(Thread Starter) |   Not Ranked : 0 score  Need help with spike Sorry if this has already discuss, but as you seen on my log below, I always get a boost spike when I go WOT at 3000rpm. Little spike +21psi then go down 18psi and target boost. I've already reduced WG, load, boost target @ 3000rpm, but still get it  Thanks |

| Not Ranked : 0 score If you are tuning with the AP, then datalog with it. It offers much more than the dashhawk. You are on the right track with lowering the above targets, so you may just need to lower them a bit more. Are you 'ramping' the rates up to be maxed at 3500rpm? Meaning lower the 2.5krpm range more than 3k setting, then up a bit at 3k, then maxed at 3.5k? Are you doing it in both the OL and CL maps? Since the stock settings don't transition to open loop until way up in the RPM range, you need to be meticulous in changing all maps related to that range. |

(Thread Starter) | Not Ranked : 0 score Mods: bolt on with stock K04. I'm using Ecuedit to tune my car. So I can send only send you log with dashhawk. How about turbo dynamics table to avoid spike? |
