Idle Tuning - Base Timing
OK, we are going to go one more notch and add another 2° for a total of 25° of Base Timing advance
And we see 36 kPa of pressure inside the intake manifold, however the coolant temp started to climb.
So that's how it's done, now on our stock engines these gains will be small so I would consider this fine tuning and it's really optional, but if you are seeing gains of 3 to 5 kPa then by all means tune that down as long as your engine stays cool.
Most importantly tune for how you want your truck to feel, how you want it to run and drive, and don't get too lost in the numbers, you don't want to get the perfect numbers and have it run hot and overheat, know what I mean, find that balance, you can always back off the timing advance even when you find the lowest manifold pressure. Turned out this engine did not like that much timing, it even got hot at 23° degrees so I backed it down to 21°.
