I have noticed that warmed up good, mostly at low load and rpm, that block learn gets as low as 80. Idle is around 90, and map reads very close to 1 volt. The map voltage looks pretty normal to me, why would block learn be this low. The injectors look good, but do have high miles on them.
if I do get this thing tuned, I would like to have this kinda stuff straightened out first.
If I ever get the chance for you to tune on this mark, would you prefer it was 7747? any particular prom to start with?
