I meant if you gad the 143 updated and mapped cant imagine be any real different between that and a 160

the main difference between the 145 and the 160 is the cylinder head and valves a remap won't simply bridge the gap.

Also remapping a NASP stock engine is fairly pointless anyway as there will be fairly small gains. Would be better off with fresh fluids and a filter change.

with the VVC engines you can "Lock" the exhaust cam to a specific profile and there is some info out there on this.

How is it possible to lock the exhaust cam when the VVC is on the intake cam?

Indeed this is a very good question...


I meant inlet

My MGF is a mk1 so runs MEMS 2.0 which isn't remappable. One would have to convert to MEMS 3 which isn't that difficult but does require some effort.

As above, there are some mechanical changes but there is also an updated management system.

As with any mapping, it isn't just about the headline maximum BHP, there is more drivability and the map can be written to suit any alterations within the mechanical package.
