With the open loop eq tables not there, what do i use to tune the afr while in open loop? Right now I'm running at .7 lambda without PE while in open loop. I don't know if this is normal or not but something tells me it shouldnt be that rich without PE active. Sometimes it happens with light throttle and low rpms as well. Causes truck to kind of stumble. AS soon as truck goes to Closed loop it goes right back to 1 EQ. Is there any way to get the open loop eq tables on my ecm?
Is it normal for open loop to call for .7 eq ratio even when pe isn't active? I changed the table to. 92 in areas of operating temp and it didn't do anything.
I would like the truck to stay at stoich in closed loop and if anything when it goes into open loop get richer as More load is applied. Right now as soon as it goes into open loop even at 20%tps it calls for .85 eq minimum and when I start to lift drops to .7? I want to start tuning maf and ve but I would like to get the commanded eq to be some what around 1 and when I'm under heavy load pe take over.
It's very weird to me. I know the commanded eq ration will change some while in open loop. But I didn't think it would run that rich. I thought PE would have to be on. What's the use of pe in my case if the open loop eq is that rich?
Yes I mean lambda. When I read my aem gauge it shows .7 when under light throttle. I will turn over temp off and see what happens. I'm referring to the commanded eq ratio the truck is calling for. When I go into open loop it drops as low as .7. My gauge shows the same thing. When I let off a little it stays the same when I let almost all the way off it starts to go back to commanded eq ratio of 1 and switches back to close loop.
I set COT to the same as PE, don't know if that's correct/safe or not. Raising the temp thresholds and leaving the enrichment as-is is probably safer, if it's just right on the edge of triggering like that.
One other question for whoever knows. When doing ve tuning speed density my truck has stabilitrack and traction control errors. I read a post about applying a traction control patch which is located under the os tab. But I don't know which one there is TCS patch 1 and TCS patch 2. Which one enables me to tune SD without stabilitrak issues
