Though that may explain the switching back to petrol in the corners on my old car, but lag under acceleration only...?

Acceleration can cause the fuel to slosh too.. although the only mechanism by which the tank pickup can affect the running is through the vapour pressure at the output of the vapouriser, which we're monitoring, so I would expect any issues to be visible in the datalog.

Maybe it's just not logging fast enough?

Is it possible to have an LPG tank with baffles in ? That would prevent "slosh". :-/
None of this affects me, as my car rarely goes above 3000rpm.

I'm thinking, perhaps wrongly, that the lag increases gradually in direct correlation to tank level de creasing? Going by descriptions. Would that mean tank pressure variations are affecting the vap somehow? Or some other reason...? The two appear related?

[TheBoy]

I tried calibrating at low gas with mv6, still lags at high rpm gearchange

I think its related to pressure, but cannot see it on diags

[TheBoy]

Should say, mv6 is higher flow multivalve, elite is 4 hole

Not used elite much On gas (200m ?), but think neither struggles to cope with full bore large

The speed of logging has been discussed

[tigers_gonads]

Will do ( now i know too ) 

Thats when he gets back to me 

Thought you'd heard from him? :-?

Thinking on some more about the lag... I wonder if it's worth calibrating and mapping with a low tank contents :-/

Yes I have 
Just waiting for him to get back to me with a price for a tank and rear end kit
