Alright, turns out it was set to P04, setting is still a BIT off as it is reading withing .3 or so AFR from the gauge.


Car runs EXTREMELY lean during warmup...playing with warmup enrichment helps a bit, but not a lot.

FWIW it helps to idle on the rich side. I idle 11:1 even when fully warmed up. Doing so helps cold start and all that jaz.

Saml01 has a thread about his warm up problems where I have made several long post to try to explain it to him, but he seems to completely not comprehend any of it and just ask more questions, seemingly as if he didn't read my responses. So perhaps you should read them. Then maybe they'll be of use to someone.

Welcome to AEM Hell.

Here's some info on trying to make the MS match what the AEM is putting out. Everyone (except Dynokiller90) seems to have calibration difficulties with this setup.

How lean?

First, make sure EGO isn't trying to go closed-loop when the engine is too cold. Failing that, if your VE table is kosher then it's Warmup Wizard FTW. As a reference, here's what mine looks like. Note that anything below 40 isn't accurate, as my car has never seen those sort of temperatures:

Blasphemy. Steady warm idle in the mid to high 14s is easily achievable.

My motor purs at 800 RPMs from a 30*F cold start. Most here have problems with cold start. I do not. For me, it helps. And I get a smoother, stronger idle running rich vs. stoich. I'd say "easily achievable" is blasphemy, cause a lot of people struggle to get cold start settings correct.

like 17+ lean...sometimes it wont even read on the gauge. I get on the throttle, it goes to like 12:1.

When running through revs, it gets REALLY lean ~1600 RPMs...kinda where it sits at cold idle.


My warmup enrichments are similar, I need to figure out how to get files off of my archaic laptop so I can post my .MSQ
