[Diy_efi] OT: Tunning TDi engines, advice sought

[Ron Schroeder]

Check here:

for info on getting the most from a diesel.  BTW, I think about 14:1 or 15:1
CR is the optimum for a diesel except it is hard to start in the cold.
Propane injection is the key to really lighting up a diesel gor both power
AND economy.

(on topic info)  I used a home-brew EFI to inject propane in my Audi 4000
diesel.
