Ok I got the e6k working and running my car now I cant get a good idle. It keeps reving from 1500-2k over and over. And the af guage bounces to like 15.0-lean. If any half or full bridge guys could give me something to look for I appreciate it. I had a great idle when I was using megasquirt consistent brap, brap, brap ,rrrrrrrrrr,lol. Are their big differences in s4-s5 throttle bodys? I had a s4 now a s5 with the haltech.
Thanks for any ideas

Vacuum leak most likely. When the idle hunts like that, you are going from lean to rich, because the computer is correcting for a high to low vacuum, respectively. Your gauge is telling you the same. 15:1 is very lean and is a problem. Find that vacuum leak!

Some times the idle get erratic but I need to find a lock nut for the throttle. The base map is from john at PTP here is austin did for a friend of mine couple months ago. But He blew it at 17psi. And I changed the timimg to what I dug out of the megasquirt tables I copied from your old hbp maps.(when I had megasquirt) And fattened up the fuel over15psi. And pretty sure the timing is zeroed.I locked the timing at -5 and rotated the cas to the -5 mark.
