A nerdy tuning thread about Air temps, ingition maps ++

First, wrong forum.

 

To answer your question, you are pulling timing at an IAT that is quite low. I do not pull timing until 45 degree C. My IATs are typically 40 degree C during pulls on the street. Your timing looks quite aggressive for 180 kPa, 30 degrees at approximately 12 psi. Others (as posted on the Megasquirt forum) are running anywhere from 22 to 26 degrees at 180 kPa.

 

As for your IATs, it is most likely more a function of your ambient air temp (you said 70 degrees F in your other thread) than your IC. Most of us run are in ambient temps of 80 to 90 degrees F unless in the spring or fall.

 

Check out the Megasquirt forum, under the map sharing sticky.

Yea, the IATs cant be compared, I live in a cold country.... Thats probably one of the reasons Im running more aggressive on the spark, but there could be many. I have no knock problems, so I wont change it any time soon.

 

Typical IATs here is less then half of yours by the way.

 

 

 

Wrong forum, yea. Ill delete and rewrite.
