A friend of mine payed for a custom street tune and this is the log that we got in 3rd gear. He does not have a WB so I dont have is AFR. The tune was done with a WB.

If I use the ecuunlocker that MJ made can I reflash the ECU back to stock?

 

Wow, that's pretty bad. I can't believe some tuners actually get paid to do that.


Eric

 

Wow. That thing must be really slow with that much timing being pulled. I wonder why it is unable to handle 2* of timing at 3500 RPM. To see that much knock with timing that conservative the car must be running very lean. It's possible that the tune was bad to begin with, but it's also possible that part of the fuel system could be malfunctioning leading to a lean condition and excessive knock. It's just a bit shocking to see a knocksum that high with timing that conservative.

Yeah, that's very true. The timing is pretty conservative. So, there must be something else going on here, most likely a lean condition as you mentioned.

The only other possibility, without seeing much more data, would be the knock sensor picking up noise from something else.

Were there any other mods put on the car after the tune? Any reflashing/tweaking?


Eric

 

I dont know if he did anything after the tune. I just logged it for him last night and almost **** my pants when I saw the timing and knock. I will get it in the garage this week and check it for leaks.
