What about cranking tables, cranking base pulsewidth etc, opening times vs. batt voltage...
I'm getting 0.070 for Displ/flow?

I'm 98% sure I got help on all that and. Was adjusted to suit larger injectors. Car fires up easy no matter if hot or stone cold etc.

I would double check. If this is wrong, all the other figures are fudged to suit...
Check the scalar in TP
That may explain richness...

This is from 2 days ago so ve map is slightly changed by maybe 1 or 2 %
Car drives good afrs are pretty dam good all round.
only time i see it mega rich is like i said when i stab throttle when car is cold. in neutral
Also i have knoticed when warm and slowing down coming of throttle it goes rich around to 12.5 afr
Not sure if both these problems due to a part of the ve map that the car goes into when slowing down coasting or
free reving in neutral with no load on motor ?
I see there is a deceleration enleanment ? part also in the tune. Is this like a enrichment on slow down ?

You will need to post your boost VE table. Maybe post boost A/F as well...
That transient fuel is under 'manifold fuel'. It may need adjusting

The 82 VE max doesn't look very high. You could probably do a little more on the A/F as well, maybe 11.5-12.0?

I know ve map does look a little low in the numbers department
Only up around 150 kpa as standard boost and probably conservative on the timing also as on 91 fuel only.

The VE scaling is relative to the set injector rate. You can adjust the injector rate and resize the VE according to your liking.
