Where to set timing

Swies
If you are spending large amounts of time on the street, at part throttle(PT), and your combo is street-friendly,Then IMO you are missing a wonderful part of the driving experience,by not having the V-can tuned.And even more so if you have a manual trans.
At 15/34 you're right close to my combo.My power timing ,is delayed somewhat, to between 3000 and 3400(dont recall exactly), so that the V-can can flush out the mid range under PT.This allows me to run 3.55s, and accelerate briskly with minimal throttle opening, making it, capitalS, Street-friendly.The can brings in 20 to 22 more degrees at any rpm and depending on the load setting. So right off idle, the timing could be 15+20=27degrees. Later around 2800rpm, it could be as much as 28+22=50 degrees. Between 800rpm and 2800rpm, it can be anywhere between 15 and up to 50, depending on how hard Im stabbing the pedal.
It gets complicated for sure.
The key is to map the two timing schedules out separately on separate graph-papers. And then to combine them on a third sheet. Then to compare that third paper to real world driving, and finally adjusting the maps to prevent detonation, and to maximize the driveability. It really helps to have an on-board way to adjust the timing from the drivers seat.
I hesitate to say that I think that you didnt give it a fair chance, but I know the time and effort I went through to make it work.Its not for everybody,but,I believed in it, and I hoped that I would have the time,skill, and patience to figure it out. In the end, the time was well-spent, as I have been able to pass that experience along ,here in my local neighborhood.
