Major problem with my log *Please Help*

Went out to do my first log with EvoScan and came across an issue. This is on the factory timing/fuel maps. When on WOT I have TPS, Knock and probably other issues. Heres my TPS and I attached the excel log also. PM me please.

what settings? and could this be caused by a low octane? i let someone else drive my car and they might have filled it up with something other than 93oct.

TPS is bouncing all over the place. Was your foot planted during that pull? Absolutely no lifting? The latter part of your log (4000 RPM to redline) has the look of someone fluttering the pedal a bit. Ask a friend to watch your foot during a pull. Yes, I'm serious.

As for knock: you're logging knock voltage rather than knock sum; scroll down in EvoScan, uncheck "Knock Voltage", and check "Knock Sum" instead. That'll give you the values you're expecting.

Edit: as for cause? Could be any number of things, and I've seen knock on the stock maps before. It could certainly be a batch of bad gas; you could toss a can of toluene or xylene (from the hardware store; in the paint aisle, typically) in the tank to see if that helps, if you just want a cheap octane boost until your next fill-up. If you're sure it's good fuel, you might consider pulling timing a bit in the ranges you're seeing recorded knock.

restart your laptop and make sure the usb cable is plugged in before you fire up evo scan...
Do a datalog and check it before you go out and waste your time.... Mine did that a few times and I was like **** have to do it again...
I'm running Mitsulogger

the most recent thing i added were spark plugs. if they mis-fired would it cause the tps to go crazy? and when i was driving earlier this morning i hit a bump and for a few seconds the throttle didnt work either... any ideas?

Pop your bonnet and check your tps its on the throttle body on the firewall side. The retaining clip night not be there or the plastic is cracked (loose fit)
