Jim.
Iīm biased as we at the shop convert 16Vs by the bundle.
We use a european system developed mainly in Sweden by the name of VEMS.Manufactured in Hungary.

Similar to the MS.

Results that can be had is better than fair to be honest though.

Thatīs the dyno run of my friend Johans 2.5.
Put a 194.7 to the rollers on the KE.
By converting to the VEMS...226@7000rpms.
Atop of that mileage has improved as well as the dynamics of the engine(throttle response aso)

Those numers are not the end of it though as Johans bottom end is so worn itīs beyond explanation.You could do your hair at the crankcase ventilation.

What you might need help with from someone like me is the config and adjustments.My advice is to ad the cost of a dyno session to the conversion,and spend time getting accustomed to the software to be able to play around with it.
System is wideband O2 controlled,which leaves you with a resolution the KE could only dream of.

Btw.
Mainly due to the WB control of the system Johan passed emissions over here too.
Limits are 0,5%CO and 100ppmHC coupled with Lambda being measured at elevated revs(2500).Has to be between 0,98 and 1.03.
WB will make it all happen,as you can adjust even the time elapsed for the closed loop to take effect.

There are differences between the VEMS and the MS though.
One of them being that the VEMS can be had ready built directly from the factory.
Likewise the processor of the VEMS is claimed to be more capable.
