As far as advantages to using two tuners there would be none.

Stage 1 or 2 trans tune?

I went stage 1. Didn't want to be too aggressive yet

Was only able to get 3 runs in. Ran out of time and unfortunately we were not able to get the AFR this time. Going to weld in another o2 bung for next time. Being on a mustang dyno I'm happy with the results. Most impressive is the curve. Pulls to end. There is a slight spike in boost early but it acts like it's still learning too. Video on Instagram

Awesome...any baselines for comparison? And is this on 93?

I can't find my original but it was about a year ago fully stock. If I recall it was 290's hp and low 300's tq. We were supposed to do 3 additional runs today without tune but we were running late due to not getting AFR readings to work. 93 octane.

Just completed the initial flash (stock '18 440). Almost thought I had a bad K+DCAN cable because it kept losing connection, but it ended up being the USB to USB-C OTG cable. Once I got a good connection, there were no issues.

It's snowing here right now so can't take it out yet, but we should have some nice days coming up next week.

If hypothetically, the BMW is in for service and the dealer wants to reprogram it, would we want to lock the DME again with MG Flasher before the service visit? And then go through the MG FLasher unlock process again once the dealer was done with their update? I assume it would be bad for (or would fail) their update if the DME is unlocked? --MW

Dealer update will not lock your ECU, it will program only areas which are not responsible for ECU unlock.
MG Flasher is designed to keep the same CVN number along with flashing counter - means software will be virtually invisible to dealer level diagnostic tools. The best way before visit to the dealer is flash back to stock (short flash) accessible from the OTS maps screen to prevent visible modification such "gauges calibration" - do not use "uninstall/return to stock" button - this will lock your ECU.

Understood, Jarek. Makes perfect sense. I see the benefits of the flash counter / CVN work you put in, thank you very much! --MW

Will keep you all updated for the dealer situation. I flashed it back to stock/stage 0 and took it in for misfires after I flashed stage 2. Tune didn’t cause it btw, I’ve been feeling it misfire during idle for the past 3 weeks, it just coincidentally got much worse after the flash. With that being said, the car ran amazing with stage 2 and I’m ready for stage 3. Coming from an active8 it pulled much harder and much much smoother. Best of all: no throttle closures.

Did you log the car or are the no throttle closures just conjecture? Most throttle closures are hard to feel in basic everyday driving.

Did the misfires throw codes? Did it occur full throttle or part throttle?

Thanks.

It did throw codes, it occurred as soon as I started the car and during idle. It drove normal once moving. I should find out tomorrow what’s going on.

I'm about to unlock and flash, but there's one step in the manual that says "press start button twice". When I do that the car comes on and then goes off. Doesn't seem right. I've got seatbelt buckled and door closed.

just press once. All accessories will turn on. Then make sure you turn off headlights and ac.

Thanks...that's what was working for initial reads, just didn't want it turning off mid-unlock since it takes ~40mins.

[henkherrie]

I tested that to be sure. Press button once and just waited 10 minutes. Car stayed on so unlocked the ecu

Will the app continue flashing even with screen off? Or do I need to set something?

Just kept checking every 10 mins and touched screen to keep on as a precaution.

I'm activated and flashed to stage 1. Piece of cake. Power delivery is smooth compared to Dinan stage 1. Definitely more power. Will have more feedback after driving to/from work tomorrow.

On that note, I'm running 93 octane. If I flash stage 2 will I have any issues other than transmission torque intervention? I have zero mods other than Dinan CAI.

No issues. The TCU flash will certainly help and will feel even smoother. A good high flow cat or catless will increase a bit and be slightly louder.

Quite impressed so far. Jarek's responsiveness has been great. Here's a quick screenshot of the sports display with stage 1 flash.

Not sure why the link to the image isn't displaying, but it is below.

• Some of beta users experienced incorrect HP gauge actual reading which shows maximum value around 320HP. All scale calibrations are correct - 480 HP 480ftlb/640NM - please let me know who experienced above problem so I know which software/calibration is affected and will be able to correct our database.

@smoov8124 already confirmed on his F36 440xi - problem is solved!

• Stage 2 was updated to ver 1.3 - overboost issue when in spool mode - especially for cars with catless downpipe

• We are working hard to release “additional options” functions in next MG Flasher update to support following features:
- Burble adjustment: duration, aggressiveness
- Cold start delete
- Dcat
- Exhaust flap always open
- Vmax
