I have been working on a file for our Legacy GTB which doesn't have the overrun tables defined, So this is for you guys who also don't have those tables, as most other threads talk about adjusting the overrun tables.
So i first had a play around with the "Base Timing B" tables but didn't manage to get much of an effect even at -12 at 0.15 load cells between 1800rpm and 6000rpm (Leave 1800rpm under as normal for smooth idling). I ran a log on my way to work to find out that the car on decel and shifting doesn't hit 0.15 load that often, So what i have done is adjusted "Base Timing B and A" tables between 1800 rpm and 6000rpm at 0.15-0.20 Loads.
I have Adjusted the "Base Timing Above Threashold" table between 1400-2000rpm to -12 degrees which is similar to the "Base Timing (In Gear)" Tables on other models
I then added a bit of fuel on "Primary Fueling Open Loop" tables between 1800-3000rpm at about 9:1 AFR at low loads 0.15. This gives it a bit more of a Deep pop rather than a crack.
This setup has worked very well for our legacy, gives it some big deep pops on upshift and downshift every now and then, and when decelerating and slightly touching the gas pedal you will get a Burble and some big Pops. I tested it at higher RPMs as well and got some nice big cracks.
Give it a go and post up some videos if you can! Hope this helps.
As flat nats is fast approaching we may as well have a little convoy up to the track on the 24th November. Will be cool to cruise up with others and on the odd chance some ones car has a issue on the way up we will have people to jump in with / help if needed.
We have to be at the track to attend driver briefing (if you are racing) I will clarify the time on this but this it is quite early about 7.30 am.
I was thinking we could all meet at Plimerton Weigh station just off the side of motorway and cruise up from there.
Any thoughts? who would be going from Wellington
