I've been running stage 1 debating whether to get Meth injection going again or just try stage 2. There is some 93 octane about 30 min. from me, but I think that would get old week after week.

I'm running 93 and I found with 2-3 gallons e85 it really runs well.

Have y'all considered the MP trans flash? So far it's worked well for me on their ST1. Not sure what xhp will offer and if any advantage

I've been running Stage 2 (never even tried Stage 1).
I've been talking to Jarek and have tried flipping between 91 and 93 flashes, but I'm only running 91 octane gas in my car. I tried running the 93 flash with 101 octane in my car and it was crazy to say the least but I'm not trying to spend $10 a gallon every time.

My best advice is to just flash with the same octane as what you have in your car. Using a higher octane flash on lower octane fuel does work but it makes the driving experience a little clunky and you'll get some shift bog.


On other note:
Sorry for not posting any times. I've been talking to Jarek about the times I've been getting and he has been making adjustments to my Stage 2 (this is why I've been switching between the different octane flashes). I don't really understand how exactly the map is set up for Stage 2 but I haven't been running any noteworthy times. Back when I had my Dinantronics Stage 1, I was able to run a 3.99 to 60. Now with the MG flash, I've been running basically 4.2 to 60. It doesn't make sense because the MG flash produces 40 hp & 60 tq more than my Dinantronics.

I recently flashed my trans with MP's 8hp trans tune. The car defiantly feels more torquey.
One big problem I have been having is trying to launch the car off the line. When I engage launch control in Sport + the car builds pressure like normal but when I let off the brake, the car kinda bogs off the line and doesn't pull as strong as it does when I punch it at speed. Last night, I tried launching it in DSC off mode, when I tried to engage launch control, the car struggled to build pressure and then did a quick one wheel burn out then I got a chassis malfunction. I was shocked and just drove softly after it happened and then the malfunction went away after about a minute. I have no idea what happened and I don't know how my car did a burn out since I have xDrive. If someone could help explain, I would greatly appreciate it.

So I went ahead and flashed to stage 2. Driving to the store I noticed my ankle starting to get tired as I tried to not let it touch the pedal too much - it certainly doesn't take much pressure shoot past neighborhood limits. I'm going to try eco mode when I'm required to drive like a granny. Have not had a chance to give it a workout yet.

I noticed Jarek has an update to MG flasher for the logging function, which I downloaded but have not tried yet.

I've been running 93 octane. I haven't seen many stations here that offer 91.

I've considered MP, but want to have an option. After XHP releases theirs, I still may go with MP.

[Brett530]

So after flashing to stage 2 (91), a couple of times now on heavy acceleration I'm getting some throttle closure type hesitations. It could be torque limiting from the AT.

Never happened in stage 1. Anyone else running stg2 have that happen? I probably need to do some logging to figure it out.

I'm using a 1.5 amp trickle charger, is this sufficient for the initial flash?

[Brett530]

It is kind of minimal, but if it is one of those intelligent chargers and you leave it hooked up in advance until it shows fully charged before you begin, and you follow all of the MG Flasher instructions for turning off all the battery draining systems, you should be fine, especially with a 2018 MY vehicle (new-ish battery).

[awilki0101]

I used similar and it was more than ok on a MY16

Completed my initial flash today.

Flashed to Stage 2, 91 octane and Vmax, dcat, exhaust valves always open, burbles set at 7 aggressiveness, 3 sec, and 0 sec base. (I don't really understand what duration base means).

The entire flashing process was so easy, just connected my cable and there wasn't a single hiccup. I did not hook my car up to a charger during flashing.

The sport displays are reading correct at 460 hp & tq. I got a chassis stabilization code right as I pulled out of the parking lot but it went away after a minute. I allowed the car to warm up for 10 minutes then let it rip.

Coming from a Dinantronics Stage 1 there was a noticeable power difference but what I noticed the most was the smoothness.

I am seriously considering a trans flash. In the manual it says you can use the xHP Flashtool but I checked out the app and it only shows 35i cars. I know I can easily get the MP trans flash but I really don't want to spend $500 right now.

I will be posting timings later tonight from my Dragy.

Lastly, I highly recommend this tune!

what ever came from your dragy results regarding the xhp trans flash. before and after??
thanks
