Hi again

I've recently switched to Siemens deka 80# injectors. Now I'm having an issue with the AFRs going lean starting at 180kpa. Fuel pressure climbs as it should. I've had to add so much PW that the injectors are static before the AFRs are back in the 11.0 range.

I have the 1227165 ECM and have read that those have had issues with the injector drivers. Is there a PW limit I'm reaching?

Are they genuine seimens the market is flooded with chinese fakes now

Yep, I checked them over before installing.

Anybody ever heard of the injector driver in the 165 having issues with certain high Z injectors?

Seems slow in here lol

I run 60lb seimens on them just fine .you don't accidently have the tune setup in single fire mode it will cut flow in half maybe post up your tune or pm it to me if you want me to have a look over it

And a log of the issue

I'll post up the tune a little later.


Just looked at the log and single fire is not active at all, also double checked in the calibration.

In 8D there is a PW limit that needed to be fixed.

Is that the same for this fuel strategy?
