I noticed MAF scaling on my car getting progressively more negative with increasing MAF voltage, going from ~-1% near idle to about -9% at 2.7v, which is where CL ends (roughly). I then determined that my PCV valve was clogged (vehicle was new to me, only had a tank or two through it at that time) and, since replacing the PCV, the downward slope of my MAF scale is no longer present. This is something that I had not experienced before and wouldn't necessarily have thought of as contributing to a bad MAF scale, so wanted to throw it out there in case others noticed this pattern when beginning MAF scaling.
