Where's your wideband log? Do you have a wideband gauge that you can hook up to Evoscan?

Apexsilver03

I do have a wide band but don't have it connected to the cable but if I'm not mistaking it runs about 11.5-12.4.

You'll need to hook it up so we can see what your AFRS arw when you are knocking

Can you just attach the excel file? That pic is blurry...

And why is the TPS jumping around?

Apexsilver03

Yeah I did some maintenance on my car tightened up some bolts changed oil. Replaced my ignition coils with new cop and started to have issues. I put back my stock coils but the car failed to start. Looked at the DTC had codes po134,po113, po107. I erased the codes to see if they would comeback and haven't as of yet. Car is tuned for e85 fp red turbo build block stage 3 head full bolt on to support build Buschur double pumper, gsc2, 30psi of boost, stock ecu, cams,br8eix plugs gapped at .020. I have double triple checked everything. I am at a loss

Its Looks like it could be coming from your timing jumping to the 20's and 30's just before the knock shows up which, as gitrdone said, could be from the wacky tps signal. Or are you actually on and off throttle during the pull?

Apexsilver03

Could the stock coils have been going bad and the tune was adjusted to those coils and the new cop are stronger and now it's knocking?

You need to solve the TPS issue and go from there. It should read 100 all the way down if you have the pedal on the floor.

Not likely. Weak coils will just have spark blowout if timing is advanced further, which just causes very noticeable misfires. Attach the actual excel file please, that screen shot of the log is almost impossible to read.

If you open in new tap and click the magnifying glass it is barely readable. I just edited it to at least remove the junk rows. Not sure how it will look once uploaded but here goes.

You get knock after your AFRMAP jumps to 14.7 (and your timing jumps crazy high) b/c your tps reading is jacked. I think this is the issue. Either that or your maps are totally jacked up.

Apexsilver03

So could a bad maf cause these issue? I have codes po134, po107 and po113. I have cleared them and they haven't comeback yet either.

Yup, what he said. Throttle position plays a large roll. If its skipping around your vehicle can randomly ask for something that should not be asked for. May be confusing, just fix it and chances are it will clear up some issues. Looks to be a bad or loose tps. (Could also be wiring, low chances though)

You need to stop trying to time this car and get these issues sorted out before you blow it up.
