I'm not sure where I got it, but I have Haltech e6k version 707 on my computer. I believe the only version availible for download from Haltech is 634.

Does 707 do anything I need or should I stick with 634.

Thanks

DOWNLOAD AT YOUR OWN RISK!!

This was never publicly released, so there is the slight possibility that you might encounter a few bugs. The only benefits to using v7.17 on K is dual maps.

 

There's also the 6.34u version for datalogging and viewing wideband values in true afr's.
