Decipher my datalog (Evoscan)
Hi,
Did a datalog last night, started off with some low boost (very rich and had some single counts of knock..) increased boost a a few clicks with the UNOS and this is the last pull I did.
3rd Gear, night @ ~82-85 degrees - california 91 octane
How is it looking?

Looks good to me. You should still have some room for additional tuning.
Whether that means less fuel, more timing, or more boost, that's up to you, but your logs are knock free and looking good.
Do you have a wideband, by any chance?
A good way to see if your tuning is helping is to log the time it takes to go through a certain speed range or RPM range in the same gear on the same road.
For example, on my Eclipse I would always log the time it took to go from 60-90 in third gear on the same stretch of road. As long as the times were decreasing and no knock was present, the tuning helped. Tune up to the point that you see some knock and then you know the threshold at that particular RPM. Back off a little, etc, etc.

looks good, you could probably advance timing about a degree or so in the mid rang where its reading 6 and you should be able to advance to almost 20* around redline. Like said above, you should also have a wideband to make sure your AFR's are in check.
Edit* just saw that you have 91 octane....maybe your timing is good then....

No wideband yet, but it is next on the list along with a walbro 255
Thanks ralph,
Thats conservative but I guess you have to for 91 octane, huh?. With that I would say leave the A:F alone (rich) and give it one degree of timing. Then pull it back to where it was in areas that consistantly picked up knock from this change.
I'm not an expert but that's what I would do.
Do you have a base flash?

I'm sure you could find out easily though.. I think the tune is great though .
Increased boost several clicks on the UNOS and got to the point where I had knock 3000-5000 rpm, lowered boost a few clicks.. now its fine. 0 knock and I've got the top end at .94 O2 (narrow)..
Ordering that wideband in a week.
