Wideband tuning question

[TheBuMan78]

Ok a few questions for tuning an ls2 with my lc1 wideband.

1. while tuning either MAF or SD is there a way to get the histogram to report only afr readings while on the throttle. In other words I would like to get the afr results in my histogram to show me acceleration only not decel.

2. If this is not possible is there a specific way to tune the cells that see decel the most (the cells that get skewed results do to the afr going full lean on decel)

I know how to set the car up to tune for maf and for sd, I have read alot of info both here and on the internet I have disabled both DFCO and CFCO and still when I decel I get lean ratings in those specific cells according to my wideband. I realize that this is normal on any car, but it makes tuning impossible. I also have the decel popping that I have read about alot.

I dont have a clutch switch on the car as it is a swap. could this be causing me some grief?

Please someone help me out here

Thats funny...I was just trying the same thing and asked the same question.

Try putting something like Throttle Position "[SENS.90] >0" in a histogram filter.

[Snyper]

I think 0 would be 16 because at idle the TPS sensor is 16% open. Correct me if im wrong(im trying to do the same thing)

[Snyper]

[SENS.90] > 24 I used that and it worked perfect. TPS stays at 18 or so around idle so at first I did 20 and it would still record until my foot came off the pedal. Driving around town the lowest the TPS went to was 25 so I set it to 24 and while shifting I let off the throttle immediately so that I dont record the off throttle afr.

i like to use map sens in the same way

Ya, I forgot the electronic throttle ones don't go to 0%, OOPs.

Thats where steady state tuning on the dyno really comes in handy

[Snyper]

Well some of us aren't fortunate enough to have a dyno laying around nor wanna pay the money to get a dyno tune. To me a REAL situation tuning is the best...nothing is more accurate than the street itself...just takes longer and is a bigger pain in the ass.
