Both second hand been offered to me guys.. Been told the MF2 has more load tables to refine the mapping .. Not sure ?

 

I belive the erl mf2 had 1 to 7 adjustments under the lid with little led lights ,
so 1000 to 7000rpm plus the adjustment on the pressure switch to determine what boost pressure you want it to come in at
it would or could also control the erl aquamist water injection iff fitted not this devils own stuff whatever that is lol

 

Gone for the MF2 anyway mate ..as a good friend is holding it me for a month .
