If you update the firmware to allow Map switching by the BC button, does it disable the normal BC button functions ?

Terry @ BMS 08-03-2018 09:28 PM

Nope, those work normally.

You can not compare that way due to DA. My best stock was 11.23

Where is your time slip ? Post it.

Bushidopupil 08-04-2018 11:00 AM

Onfire, that's good for the DA. What fuel and was that with JB4, what map? Great times!

PURE STOCK Slip.

93 pump on Map 1. Not trying to set any records, etc. Leaving it set to 1 as it's exceeded my goals for a daily/vacation driver. JB4 is an excellent platform. Very smooth power delivery. Feels stock.

Best I was able to do fully stock on pump gas was around 11.3s. And 11.15 with E30 mixed in. Seems to be a lot of performance variance on stock cars. Probably due to weather, baro, fuel quality, DME software, how good the launch is, etc. I expected it go to 10.8s stock on pump gas too based on magazine reports but didn't happen.

Took map2 to get down to 10.8@133mph for me.

I have car sitting in garage with a couple gallons of race gas waiting for a cool night to retest map3. Been super hot around here lately.

Bushidopupil 08-04-2018 11:28 AM

Onfire, that is awesome! Pretty much exactly what I'm hoping for.
Terry, can't wait to see those race gas map 3 results. I found a place close by me that has 5 gallon jugs of Sunoco 260 GT+ that I could play around with, but 90% of the time map 1 looks like would be enough for a DD.

Well we installed and everything went smoothly. The Bluetooth works great.

However I do get a drive train warning everytime i turn on the car...then I press OK and it goes away now I do not know if its limiting power etc or what the issue is. Seems I am not the only one with this problem? It happened right away after we installed it.

I havent had a change to get any logs however I am going to.

Moe from DME was awesome enough to configure remotely since he is recovering from a surgery and everyone at AUTOcouture Motoring in NJ was extremely nice helpful and professional. Great guys and great shop!

What is that meter or dyno app thing you all use to measure 1/4 mile times and such i see screenshots of?

Also anyone have any input on drivetrain warning? Do you guys think I could be damaging anything?

sam321 08-04-2018 12:11 PM

Also guys how do I use the launch control?

If you get a fault every startup that doesn't really do anything (e.g. not low power mode), you installed the EWG wires wrong. Per the install guide the EWG wire with the added black wire has to go on the passenger side of the vehicle otherwise you get that false alarm fault. If you have a fault that is a low power mode then maybe something else so you'd want to contact technical support with installation photos and a code read out to further diagnose.

Understood. I did just talk with Moe so he will reach out to see how they hooked up and see if they incorpriated your fix and if so then he will reach out to you.

I am ordering the dragy for some data for everyone here and you and also we will putting the car on a brand new mustang dyno starting with just the JB4 then one mod at a time to show gains for the community. Intakes are next. Currently I think Moe has me around 22PSI peak it looks like. Car is extremely aggressive and I keep showing off the Bluetooth because that app is HOT :)

Terry @ BMS 08-04-2018 12:39 PM

Sounds great! While it's strapped down we can play with some map6 settings too if they email me at the time. :)

Bushidopupil 08-04-2018 01:21 PM

Sounds good Sam321, looking forward to your results.

Yes I do, all sent and verified through Terry, all JB4 maps are performing strong and without issues.

Absolutely, it will increase the whp number in dyno sheet, but delta/gains are still the same, very happy with the results:happy

Somehow I missed this....That is an insane increase with just tune and fuel!! I also have the 260 GT+ near me! Can't wait to get my M5 and JB4! Outstanding bro!! Thanks for sharing!!

My pleasure bro, this car feels so much different than the previous generation, it is definitely more fun and loves the JB4, gains with just the JB4 and racefuel are insane considering car is otherwise stock. Can't wait to see those 10's in the 1/4 mile dragstrip with stock tires:burnrubber:

Bushidopupil 08-05-2018 10:47 AM

Yeah, 10's for sure on stock rubber with those power numbers!! This is exactly what I have been waiting for!! I'll daily map 1 and track/play with map 3 on race gas!! My Comp. Package is already built online.
What other mods are you considering?

onfire 08-05-2018 03:01 PM

You guys will run deep into the 10”s at 26psi if you can hook it. That’s big power.

rygre 08-05-2018 07:19 PM

Finally got to the dragstrip yday and thought I would post my stock times. Cant wait to see what the jb4 will do!

Bushidopupil 08-05-2018 07:24 PM

Great times for stock! What was the DA?

onfire 08-05-2018 08:42 PM

Killer times pure stock ! BG is a good track. Around 446ft msl. At 6:30 pm it should “ballpark “ around 2800ft.DA.
