erm..

ERST - what stops you from 'livemapping' the ignition on these for example?

also OFAC and OFAB would these be different to map with the different map sensors, and to if the map sensor is limited to 1 bar positive - how would you get around this for running say 18-20psi?

and also t2 to t3 conversions on the frst - would the fueling be totally out for the same boost pressure on these, given that the gains would primarily be down to exhaust housing and pressure efficiencies on the inlet? would there be lots of factors in the map and tables to alter for this simple and common mechanical change?

ok so these arent exactly relating to general mapping, but when put into application it raises a few more queries from me.
