G'day all, I think this is my very first post on this forum, having been a long time lurker and reader.
I own a 2001 HSV Senator 300 M6, which has an LS1 engine - ETP215 heads, Comp 215/223 @111lsa camshaft and all the rest of the good gear.
I recently purchased EFIlive - after doing the spannerwork on my engine mods and have enjoyed an immense amount of assistance from forum regulars here - JezzaB, macca_779 and Swingtan.
I'm running MAFless - OLSD - as the car came stock with this configuration and I'm using EFIlive COS3. I updated to the latest drivers / Firmware, etc yesterday.
JezzaB provided me with a good base tune and the other two have assisted with tweaks to dial it right in for me.
I've reached a point where it is running extremely well - great manners and the driveability is excellent. It is making around 395rwhp at the top and around 411lb/ft torque.
Anyway, I've been playing around with my idle settings lately - going through the tutorials written by Weatherman Shawn and others (thanks lads), but have come to a point where I am a little perplexed.
At idle my commanded AFRs are not corresponding to the WBo2 readings. I know the gearis dialled in correctly, because the AFR readings match when off-idle and throughout the rev-range - well, within a couple of percent anyway.
I've attached a copy of my latest iteration of a tune and the accompanying idle log.
What do you think? Any assistance would be greatly appreciated.
cheers
