Closed Loop Open Loop fuel table/s

Post by joey »

Hi guys,

I managed to do a MAF cal successfully and my LTFT is +-0%.

If i look at the CL fuel table in VersaTuner, then I see different values like +-0.900 lambda(13.27 AFR avg).

Why does the US guys say that we should run 14.7 AFR CL and 11.8 AFR OL @WOT?

Can I set it to a std of 1 lambda? What else needs to be adjusted? Or can I just set all of the values to 1 lambda in the CL table?

I'm from South Africa btw.

Thx in advance
Jo

The lower right part of the CL tables should be at least as low as your OL tables. Do not run lambda 1.000 across the entire table.

It should taper down from 1.000 to at least the values in your OL tables. Start the transition no later than 1.0 load and finish no later than 1.313. You can see this pattern in the stock tables.
