It goes like this:

1-2
1-3
4-3
4-2
Interesting. It's not batch; look at firing order 1 3 4 2. It's hitting the current and next cylinder at the same time. It does this full time over 500 rpm?

Oh and y8s...alternator no chargy below 300rpm.
I expected that.

It is some sort of batch, since it always injecting on two cylinders at the same time.

I can clearly see that its not doing the normal sequential injection above 500rpm, which is why I went lower in RPMs on the custom stim and noticed it.


All times are GMT -4. The time now is 04:54 AM.
