My 1st time ECUx logs inside. Help me learn... Stage 3 AWE
I finally got ECUx working. I ended up using the keyspan USA-19HS usb to serial adapter and a serial KEY-COM VAG cable... lemmi works with this too
A few notes:
my altitude/elevation is 6200ft.
I still have stock ICs. ERs go in tomorrow
The runs were all slightly uphill.
With no lemmi tweaks my ltfts are about +5% so I did a couple of runs with +5% primary fueling

Any comments to help me learn this stuff are appreciated.
Thanks!

Looks reasonably healthy but slow. altitude and stock ICs definitely aren't helping
ERs should definitely help a lot.
Fuel looks to be in a pretty good spot but you could play around around a little once you get the ICs in.
Timing did improve with the added fuel but it really didn't lower the fats any.

ah, uphill run too. Still, log in the same spot and post here when you add the ICs.
And don't change anything else. We'll see how much they help. Your 45 deg IAT delta will drop to ~10 degrees and you'll haul ***.

Looks very solid. It's expected to have a mid 4 FATS at altitude and going uphill....
don't pay too much attention to FATS if you are not on level ground....unless you are just using that same stretch of road for comparisons with your car only. No sense in using that FATS number as an absolute reference if it's uphill.
Your IAT delta blows but that's to be expected for OEM ICs. New ICS will help a lot.
I'm assuming that you are running 93 octane because that's some great timing considering your crappy IAT delta and relatively high boost up top (above 20 psi in upper RPMs).
The AFR curve is nice and flat and the primary O2s are where I'd expect. Your EGTs look normal (maybe a tad high but no worries). You have no EGT enrich so that's good. Nice, smooth accleration curve.
Honestly, great data aside from being slow.....but again, if you were going slightly uphill at 6000 feet that's not too bad. For reference, I was running about a 4.0 FATS with 91 octane at sea level and a 22 psi taper to 19 psi boost profile with my Stage 3 sedan.

Considering altitude and ICs, not too bad for AWE/GIAC stage 3...
Interesting that you make ~22 psi up top even at that altitude...GIAC must crank up the max pressure ratio table pretty good. What is your ambient pressure up there? With as hard as you are pushing the turbos on the top end, the ER ICs are a good idea as I'm sure pressure drop will be reduced.
