My WOT is good in the mid 11's and my idle, crusing and light to medium acceleration all in the 14.0-15.0 area but this becomes a problem when boost begins to build around 2500rpm and im still in closed loop. Doing a brake torque i see that around 41-46% TPS is when i begin to build boost so I set my OL TPS THRESH to engage OL at 40%. I also make sure the FUEL BASE table at above 2500rpm and 35% tps commands a minimum .87 lamba at that point. Upon Datalogging a test drive it seems my changes have not made a difference and even at 3000rpm and 70% TPS i am still in closed loop. I must be missing something simple but cannot figure it out.
On a similar note I would also like to be able to command a leaner 1.05 or so for light cruising and idleing for fuel economy as it get my tune worked out. Is the only way to do this change stoich to a leaner amount (i dont like "tricking" and falsifying data if there is a proper way) or run in open loop all the time? FUEL BASE only affects open loop operation right?
At 4:16 of the log is where i rolled into othe throttle (but not going WOT) in 3rd gear to spool the turbo hoping to see the AFR reading take a dip as i passed 2500rpm but they stayed at 14.3 while boost boost built up to 4psi with no additional fuel inrichment. Am i going about this wrong or why isn't it working?
thanks
