Yeah meth is great for keeping IATs down and will help a little with octane. Just use the PUMP flash.

Falied to write packet section 113) (failure to write ECU. Falied to write packet section 536) I don't remember what the 3rd one said. I went to double check that jb4 was in map 0 but now the steering wheel menu for jb4 doesn't work nor will it connect to Bluetooth. On the final attempt I did it with the fuel pump fuse pulled however I didn't give the battery anytime to build back up if it even dropped amperage at all in the first place.
Any ideas?
Random write failures are often due to either current supply or cheap KDcan cables.

Activate the option 4.4 so the JB4 follows the DME boost control.

Just wondering if I copy my modified timing tables from the BMS BB flash over to MHD which are 3 to 4 degrees more up top.

Thanks
It depends on the actual load, there's more to consider. Log first as is.

MHD is a tool to flash DME maps and remap properly all aspects of the engine management (fueling, timing, torque request, boost etc). Flash only MHD maps are available in the app. The jb4 let's you override the DME boost control. The OEM DME map is more suited for OEM power which is why BMS proposes base DME maps to flash with MHD.

Use the BMS e85 map.

Added 12/13/16 maps to the first post. Main change was to add the improved E85 cold start mapping to all E85 maps.

Let me know how the table changes work. It's only ~50 degrees here so I dialed that in and then guessed for colder temps.

Today was -10 F and the car fired up much easier. Before I had to crank 6 to 8 times even with the FUD enabled for e85 cold starts.

Good work Terry!

You just need to purchase the JB4 Only Backend flasher for $79 and download the backend flash files from N54tech .

2fa3 coding missing will get coded away if you do MHD > clear DME codes. As for other codes, do you have 3.5 or 4 bar sensor installed?

You need to setup the jb4 for the 4 bar sensor if the jb4 is controlling boost.

Can you run MHD race BEF on straight 91 or is 93 octane minimum required?
We only have 91 in California.. Also, does the BEF's remove the speed delimiter?

If I'm currently running MHD stage 2 and plane to add JB4 do I need to flash back to stock or can I just flash JB4 BEF flash?

You need to put the JB4 to 4/4 to fully bypass it I believe.

California has E85, mixing a small amount with ACN91 will help get you to 93. At first I was using NOS octane booster from Autozone each tank to allow running a 93 tune - until I made the switch to E85 and I have not looked back.
