Mr. Dynojet - PC III Map for 1999 FLHRCI with MM EFI

[Boz727]

Mr Dynojet, I am finishing the install of PC III and AN Big Sucker and can't seem to find a PC III map that is close to my set-up and hope you might be able to help. I have the following:

1999 FLHRCI
Stock Twin Cam 88
Magnetti-Marrelli EFI
Stock ECU (as far as I can tell)
Stock Headers
Hooker Tuned Flow Slip-ons biased to "H" (horsepower vs torque)
Arlen Ness Big Sucker AC
PC III

Thanks in advance for any help you might be able to provide

Try the M802-312 map first and let me know how it works for you. With some feedback from you I may be able to make some suggestions if you have any issues.

Thanks for the map recommendation. I'll give it a shot and let you know how it works out.

I finally got everything installed and was able to test ride the map M802-312. The bike seems to be running pretty good during acceleration but I do have popping on deceleration. I don't have a tach to indicate the RPM range where this happens but the popping occurs at or near 0 throttle and starts at anywhere from 50 mph in 5th gear and then at lower speeds as gearing drops (40-45 mph in 4th, 30-35 mph in 3rd, and so on). The popping typically continues from the speeds indicated above as slowing continues almost until I am stopped. As a side note, I did have some popping on deceleration prior to installing the Big Sucker and PC3 also but did have slip-ons installed without any fuel map modifications. Any ideas?

Try the attached map and see if it help with the popping. I also tweak the low speed timing to see if we can improve the throttle response. Let me know how it works.

I had to take a step back. After scratching my head a bit and contacting previous owner and then his original HD dealer I have found that I have had a Stage 1 ECM update (bought the bike used), so I grabbed map M802-313 from Dynojet website and installed (map is for the same configuration as M802-312 except included Stage 1 ECM). I still have basically the same popping issues (maybe even a bit worse). Sorry for the confusion, but I do appreciate the help thusfar.

Try this. Add 15's to the 0% column of the map from 2,000 rpm and higher. Then add 10's in the 2% column from 2,500 RPM and higher. Load that and see of the popping is reduced.
