How does my Lambda target table look? What would you change and why? I also attached my spark table

99 Miata Fully built turbo 1.8L 12psi (being relatively conservative due to driving this car daily currently)

Hi,

The AFR table looks a bit rich at the top, could be at risk of bore wash there.

have you had it in the rollers and tuned AFR to peak torque?

The timing map looks a little high in the low load areas but this is common in OEM’s and not really necessary for performance. I’d expect to see peak timing around peak torque with a ramp in ramp out either side.

Hi, depends how "fully" build your Miata engine is? Different pistons, CR... etc.?

But still, the AFR table is a bit too rich for Miata boosted engines...

...roughly from 120kpa upwards I would bump those afr targets up by 0,5...(no real reason for going sub 11s in 5000rpm with 200kpa)

Hard to give real pointers for the ignition map without knowing your setup more, but still it looks to me, like bad scale of load axis... eg.: 80kpa ignition line really should be 100kpa etc... Which is kinda usual for ME221 "base maps" and going from that (also after sw/fw updates it used to mess up some tables back in the days...) as far as I remember...

So, would say, your calibration overall could need a bit of rework ;) (with more info also on the setup I could elaborate more)
