It seems like my car is loading up on start-up, seems to be missing a cylinder and then it kicks in ? what do I look at for this? I have eflilive flashscan v1.2 and a RR.
Couple question before I get started
It seems like my car is loading up on start-up, seems to be missing a cylinder and then it kicks in ? what do I look at for this? I have eflilive flashscan v1.2 and a RR.
Well I installed the wideband and grabbed my first log file. Runs pig rich at WOT. Maybe when I come home sometimes I've got my foot into it and it get a little loaded up so when I start the car next the plug is semi fouled and causing a miss until is cleans itself? Still waiting on the efi stuff in the mail so I cant quite get a good set of logs yet but it was nice to see the wideband commander log file and play it back correctly. Need to configure the rpms though....lol
When starting, how rich is it immediately on start up...?
It may be overly rich during startup.
Look for these:
- actual AFR and commanded AFR on startup;
- cylinder misfire counts.
Will do! Thx for the help
So thats E38 and E67 and then all the cylinder misfires pids, if I only have 24 how can I get the actual afr data in there?
You have to either forego some other pids, or ...
log at a slower rate (48 channels)... this is ok since high resolution is not required during idle.
OK I got a log file at startup
can someone look at it and direct me, more pids? need more info how to correct startup issues? Did I get enough info or not?
If read it correclty on the playback it looks like my afr is like 9 at startup and i have a few cylinders misfiring... to much fuel ? how do I correct that?
ok I backed off the initial fuel prime a little after looking a another tune file with mods somwhere near mine.
I dont have a clip for the WBC input into the FS yet but I did log the AFR with my WBC and I can see that it shows around 12.5 at startup but the commanded AFF shows it at like 9 in the log I posted.
I'l flash the new tune and re-log and see what I get.
didnt help, do I adjust the commanded fuel ratio? THis is killing me, my car is like all fouled at startup
Ok did a search and found some info so I changed the startup airflow correction table by 4 across the boards. Will start car and log new results tomorrow

Your misfire counts are low, and may not be a problem.
AFR is too rich and may be a problem.
Change one or more of these tables:
VE
MAF
IFR
Or using a WB adjust the VE in OLSD first.
