BigChiefM5comp · **new to the platform and the tuning. -** 09-14-2020, 05:20 PM

finally got my jb4 connected to my phone and am running map2. I updated to v9 firmware I see is there newer versions then these as well? now what is needed to adjust in the app to make sure all my settings are right for my setup. just have a ********* and the jb4 currently and primarily run 93 only. did a code check and one popped up for intake manifold with plausibility of pressure too high? just need insight on what I am doing as I am not sure. new platform

Load up v10 firmware and evaluate map2. If you have any issues/codes just email me a log and I'll help you sort it out. terry@burgertuning.com

Hey Terry, I'm going to try out V.11 later. I'm on V.10 map2 4gals of E85 16gals of 91 and running strong! I changed the DB to 50 from top to bottom and was just wondering what affect that has? Quicker to boost in the lower RPMs?

Terry @ BMS · 09-24-2020, 02:13 PM

It's just the default for how WGDC is applied, 50 is the same as 0. But some people have random numbers or lower numbers which would reduce boost targeting.

You don't run lean on that much ethanol? Are ppl running 4-5 gallons of e85 now I thought it couldn't add enough fuel to keep up.

Everyone that has been running it has been happy and people are running up to 6 gallons but it's not recommended. At 4gal with another 16gal of 91oct its like running E20, 6 gallons would be E30 and then you're starting to push the fueling limits from what i understand.

Did terry say he doesn't like dp for the car? How come?

Terry @ BMS · 09-26-2020, 01:15 PM

20% E85 has been working pretty well for most customers. Some are able to get up to E30 before the JB4 triggers a lean safety.

Terry @ BMS · 09-28-2020, 02:33 PM

Had a couple reports of the BC menu for changing maps between 0, 1, and 2 not working in the most recent firmware. Anyone here have a similar issue with it?

JK-M5 · 10-10-2020, 04:30 AM

yes. I still cannot switch maps on the fly

Terry @ BMS · 10-15-2020, 02:07 PM

I guess a better way to ask it, anyone not having an issue with the BC map switching?

luchocamp · 10-15-2020, 05:10 PM

Hi guys for Purge meth Map7 is not working. Map 8 is correct. Is good tidea to fix first page ...
Keep it up

Terry @ BMS · 10-15-2020, 05:12 PM

I'll check and fix the documentation!

Hi Terry,

I apologize if I'm posting this in the wrong place I saw your note about using the support sub forum but honestly there was no link in that sticky to the new support sub-forum. also I read through and noticed that you asked people to email them their logs but all I see is Terry at BMS I don't actually see a full email address or when I visit your profile page likewise I don't see a way of contacting, so please excuse me if this is the wrong thread etc. I decided to just go with the most recent
��
F93, BMS Intake, JB4, v9 updated. 94 Oct.

Everything runs great until I connected the EWG bc I wanted to run more than just map 1.

Feels like when the boost is about to kick in, is sputters and

holds it back. Low Boost only or none.

finally I noticed you mentioned an update to V10 or an update to the 11 however I don't see those posted either.

Sincerely,
NoJail

Here's my report after coming back from Shift Sector.

2019 m5 competition bone stock only running jb4 with MS109 on map 5.

Overall the car performed well but I was having intermittent issues with the drivetrain malfunction when letting the car shift itself. Later I was manually shifting and it still did it.

I started messing with the car settings and changed from 4wd sport to just 4wd, that combined with manual shifting I didn’t have any more issues and the car consistently hit 159.5 on multiple runs. The speed limiter cut in right before I hit the flags so I’m sure this would be low 160s.

Terry @ BMS · 11-16-2020, 10:56 AM

Strange on the fault letting it shift itself but trap speed is moving!

Able to read the code that was coming up?

BigChiefM5comp · **questions on mods and fueling -** 01-23-2021, 04:49 PM

so im looking to add primary ********* I currently have secondary. and running the jb4 been on map 2 had no issues cars been running great. my main question is how much bolt ons can be done without having to a true ecu flash? Do intakes really do anything and will the jb4 adjust for the intakes? looking to try and get as much out of the car as I can. if it comes down to voiding warranty then so be it. looking for advice please or recommendations on what's best.

Terry @ BMS · 01-24-2021, 10:41 AM

The BMS intake will add some top end power. Not huge gains, but worth the low cost and easy install. Plus they sound and look great!

BigChiefM5comp · **mods and fueling. -** 02-02-2021, 08:48 PM

yes I've been debating the BMS intakes or the project gamma intakes. questions on fueling with the different maps. can I get some insight on the other maps or with fueling like with ms109 or E85 mixtures. what mods are needed and what not.

Terry @ BMS · 02-03-2021, 11:31 AM

You can run maps 1-3 on E20. If using MS109 you can run any map you want, that's the best fuel for racing. But anything unleaded race gas will do for maps 4+.

adolzero · 02-10-2021, 10:04 AM

a side question to terry on s63 engine for f90，base on your experience what does bmw do on competition models？the 25hp is acheived with a higher boost in ecu tuning？i assume hardware of m5/m5c are exactly same- am i right？

the ultimate question will be，what will be the tuning potential between m5 and m5c？ it makes more sense that running jb4 on both car shall get exact same result in aggressive mapping？or not？

BigChiefM5comp · 03-03-2021, 08:58 PM

are there any new updates to the firmware? I had seen it looked there were some adjustments made. I believe I am running version 10 on map2 with only secondaries as my current mods.

I just noticed the new update 11/T3, I'm going to upload it later today
