in the config screen, set communication to "Log File"
Thanks a lot! Been trying to figure this out or a while. |

Not sure if this is possible, but might be a neat project/addition to the visual logger. I see a buddy use this on the diesels all the time, pretty handy tool. Ford calls it a cylinder contribution test. Not sure what kind of math it runs to figure this out, guessing it is doing something like reading the speed of the 10 pulses after firing and compares them to each other to give you a relative comparison. Skip to 2:30 https://www.youtube.com/watch?v=xUHiobK0-kECan also use this for what they call a relative compression test. We would basically pull a fuse to keep the motor from firing and crank the starter. Wont give you a number, but can see quickly if there are any flyers. Any thoughts? |

Interesting.
Crank rpms are something like 300-400, which means 5 revolutions per second, times six cylinders is 30 up/down pot motions. Compression happens every other cycle so you have 15 compression events within a second when cranking. To measure relative compression with some clever calculations would require at a minimum 15 samples per second (easy to accomplish) *IF* they are not exactly synchronized so that the pulse count changes for the 10-15s you would be required to crank to get results. Probably 30 samples would make more sense. Seeing that I can log tons of variables at the same time at 20 samples per second, I don't see a problem doing this wit a few variables at 30 samples per second and even higher.
What is the highest anybody logged at to date?
You'd have to log real time tone ring count for last x-amount of time (I think there is a variable that has 20ms resolution for that, so 50 samples per second resolution), current crank angle (probably not a problem), bank deviation from crank angle (also not a problem, not sure if couple degrees of deviation people usually have on the heads would mean anything, but putting it in here for consideration) and map cylinders to crank angles and do some calculations.
Interesting project and absolutely doable.

Ya shit would def be happening fast  I wonder if ford has the routine running on the ecu itself and spitting out the result so it is not limited by the cable. It does shut off if you get the rpm up too high, think he said it was more than a few thou rpm though. It really was a handy way to see misfires or if a cylinder needs some attention. |

Great tool, just can't get it working on my car.
Loaded ecu file. trying to connect, but nothing.
error! Exit code:4. (cause=0x4).
Using COM7
Tried fast-0x 10, slow-0x 11. HM0, HM2 (don't know what these mean). Log speed 56000. Nothing.
Car is ME7 Golf 4 1.8T.
I have blue chinese KKL adapter and original VCDS.

use me7info.exe which coming with me7logger tool to determine connection settings
in my case slow-0xFE working good

Version 1.25 Uploaded
Added support for addition log file types - VCDS, Maestro
Show axis labels for select variables.
Moved logging screen initialization off of logger session thread to minimize logging timeouts while starting a new log.
Many other small additions and bug fixes.

Try logging with the instrument cluster fuse removed. I've had multiple ecus in my jetta. While most logged fine, there were a couple I have run across that just would not log, or would timeout while logging, unless the cluster fuse was pulled. |
