2002 silverado calc ve log help

[johnj]

Well Im in the process of tryin to get my own swap runnin and a friend of mine has been buggin me about putn a tune on his truck. So I broke down with the long weekend and started to do a calc ve. I have never done one before so I followed the sticky and the tutorial the best I could. Well after getting the pids selected I wasn't able to get one of the calc ve pids to come up. We went out and drove it around for a while and put it through about every situation we could think of to fill the maps. My problem is we got quite a bit of data and when I click on the avg cells box on the map page it goes to 0 and the maf map goes to all 1s. If some one wants to take a look at this log and see what im not doing right of if I need drive the truck some more. Thanks in advance 15761

Which pid did not come up, did it have a red X thru it (on the PIDs tab)...?

If so, then on that pid (on the PIDs tab) do rightclick->More-Info and see which other pids it requires... select these other pids and repeat the process.

It never came up as a choice I believe it was calc.ltft. Ok ill try it again and see what the deal was

[joecar]

CALC.LTFTBEN and CALC.LTFT depend on SAE.LONGFT1 and SAE.LONGFT2.


( CALC.LTFT is not needed )

OK I was just following the tutorial. How long do you think I should log it for did the log seem long enough. Should that amount of data get me what I need to do a calc ve

I was told it takes a 40 minute drive to get good data. I have found this to be true ignoring the first 25 minutes to get the final fine tuning done. What you have is plenty to get in the ballpark.

Once I got mine close, I setup a driving tune I could log on road trips and such. Then I figured out what pids my calc pids needed and log them only using my v2. Doing that, my cruise part is usually within 1% of 1.0 lambda.

But for getting it close I would set my laptop up in the passenger seat to monitor the map and try to get at least 25 hits in each cell. I wanted 50, but sometimes id give up on the hard cells to get too.

Do remember, you can never have too much data!!

Thanks guys I appreciate all the help. Would any of yall mind posting up your pid file so that way I can be sure I got all the right things..

Sorry, mine is for an E40 LS2. I don't think it will do you any good.
