She's a fatty (a pretty one) but she's fast . There's more in there yet. The map 6 setup I used on the M5 hasn't translated 1:1 to this car so I'm back to square one. Map 2 on this car, however and unlike the M5, works nicely.

Nothing else; just an M8C GC with a JB4 on map 6. 92 octane pump has with 6oz of BOOSTane Pro per 20 gallon tank.

On this setup, my 2020 M5C hit 60mph in 2.57s and ran the 1/4 on the same farm road in 10.33s.

There's room for improvement on the M8, though--traction mostly because of the $h!te stock tires that I plan to replace when the world returns to something more normal.

Update to the V5 firmware to start. If code continues then be sure to read it via JB4 app so we can sort that too.

Been making some really nice advancements on additive maps lately. We have several customers running faster with the v6 firmware using an additive map6 than they were on map7 previously. If anyone on good fuel feels like having some fun we could always use more data.

This happened before I tossed the JB4 on as well as after. I did see nickohlie was having trouble with this code so it may be the cause of their code as well.
Grab the v7 beta firmware and see if it helps with that false alarm fault code. We've been trying to chase that down! Note duty bias and pid gain setting changes required also when updating.

Yes we really improved the EWG control on additive based maps like map1 and map2. In fact we've had a few race gas customers report quicker times running an additive based map6 peaking at 7-8psi compared to the previous map7 (which, is now map5 as map7 is WMI on the new firmware).

Only catch has been a few false alarm "boost too high" fault codes we need to chase down.

whatís up guys I need you HELP (brace yourself this a long one)

My 2018 M5 base with comp exhaust used to perform really really well with jb4, my experience with it has been so good that I became jb4 advocate, defending it every time anyone had anything bad to say about it lol
Fast forward to today Iím at 20k miles and past few months car hasnít been performing so well, let me elaborate..

With all test fuel has been 100 oct from a pump and sometimes with few gallons of e85
My car used to do 1/4 mile 10.5-10.8 no problem at 130+ mph and 60-130 has always been 7.0-7.2 with best of 6.8 ( map3) 100+e85
In May of this year few nights I did some tests and my 60-130 was slower by a lot results of 7.6-7.7 were best, ran map 3 again 100oct+e85 temp and da was very similar based of dragy stats. Didnít do 1/4th in May to compare.

Read on a forum another guy had exact same issue and he had changed spark plugs which brought the car back to original performance, so I changed spark plugs as well to OEM once at the dealer.

While car was at the dealer new update for jb4 came out and I couldnít wait to try it with my new sparks.
Well I got the car back few days ago and figured why not measure the 60-130 before doing the update to compare.. and so I did, first thing after pickin up the car I filled up full tank vp101 (there was about 3 gallons of 91 already in the tank)
Best results now came in with map2

7.76 and rest of my test hits in map 1 to map3 were 8 second passes

And so I pull over install the update to run same times with the update of high 7s however I felt a huge difference in the way the car was delivering the power with new update. I also tried 1/4 text and got 11.0 at 129 (60ft was 1.7)

First impression was something Isnít right power isnít linear and boost comes out of nowhere second or maybe even 2 seconds after you stomp on the throttle

Figure before making this post I do more testing with new software update and well it wouldnít let me, after a day of driving on new software any time I pressed the gas over 50% it would throw me in limp mode on map 1 or map2 havenít tried map 3 so I just installed old soft back to log the car again on old software vs new software on the same day.

anyone having similar ďlossĒ of Performance after some time? Note Iíve had my jb4 installed for over a year now. Is it possible dealer had to gap OEM plugs and they did t? Open to your suggestions

Ps Iíll upload the logs tonight

On the 120719 fault it's a known issue we need to track down. In your log when did it appear? Middle of the run? When letting off?

Got it... When you have time see if you can log a similar sort of thing so we can check the data during that condition. You can just start a log manually so it's capturing everything not only WOT.

Hi All, picked up a 2018 M5 base a month ago with 10K miles. Mods are AWE SwitchPath ***-back and charcoal deletes.

Terry, or anyone who can help, mind taking a look at my logs and letting me know how it looks? I'm not sure what gears or speed I need to be in to appropriately log, but these were from about 3rd-7th gear, 60-110+mph. WA 92 octane and about 80 degrees don't know how to check DA. I did 2 pulls on Map 1.

Also can you check if I have the latest firmware? I saw a stable, which I uploaded and a beta, wasn't quite sure which I should load.

Thanks in advance. I previously had a full stage 2 F10 M5 and was running bootmod3. Wanting to try the jb4 platform as to try and avoid any warranty issues if that ever came up opposed to a flash tune.

Mind answering some of my other questions. Am I on the right firmware and are logging situations ideal?

This is on map 1 w/92 octane.

Okay I think I can figure all of that out. How did the logs look on the current pull? Anything bad, knock, no gains? Sorry for all the questions. First time using JB4 and tuning on the M platform.

Hi Terry, I loaded the latest V7 BETA firmware, but where do I adjust the duty bias, pid gain, etc?

I see another the user adjustment settings, but when I click it, it refers to MAP 6, then below I see where I can make changes to PID gain, FF, but no duty bias option. Please advise.

Thanks!

I also just ran codes and I’m getting 121001 TMAP sensor, short circuit to B+. What is this and anything I should be concerned about?

Morning All,

I loaded the v7 Beta and cleared the 121001 TMAP sensor, short circuit to B+ codes and after a couple of spirited pulls, checking TMAP sensors and unplugging/plugging OBD code hasn't come back.

Attached is a map 0 log and a map 1 log. EWG attached, 92 octane. Also my first attempt doing a 1/4, 60-130mph. I didn't launch just flat footed it. I was on sports plus, sport, sport, S3, 4wd sport.

My shifting sucked and I didn't launch but adding those factors still seems like the best time I could have got was around 11.3 ish. I was hoping for more being I was on Map 1.

Any feed back or insight would be appreciated. I want to hold on to this JB4!
