Lap3 with JB4 for Meth & Logging

[Valkyriemedic]

Lap 3 2.5+ ECU and TCU on the way! Currently running JB4 with Fuel Wires / EWG / WMI on Map 7 and E35 fuel mix along with Tork Stage 1 TCU. Plan on keeping the JB4 for WMI and Logging as long as I don't run into any issues. I know I need to start by placing the JB4 on Map 0 and Turning on Bits 0 (disable fuel control), 5 (disable EWG) and 6 (Flash tune installed). For WMI I know I need to set Meth Trigger to 1 (enable in all Maps). Questions... 1) Will WMI behave the same as in Map 7 this way (Flow start / safety, etc)? 2) Should I leave all other Meth settings the same. I have just been running 50/50 Meth blend but will be going up to 80-85% with the Lap 3 (was going to with the JB4, just never did). If wondering..no issues with the JB4 (had to make some adjustments off default initially) and happy with it for the past 2-3 years. Just reading all the comments regarding the smoothness and power of the Lap 3, so going to see. I have seen the post where some have had to switch to Map 8 if using Lap3 flash with JB4 due to boost issues. Thanks for any input!

^^^Wondering the same.

In addition, what is the difference/advantage between the LAP Stage 4 WMI progressive injection vs the JB4?

Not quite sure what the question is here? But for flash maps start on map0, and then log, and we can evaluate from there. Different flash maps benefit from having the JB4 do different things. With lap3 2.5 often you use the JB4 to reduce boost as it tends to have an over boost tendency for some for example. But we can determine that from the map0 log.

How you turn on meth injection on map 0 if on a ECU tune? Do you go on the ethanol setup and turn Bit 7 on?

No, on the "User Adjustment Settings page", set "Meth Trigger Mode" to 1.
There are no safety's though, for example if meth stops flowing, etc.

So would it be better to run map 7 on lap 3 ECU?

No, you need to run map0 with an ECU, or they will try to interfere with each other.
I would email terry@burgertuning.com
There is a whole formula for this.
