Anybody here had any problem with the HMF burning up the ECU? Or any other problems that I may not have encountered yet?

I would think it would be hard to prove their unit cause a malfunction.
They would just have to honor it on your word and most companies aint that cool.

If there is any sign of the unit being wet then they will not warranty it. The warranty is only for a year anyway.

That is the truth, so I guess what I am asking is will the Grizz run as good with out the programmer?

Im thinking no, since it's EFI. The programmer should be what is making the air/fuel mixture right w/ the aftermarket exhaust and snorkels. Unless its different than the brute. I know the brute wont.

Only thing I would say is make sure you are not running too lean.... Overtime it will cause premature damage on expensive parts.... Heck, way too rich will too...

I hadn't heard about the Optimizers doing things like that, but it is possible...

Typically snorks will richen up the mixture a bit depending on the amount of flow compared to stock... And of course your pipe will lean it, so alot of times you are back to a GOOD mixture.... MOST times.. Not all...

A friend of mine has a 02 sensor to put in the exhaust to tell how the bike is running (rich or lean). And I did some research and found out that I can change the air fuel on the display with the on board diagnostic program. What do you think, good or bad idea?

Yea man, especially with the 02 sensor. That is nice to be able to do that on the display.. I remember reading about it and saw a video on it also when they first came out that year.
