The EKP checksum value needs to be changed to account for the increased current fault limit then coded. No winkfp needed.

Thanks, I am just having trouble finding what the checksum should be changed to and how it is calculated. It seems everything about BMW checksums on the internet is either on german language forums that google translate has difficuly handling, or has to do with checksums of files to be flashed with winkfp.

Torr, I'm in SA too. Are you apart of Eurotic? I need to do this to my car because I'm getting the EKPS errors; voltage too high and too low.

Yes, I am.
But I do not have a cable that works for your car. I only have the obd cable.

Anyone have any idea how to get e100 working on the F series. I have a 2015 435i and have been running 40% mix well but would like to go more. If I put in 50%, I usually misfire after 100mph of a hard pull

I'm very interested to see what actually ended up happening after running adjusted variables on the EPK module. I was wondering if something like this is still possible without failure in the long-term. I am aware that the EPK modules are prone to ver heating when running a walbro 450. I recently purchased a epkm3 module which happens to be an upgraded module from the epkm2 that overheats. I was wondering if by increasing the values from 50 to 51 on a walbro 450 would that allow someone to run full e85 on a stage 2 pump without failure in the long term? I'm also assuming if this is actually possible you would still need either a hpfp overdrive kit or port injection to run 100% e85 in order for the hpfp to keep up. I'm just curious to see if you can run 100% e85 thru a single walbro 450 without having failure in the long term.

Coding is one thing but physical limits are quite another, if the programming is changed to increase the performance and delivery of the fuel pump this will result in an increased demand for power, is the EKP able to supply 40+ amps ( intermittently or continuously) to the pump? And if so how will this increased load affect its reliability?

The coding will just get rid of the error, if you have an aftermarket LPFP that draws significantly more current than stock like a walboro 525 it will burn out the EKP rapidly. With a walboro 450 which is common in stage 2 LPFP upgrades, these will tend to throw fault codes if the Ekp isn't coded but will tend to take longer to burn out the EKP.

The only solution right now for upgraded single LPFP users is the BPM4 from Torqbyte/EOspeed, unless BMS makes their new prototype lpfp power module able to do load sharing.

Are you sure about this? I have been running a Walbro 450 LPFP without getting a single code.

This is correct.

Yes, some ekps are more sensitive than others and a walboro 450 will not trigger a code. But either way the factory ekp was not designed to run a higher powered lpfp, and head room seems to be non existent based on how ekps are know to fail with stock lpfps.

I will be upgrading to a DIY 3.5 LPFP with my turbo upgrade so an EOS module is in my near future! No point having 500hp worth of fuel pump with 900 hp worth of turbo!
