This customer purchased the item at our site.
Installation was easy, just need to cut a hole in the rubber boot so the larger unit can fit but other than that, no other modifications required! I ordered it at the beginning of the week and it was delivered before Friday the same week! It can take a while getting parts to Canada

Advantages: Full control over the ECU.
Plug and play, no extra wiring required.
Optional modules available like O2 sensor or quick shifter and with the O2 sensor you can use the "auto tune" feature

Disadvantages: Cost. Defiantly not the cheapest route so if you don't plan on swapping out parts a lot, you might be better off with just a re-flash.
Connecting it to the app was honestly the hardest part... Once I realized you needed to connect to it like you would a wifi router, it made more sense. So for IOS you go, settings - Wifi- and with your key switched on, kill switch on run, you can connect to the aracer's wifi
