mFlasher 8HP and B58 Official Thread

Since the original thread got a bit overwhelming for most customers to read through hand find answers, we are starting a new thread dedicated to the information on usage of our tool, stage differences and such.

First and foremost, the link to our app:
https://mflasher.com/files/mFlasher_MDG1.exe

Installation instructions:
Very simple. If you already have older version of mFlasher installed, please remove it first. Then Download the app, and run the downloaded file. Go though the installation prompts and you are ready to go.

Hardware Requirements:
Almost any windows 7 and up hardware will work. You will need a Wi-Fi connection active at all times as well as Ethernet port to plug the eNet cable into. A lot of newer laptops do not have Ethernet ports, so you can get a USB to Ethernet adapter on Amazon.

Prerequisites
When flashing your vehicle, make sure that your vehicle battery is in good shape and charged. If it is questionable, put a charger on your car.
Make sure your laptop has good enough battery to last minimum of 1 hour. The flash only takes 10 min at most, but you just don't want to end up in situation where your laptop turns off during the flash.
Make sure your laptop is not doing an update. Updates sometimes disable drivers/hardware and the last thing you want is for your network card to get disabled in a middle of flash.
**If you have any legacy devices plugged in to your OBD2 port that use CAN bus, make sure to unplug them first, turn the car off and lock the vehicle for at least 10 minutes so that gateway reboots. Otherwise your vehicle will still be stuck in CAN mode and disable the eNET access.




Differences in Engine Tune Versions
Stage 1 This flash is designed for stock hardware and is the safest available version. The boost and torque is strictly limited, timing is kept at a very moderate level with adjustment factor 1.10.
This tune is designed to work on high altitudes and use 91oct as minimum. It will adjust for better conditions, but the adjustments are limited to 10%. You can use 2-3 gallons of E85 but gains of E85 will only be really noticed on moderate to hot days. This software is designed to work with stock Trans Flash.

Stage 2 This flash is made for moderately modified vehicles such as FBO. The catless downpipe is not required, but highly recommended. You can run this tune even on fully stock vehicle, just make sure you have access to decent gas, something better then 91. If 91 is the only option you have, then you should use few gallons of E85 or octane booster. This software has adjustment factor 1.2 and will adjust up to 20% under ideal conditions (93+ octane, low IAT, Sea-Level). It has been tested to up to 5 gallons of E85, though your results will very based on condition of your HPFP. This software is designed to work with stock trans flash, but a trans tune is recommended to get optimized results.

Stage 3 This version takes Stage 2 flash and increases overall torque curve and raises final Hp to even higher levels. For Stage 3 flash, we highly recommend a FBO vehicle, through it has still been tested (with great results) on stock hardware vehicles using good 93 octane fuel. With adjustment factor of 1.25, we gave this version a 25% headroom for adaptation so it will adjust for anything form 93 to 100octane fuel and meth. This flash requires Stage 1 or Stage 2 trans tune.



Differences in Trans Tune Versions
Stage 1
Stage 1 Trans flash is based on stock trans file, with slightly decreased shifting times, "granny" limiters lifted, adjusted rail pressure and lowered torque reductions during shifts. This version can be used with stock or modified engine tune and it will adjust and learn accordingly. This is the safest possible tune for trans.

Stage 2
On top of the modifications present in Stage 1, Stage 2 tune removed torque limitations on the trans input, reduces the shifting torque even further, and is ideal flash to be used with our Stage 2 or 3 engine flash. This version does put extra strain on the trans, so make sure your trans fluid is changed regulatory (30k to 40K miles) and your cooling system is performing correctly.
