Default Logged some vag-com runs...do these look normal?

<center><img src="http://pictureposter.audiworld.com/143/vagplots-1.jpg"></center><p>Conditions:
Car warmed up, 61F ambient. Wett 1bar chip, 710N installed "reverse". New DENSO K20PBR-S10 "stock" plugs. 93octane, some techron still in tank.

On the 3rd gear WOT run, does the timing look right? It drops steadily...

On the full run, i think is slow shifted at the end of 3rd, perhaps that is why there is a blip there...but does the actual vs requested look ok?

TIA

I think the timing looks ok, but I think the MAF readings are low

Default not 100% about it.....

but I'd say boost looks ok...but the MAF should be over 150 for chipped...I think your MAF might be on it's way. Let's see what Audi2ptzero and others that know better say.

Default ok...yeah i have a 1bar chip, so a 2000mbar reading is perfect.

i did some searching...and i think you are right about the low MAF readings. I'll repost for the day crew tomorrow.

Default looks low

1 bar is probably enough to make a good 150 by 6000 RPM's. If you extrapolate that MAF graph out just a bit it looks like it would be at 140 or so at 6000 which to me seems lower than it aught to be. I think a stock car will show that much.

Timing looks like it's getting pulled back too much.

Default Re: baselines..

I need to get out there and just do it.....but I keep putting it off. Anyways, I have a stock ECU and a chipped ECU....plan on logging a few parameters. Will let you know how it looks.
