Default Targeting exact cells for SD tuning??

When you guys log for speed density tuning are you trying to get an exact targeted reading for the cells in the Main VE table? i.e. To get a calculation for the cell (1200rpm, MAP 50) you have to have a log that is Exactly at 1200rpm and a MAP reading of 50???

This is difficult to do for us guys who use slow resolution rate logging programs if that is the case

Thanks

Before HPTuners, I used the following:

(X-400) through (x-1) corresponds to column X RPM
0-399RPM=0 RPM column
400-799RPM=800RPM column
etc.

For MAP, I also used the column header as the upper bound in the same manner. So 50 is 46-50, etc.

If you are talking about Autotap V1 or similar, Have you tried just logging the minimal amount of PIDS to get the data you need?

Ya, I have the old school AutoTap V1.11
You guys can get fast enough resolution rates to pinpoint cells with HPTuners?

Thanks for the advice JimMueller

Hey Monodax, can you highlight what PIDS is

Got ya. I'll limit it to a few things and see if that brings the samples up. Thanks
