Can anyone tell me if the stock EFI unit of a 2002 ZL 600 has an ambient temperature limit in the mapping?
Thanks

i'm sure it does, but unfortunately, you have to call cat to find out what it is. that mapping is in the now unreplaceable E.C.U. chip, in the now sealed E.C.U. there isn't a book or manual out that will give you that mapping. all the E.F.I. sensors will read from -40f to 220f. my question to you is, why do you want to know?

Just want to know if the ECU will handle the Texas heat!

what do you plan to do with it. i might have a better responce after i find that out, but the one thing i think of first is it will be pig rich.

The engine is going into an ultralight aircraft.
