My J&S is pulling out way too much timing. I have it set to take out 1 degree per pound of boost (which I think is really conservative), but it still retards up to 8 MORE degrees above 5k rpms. I keep setting the sensitivity lower and lower, but it doesn't help the problem much. It won't be much longer and the sensitivity will be completely turned down to nothing.

My plugs look great, I am only running 8 pounds of boost, I have a MF2 for fuel enrichment, and my a/f gauge shows rich at WOT always.

 

How do you know your timing is being retarted that much? How are you testing it?

 

that happened to me too, it went away when i turned down the retard function. i don' t have the j&s anymore.

 

thanks for the reply. I need Hondata, then the J&S will go out the door.
