BMS HPFP

Anyone buy Burger's fuel pump? I see two options here and I'm not sure how to decide:

HPFP Upgrade with BMS CANflex Kit = This kit contains the HPFP upgrade and adds a flex fuel kit to your selection. This variant integrates the new BMS CANflex LED ECA that includes both a digital display box to monitor ethanol mixtures as well as a voltage output for those running a JB4. Note the display box is not weather proof and must be routed either inside the glove box or under a cover in the engine bay for protection from the elements. This kit also supports CANbus operation and our 10bar low fuel pressure sensor kit making it ideal for future expansion.

HPFP Upgrade with Fuel-It! Bluetooth Kit = This kit contains the HPFP upgrade and adds a flex fuel kit to your selection. This variant utilizes the original flex fuel kit which includes both Bluetooth for the free Fuel-It! app and a voltage output for those running a JB4. This compact unit is completely weatherproof and does not require any special routing.

I just installed the HPFP with CANflex. it was kind of easy but also im having complications. From my understanding the canflex gives you digital read outs with jb4 integrated logging. The fuel it is the old school previous that you have to use an app for. The CANflex is nice a little more parts a little more tracking more visable small variation from jb4 to the digital read out, like 1 e rating difference.

my problem now im facing is a high fuel trim, jb4 reads 26-27 AFR is flux 14.3-14.7 at idle. Says my ethanol is 5 when i put 4.5 gallons on top of a 3/4 tank 93 over a month ago now down to just over half. I should still have a e20. Idk why its giving me a CEL in map 3 and then i run map 1 and the CEL clears. the trims remain high and the AFR still lean even at 1900 rpm. HP fuel is reading 4 on psi.
