There is a map, KFNWEG, which allows the fuel to cut back in depending on gear, coolant temp, and gear. The gear may be applicable to tiptronic cars only, i'm not sure if the ecu knows current gear with a manual box.
The map is not enabled by default on our cars, to enable you need to set the codeword CWSAWE to 1. I do not have an AFR gauge in my car at the moment, so can't try it - unless i get pops and crackles on overrun - then i'll know!
Can somebody try and let me know? I've attached an Mbox XDF with the codeword and map defined.

 Rick, you've invented chav mode.... Oh, and don't do this if you have cats on your car.

I am not sure, but I think 6sp S4s know what gear they are in by matching RPM readings to vehicle speed and doing a backward calculation. The car knows only whether it is in gear or not by means of a switch.
Here is who I know. When logging with ECUx I pressed the clutch after a FATS run and let the revs drop while I was coasting at high speed with the car still in 3rd gear. When reviewing the logs later, I think, I noticed that the gear data was jumping to a higher gear progressively as the revs dropped.
I could be wrong.

Manual transmission cars know what gear they are in based on engine speed and vehicle speed.

You could simply look at injection time to see if the car is fueling.
I'm going to flash a file tonight and try this.

Does anyone know where the codeword "CWSAWE" is in an 032HN file, sw0001?
In 0002 its at 1126B, but cannot tie up with the sw0001.
WinOLS doesn't know, and if I keep it in the same place it says the value is 12 (should be 1, 0)..

would anyone be able to help confirm if I have found CWSAWE in this file? I believe I have it on the right at 1B6D5 but there are minor variations in the quantities surrounding that offset. I am comparing from the known offset in the 1.8t 225 BAM ols.

Well, after an hour, I give up lol! Found the address in WinOls, made the change from 0 to 1 and saved the file. Couldn't find this saved file anywhere. After searching Google, it appears you can't actually use the edited MAPs created with the demo version.  On to TunerPro, bit harder to find the address, but found it in the end. Made the change, and compared the new saved MAP with the original. Only one difference (the one I made), thought brilliant! Saved the file with a big grin on my face. Checked the new file with me7check, found 5 checksum errors! Does this sound right? Can a very simple edit of a 0 to a 1 make this many errors? |
