Hi all,

Looking for some feedback on these maps, especially regarding if they are good for a 1.6 NB. Don't want to use VE Analyze if the AFRs are sub-optimal. Have tried to look around, but having issues finding sources for 1.6 NBs. MS2 PnP, stock except for a full Malian Exhaust (cat-delete) and a "cold"-air intake with a K&N filter. Apart from the tables, any other important settings for the 1.6 NB Miata I should double check?

 

I don’t think many people tune the 1.6. However it’s just a BP, the same theories apply. It’s not a drastically different engine in any way that matters.

that being said, your AFRs are rich, your 31 or 38kpa row could be put at 100kpa and you’d be fine.

same with ignition, your 52kpa row could be made your 100kpa, I’d just interpolate from 2500 to 5000 to get rid of the high spot.

 

I see, thanks for the feedback. It's really appreciated.

1.6 NB is by far the most common one in Europe, but apparently there's not that many of us here on the forum regardless.

Should add I'm mostly on 98 octane, but sometimes on 95 octane E10.

I copied those tables from a thread staring they were OEM and translated from Japanese, but I assume going all the way to 128 kPa for N/A is a waste of resolution?

Also attaching the tune itself. Don't have my computer in front of me, so haven't had the opportunity to change the tables yet.

Do be aware that octane levels in the EU are different then US octane, our 93 is around your 98 for example. So consider that when looking at timing tables as well.

EU uses Research Octane Number (RON)

US uses Anti-Knock Index (AKI) with is average of RON and Motor Octane Number (MON)

 

Yeah I'm aware, but thanks anyways.
