Have searched to no avail

when doing a free air calibration - does it make any difference if the car has been running for say half an hour, then you pull out the sensor and do it
Vs
pulling it old cold, letting it warm up for 30secs with the ignition on, and then calibrating.

Just curious is all.

 

Shouldn't matter, either way is fine.

I personally like the method where you coast in 4th gear w/ injectors off the best.

 

^yepo that sounds a lot easier for future efforts

I took it out this time to be 110% sure i did it right.
was on a dyno last night... dyno was reading 12:1 when LC1 was reading 11:1
quite a big variation, and I'm pretty sure there's no exhaust leaks between my WB and the tailpipe.
