Nice results Terry! I wonder when full bolt on will start including turbo inlets in that reference Some day in the future I suppose

Even the old Low Load AT Pump Flash map?

Dragged our tune only N54 development car out for a little dyno testing today.

The test car is a 2008 135i automatic, 92k miles on the clock, 100% bone stock except for a JB4+flash, DCI, and Fuel-It Stage1. Testing was done on 40% E85.

Firmware used was 28.82 for the JB4, and the flash file is JB4_MHD_I8A0S_E85, which we expect to post later today with the rest of our MHD development files. Note, power will be the same with the BB flash files.

The main purpose was to test out the new back end flash JB4 maps. If you've been following along you know that if equipped with a back end flash map will select 4/2 on the JB4, which alters its map set. Currently the new map 1 targets 15psi, map 2 targets 17psi, and map 7 targets 19psi. These are peak values and taper towards redline. Map 4 targets 8psi across the board for a "stock like" low boost map.

Overall I was happy with each maps performance and did minimal actual tuning on the dyno. This chart gives a nice spread of what to expect with the new maps when running our back end flash, in a tune + intake only environment. Next up we'll procure a FBO car for some addl testing of the same maps.

Also, I did some map 5 development tuning, and will be posting about that later.
just a quick question, is E60 required to run map 7? i see here you are running E40 for map 7 and the logs look good and in the MHD thread you stae the E85 flash should be used with at least E40.

I was wondering the exact same thing, why do we need only e40 for map 7 now? Maybe its different for a FBO car?

It's a case by case basis now but e40 may work best especially FBO.

E40 = 40% ethanol 60% pump gas. DCI = Dual Cone Intake. FBO = Full Bolt Ons.

your stock lpfp likely won't be able to keep on map 7. map 1 and maybe 2 should be ok if your pump is healthy.

Stage1 and the (leaner) E85 back end flash is normally required for map 7 on e40+.

Curious what a FBO (minus meth) car would do with the same flash and jb4 map? Any short-term plan on getting that on a dyno Terry?

I've been running E30 for a while now and still on my stock LPFP haven't had any issues thus far, been running this mix for about 6 months now.

How come you wouldn't suggest Map 7? curious to understand from your prespective.

I'm on FBO on stock turbos and stock H/L pumps

e30 does not provide enough octane rating to support the aggressive tune setup for map 7. e60 blend or higher would be ideal for that map, or else I'd just stick to map 5.

I was thinking more along the lines of the increased boost (19psi on map 7) would put more taxing demands on the fuel system than it being an octane concern. 19psi in the midrange really isn't overly ambitious on E30-40 if the fuel system can keep up. The E85 flash timing is what 13-14 peak which isn't that crazy with > E30 either. I've been running more timing down low (and up to 13.5 peak) for over a year with E30-40. I'm all stock except 5" intercooler and drop in filter. No corrections now at 117k miles (I don't run 19psi of boost either but 18 tapering to 14 at 6000rpm)
