Welcome nice to see someone local to me on here!
I am far from an experience tuner but got my fox turbo dialed in nicely using all of Decipha's files and help along the way. From what you have posted it looks like you are on the right track. If the car has 80 lb siemens deka injectors Decipha has a patch that you can enable to auto fill all of the published parameters, if the injectors are different disregard.
The ad counts for the MAF transfer dont match Deciphas histogram perfectly but may be close enough not to matter. You could edit the histogram to match but it would probably be easier to change the ad counts to 25 increments to match the histo.
Good luck and hopefully others will chime in if needed. Also nice to see a shop willing to tune "old school" if you will. I called another local shop just about getting on his dyno to get some numbers and maybe make some tweaks to see if I could find any gains. He may have misunderstood and thought I wanted his tuning help but when I told him I had a power adder with the stock computer the noises he made over the phone showed his disapproval lol.
Very small world I guess. I live in W.Seneca & my shop is on Seneca St. in Elma. Car has Fuel Injector Clinic 650cc injectors that I plan on running at 40lb pressure delta. Decades ago I had a nice 89 LX 5.0L and would like to find a clean one again but the market is kind of insane for what I want. My car was a hatch but I would love a 92 LX notch
The AD counts for the MAF I just took from Deciphas data for the 90mm Ford MAF transfer he has posted from PMAS. I am sure changing it and just dialing in the curve on the dyno would be no big deal.
Going to be honest this is probably easy however it isn't in my comfort zone because I am usually doing newer boosted Coyotes, Hemis & LS/LT combos. Will be nice to take a mini vacation from drive by wire & torque based controllers. Pretty sure I am the only local shop that has a load bearing (eddy current) chassis dyno which is what you ideally want to tune fuel & spark. Curious where you called locally? Once the weather cools a bit and my work load drops to a more manageable amount I would be willing to rent you some dyno time & lend a hand if needed. I have about every sensor you can imagine on my dyno along with very accurate widebands from ECM.
