So I plan to turbo my sn 95 this winter. I have some tuning questions, and some ideas:
This is all what I have come up with as a work around to not running a stand alone, in part $, in other part know I will never spend the time to reinvent a rounder wheel then the computer geeks at Ford did in 94.
First is run a msd box and a boost retard. Seams straight forward would love input on what you got and what you love/hate. (I would prefer analog)
Next is using 60ish# injectors, a newer maf/iat in +2.5" plumbing and engineering an adjustable air limiter. Something very analog yet to the point, like the idle air adjustment screw...
Next is installing a wide band. Question: all the wide bands I can find read in a:f. I don't understand how that works? Working off of a:f implies an assumed unknown. Especially when trying to run e50-85. Anyone know of a gauge that reads out in lambida?
In my little hamster wheel I call a brain the idea is: The computer will play with fuel trims and get things close enough for me, and I play with the maf adjustment to find a good a:f for when it's in closed loop.
Would think once I get the hang of it, running various fuels would be as simple as turn maf. screw 3 turns to the left, and add 1/2 a degree/1psi or whatever it proves to be..
Also new to tuning with out a knock sensor. Do you just keep it what you think is safe and below, or crank it up until it sounds like an overheat lawnmower, and then back it out a splash?
Thanks for any input!
