What's the difference between Pump BEF vs Pump USA BEF? Also are there any more planned updates for JB4 now that MHD has released new features, I noticed the pump maps haven't been revised since 2019. I'm on the fence about ditching JB4 and moving pure flash tune only.

I think it has something to do with the emissions as non US cars dont have the heater DMTL

My cars Australian and I get the 2A13 and 2A18 DMTL shadow codes

Terry I was wondering since you have a US and non US pump gas BEF can you remove the DP error for the non US version?
