Momentary Small Lean Spike at VTEC Point
Posted: Thu Jun 30, 2022 2:55 pm
Hi Folks,
I've got a small lean spike in WOT when I hit the VTEC point.
It's small but it's annoying me in an OCD sense. I'm not seeing a loss of performance but no matter what I've tried, I can't seem to tune it out.
The map is giving sensible WOT AFRs between 13.1 and 12.7 (I've aimed for about 13.0)
<VTEC>
It goes 12.6 13.6 12.8
I want to know, is there any way to tune it out, or should I just ignore it ?
Car is a swapped MR2 Spyder with CAI/Cone Filter & 4-2-1 Header. Stock internals EP3 K20A2. WB is an AEM-X.
Datalog, Map and Photo of the Graph attached.
Thanks!
Also if anyone's bored and wants to review my map, I'd appreciate that. It's a road tuned map I've prepared for pleasure/experience before I swap to an RRC intake manifold and spend money on dyno time. 50 degree cam at 4500 because it sounds so good.
