The analogy using Windows is fair enough. I can't stand that crap. I much prefer a good unix, which is far, far easier to use if you want to do nuts-and-bolts type of things (and not to mention vastly more secure). That's the reason why between the TMAT and the DTT I'd lean more toward the latter. It appears to be very much more "unix-like".

 

Hey Sleepyjim, i know how your feeling, im lost in this whole deal, and i'm concidering the t-max as well, or the DTT, not sure yet

 

Just for those who may be feeling a little TMAX gun shy...I've got an '07 RKC with Thundermax autotune, zipper's stage 1 A/F, and V&H bigshot Duals. Running base map for Rinehart true duals (forget the #) All I can say is it runs like I hoped it would from the factory. Absolutely no tweaks, no pinging and no heat issues. I've run from sea level to over 6000ft on a hot day with no probs and almost 2000 miles on the set up. ABSOLUTELY satisfied and I paid full pop from Zipper's.... No worries, mate! Plug and PLAY!

 

I tried to duplicate your methodand I think you have a typo at the 24" point. I got:

?? in-Hg = 0% Throttle = 11 degrees
16 in-Hg = 2% Throttle = 12.54 degrees
18 in-Hg = 5% Throttle = 14.85 degrees
20 in-Hg = 10% Throttle = 18.7 degrees
22 in-Hg = 20% Throttle = 26.4 degrees
24 in-Hg = 40% Throttle = 41.8 degrees
26 in-Hg = 60% Throttle = 57.2 degrees
28 in-Hg = 80% Throttle = 72.6 degrees
30 in-Hg = 100% Throttle = 88 degrees

I'm still trying to decide if I want to spent the extra $$$ to do the TMax upgrade on my M-M 2000 Road King. The PCII doesn't help at all with the cold stumbles.

 

The table in https://www.hdforums.com/m_2080382/m...tm.htm#2088091 is correct.

 

Can anyone tell me what the Accel Fuel setting is for and if it may help me out. I have the TMAX on a 2007 FLTRI, K&N and SE slip-ons. I had some pinging when bike is hot, backed the timing down slightly in those ranges. I can still get a little ping when bike is warm if I blip the throttle in neutral. I think I read that increasing the Accel fuel may take care of this. Is this true? I am tired on the ping.

 

I know this is probably a dead tread, just searching for clues along the same path.
I am 2003 Roadking Po Po bike
510G Andrews cam
V&h monster slip ons
I was given a set of cylinders and pistons off a 2007 Cop Bike (103)
after attempting to install, realized what the 103 in comapairson to the 88 required. Cylinders were taller and piston shape in the inside were different. After having the pistons and the base of the cylinders machined down to match "oem" specs, went along with build.
At the time I had the first gen Tmax ECM. I wanted more tuning options, so opted for the 2nd gen module.
My problems are.....
Bike idles great, accelerates great. I'm very happy, BUT at steady throttle between 2000-3000 rpms bike sounds/runs poor. It feels like the rear cylinder is out of time. rear cylinder plug fouls bad. Mileage at best is at 20 mpg. I just bought the newer model (no O2) in hopes of better map options.
I'd like to think I've tried all maps in attempt to rid myself of the steady throttle misfire, but have failed.
Right now I have the map for 103 ci, 203 SE cam, and SE mufflers, 01-05 Heads with OEM injectors.
What is the process of advancing the rear cylinder timing?
As a side note, all, I mean all sensors have been replaced. I also rereplaced intake seals, just to make sure all is well.
Anyone still reading this thread.... Open for suggestions, thanks

 

Well said, and I agree. TMAX. Timing is often in the dirt.

 

Hopefully they corrected it sometime in the last 12 years. Great day for thread resurrections.

 

I have Tmax with Fatcats on a 05 RK thats been upgraded to a Screaming Eagle 103. It also has S&S gear cams but I do not know which ones..What I have found is mileage is at about 40mpg running with my wife following. I do note that its pretty particular about fuel. Just got back from a 550 mile trip where we got gas about every 100-120 miles since my wife has a sporty 3.3 gallon tank and while running 91 nonox, Filling up at the only available stations. After 2 of the fillups I experienced ocassional backfire at startup, either out exhaust or throttle body. Especially after slower traffic, 30-40 mph instead of highway speed right into a station. Now this bike is manageable in town if I keep RPM's up not ******* it, but it seems if I could give it a regular diet of 93 it would be better. Long story short I understand why the ignition is retarded a smidge, I feel no dead spots as it pulls very hard.
