A way to cheat and fix your strims/ltrims using Rtac Very quickly.

[hquick]

I've been trying this procedure over the last couple of days and the BEN's hit 1.0 very easily.
I'm not sure I'm doing this right though because when I look at my AFR's from the log they are all up around 16 or so???
Any advice please?

accompanying log....bugger...1.01MB...won't load up.

So are you trying to AUtoVE? If so, i am pretty sure you need to have the LTFT's and STFT's off. Also when doing an AutoVE, you need to have something other than 14.63 in your B3647 table or it will mess stuff up. Try 14.65 or 14.67 for a commanded AFR. I also noticed you dont have anything populated in A0014 or A0008 to offset the AFR depending on IATs and ECTs. Again, i dont know exactly what your doing, so I am just throwing a few things out there.

You have to set the update freq to "1" so it will instantly fix the cell instead of waiting for 10 hits. Then it will not modify the cells like you are seeing Finishline.

OK...I believe the above is my problem. I had the update set at 0 so as to keep updating.
Why is that a bad thing? I would have thought it would find the 'perfect' number and then stop...or just hover a couple of decimal places around that number?
Anyway....I'll try it again in the morning with the update set to 1.
But....I'm still confused.

Whippled....thanks for the thoughts (any and everything helps). Read the start of this thread...Jesse describes how to dial in the Main VE using stft's and RTACS. That's what I'm attempting to do.
A0008 and A0014 are set so as to make no alterations to VE whilst doing this 'fix'. The fewer modifiers influencing it, the better....or so I believe?????

EDIT: Also....do I need to apply a filter so as not to update above 80Kpa....or do I just need to set my PE to 80 Kpa?

Something is a miss there Howard.

When you were tuning off your wideband your trims averaged -8 or so, yet your commanded vs actual via your wideband was spot on.

Need to confirm that wideband.

By the seat of your pants, does it feel better to drive using the trim Ben's over your wideband Ben?

Your starting to really get the hang of it now.

Whoops!! shows how lazy i am..

Tried again this morning...same thing?
Wondering if I have an air leak somewhere?
If I had an air leak in the donut just above the NB and WB O2's on that bank..would it cause the WBO2 guage to read lean and the extra air at the NB would cause it to think lean and add fuel?....nope...just thinking about it..that would cause a rich condition? I think???

How do I change the update to 1?

How do I change the update to 1?

Edit/Properties. Hit the roadrunner tab & you have an update frequency setting in the RTACS area.
Howard, I believe you are changing the correction % not the update frequency as this can not be set to 0.

Gotcha, RR users.
