Jun Type 3 Fuel & Ignition Map - Stock ITR Block

Post by Johnny_9 » Wed Jul 12, 2006 4:09 am

What is the fueling and ignition adjustment for Jun Type 3 Cams vs. Stock ITR Cams on a stock ITR block?

Before 6000rpm - lower volumetric efficiency? After 6000 rpm - higher than stock volumetric efficiency? So

< 6000 rpm decrease fueling and add timing vs stock
> 6000 rpm add fuel and decrease timing vs stock

Impossible to say without properly dyno tuning.

Theory

I am posting this to discuss from a "theoretical" perspective since we should guestimate how the volumetric efficency should change.

Why do you think, that you have to make a theoretical guestimate of VE?
