I'm FBO on 91 oct and hitting 14-15 psi autotune with map 5.
Think I would benefit from getting this flash? Car feels good but there's always room for improvement.

You will get a permanent Engine management light if you flash a US map because of the DMTL sensor we don't have in Europe.
You can copy all the values of the map using your own bin, Tuner pro and and correct .xdf. There is a catch though. You must copy all values BUT the torque monitor ceiling sheet. If you alter the torque monitor ceiling values (and a few other maps, some of which are not mapped in the xdf yet, but the back end flash don't modify them), the engine won't start. That's because the torque monitor ceiling belongs a memory zone that needs to be re-signed if it's altered, unfortunately the free flashing tool can't do that. I'm working on a solution.

This , and euro cars have a higher MAP Max voltage which shouldn't be edited too.

Not sure, but you certainly rescale the voltage<->psi conversion, leading to a slight false boost read.
AUS and EURO car have a higher MAP max voltage than US cars.

So, resuming, i should copy everything except the "no identified" zones, torque monitor and Voltage?

Sorry late to the party over here. Here is Cali we only have 91 as you know Terry. I do have an e85 pump near by. If I i do the 40/60 mix to get my 93 would that be sufficient to run map 2 with a pump flash? or does that defeat the purpose?

What happens if I use map 0 and pump flash?

When I take the car to yearly inspection or dealer, I usually switch to map 0.

I think some of the *** emissions monitors are turned off in the BMS flashes.

Just saw this thread... I've logged and can definitely feel timing pulls on map 2, doesn't show up at all on map 1. Running the pump gas flash, 91, FBO with a 450 walbro. Did 418/439 on 2/3 e85, same flash, map 7 and no timing pulls so I'm pretty sure it's running well.

Here's the log, any input? Seems like she's falling flat on her face around 4300

looks like the JB4 went into failsafe due to misfire

update firmware and interface and post a log in map 1 and map 2 in the support section

would a misfire be logged in the shadow codes or anything? I've never pulled any misfire codes, just a failed thermostat for the last few months.

I don't really have the resources to update the JB4 right now, I kinda figured I could "set it and forget it" once I had the car running right :/

Guess I'll try back when I can figure out how to get the jb4 firmware up to date

Here's the dyno log from 3 weeks earlier if that lends any insight http://***********/u/tc535i/8214-eas-...1&zoom=176-219

if you can take logs, updating the firmware is no different

misfire codes don't always show up, and sometimes will be deleted if the auto clear function is on

from the logs: you are running an incorrect flash for your fuel; trims are too high, AFR too rich, insufficient timing advance.

Hey guys so i am planning to run an e50 mix with 91 on my car and was wondering if i had to get the e85 flash or just get the pump flash and run map 7. Also if i do the e85 flash do i have to have e85 all the time or will the car adjust to when i don't have e85 like map 5 would.

running e50 with the pump flash is not really adequate as the fuel scalar my prove insufficient (fro 30% e85 fine but e50 is 2x more ethanol), and you'll get a timing advance curve suited for pump, not e85 mix - that leaves a lot of power on the table.
Best practice is to flash the proper backend when changing fuel type.

The RACE flash is setup as a hybrid setup that will work with pump and E85 mixtures. But, for straight 91 octane, I'd want to be on the PUMP flash. The PUMP flash can support up to around 30% E85.

So in order to do the Bimmerboost flash, I need a Bavarian technic cable? It can't be done using the jb4 usb cable? Wanna make sure before I spend more money haha

For bimmerboost, the $179 cable.
For MHD, $40 KDcan cable from bimmersoftware.com and $79 Android software which comes with more capabilities than bimmberboost

I have a jb4 that I need to get some use from because it was a little expensive but I've heard of the MHD being a great option. I might have to look a lot more into that. And no androids here man! iPhone only haha.

If you want to go the BB route and not deal with an Android device, PM me and I can sell you my Bav Tech cable (for a lot less than $179).

This is all with the BB flash right? How would the mhd flash differ? And with 93 and meth would the race flash be better?

i would stay FAAAAR away from a bimmerboost back end flash. there were cases of people bricking their ECUs. Nothing like that will happen with MHD. I dont think a single person is running a bimmerboost backend anymore.

just go with an MHD back end, that what i use with my JB4.

There are plenty of people using the BB backend flash... mine is currently on one. The software is fairly easy to use too. MHD hasn't been around all that long.
