Steve Kan was here this past weekend tuning some Las Vegas 7's.. Sunday we had a issue with my 20B running lean around 4800 rpm (made 250 RWHP @ 5psi and 4800 rpm) . So we took it off the dyno and drove it to my house. We pulled the Jegs fuel filter and it was clogged with a lot of junk. Removed the filter element and installed it and took it out on for a street tune... Did some 4th gear full throttle pulls and @ around 5800 rpm the engine would stumble.. like it was hitting fuel cut.. We stopped for the night and continued Monday afternoon around 5pm.. We went to eat at boulder station and i was looking at my ignition module (it's around 5" X6" box) and when I touched it the box was real hot. We unplugged it and let it cool while we went and ate.. After we got back in the car we decided to give the street tuning another shot. To our suprise the stumble was gone. We got on 95S and did a 4th gear pull and no issues. Did another pull and no problems. On the 3rd pull it came back. We are thinking something is wrong wih the igntion box when it gets warm. Will call Link ECU tommorow and try and see if they can check out the box for me.. The 4th gear pull was real sick.. I'm gonna keep the twins until the winter when a single GT42R gets installed with a E11V2.. Thanks again for all the support for this event.. Thanks again Steve...

 

A few people had similar issues iirc with the AEM box.

 

Do you know what they did to solve the issue?

 

what about additional cooling of the box?

fresh air duct? perhaps some sort of heatsink?

or opening the box cover?
