JB4 as flex fuel?
Hey,
I'm planning on doing a whole bunch of stuff to my n54 in the near future. One of the main things I want to do is run water meth with an e30-50 mix. A Essentially what I'd like to do is use jb4 only as a meth controller/ethanol analyzer/flex fuel and then running a custom tune through MHD. My questions are: Are you able to see ethanol content with the virtual ethanol analyzer through jb4 in order for proper tuning? Does it act similarly to the motiv flex fuel where it adjusts the tune for ethanol content? Is it possible to run the JB4 like mentioned above (ethanol analyzer/meth controller) while on an MHD custom tune? Thanks, Gavin |

I don't think JB4 is capable of dynamically altering engine timing for ethanol content. Probably better off going with MHD for a true flex fuel implementation.
