Yeah, It looks like a sharp transition, but I'm just following the numbers. The AFR result is very close to linear.99 at 5000 and 91 at 5500. You're killin' me man. :]
I do like how consistent your car is. Consistency is everything. It really does look like you could get the afratioest line to be on top of your ZT-3 line. That is dream^2 stuff.
I'm wondering why the airflow above 1900Hz is wonky - is that real, or is that a sensor issue? HmmmWOW that dip-in is perfect. Never seen anything like that.
Make the whole right of that the same.
Yeah there's a bunch of stuff getting all zig-zaggy towards the top end of the pull. Sure looks wrong.I'm wondering why the airflow above 1900Hz is wonky - is that real, or is that a sensor issue? Hmmm
Its in the raw maf data, but I also see some instability in the map data.Yeah there's a bunch of stuff getting all zig-zaggy towards the top end of the pull. Sure looks wrong.
Looks pretty familiar. 5000 rpm is where my AFR hits its minimum (lowest spot on the curve) which is about 11.0 with about 11 degrees of timing, and there won't be any knock there but I might have 0.4 deg of knock retard on the run-up to it, like at 3,000 or 4,000 rpm (like you did) for short bits. Above 5,000 rpm my AFR climbs to about 12 and of course timing goes up too.E25 is responding well to 11, and I can see the knock sensor is starting to wake up.
Yes, there was a barbed fitting screwed in here with a hose to the GM3BAR sensor. I want to make a direct comparison of the data with the new sensor to see what is the what.Was your other sensor directly into the plenum like this?
