F10/F12 Backend Flash + Jb4 Stack (M6)

2013 M6 Coupe
-Backend Ecu Flash + JB4 BCM at 24psi on 93 Octane (Custom map 6)
-Stock Exhaust and intake

I had BMS stage 1 and car ran great at 19psi. I then installed Jb4 with BCM and at maxed out fuel trims and car was running inconsistent and funky. I said Fuck it, doing backend flash as I wanted to retain the JB4 BCM boost control feature with the Friendly Burger Tuning app. So.. Hats what I did!

Had the car now with over 300 miles on The combo above and the car pulls like a freight train!!!! Consistent all the time no issue.

See video below. Keep in mind Only mods are the tune stack on 93 octane. Everything else is stock!

Pulls strong. Details on the flash (brand, stage, max psi, etc.) and the JB4? How is your DCT handling it?

Dyno was mainline Dyno (Lowest reading Dyno, lower the mustang) I did 555whp on 22psi Map 2.

The Jb4 and backend ecu flash works by adjusting to all boost parameters and utilizing the jb4 and BCM as a boost controller.

For comparison on Map 2 Jb4 and BCM without Backend flash I did 620whp on a dynojet.


The video above is at 24psi. After speaking to my tuner I can do 25psi on premium 93 and 27-28psi on race gas (E85- Ms109)

So far no issues with clutch, the thing pulls so damn hard as you can see on video.

Who needs downpipes and that annoying flutter when you can do this and have the power without the annoyance!

Tuner is Info@EnzoPerformance

I will be dynoying it on same Dyno (dynojet) that I did with previous JB4 only and see result. Shooting for 650-670whp.

They have done my last car (world record 550xi) FBO and tune only I did 11.5.

Thanks for the info - sounds like a great setup. 25lbs on pump 93 seems like alot, but looking forward to seeing your results and how the car responds.

Do you have a log of your setup now?

I have logged and sent around to Terry and my tuner and all checks out good.

I will be going for world record tune only 1/4. Mid to high 10s as the car should be on dynojet approaching 700whp which should be possible.

Will be testing E85 on 27psi also.

Heres a little secret to get you there.. run Aces IV with your 93 octane and youll have the fastest 93 tune.. it will give you an effective 99-102octane.. its a fuel additive that oxegenates the fuel allowing it to burn much more effectively.. this has the same Effect as raising the octane by a ton..its also designed as an upper cylinder lubricant.. this will keep your temps down and engine safe at high boost, and it has detergent qualities, and does not foul plugs, leave residue, effect o2 sensors or the cats..

I stopped running Race fuel, octane booster etc.... I just uses Aces IV.. you should be able to run crazy high boost with it added to your 93.

A lot of people say Aces IV is too good to be true, so I tried it myself.. and im sold on it.. amazing stuff.. I also put it in my motorcycle and it gained a ton of power..shit is just crazy.. cant believe so few people know about it.. You also wont be able to find 1 bad review on the entire internet on it..

Enjoy my little secret and good luck w the crazy tune

Sure. sent ya a PM. its the regular Aces IV stuff, I always just call and order.. the guy is very nice and helpful..

this could turn into a really interesting thread fast if your able to make high octane boost without knock on 93 with this additive.. I cant promise it will work but I have a strong feeling it will..
