Default Thundermax AutoTune owners



The rest of you Tmax owners may already know this but just in case there is someone besides me that didn't know about
thisspecific step you need to do to turn the Decel fuel cut high and lowfeature on. You have to turn onthe Decelfuelcut highand low feature bygoing into Basic Settings under module configuration in the tuning maps section. In the Basic settings window justabove theDecel Fuel Cut Rpm low box is the box Decel Fuel Cut with a 0 in it. You need to click on this box and replace the 0 with a 1. The Decel Fuel Cut Low and High is now activated.
Prior to discovering this yesterday I kept getting decel pop at 2500 rpmdown to 1900 rpm since I installedthe Tmaxlast Feb.I kept changing the rpm numbers in the Decel Fuel Cut High and low boxes butit just didn't seem like that did anything that I could tell. I had the updated software and firmware installed at Sturgis last August so It only took me 9 months to furgure out it wasn't eventurned on!!!!!!
Anyone else out there that didn't know about turningthis feature on?

I did'nt know that, I plan update the firmware very soon maybe I will do it tonight.

I never had a problem with decel popping though, milage is not the greatest getting about 35 mpg, was hoping to get a little more out of it.
