Buddy and I noticed the my injector correction values were incorrect and my logged wideband values didnt match up with the gauge. Rewired gauge to dataloggit per Innovate motorsports instructions online, which are different than those in the pdf sent with the wideband. Anyways I reprogrammed it for 0V = 9.0 and 5V=18 AFR with LCprogrammer and changed settings in datalogit. Now gauge and logged values match.

Then I changed the values to 67.0 and .01 msec of delay since I have Nismo 550's. Settings were 100 and .1msec, not sure how these got in there but somehow my car has been running on that setting for a couple weeks, just rich. Now car runs lean as hell at idle. Weird thing is that I loaded my old map and old settings, one the car was running on for a couple weeks, and still the same thing. WTF?!

Set injector correction back to the correct values of 67.0 and .01 msec. Maxed out correction (1.469) for the load cells at idle, still lean like 18 AFR. Bumped INJ vs. Water Temp values up for +30 to 1.5, and +50 to 1.25. Now idles at 13.8-15.0. Want it to be 12.5-13.0 at idle.

Is it normal to have to raise the water temp correction so much?
