Hey guys, hoping to figure out whats going on. i switched to e85 over the summer and now that its getting colder im having some problems with a lean section after start up. as you can see in the graph, i cranked and it fireed then died, which i know what a need there, but after it starts i get a weird lean spot. my o2 mv drop off to near nothing. Then it goes stupid lean. too the point of almost dieing. I gave it some gas and it comes back to stoich. im thinking its the afterstart enrichment tables but who knows. hopefully someone can shed some light on this.

 

If it's running lean on cold starts, put more fuel into it. E85 is definitely known for wanting more fuel when it's cold.

 

Just in open loop or in the afterstart tables?
