Ssangyong Kyron 6AT cruise control problem

Postby Vahmurka » Thu Jan 31, 2013 2:36 am

Hi guys!

I have an interesting problem with my ECU and cruise control. On stock HCD38A01 firmware everything is working just fine, but on update HCD38A06 one cruise control always shutts down when AT reaches 6th gear. Hard googling, i found that new firmware is possibly designed for 5AT transmission. The reason to install it is much softer engine running and outstanding startup improovment in cold weather conditions.

What if i create a patch 05->06 for new firmware? Is it bad idea? :oops:
I suspect 3 addresses
Comparing files HCD38A01_D145_AT_ORI_full.bin and HCD38A06_D100_AT_ORI_FULL.BIN
