Add in ISCPosition and Battery to your captured/displayed values lists.

Something doesn't seem right with the idle log. Your AFRatioEst is reading very lean, and your OldAFRatioEst is reading somewhat lean (after the properties are set). When was the last time you free air calibrated your LC-1?

Craig, any input on the idle log? It seems like fuel settings should be adjusted, but I'm not sure which ones and in what way.


The cruise log has the same AFR issues.


The WOT pull isn't horribly helpful (especially in seeing how it compares to the other two logs posted) since the LC-1 isn't logged. But that log contains a significant amount of knock at the end that should be addressed.

Craig, any input on the idle log?

At a glance, I'd say there is a rather nasty vac/boost leak somewhere.

He's pulling 15% at 50hz, and CombinedFT is still at -22% or so. The front O2 is switching as it should, but it never reads above something like .65v, which is also something to consider. Aside from airflow being whacked, something just seems "off" with this log... but I can't quite put my finger on it for some reason.

OP - I want to see the results of a BLT, and that you have checked for any exhaust leaks.

Also, try to get a 30 second idle log with the car locked in open loop, if you can do it without it going incredibly lean (16:1 or less is ok for an idle log).

He was referring to us, right Craig?

so modest jk. ive got a question: i ran into a similiar problem, not having afrest and lc1wb not matching up. is that a mafcomp thing? im still learning too and unfortunately i can only read right now cause the engines still at machinist.

 

[snowborder714]

You are correct. You need to tune the MAF Comp sliders to get them to line up.

hey i thank the both of you for helping me get this thing online i will do a BLT when i get home tonight.

could the wacked out airflow be a bad maf sensor?

the last time i calibrated the wideband was when i installed it last week went from the aem uego to the innovate mtxl

 

[Calan]

Any updates?

 

[jason91dsm]

current update stopped trying to tune it for now just made it drivable
1) tested the 2g maf came back bad so just threw on the 1g mac till i can get the map sensor and iat sensor to go sd.
2) o2 sensor went bad have to replace.
3) opened ecu and has white residue sending to ecmtuning to have them test and replace needed parts just to be on the safe side.

but will update as i get her back up thanks again craig, snowboarder

 

[jason91dsm]

here are some more logs went to sd any adjustments would be awesome.
