The reason for wanting to target tune
So....Iíve built a 110 and all is fantastic except for that little problem of being able to get someone competent with powerVision to tune it right. Iíll condense this story to the very short version. My usual tuner....crotch rocket and stage one harley, wasnít skilled enough tuning with kpa to make it work without adding a piggyback to trim-110hp 120tq felt amazing but too hot in the cruising area 275-280. Fast forward two months get some pinging in two spots on super hot days high load conditions. Go back to utilize my free retunes and he cleans it up comes out at 113hp 123tq but still HOT in cruise areas even after I asked him to cool that bitch down. Ran amazing though until I got stuck in Jackson,WY at a crap load of stop lights on a 90+ day then immediately climbed Teton pass and guess what, pingity ping ping ping. So I call my Pal Smarty and as always he had some advice for me and got me cooled down for the ride home and then I found what I thought was a competent PV tuner.....nope. Came out at 104hp and 115TQ(which I really donít care about I only give these numbers for reference) great on the bottom but lacking in top end and hotter than ever in the cruise area, saw 289ET after I left.
Does anybody here know engines and read PowerVision that could look at my background features in the map and see if thereís something that stands out? Timing should be Tits! AFRís are questionable. Seems like something is just not right. Shouldnít be running this hot cruising on the freeway.
Not looking for advice on changing engine parts. This is a build thatís been proven,multiple times, to make 125+hp 125+tq and run cool with a good tune. Iím thinking the first guy adding the piggyback made a PV switch change and the second tuner used the same base map to tune off of so he couldnít get things right either. Any help would be greatly appreciated.
PM email and Iíll send maps out. Thanks.
