Flashing order!

This might be a known fact but today I just discovered that you need to flash your TCU first then your EC you maybe I have just always been wrong in the head but I was constantly getting issues with second gear and just a very jittery shift nothing felt right I played with it a lot on SHP to make the transmission feel right but never had any success then I finally started messing around with the order of flashing and that's when I found the issue

P.S. I am going to feel really dumb if everybody knows they should do it in this order but I just feel like it should be known

It may be different for your car but for mine it got rid of a lot of shifting issues by flashing with XHP first then BM3 2nd

Yeah that's what I thought.. I haven't seen anyone having this issue but this has fixed it so I figure if anyone else is having odd shifts it might not be a bad idea just to suggest changing the order

I was actually going to pose a question about this soon because i just removed MHD to go in for service, and i plan to get XHP for the first time afterwards.

When you flash MHD you have the option to select if you have the XHP flash enabled already. Because of that, i was thinking about flashing XHP first, then flashing MHD. I suppose you could also flash MHD and not select the XHP option, then install XHP, then reflash a MHD map by just changing that selection for having XHP installed... Now I'm not sure.

Can anyone who has flashed both XHP and MHD comment on the order they did things?
