Bosch LH 2.4 in most cases dont need any big remapping.
The hot wire type air mass meter and oxy-sensor can handle
most variations. With a 64Kb program how difficult can it get
to adjust something the fuel map? It has been used in millions
of European cars so used parts are plenty and cheap. This is
not Motronic with electronic throttle system and 2.6Mb
software.
