JB4 is here!

SuperFlow Dyno using Eddy-Current method, where the Dyno wheel is loaded so you get a more true street number. We strapped it down, measured the tire diameter and put in 4K lbs for the weight of the car. Then put car in "Roller Test" mode, and all pulls were made in 5th gear. Note it was about 105F outside but not sure exactly what it was inside the shop with coolers running and 3 fans in front of the car. Cooled the car down to 120 IAT's for all runs except the Valet Mode MAP8. Fuel was Shell 91Oct
Here is the HP/TQ for the runs:
Stock in C mode = 335/410 - seems low
Stock in Race = 330/436
High Flow Air Filters Race Mode = 335/364 - not sure how I lost TQ
Map1 Race Mode = 419/453
Map 8 Valet in Race Mode=285/391
Map 7 +5psi =436/? (getting the graph again since it did not print)
Map 7 +6si = 438/523
Logs attached and will scan in the Dyno graphs later

anything more on the codes/rough running today?
thanks again for doing the testing. Looks like you skipped doing map 2, correct?

Yeah looking at the Delta I think things lined up, my plan will be to find a shop with a Dyno jet in the fall when things cool off, I’ve only ever used DJ’s so this load dyno as a new game. On the street the thing is insane, I added 3 gal of E85 and topped off with 91 and holy s**t it’s spinning the 305’s even with the 1st and 2nd boost reduction 😎 but it’s totally controllable

Are you using WMI with 3 gal of E85 on Map 7? What Map are you running? I got rear ended last Tuesday right after putting in E30 (4 Gal of E85 with 93 octane top off), so my car is unfortunately at the shop for another month. I had a difficult time finding a shop with a Dynojet in my area. Most use Mustang. I was planing on Dyno-ing. I want to invest in WMI, but I am not sure if I should take the leap yet. Did you observe any codes or issues with the WMI install? Thanks!
The Install of the WMI is time consuming but if you take your time it can be installed very stealth and even keep the OEM cabin air filter box.
I still have not found a shop that will allow me to "rent" their Dyno-Jet most won't allow that unless they are tuning you or doing other work.
Sorry to hear about your accident, that must be very frustrating! Let me know how you do on the E85, 4 gallons is kind of a lot, most go with 3 but my car did not care for it!
#132
Thanks for the prompt feedback. Yeah, 4 gals of E85 is right at E35 topped off with 93 octane. I did not get a chance to fully test the car on the mixture. The additional 2 octane might make a difference on how the car responds. We'll see.

Why doesn't BMS or another tuner (besides Dinan) offer a warranty for an extra $1,500-2,000? I really want to get a JB4 for my girl friends M340 and my C63s when it gets here. But it's so hard to justify losing the warranty. I feel like it would be really profitable for a 3rd party company or tuner to offer this.

have any updates been done to the m177 jb4 firmware to log any of these missing fields?

Any more user feedback on experience with the jb4? Went on 54tech and noticed c63amg people having issues, moisture getting into jb4 casing... i have a jb4 on my pure stage 2 335, with mhd backend flash... i had some good and bad experience with the jb4 on the 335, jb4 case melted onto the board, the connections sometimes suck, even if you install everything properly things might not work properly and you have to sodder connection (power wire)... was hoping to hear more positive feedback from c63s people before I buy a jb4 but can't find much

they told me my jb4 got moisture in the case when my f10 m5 engine grenaded itself
would you trust people who can’t make a watertight air case for $2 to work the complex electronics of spoofing signals to german engine components?

years back I was about to buy a jb4 for my e70 x5m then people were having issues with it so i waited for issues to be worked out before I purchased one BUT they decided to just stop selling it to e70 x5m's... instead of fixing the issues they just decided to stop selling it ... i guess I should spend more and get a dme tune
i am researching jb4 because the logging portion of it is interesting to me as a programmer
i wouldn’t put a jb4 on my car if you paid me $20,000
works for some people but, not worth it to me

mo at dme tuning is world class, he’s the real deal. well respected in the community

It’s compatible with our vehicles and you can use HP tuners free logging software along with the OBD dongle. Much better than JB4 where you’re dumping out a CSV and you have to visualize the data yourself or upload it to get a graph with the PID’s. Much more user friendly and they have great logging software.
It’s a lot cheaper than JB4 for logging and HP Tuners is not only well respected with a great reputation, they’ve been around for ages (since the early 2000’s).

If you want to log, I would recommend purchasing the HPTuners MPVI2 ($300): https://www.hptuners.com/mpvi2/#custom_form_mpvi2

awesome man, thanks. do you know if it works out of the box with w205 or is some kind of special file/mappack needed to make it work?

Dyno Results!
I finally dyno-ed my car last Friday. Ambient temps were in the high 90s. Runs were in 4th gear. Figured it's high time some data for C63s owners is put out there. Bear in mind that the runs were done on the (heartbreak) Mustang Dyno.
Map5 - 7psi peak request over stock, less taper to redline - E30
Map0- Stock operation, JB4 disabled - 93 octane
Map 3 6psi peak over stock, less taper to redline - 93 octane
Mods: JB4, Pedal Tuner, secondary CAT delete.
First run - Map0, 93 octane
Second run - Map3 93 octane
Third run - Map5 E30 (left and went to put Ethanol in tank and came back to the same shop within 20 minutes of first two runs)
Map5 - 7psi peak request over stock, less taper to redline - E30
Map0- Stock operation, JB4 disabled - 93 octane
Map 3 6psi peak over stock, less taper to redline - 93 octane
Mods: JB4, Pedal Tuner, secondary CAT delete.
First run - Map0, 93 octane
Second run - Map3 93 octane
Third run - Map5 E30 (left and went to put Ethanol in tank and came back to the same shop within 20 minutes of first two runs)
