EI is a good company. I have a GRT EIS4000 engine monitor which has "set lean point" function that assists in leaning. I think it's way less money than any other engine monitor and works well.

George, it seems to me that althought the EIS 4000 can be used for LOP operations it does not in fact have specific functions for LOP operations (only ROP ops). In other words it does not have a page dedicated to LOP ops as has the EI equipment and a number of other respected engine management systems. This would seem to bring into question GRTs website claim to have the most "comprehensive leaning functions - the best at any price".
I would imagine that it would be preferable for LOP ops if the EIS 4000 had several specific LOP functions including a settable EGT range for all cylinders to run LOP. An alarm if any cylinder deviates from a specified range while running LOP would also be very beneficial.
I like the idea of LOP.....clean, cool, and just sippin' fuel. But as you've pointed out, if you want to do it you've got to do it properly. And it may be that the EIS is not the optimum management system in that regard at this particular stage (although I'm sure that with a bit of extra software code they could easily come up to par).
What do you think.
