I tried it and everything worked well. Power was down in upper rpm band as boost tappers down with DME and offset settings. I ended up going back to my original setup.

What I noticed was that the IAT seems like the likely issue. My temps are going to 120+ and DME is reacting negatively to that. I may need to mess with IAT Spoof to adjust down since WMI is actually lowering it past the sensor.

BMS... Any suggestions on this?

I'm trying to figure out which firmware and map I should be running on a fully stock 2016 330e (with essentially the B48 engine from the 320i) running on 93 octane (98 RON in Europe).

Am I correct in saying I need to use firmware V11 and Map 1 or max 2?

BMS can comment but I thought the IAT spoof only raises IAT to try to get some higher boost targets.

It should be lowering IATs to increase timing. Boost on map 7 is additive of map 3, but acts like absolute from what I see. Thus, boost stays constant in my logs, but timing decreases as IATs increase to reduce potential knock. DME Boost reduction only kicks in if there's a trim, AFR, overboost, knock, etc. Only sign of intervention I see is timing. When it drops out, power drops significantly.

Maybe. Need BMS to comment how it works. Or you could just try the BEF, which will happily let you make as much boost as you want (assuming EWG harness) while adding fuel to help with timing. Agree that high iats are an issue but I think itís because the DME adds boost to compensate for less dense air, which might have the negative effect on timing you observe.

Terry have you got a hold of the new M340 yet? I’m wondering what the JB4 can do for this car since it already has over 380hp. And also i believe it’s the same engine has the previous model?? I ask because it might be my next car when i return the Q50

Its the same great engine, but some of the components are different.

Not yet in house but I'm sure we'll be able to improve it!

What is the latest firmware for the B58 ? I see some post talking about BMW_B48_B58_12_V3. I can only find 11 on the first page of this forum

Thanks

Yeah thatís what Iím waiting to see. Would the back end flash be compatible for it as well? Really looking to get this car as my next lease if i could get a good deal for it.

v13 is the latest, it's in the BEF thread currently: B58 MHD Back End Flash Maps - N54Tech.com - International Turbo Racing Discussion

Use this one, follow the link : https://www.n54tech.com/forums/attac...8&d=1557076291

This is the latest version. I have used this without the BEF and now running with the BEF, i am also in the UK, it runs well with our higher Octane Petrol/Gas, DO NOT PUT THE CHEAP CRAP PETROL/GAS IN YOUR CAR...

Hello.
What is AFR on B48 on map3 (20 psi)? I have 12.5-11.8, is this normal?

Are EWG wires needed for any of the additive boost maps?

EWG wires arenít technically needed for any maps but are useful if you really want to dial in the boost esp on map 6 or 7

EWG connection is suggested for maps 6+ or if using a back end flash map. For maps 1-5 not really needed unless there is a unique situation where you need extra wastegate control.

Terry... Can you provide some details about IAT Spoofing for WMI users? Specifically, is it only active when WMI is active? Does it lower IAT evenly across the pull or is it progressive? (Map 5 looks progressive) What's your recommendation for WMI users? Does it show in IAT immediately and is there a way to see actual? Is the setting in degrees? ( Ie: 20 drops it 20 degrees) Is usage just setting FUD 2 and entering value in 6cyl timing? Is 6cyl timing still active if we use spoof.

There's more questions around it and it may be best to add to the first posts. I've searched and didn't find these specifics, but I did see many asking about how to use it, why/when to use it and what it really does. Thanks for your time.

Normally you'd leave it off (6cyl = 0). It's just a tool we use sometimes when logs indicate it might be helpful in one way or another. Given the recent developments with our back end flash it's less useful because we can make the changes more directly in the flash map itself now.

Looks like I need to bite the bullet and get the flash. Lol. Is it still in beta or mostly dialed in? Obviously, as we learn more we update it, just wondering where it currently stands. Thanks.

Sorry terry 1 more question though, I just realized you said if fud6 is turned off v13 acts as v11 with the same map guide, except I just noticed v11 map guide has valet mode on map 4, but valet mode on v13 is map 8?
