Hey everyone, thanks for reading this. I installed my Apexi BC, and ive done most of the programming steps, but am stuck on what to do for boost/duty and everything else after that. If someone who knows exactly what there doing help please id appreciate it. thanks EEE

ok boost limit and duty cycle are inter-related. Read the manual. it is on apexi-usa.com if you don't have it.



So how to set it up. Set your desired boost level first. Say 0.70 kg/cm^2 and leave the duty cycle blank. Run the car hard and the AVCR will self tune the duty cycle to try to get 0.70 kg/cm^2.



Once you've done a couple of runs you need to fine tune the duty cycle sometimes to get exactly 0.70 kg/cm^2. Sometimes it overshoots a bit, sometimes it doesn't even get close to 0.70



so if it's below 0.70 add like 2% duty cycle and re-run the car. See if it hits 0.70. if it overshoots subtract 2%



You can also change the duty cycle and program a duty cycle curve based on RPM but I'll leave that for a more advnaced lesson.



Good luck.

i did the self learning step by step as the manual and you said to do it, i hit next when the duty went to astericks, and it never self learned??? the lines in the bar graph are suppose to change and it didnt.? should i just start over and reprogram the whole thing? whats up oh jedi master teacher?

When i set mine up, i Just turned the duty up or down until it held at the boost i wanted. **** the self learning.
