Hey guys,
I own an '03 OZ-Rally Lancer, and I've recently begun to dabble with ECUFlash and EVOScan. I haven't modified my stock fuel or ignition maps yet, since I have an AEM UEGO on the way which will have to be installed before all that. Anyhow, my issue is that I used EVOScan to record a few data logs. I did a 1st through 3rd gear pull in 3 of the logs.. two were on a flat highway, while the 3rd was going up a gentle graded road. Another was a 3rd gear 2500rpm - Redline pull. So, the car is on stock fuel maps and tuning with the following power train modifications:

-CAI
-RRM Headers
-Magnaflow Catback
-DIY Urethane'd front engine mount

There are a lot of other cosmetic modifications, but I don't think they're relevant in my inquiry. The problem I have is that in the data logs, I'm getting Knocksum as high as 11 in some areas, and pretty high Knocksum throughout the whole powerband. I've posted my data logs below, I would really appreciate it if someone could look/play them through and give me some feedback on if they think it's phantom knock, or if something is really off. I've also posted a screenshot of my fuel and ignition maps if that helps.

Any feedback would be greatly appreciated.

Thanks.

 

interesting? Is there a reason you were not 100% tps?

 

Yeah, I thought that maybe my throttle cable was too loose, so I checked that today and indeed there was some slack. I tightened it up nicely and took some more data logging runs. The TPS is still showing 96.07843 when I have it floored. I've heard that EVOScan may not always show the 100% reading, so I'm assuming that is the problem. The data logs I took today are a lot better for analysis as well... I took 2 readings of a 4th gear pull from about 1500 RPM, and a 3rd gear pull from about 2000 RPM using 87 octane fuel. Luckily enough, I needed to fill up after those runs, so I filled up with supreme 91 octane and did the second set of runs. I'm still getting knock, but not nearly the amount I was getting during my previously posted runs from the other day. I did the runs today on a smoother highway, so maybe that can account for the decrease in knocksum readings. Anyways, here are the logs... and please try not to laugh too much at how hard the car had to work in order to reach redline in 4th

Thanks a lot.

 

that tps number is about as high i could get with a 0-100 run. Ive got a .5 mi. freeway onramp thats pretty flat so i just ran it like a 1/4 mi. run up to 100. Also my knock sum got up to 14! I was trippin about it but other 3g drivers on my forums see the same knock sums. So... what can i do

Any opinions are more than welcomed.
