You must be using LS1 Edit or something because HPTuners doesn't break done into Fuel Cell associations like that. Now I'm sure we could do it with some calculation but it sure seems easier to modify based on the MAF HZ rather than the broad range of a fuel cell. But there again I've never done it like that so couldn't say with any authority.

Oh and as soon as someone gets a chance tor try using my Fuel Trim calculation sheet and Sounds Percent Adjustment from Fuel Trim sheets together please let me know what your results are sense I cannot try it on my own because I got the new 1 BAR SD only upgrade and the MAF is no longer used at all.

What I did was to turn the maf back on once done with the ve table and reset trims log maf hz. Then I went through and compared the log noted maf hz-vs-trim level. I noticed trends during say 3000 to 4500 were off by say -8 so i went through and corrected the maf values in that range by a percentage according to the excell sheet values. I did the whole maf table that way and my trim levels are within +-2 now after calibrating the maf that way. The fuel cell tells us how "off" the maf value is.

I believe there is a free program called Star Office(I think it will do it) that you could get for free that will allow you to open the file if you dont have excel

I'm sure there are a few other free programs that will do it too...

Look at the qoute above your post, free program to open spreed sheets in. Actually there are many for free out and thus no real need for Excel. Man I last replied in this thread back in '05, lol.

They now want 35.00 for that program. Does anyone know of a free program anywhere that we can use to open it?

Well, thanks... The reason I deleted the post was that although you can use that "Excel viewer" to view Excel documents you can't edit anything in them AFAIK, so probably not too helpful here.

Sorry !
