ISX fuel mileage help

[Rawze]

mommaburt or unilevers would be the 2 people on here trust-worthy for decent programming of a CM870. Although there are many places that claim to -- It is very rare indeed to find someone who can program the 870 correctly otherwise, and your problems will only be compounded.

I would try to solve your problems before any of that sort of thing is done to begin with though .. there is no program that can fix hardware issues, especially issues that cause lower then normal fuel mileage etc.
