Paxton S550 Acceptable Knock range on datalog?

Sound like the sending unit.. for 18 19 cars the 350 pumps are a great upgrade.

I do have E85 about 30 minutes away and wouldn't mind going that route. I guess I'd have to start looking for a return style system since I don't think my JMS bap and DW95 injectors with my stock fuel system wouldn't support e85.

The 95's may be good but you will def need more ass (volume) to keep up with E-85 demand needs at that level. Most places won't tune E-85 without doing a return system on the newer S550 setups. Lund and PBD will tell you their preferred setup for fueling if you contact them. Best bet is to go to the source.
