I don't see the MHD Can Bus selection.

Other than the shadow code which I have described above I don't have any readings on the following parameters which my tuner told me to switch to:

-MHD+ WGDC base
-MHD+ Boost
-MHD+ boost target
-EGT pre turbo

I must overlooked something during the flashing procedure, but what?
i dont have access to it right nw, but the mhd options menu should have a drop down that allows you to select the ECA reference.

Problem easily solved

Above parameters only show a value during a pull.
During cruise all show 0.
Advised MHD to update this in the manual.

Sorry this is for Reflex Lite, but must be relevant
Hey.Trying to troubleshoot Reflex Lite and BMP Pi issue. The one bank of Pi is running so rich that i see STFT -34 one one bank. Without Pi enebled STFT is normal. The PI and Reflex is new. Programmed as per instruction. Connected as should. Maybe something went wrong with coding from beginning, now The connection to PC does not work for 3hrs, then after ride connect just fine. I loaded all the files but i am not shure about PATCH part. Do i need to do something with it or no? In initial setup i found patc and it shows Applied. Thanks for Help

Is this happening only when PI is engaged or even during idle/part throttle?

Pi eneblad https://datazap.me/u/ng/pi-enabled-map-4

Pi disabled (dif.map for dme) https://datazap.me/u/ng/pi-disabled?log=0&data=3-21

I have checked LTFT=good.
See also LaMbda recovery in both logs.There is clear that with PI enebled it dumps fuel in one bank.

The stft is not constant but wearing depending on the RPM range

That's really odd variance between banks. I would perhaps double check the injectors are all correct and are same size/flow.

As for the patches, did you patch one of the 2 patches? Should be 2.5bar or 3.5bar depending on the MAP sensor you are using. Also, the map should be the correct one for your injector size.

The map for port injection was provided by Wedge I don't check it in each injector size but they are 750cc injector sizes but they were straight from BMP together with the PI plate rail from Precision race works, yes I patch it only one patch with 3.5 bar sensor which I have.

I think this is not good, harness checked with injectors attached,seems good,the same resistance on all injectors, faulty Reflex Lite or what?

Anyone else having pulsing issues under WOT? I suspect its the ECA voltage freaking out again just like the flex fuel module used to do.

I sporadically will get it acting funny “pulsing” usually happens after I been a complete tool lol with the car reaching “interstate” speeds only…dot dot dot…

I reflash my tune file seems to solve my issue…

Back in the day I had a pulse that wouldn’t go away during wot…ended up being my secondary fuel pump line became disconnected…that took me forever to trace that one down..

Hope that helps good luck an let us know if ya get it sorted.

Its was my hpfp dying. As soon as boost passes 22 psi it surges and then recovers when the hpfp catches up.

Ughh

I did originally have issues... I believe my connection issue was more related to not recognizing there is a timer of sorts you have X amount of time from key on to connect to the tuner software...

I believe in the reflex pdf documents there is a troubleshooting with a more accurate explanation...Sadly my grasp of electrical / software technology has long ago passed me by 🤣...

I am reading the Reflex+ documentation, and it looks like it can send a PWM signal as an output to a 2nd fuel pump? Meaning it isnt just an on/off switch?
