This changes the shift points, torque settings and clamping pressure. It locks certain values in place and resets others to be learned once they are set. The end result is that from a stop, the clamping pressure is higher, allowing for the car to hold the gear faster and longer. From cruising speed, it actually lowers the clamping pressure so when you go to accelerate, it will move to a lower gear faster, then clamp higher so you get more torque, faster.

As a company we don't discount our own products. We run the same price year round. It keeps our dealer network happy and the used price more stable.
Note on the wireless kit the app is sold separately. You can check the price in the app store, its sold by the developer and is called JB4 Mobile.
You can use it to map switch as well so can select stock.

Hi George,
So the JB 4 mobile kit is installed and connected,
I have 2 questions regarding the JB4 mobile connect,
1) when you change the map setting on the go, how long does it take to change all the parameters ? ( ie changing from map 1 to map 0 )
2) can you elaborate what AFR (air fuel ratio) numbers are ? & IGN does ? Thank you in advance !

The AFR is the air fuel ration. On full load it should sit at low 13's relative to which gear the car is in, the amount of load and the exhaust gas temperature.
Ign1 is timing advance. You want this to go up as the rpm increase at the higher rpm point.
Ign2-5 is timing adaption and typically you want to keep this to a minimum or none at all. The ECU will at times as the car reaches peak boost adjust this to help with boost control (torque targeting).
