Well i installed the WOT Box the other day, overall its pretty easy to do if you are ok with soldering and cutting ignition cables. I used this as a
guide, the only thing different IIRC were the coilpack cable colors but the N2MB
guide has a chart for different cars.

The job took me about 3hrs in total, 1.5hr of this was the usual dicking around trying to feed cables through the firewall into the drivers footwell area.
The WOT box itself is super simple to program, i am really really impressed with the WOT shifting, its super quick and super easy but i'm just glad i have an uprated clutch, this feature is a welcome addition to the car
The 2-step launch for me at least in a front well drive car with road tyres is hit and miss, most of the time you just lite up the fronts and go nowwhere, i am still tweaking but currectly have it set to 3500rpm.
As Jonny95_SXE said above, he thinks the WOT Box melted his CAT, i can confirm the chances are a WOT BOX will kill your cat, i am(was) running a BF 200cell cat, after testing the 2-step it blew half of it out the exhaust pipe, i only tested it for about 5sec, so beware, if you dont like buying news cats, get a decat before running this mod.
Here's what the cells from my cat looks like, luckily i am not worried about killing it, it barely past the emissions test the last time round so i knew it was on the way out, maybe this part was already melted and a restriction hense the system blew it out, we will never know, i do know i always wanted to run de-cat, not such an expensive one though, LOL.
This weekend family, work and weather permitting i will take it off and remove the remaining cells from it rather than buying a new test pipe.
P.S the rest of the cells are on a road somewhere in ireland.
