Default MHD stage 2+ - 08-22-2020, 10:49 AM

Hey guys just a quick question. So, I have been running the JB4 with the MHD BEF for a while now. I feel like there could be some improvements. I was wondering if I did the MHD stage 2+, do I just leave the JB4 settings the same as the BEF and just upload the stage 2+ with the JB4 disconnected and then connect the JB4 back after the flash?

I am PWG, FBO, running e20-e25 mix on my car. I have definitely felt a difference with the BEF compared to just JB4 on map 5. Ran a best of 12.7 at 109mph with the BEF. I think I was only able to hit 13.2 at best on the JB4 alone. Crap all season tires and I could not get the car out of the hole enough even after lowering tire pressures. Couldn't get under a 1.9 60"

Goal is to 12.5 on the same tires until next summer after the new wheel and tire combo is in. Hope for 11's next year after a fuel pump upgrade, e50 mix and custom tune.

You won't gain with an MHD flash instead of a BEF. Focus on air (turbo) and fuel (hpfp and lpfp). Air + fuel = power.

The MHD has the ability to modify the timing table(s) according to your typical fuel of choice. The stage 2 might be too spicy for your day 2 day driving.

Does your timing look good with map 5? If so a custom map 6 could eek out some more boost.

With pwg you could probably run more ethanol than e25.
