One could only wish lol, I really want to win that fuel pump too, would save me some money to say the least!Hoping this becomes available in time after I win that Stage 2 LPFP. *Fingers Crossed* hahahaha
This is mainly for @jyamona
I have seen lately odd behaviour with fuel scalars. It feels like it's not responding to those changes I have made in scalar tables. It seems to me that the DME is adapting quite a lot even if I make quite big changes. So can you confirm that this sort of daptation is really happening because if it does it will be quite difficult to have a proper tune with your flex fuel system.
In addition I see this behaviour more when I'm using scaled MAP conversion table with n20 MAP sensor.
I think @V8bait has witnessed this behaviour also in the past with some cars?? This also happens with pump gas and I have to use quite big scalar values even with pump gas to not max out with STFT. LTFT I can get between +/- 5%.

FWIW - I've also noticed my scalars needing to be increased first to 1.05, then to 1.10 l, over the last five years on pump 93 in order to keep STFTs < 20. Not sure why, but my guess would either be the injectors and/or the O2 sensors getting old, all of which I believe are original with the car since 2008.
It's a VVE OS the car uses, you shouldn't use a static/simple scalar with mods that change airflow or else you'll have this issue if you don't reset adaptations occasionally. Try using the 3D scalar to account for changes with mods like intake/exhaust/turbos etc which free up power more in certain parts of the table and less in others. Also, some of the newer table mods modify the VE and load calculations, and MAP sensor scaling definitely changes things at certain loads. Gotta reflect these things right in the scalar.
The last post of his that I saw was that the coding/porting is done and they are working on intellectual property protection with MHD.
was on a forum hiatus for a little but I'm good now.. would absolutely love an to see an update of the progress
kind of put off getting an upgraded pump and running e altogether until I saw where this went so I'm hoping the eta is right around the corner

Same. Although I thought it was right around the corner when they released details months ago.
