ECU or PCV?

[Steel]

2012 R3R
Pipercross intake
Carpenter Brute Pipe
PCV with AT.

Took it in for a dyno run just to see what she was doing.

It seems to pull pretty much the same in 3rd and 5th gear. It has a little stumble in 4th at 5750 rpms.

I was wondering if anyone has any ideas.

The A/F map in the PCV/AT is just one map.

The Tune ECU has the same map in all gears.

I'm at a loss.

were you using my AFR Table map?, I notice on the AFR tabvle below the runs that it runs a bit leaner up higher give me a chance to do up a nother one and I will make it richer, I feel this is why it was not quite right at 5750rpm ...... I will get back to you

Yes it's your map. I just don't understand why 4th gear is acting different than the rest. The PCV should be tuning all the gears the same.

It probably is but the gearing will effect the end result out the back also why the dyno guys usually tune in 4 gear, when I get home I will work on a richer AFR version, am currently testing version 3 for the last week now

I'll be looking for it.

4th is normally used as it's direct drive and least amount of loss through drag
