altimeter adjustment affect fueling?

[lightening1000]

I was told that if you adjust your altimeter in your guage to what ever it directly relates to the fueling it provides the engine? eg if your at 2000ft and you adjust your altimeter to stay on 3000 ft but your actually at 2000ft it will run a bit leaner to think it is actually at 3000ft.. this was a statement fromt the race dept. I am told.. just wondering if im the only onethat has heard this.. I personally don't know if I believe in this because the engine will read altitude from the map sensor and don't really see how the guage numbers can relate to the ecm performance directly, it in my opinion would read directly from the map itself.. anyone??

I have heard of that also but never seen it done.

mine is done this way, just curious about it,, its set at 1000ft over reality

The altimeter is probably reading density altitude which is what your motor wants to know anyway.

Ask the dealer and snap a pic of his "oh my, you have 3 heads" look.

Does the race team ever win? Bogus info, one way communication, ecm to display

this is true I guess, confirmed it at a couple different places.. its not a big change but sometimes it is the easy way to clean up that minor stumble im told in some sleds with crappy cans on them..

I kinda doubted it to Dwayne. Not sure it makes much difference. But the sheet I sent ya did come directly from Cat.
