4age 20v trigger problem

[ericsiewkk]

i installed an atom to 4age 20v blacktop as follow:

trigger 1 - NE
trigger 2 - G1
ground out - G-

i cannot get an rpm reading in runtime value. trigger 1 error counter increasing every time i crank the engine. this is the trigger setting i used.

trigger mode: multi tooth
trigger 1 tooth count: 24
trigger 2 sync mode: cam pulse 1x
trigger offsetL: 0

could you post your .pcl file so we can look at all the trigger settings? 

I believe you may have over looked something as those numbers and settings you listed should be correct, but the offset will need to be adjusted once running to make sure the timing is syncd.

I have a 20v with a Link Monsoon running in my garage.  I also used G1 for my trigger 2 - I had to add 360 degrees to my trigger offset (G1 seems to be TDC exhaust, but no big deal +360 is all you need).  Give that a shot and yeah, post your config file.

 

Also, your arming threshold voltages are too high.  At 0 RPM use 0.3v, at 1000 use 1.0v.  maybe 3 at 2000 and 3.5 3000+.  Might be lower for you but this is working without trigger errors for me,

Thought of arming threshold.

Krohelm, he has an issue with trigger one.  Even if you have an issue with trig 2 you will still get an rpm reading.

I had trigger 1 errors until all of the mentioned problems were addressed.  It's probably just arming voltage on NE and maybe 360 degree offset due to G1.  Config file would help reduce guesswork.
