We have a 2.0 Zetec on Triumph Daytona ITBS. The injectors pretty much fire straight onto the back of the intake valves but without geometry changes to the linkage a lot of intake area suddenly appears when you open the throttle.
The WB02 shows an instant LEAN condition (no surprises) at this point and the engines 'gasps' until you close the throttle. The fuel MAP is good enough for gentle acceleration and driving, but its only done 3 miles on the road 'between garages' (yes it was insured).
It clearly needs MORE fuel on acceleration, but roughly how much and to which graph/adder box do I drag/type a number into?
Its got a 30 mile drive (to its IVA test) on Thursday and it would be helpful if we could get it behaving a little better, not least the tester needs to drive it around a bit.....
We will be running Tune Analyze live! en-route and be driving it very gently.
