ok then..gen 2 engine (skinny rods)
6-7psi max,m112 sc, no intercooling...pinks on hard acceleration when on petrol but fine when on propane..(engine feels like ecu retarding ignition when pinking as its more powerful on propane.)
petrol is 99 octane..
stock ecu and injectors,aftermarket rising rate fuel regulator
a/f readings on fuel (wb sensor) 11.5-12 on "hard" boost...12-13 on propane..
really used to diesel tuning,so advice welcomed..is the a/f ratio too weak?what should i be looking for when foot to floor?(on petrol)
cures...??remove twin speed fuel setup and go max voltage on pump..
turn up fueling on regulator..
get cold air into air intake..
anything i have missed???
