Message: [QUOTE="2000wa250, post: 1006379, member: 3399"] two TS chips my friend....makes life SOOO easy. Burn one, take it out the the truck, pull chip off PCM, install freshly burnt chip and hook it up to installed switch and away you go. Even better, if your new files sound, act, or generally are ****, its as simple as turn the truck off wherever you are and swap the chips again. Makes it nice too because I can try 6 different versions of tunes without worrying about them running like **** and possibly damaging my truck before I can get home to burn the known good ones. Spare chip rides in the truck at all times with previous versions of tunes so that in the event that I notice something when I'm driving, I can pull over and go back to previous known good versions without needing a burner, laptop, or any tools. Another thing I would try with your SOI table is to take the stock table in the value format, highlight the entire table, and use the + button to bring it up until the lower left corner value (the one you have highlighted in your screenshot) is at 3 degrees. That would put your max base timing at 13 degrees which is still relatively conservative, yet it would also keep the shape of the stock table. I'd do that before trying to recreate my table. Wont be MUCH different from the file you are currently running which you said you would have no issues burning onto the PCM and running 24/7, but without the drastic differences and peaks and valleys that your current map has. Then you can just play with it using the same method to bring it up or down until you like it. Bring it up little by little until you hit a spot where you dont like how it sounds or how touchy the throttle is or feel uncomfortable with the max value you are calling for, then bring it back down one notch. Best advice I was ever given when it comes to tuning is change one thing at a time, little by little, until you get to a point where you feel uncomfortable with it, then back it down one notch. Applies to all maps. When I first started first thing I did was modify the base SOI file a little bit (to account for the speed of hybrid injectors) then the SOI offset until I was happy with EGT's vs Spool up, then moved on to PW (obviously I cut PW in approximately half on them since I was tuning for 250/200 hybrids). Way I see it, 100% nozzles drop PW to approximately 75% of stock, 200% nozzles to approximately 50% of stock tuning. By no means did it stay there, but right off the bat that is what I did. Then messed with timing to get that to where I liked it, then moved on to fuel delivery (ICP and PW). Its a process. Easy metaphor for me is think of it like carving a statue. You start with a giant block of whatever material you are using and you get a general shape which you refine more and more until you have something highly detailed. I think what scares a lot of people from doing their own tuning is they try to worry about the minute finishing details first, or they try to get every map perfect. Good luck with your revisions. I may be playing with mine a bit tonight as well, but right now I am pretty happy with them other than some minor issues which I honestly believe are hardware related not software related. [/QUOTE]
