AFR tables?

[MrBill]

I got this from infector944
240 12.0
200 12.2
150 13.0
120 14.2
100 15.2
85 15.8
65 16.0
40 16.5

I'd like a more detailed table that i could plug into megasquirt and try the ego/autotune function.

Does anyone have a target afr map? Or a guide about how to phase this one in?

search for posts by kyle242gt... he had a fairly detailed afr target table posted at some point.

I wouldn't run that lean in the 100-120 range, ever. Even on an all motor car you tune to 13:1ish at 100kpa. I'd bring the 150kpa range to 12.5:1. 120kpa to the same, and the 100kpa to 13:1, 85kpa to 14.7:1 and then lower then that you can go leaner for cruise.

You can run leaner in the cruise range but only if your motor likes it, and you add timing to suit.

Your best bet is to drive around with the afr map open and see what driving conditions are at what load points and then adjst your table to what seems 'smart' there. Low load, stoich or leaner if it can take it and emissions aren't an issue. Med load, stoich or just richer. Full load, rich, rich rich, until you can dyno tune it leaner safely.

i have issues with running leaner than 15.5:1 on the highway, the car likes to buck and jitter and such. that may be due to big injectors not wanting to shoot just a little bit too. At 100kpa, i presume you're wanting to speed up and not caring about economy so you can richen it up and get some more power there, at least 14.7 at 100kpa. the on boost stuff looks good, just as long as you can ACTUALLY get those numbers off your injectors is the hard part(if you're not running some sort of larger injectors).

I ran upto 17:1 on the highway without misfire issues. The car gets best fuel economy around 14.6:1 - 15:1
