Just received and installed the A Racer mini X ecu to control my fuel and spark, I have:
-Yuminashi 143 bbk
-Pcx 150 injector
-Tb cam
-Foam pod filter straight onto the throttle body
Installation of the ecu took me a good 4-5h with a short taco break, along with gutting the cat and installing the wideband o2 bung into the stock exhaust.
Ecu location is right beneath your butt, which required taking apart most of the body panels along with the fuel tank.
The ecu is literally plug and play and does not need any additional modifications to the maf sensor as I've heard from some people and saw in some posts. Bike started right up and idled perfectly. Pretty impressed with this stand alone unit as compared to the Power commander 5 piggy back on my Husky 701 sm. You basically control anything and everything you want.
I went on a 20-25 mile ride to get my tables corrected via the autotune option. Which it did correct significantly. My commanded Afr was 13 with 12.5 being the richer option for the high tps, high rpm area. The stock map seemed to be 10-15% rich in the low to 5-6k rpm area, and lean around 10% anything above that. Autotune corrected that into my tables very quickly, within literally a couple of miles. Another thing is that the corrections came very quick as compared to the stock ecu correcting very slowly it seems.
Overall I am extremely impressed with this ecu, highly recommend it if you can somehow convince yourself and your wife of the crazy expense. My advice is always: it's easier to ask for forgiveness than to ask for permission lol.
Edit: sorry I forgot!, the rich/lean comment does not really apply, as I've corrected the whole map -15 % across the board from the get go, due to the bigger injector. So I guess if you'd have the same setup without the stand alone unit, you'd be running OK up to 5-6k and then extremely lean anything above that, probably in the 15-16 Afr area without any efie. I don't know how fast or how much would the stock ecu correct for that.
