I don't really know exactly how it works. I have the crane Hi-6r and I have it set right now at around 18*. What do people usually have it at? What does the red light mean when it goes on? Does it usually go on? I just need to be laced up on some "timing game." Thanks.

 

Right now I think you have it set to pull way to much timing. The way I understand them to work is that they pull timing per pound of boost. For example, right now you have it set to pull 18* so that means when you hit 1# of bost your having your timing being restarted be 18* and when you hit 2# of boost your taking away 36* of timing and it goes up from there.
I think you said you were running the 6# pulley so I would set it at like 2 or 3 degrees of timing restard and if you get detonation I would go up from there.

 

the Boost Timing Module - has 2 scales on it - depending on how it has been wired up.
In scale - the 0-20(i think) is a flat numbers of drgrees or retard that twill be put in at all levels of boost

the other scale - which you may or may not see depending on model - runs from 0-5 and removes boost in a progressive mannet - ie if set on 2 it will remove 2 degrees at 1# of boost, 6 degrees @ 3# and 12 dgrees at 6#.

this latter set up work best for our applications.

Note the 2 scales overlap each other so if you set it at the end value 20(?) then that would be 5 using the progressive scale and 10 would be 2.5.

I usually have mine set up to remove 1.5degrees per # of boost.

The red light means that the BTM has been notified that there is boost present and is applying retard.

 

Well how is mine set up then? I'm even more confused now... I wired it just like the Vortech manual illustrated in the wiring diagram. Am I pulling 18* total or 3* per pound of boost?

Also, the light means its retarding timing and that the MAP sensor is detecting boost? It doesn't mean that it is pulling timing as a result of knock, just that it is pulling timing in boost?

 

it has nothing to do with knock - your pulling timing in response to boost and I'll bet it's pulling it progressively as I laid out.

that is 3 pre# of boost - if you were pulling 18 per pound the car would die
