The cars at 15psi with the mods in profile and this was the first time with the datalogger and 550's. SAFC settings are hi= -10 across the board lo=-5, The guy that was helping me tune it was a local guy from autocross with a 450ish hp 2g, so I assume he knows what he was doing. He said that I may be able to lean it out a little bit more, but we had ran out of time. All runs were in second gear due to his preference.. (idk either..) Let me know what you think. Also how do I read .dat files? WTF Thanks for your help guys. :thumb: Edit** I just read that usually the correction is -18 for 550's and they say take out 10% just to start and lean from there. Am I really rich then?? He said that my timing was good. I am really wondering now. The car definately feels faster then before.. though

I would taking 10% out would probably be ok. It says in your profile that you have a "blinky light 02 gauge". I assume that means you have a narrow band O2 gauge. I would ditch it and get yourself a Wideband O2 if you really want to tune the car correctly. Also it would probably be better to tune in 3rd gear since it will put more of a load on the engine. Good luck.

The blinky light air fuel gauge wasnt used at all tuning the car. He was using OBD-II.com software with the OBDII interface. I understand using third gear as it will affect the load. He said that he wasnt sure about the area. I am wondering more whether or not the car is fairly rich. A friend was following me around said that I had black smoke coming out of the exhaust and then I mentioned that he said I might be running a little rich. Then I saw the 18% correction figures and it got me wondering. Thanks for your help :thumb:
