Upgrade EKPM?

todd20 · 06-04-2021, 09:32 PM

Hello anyone here upgrade their fuel pump and have to upgrade the EPKM too?

My tuner Cary told me I should but after doing some research no one seems to know anything about this. Do I need to upgrade this? Also what Ekpm do I buy?

I have a new stage 4 LPFP from precision racework coming soon because my stock lpfp was giving me issues on my e85 tune.

Call Torqbyte, these are the only guys that can do it. Had their fuel pump controller (PM4) on my Audi and worked flawlessly.

Sounds like the S55 is being confused with an N54 or N55. There is no need to code or replace the EKP fuel control module on the S55.

I'm running PR's Stage 4 fuel upgrade with no issues.

Upgrading the EKP would be the most ideal solution for a single pump, oe controlled solution with a Torqbyte PM5. I know Bend Calibration has been working with EOS/Torqbyte to bring a solution to market.

Sucks since I can't use my VAG one on the M but have been keeping an eye on this;

Keep an eye out for the EOS PM5
