ST170 checking VVT?
Had my spitfire apart over the winter to fix a few chassis cracks (now reinforced) and repair the rear after it got driven into...
I digress. Took it for teh MoT yesterday, passed OK but it felt a bit down on power. I had the engine out to do the above work, but wondering if the
VVT is working. Is there a way of checking? I mean physically, the ECU has not been fiddled with.
I Thought about setting the spark table to (eg) 20 degrees, and using a timing light on the cam pulley? would that work? Or other suggestions?
I did change the air filter from on intake pancake type to airbox with cold air feed, but I don't think that will do a lot to tuning? Seems to
be popping a bit on over run now too....
(I probably need to employ the lappy and wife to check, but after ideas first!)

Disconnect the solenoid and see if it's any different to drive?

I guess that is the ghetto test! Will give it a go..
Would like to be a bit more "technical" and see it advance and retard. Will have a look on Saturday, next time I have a free moment....
I would really like to find 2 bits of info from the ST170. The factory ignition map, and the VVT map, (though I think somebody has produced a VVT
version, ME?)

Yes it's ME - they do the VVT pro which has a map for the VVT, I'm sure I've seen it online somewhere I will have a look

Fret not, it is a ME221 ECU, and I have not played with their VVT settings. The other tuning data was a bit hot and miss, even after it had been on
their rollers  but I had got the map pretty sorted before the engine came out over the winter.
