Tuning Guru's Need Held with OLFA and Temp vs. Map Table
 
How does this work with Temps?My Car is flooding out with a coolant temp of 44 degree's and at 48 degree's is fine.Which catagory runs this area?Is it the 50 or the 32 Degree rows? Thanks much appreciated ....

The PCM only knows how to interpolate linearly...so you take the data from the 32* column, and the data from the 58* column, and you'd make a linear regression that goes between the two. Unfortunately, it linearly interpolates vertically as well (down the column in addition to row to row), so you will basically be skewed by the data that surrounds any particular cell (hence why some people like to smooth their data).

By flooding out...how rich are we talking here?

I am at 11.34 at cold start up ,I dont have a 58 column,Mine goes from 14-32-50-68 so at 44* it would run of the 50 column because it's closer or the 32 column?

Ok Just tried to start car after sitting in in 30 degree temps.It fires right up and as soon as I take my hand off the key it dies.Coolant temp was 43 and the car didnt want to start,Floods out and my AFR was 7-8 and was flooding had to clear flood to start.This is a 408 with a Openloop tune.Never had troubles until the 40 degree temps arrived....I tried to down scale the OLFA table and NO dice.
