There was a guy who did this about 100 years ago? Don't know if he's still around?

I really doubt the toyota MAF could be used, have you looked at that thing? Want to make the Toy run better, do the TPS adjustments and then peel of the cover of the MAF, loosen the screw holding down the spring and twist it till AFR comes in line! Works great!
