AFR idle lower than 14.7

BossJ

Hey guys,

So just Question - I’ve got FI test pipes and a Greddy exhaust on my 2016 Nismo 370z and I seem to be idling lower on my AFR than I should be? Or maybe it doesn’t matter.

Im idling at 13.8 - 14.1, which is what I’m cautious about. No other issues.

I talked to Seb and sent him some logs - he didn’t think anything of it - but said you can always check for an exhaust leak.

My AFR WOT is still normal - above 12.5 to 13.5 (May dip a BIT lower but so hard to tell when driving it)

Thanks.
