Gt3076R Antics , Better Late Than Never .

[discopotato03]

Modified PULP map and I don't do the 4500 + . The reason the light load areas are so advanced is because that's where it seems to make best part throttle torque , on E70 . Not spiking now . I will agree the timing is mild around 1 bar but that is dyno tuning territory in my opinion . I think the PULP tune was pretty tame and until I added a fair bit of light load timing felt quite flat . 

I have heard this engine rattle twice in 10 years and 88000K so I highly doubt it'll go bang . Bores looked good at 90 and ~160K . At idle no breathing out the oil filler hole at all .

Like I said lets see other peoples E70/85 timing maps , and AFR target tables .

Appreciate that you're sharing the important bits.  Couple of constructive observations:

Your ECU interpolates between cells quite effectively.  The MAP row 95kpa on AFR target is largely redundant.  Looks nice, does very little IMO except divert attention.   I get the gist of the 115kpa row, but unless your logging shows that the engine often hovers around that point, and the fuel and ignition mapping is done to reflect/capitalise that, maybe not a lot to gain.

Similarly with the ignition map showing a row at 90kpa.  I take a pragmatic approach, and if logging shows you rush through that zone very quickly or don't actually spend "that much" time at that load point, don't add complexity to the map. Get rid of it.

You're on ethanol.  Add 3 degrees of timing across all cells from 140-200kpa (and play carefully).  If you're running decent advance sub 100kpa then quickly take it away as boost rises, it's going to feel flat.  You know it's going to need a dyno session with someone who is at least moderately competent at some point to get ignition right, across the full load range.

Run an AFR log or two, with steady accel, and then with decent throttle above 50 percent.  The data streams will show rate of change of throttle, boost, and accel enrichment + how closely actual AFR follows the target.  To say the accel enrich values "look big" could be mistakenly ignoring that it potentially needs more. 

Finally - Have an experienced driver who doesn't know your tune pedal the car in those situations, and get their honest impression about "feel" once it's tuned more satisfactorily.  It may be better than you're thinking, and over analysing the performance of an old car.

Just give it to scotty to tune! DONE!

^^ agreed.
