the chip is like VIAGRA for the M11!! 1/3 more cap in wheat.. the RPM sits right @ 2200 , doesnt bounce around . you can pull it down to 2100 but you have no reserve left ..(You have hit maxium Q there scotty ) the temp gauge came up slightly (low green)fuel consumpsion per acre went down!!!! I cant say that for a Chipped 9760 JD I ran with. You could pay a driver very very well on the differance... The BIGGEST FEAR the JD owner had wasnt his sample or his over loaded shoe, but this,"dont let that silver S O B pass you" !!! Well guess what he said "wait untill tonight my Jd is a real dog during the day... " I dont Know how dark it had to get but the silver S O B didnt get any slower. But to be fair, the JD could unload into the semi and get back into the hunt quicker ... UNloading auger mods anyone ? EVEN if you donot chip your M11 the Best single thing you can do for any gleaner is to SPEED UP THE CHOPPER / IMPELLER !!!!!! This will get rid of any "rumble" you'll feel ....If you dont belive it look @ your cage, is it bluged ?? IF it can't get rid of the straw out the end it'll try to force it out the side thus bluging your cage.... And replace worn pulleys even if "well they look ok " that drive the chopper and accellerater rolls keep them new... these are the hardest working pulleys on the machine.. they have a very important job to do ..... Next,The r 72 I have is 98 WITH a m-11 cummins 330hp it kept loseing power after round or two . replaced the fuel rail pressure senser in the head{ the thing that you ll plug the chip into, yup its that easy}..the combine ran great until the tech went out of sight then it died . dead ..." what the f#*k???. a 500 $ serice call didnt fixit ,so dig, ten minutes later
the problem was found in a corroded fuse holder thats located below the engine / outside next to the return elevator. This circuit controlls the fuel shut off solinoid . I hope this will help if you have this problem. I also have a precision rotor from pfp sherwood nd call and ask for mike 701 459 2228 he 's the answer man. Remember there are no stupid questions just ones that arent asked.. GETTERDONE
