Elevation Tuning

So what your saying the baro will automatically compensate and adjust the (C) tablesin my #2 tune? Or will it automatically kick me to the (B) tables in the base tune while still using #2 PW at med elevation?
Im not wanting to make it the same james im just wanting to find out if for example your on a race tune in 8000ft will the ecm compensate the (C) table in that dsp tune or will it kick you back to (B) table on the base tune and use that timing* vane position tables. Sorry if I confused some of yall at I was trying to ask.
Thanks Steve and anyone else that's chimed in :thumb:
X2 I agree with both of yall Jed but I don't want to make the B and A tables the same as my C tables. Just trying to figure out which tables the ecm compensates for while your using a dsp tune while your in med high elevations. But thanks for chiming in any is helpful.
If you check tables B0905, 0906,0907 you will see at what baro parameters it changes to A,B or C timing tables. It will change to timing tables B or A in the main tune using those baro readings respectively but will use table C in the DSP tune that you are running. Each DSP does not give you the option for individual table calibration for that particular tune. Most people are not driving in areas where they have a drastic change in elevation therefore you do not have to be as concerned about those changes.
all DSP does is plug and play those segments into the base file. So say you have a DSP2 switch...in the Custom Operating System Tab in the DSP2 OS you will find the tables (segments) to populate with only a select amount of data. That data (timing A&B), desired boost EGR Offf (A,B, &C) and Vane position EGR Off (A,B &C) will get referenced along with the limiters and multipliers in the base file. That's why it's important to set those limiters and multipliers correctly to work with all of the segments you create to be referenced.
I guess that's where im overthinkin it. So for example in dsp #2 which is my tow tune and towing at 8000ft which table is it gonne use?? (B) in main tune when the baro reads the B0906 psi table correct? What I highlighted in red seems like you said it'd use both. Maybe not though.
It will use table B0906 for changing the timing map to Map B and B0907 to change to timing Map A. If all the tables B0905,B0906 and B0907 had the same Baro number the tune would use only timing table C for timing at any elevations. That is why the sensor is important to read correctly.

I finally go it now. Makes complete sense. Now I have another question. My tow tune PW is bumped up a tad should I copy and paste my timing table for that dsp tune to (B) and (A) tables in the main tine and then add the amount of * 2.8 I believe to it to compensate for elevation and the PW? Cuz the C tables are 0.4 and B start at 3.2*.
Ya they're pretty helpful I must say that's why I like this forum better then DF :thumb:
haha my bad Tim damn i knew that too lolI'm Tim. I don't design clothes, or live with Ben:thumb:
So your Non DSP is your smallest tune then? If it were the Big tune I probably wouldn't worry about that if the tuning was done more linear. By that I mean each tune gets progressively bigger and is using a philosophy where the changes start at 80mm3 and 120 MPA and up. Using a method similar to this you would not really see any advantages to mass changes. If you are doing this to learn something I understand you wanting to experiment with it. Trial and error is going to be the way of fine tune it to your satisfaction. Make small changes and not mass changes at a time till you are happy with the results.

Yes that's how they are set up as of now. Alright ill try that thanks for the tips and help :thumb:
