So I finally got the wideband in the car, and the laptop working to log, so I did a few passes today. This one is in 3rd.

The mods on the car are just an HKS RS intake, DC Sports downpipe with cat delete, and Fujitsubo exhaust.

Now for my question: At certain points in the log, the load is hitting 260ish, and according to my ECU ignition map, the timing is supposed to be -1, but according to the log it's 2-3. Is that normal? Other than that, it definately looks like I'll need to kick the timing down in a bunch of places to fight that nasty knock!

I was really shocked with how good the A/F ratio was for being a completely stock map, with the exception of a lean bump I need to fix at 4000ish rpm (I'm guessing that's actually from about 3500ish rpm, but the lag in getting to the 02 sensor makes it show up later, so I'll have to play with it).

Any other comments are appreciated!

 

Your intake can mess with the MAF readings so the load can be off.

Knock looks normal for running a stock map.

 

Is there a way to correct that? I know you can scale the MAF for closed loop.

 

Rescaling the MAF would be the fix, there's a couple of threads on the subject.

 

I'd go after those spots that are leaner than 11.5 first with some fuel and see how the knock behaves after that and go from there
