Jim, the Thundermax doesn't use the MAP sensor. That it's "very beneficial" is really less so than it's just different. Going from a speed density to an Alpha-N box changes the need and utility of the MAP sensor. The ion sensor on the other hand would have the same utility for the Tmax as it does for the stock system; if the Tmax used it. Which it does not.
Yes, it's the Ion sensor capability lacking in the TMAT that has me looking elsewhere, Don. The TMAT is fine around here, but I know when I get to a v. different ambient environment, it pings. And I don't like it.
Granted, the ion sensor adjusts over a relatively narrow range. It's sort of an uber VOES. But it's still the only thing on the bike that can do that job. Zippers (apparently) trusts their maps so absolutely that they believe that their shi... oops, I mean that their system just can't ping. Obviously what you heard and what I heard and what others have heard were psychotropic halluncinations rather than actual engine noises.
Either that or a small team of leprechaun blacksmiths, all battering the shoot out of their mini-anvils with mini-hammers, inside my motor.
But switching to this device has another couple of useful things; - back to the standard ECM, good for warranty, (first thing they tried when my motor gave up in Spain last year - 3rd party ECM? No warranty! - they hadn't realised at that time they were talking like that to the wrong guy!), good for the HD Techs to connect to for fault diagnosis, etc., back to the narrow band O
2 sensors, which fit better with the V&H headers....
So, what's your take on it Don? Sound like a useful device to me?
Jim
