79xd250 Posted September 23, 2021 Share Posted September 23, 2021 I’ve been tuning my timing table through auf16630 MBT spark on my na fg manual. I’ve data logged it a couple of times now, gone through and looked at where it’s pulling timing and then adjusted the spark table to resemble this. the car does feel better and seems to have a much lore linear torque curve but im wondering if the number in that column always mean it’s regarding timing by said amount or can it sometimes to adding timing by said amount? For example at .5 load and 2000rpm -4 means it’s retarding 4 degrees always or can it also mean it’s adding timing at a rate of 4 degrees ? My logic says it’s retarding and also tells me that where it’s not registering a number in the spark adder column then there is no knocking and it may actually take more timing in these areas. can anyone confirm this?
