I installed my lean cutoff switch yesterday, and have a question for anyone that has installed one.
With the car switched on (but engine off) I armed the system, and when I press the activate switch, instead of the one solid CLICK you get from the solenoid when it opens, I get a chatter (like a slow machine gun) of clicks. I took power away from the LCS to test the solenoid and got nothing.
Since the engine is off (thus no O2 reading) is this the LCS causing this? I have the voltage set at 998 to check the "cut-off" abilities when I test it, but won't take a chance untill I figure this out My next step would be to disconect the fuel (N2O off) reset the switch for somthing lower, and fire up the engine and try it, but I wanted to here what you guys had experienced.
Also, what are you guys setting your cut-off at?
Thanks

 

Bump for a good question. I would like to know this as well.

 

talk to dean, he'll help

 

Where's Dean??

 

I am here! Just on the road as usual working with customers in Michigan.
Give us a ring - we will be glad to help! We had one customer call yesterday turned out to be his window switch. Much quicker this way than posting back and forth.

Well I finally got a chance to work on the issue I was having, and I think I have it figured out, so I'll pass this along for anyone that runs into the same issue.
I have a NX system(with Daves plate) and a timing tuner to retard timing, limit max RPM spray, and minimum RPM spray (3000 rpm) Well you proably guessed it, since I was checking the system with the engine off, I was below the minimum RPM and so all I got was noid "chatter". I temporarly set my mim. RPM to 0, and tested and the noids "clicked" open. So now all I have to do is test the cut off capabilities of the system.
For you that have installed this switch, what are you setting for testing, and then for your cut off voltage using the narrow band O2s?
