Can anyone help me interpret some VAG logs from my new KO4?
I logged blocks 002, 003, 012, and 031, WOT in 3rd tonight. Looks like I am running a bit lean in the upper RPMs, and I'd like to know how the MAF readings look. I don't really know what to compare them to.
The kit is a KO4, Ed M's old chip running the stock 4bar FPR and 260cc injectors.
Is running lean going to harm anything? I will email all the logs to anyone who is willing to take a look.
And here are a few more concerns, every few times I start up, and occaiosonaly while driving, I catch a whif of gas coming through the A/C.
And finally, I put in a new ECU, and the code the VAG reads is slightly different. The old one was 1.8L R4/5VT MOTR HS D07, and the new one says 1.8L R4/5VT MOTR HS D00. Anyone know the differnce between D00 and D07? Both are ECU code 8D0 907 557 P. Thanks.

Are you sure those are 260cc injectors?
The ndbw comes with 240's and the dbw comes with 270's. You can use a standard ndbw K04 chip with 270's and a 4 bar or the stock 240's with a 5 bar?
Not sure what those ECU codes mean, but you might want to check to see if the soft codes are different on each ecu.
If you want you can email me the logs and I can take a look at them. You might also want to try putting in a 5 bar fpr, but only do that if your 02 readings on block 031 are below .80

not 100% sure, i should have had them cleaned and flow tested
i found out a little too late about a shop near me that cleans and flow tests injectors. Thanks mike, i will email you the logs.
What is the danger in running a little bit lean?

my MAF readings on a k03, 1 bar chip. clogged airbox.
<center><img src="http://pictureposter.audiworld.com/143/vagplot-2.jpg"></center><p>max possible maf reading is about 180g/s i believe. most people get ~170g/s at wot.
as you can see i was waaay low.
