13B-REW Injection Timing

Postby Slash200 » Sun Oct 28, 2018 10:49 pm

Hello,

I need some help wie the injection timing on a 13B-REW
At the moment I'm running the settings from the basemap.

These values looks very strange for me. Can someone explain the values to me? Why are they higher than 360 degree?
Can anyone post their inj timing for a 13b-rew with stock ports?

regards
Bastian

Because it is a rotary with the injectors on the other side of the engine from combustion, and the fuel cannot physically make it from the injector to combustion in less than one crank rotation under some conditions. Namely light load and idle or conditions of low injector duty cycle.

It is how Mazda also times it in all of their technology literature too.

Okay thank you.
I was just a bit confused because the values are totally different from your video "technically speaking" on youtube:

Differing opinions is all it is, together with technical limitations at the time.
