thanks joel,
am not sure of the heratige of my 1G (was transplanted from a luxo-barge into Helmanns yellow RA40 before i got it) - tho am reasonable sure it's always been Twinturbo.
i was wondering how the ECU drove the TVIS on a turbo engine - as you would really want the butterflys open once boost starts - but boost can happen a lot lower that 4500 - and you don't want to be chocking off the end of the runner while trying to spool up a turbo?
maybe there's some notes about it somewhere...

Chuck, there really is no smarts deciding when to switch over t-vis, it simply happens at a set rpm (don't know if the 1G is the same as a 4A) and if the megasquirt has an aux output, simply set it to switch the vac switch at a given rpm.
T-VIS is really a rather complicated system to get working as well as it does, unless your motor has at least bigger cams or is turbo'd etc, it would go better with the t-vis active.

The MSquirt can drive aux outputs (if you write/modify the code and install a few more parts) - tho i would probably make enabling TVIS a combo of boost and/or 4500 rpm. There's a few people hove added bits to Msquirt to turn on water injectors, fans, NOS, 2nd inj's, etc...
Charles.
