2. How do you tune it? Dyno?
Tunable and non-tunable have the same mapping. The only thing with the tunable is that you can modify the mapping with an included software. The basics are :
- the data is displayed on a 2 axis scale. Horizontal axis is voltage (0-5 volts) coming of the throttle demand. Vertical axis is RPM...so you can figure it out...the part of the mapping you want to modify is high demand (4/5+) at high RPM (3800+).
The stock mapping of the car is pretty rich...you have to lean it. CP-e already dyno-tune all the cars with stock setup but if you had some of the thing you might want to play with your AFR. The number you enter each cell means the % of volt in less you want. Because a low value in the ECU means leaner AFR you want to ask him to manage a full throttle at 5000RPM as it would manage it normally for a full throttle but at 4500 RPM makeing it leaner. Just as an exemple if I put 5 in a cell it would means that for that specific Throttle position/RPM I ask the ECU to give me the mapping minus 5%.
Since the CP-e does not replace the ECU at all but instead catch the volt signal before arriving to the ECU go thru the CP-e box to modify the volt signal and then go to the ECU.
