Datalogger timing question

[turpdogg]

I have a 97 GSX with a 1st gen head/throttlebody, 550cc injectors, walboro 255 fuel pump Apexi SAFC, TD05 20G (machined out compressor housing) FMIC etc....etc.... Anyways I finaly got my datalogger from pocketlogger.com and during 3rd gear pulls the most timing I can get in +13 at 6000-7000RPMs. The 02 readings are at 1.00V but if I go any leaner (.98 or below) I only get +10/11 degree's at that same RPM. 2nd gear pulls I can get +14 degree's but thats still at 1.00V. Any suggestions?

WHen I did my first run I was running CRAZY rich, 1.04V and only getting 9 or 10 degrees timing so I have improved. I just keep reading peoples stuff saying they are getting +15/16 degrees. Any suggestions

What your timing curve looking like? Is it getting pulled while rpms increase? Usually if the timing advances then drops a degree or so it indicates knock, so maybe you just have to richen it up at that rpm level. Nor sure how much it would matter but do you have a fpr? Post your values.

What's your coolant temps? If it's to hot it will pull a degree. Also if the air temp is really cold.

BTW hows that 1G head and TB?

you need to get your air fuel ratio checked on a wide band o2 sensor the dataloger can not be trusted.
