Hello, I am new to the Haltech world. I have an e6x running a to4r FC. I have a good base map. Car started up on the first crank (new engine too) ran good first start up and first drive, very impressed. Now the car was inside the warm shop for the last six months. And last night in my garage it got to around 27f. The car started up fine and after a minute the engine flooded. Had to dry the plugs and finally got it to start. Had to keep it at about 2000rpm until it warmed up. Then ran great and started great all day.

After looking at my fuel coolant correction table, I noticed it was on the rich side until about 60c. I actually just started up at 60c and no problem.

0c.....60%
40c...38%
60c...18%
78c...0%

I am going to take some fuel out before I startit tomorrow, so I don't have another exciting morning. Haltech gurus let me know if these % look good for cold start.

Thanks

in my experience you just have to play with it until its right, as the correction depends on the rest of your map. (if the map is lean, you need more correction) i do try to have the lowest corrections i can. also the factory is in closed loop (ie no correction) by 65c

Cold starts and compensation maps are usually a trial and error thing to sort out, the base calibrations that the compensation maps that come with the base map are close, but not perfect, and some tweating is always needed to get your particular car in your particular area/altitud/country to work right.

Use the wide band, listen to the engine, you will hear it be happy or bog if its not right.
