135i JB4 BEF I8A0S cruise control fix

[MrBlah]

Anyone fixed cruise control for a 135 using the JB4 backend flash maps? This tune is quite a bit smoother than when I apply all the changes to my original tune with tuner pro. Short of going through all the thousands of changes in Winols does anyone know where to look or done this?

For those that do not know, the BEF maps were done off a 335i bin, 135i cruise control does not work on many cars on MSD80 I8A0S mine included, same problem with some of the other free bin files floating around the internet...

I know how to apply the changes to my stock map with tuner pro xdf, but it is not as smooth in the 2400-3200 rpm range where highway cruising is done.

I have the damos for winols and can go map by map but if anyone else has fixed this issue it'll save me a ton of time!

What's not smooth about your original tune with the changes applied?

A method to determine the hidden differences between the two is to use the comparison tool (Ctrl T) against each other (BEF and Edited stock). You'll know then if there are any changes to maps or bits that are not defined in the xdf.

The bef map started to do the same rich spot at 2900 so no gain, I'm back on my bin with the mhd bef xdf defines applied to it. With both maps you can see the trims drop hard at 2900 I'm not sure why I did not see anything obvious like fuel pressure or timing changes

only does it at low load
