Hi Ljubo,
After starting several times over 2 summers never did I have a voltage drop far enough to have to re initialize. The only time I had to do that was when my battery died which was kind of my fault.
13:1, do you mean compression ratio? Wow, thats pretty high, or are you meaning something else? I had 10:1 on the bike Tmax was on.
I dont mean compression. So high is acceptable only if are you running on methanol . I am asking about Air / Fuel Ratio (1 part of gasoline mixed with 13 parts of air). You can check with PC Windows
start TMax SMLIV
-configure
- closed Loop Module Settings
- Air Fuel Ratio Override (MAP)
- click on AFR (Map) button
and You see AFR Override with 13.00 as default.
There you can change the fuel ratio, which is as baseline for close loop operation with wide band sensors.
You are obviously running with default 13.0 : 1. A simple question is, is yours bike milege the same as before installing TMax ?
with TMax installed what do You get on display if you follow the procedure descripted in Thread "Diagnostic codes... in first post in Adobe document Diagnostic Trouble Codes (DTC’s) through 2008. If someone has time
please check, especialiy I am interested in step 8). The Pn and code is code of software in ECM, TSSM and speedo respectively. Under P I get Pn 32919-04A
foloving the procedure - step 8.
That was dumb of me. The map I was using had various afr for different throttle positions, ranging from 12.5 to 13.7. I leaned the afr from 60 to 80 mph, (do you prefer kph?) to 14.2 for economy, however after doing heads, cams and Tmax I never regained the economy I had with just stage 1 but the engine ran very well, it was worth the tradeoff.
Hi Tommy,
Did you ever hear about problem of voltage drop when starting? This should reset the TMax and you have to re initialize the unit again and again. I think that this is not true. I hope.
Are you running 13:1 or something else. With 13:1 does the engine need more gasoline or is the change minor?
Regards, Ljubo
I've never heard of this. I've had two tmats and never had this problem. I actually have a good used one for sale.
Hey there Lj, I don't think you have to worry too much about cam selection for the base map, when my Tmax was first installed the shop put the wrong base map in and it still ran well. Two different cam sets with the correct base map and all was well. I hear people are liking a Woods 6 cam, good to begin with and accomodates future upgrades.
Stay warm Ljubo.

i have the woods 6 but i dont have the o2 sensors, what year is your bike and engine size, how do your maps print, im working on a map and it getting better but it taking time.
I was reading the thundermax threads to gain insights to their inner workings base on the comments and issue spoken of, this perhaps could help me bring my own issues to a conclusion and at the same time acclimate me to what is a new product to me , thundermax. one can print a pciii usb map and mail it or email it . a printed mailed map could be transfered to the zero map and ureka you would have a map.
The power commander usbiii has the web site were they post maps of bike with different exhausts and down loads . there are even a few with cam changes but they are only 203 & 204 cams that are listed. they also have some for 95 '' bores , and some for bikes that have stock maps.
Fuel Motto says they have maps for the pciii usb but they will only share with a reciept from them , thease are maps for open loop bikes , pertaining to pciii usb.
we have no 02 sensors on 05 bikes, the cycle needs to be told what to do and when.
i just put in an w6 woods cam and changed to belts and gears instead of chains and shoes.(my hand was badly broken so thanks to my brother dave for supplying the muscle were needed) my pinion run out was.003 , that was in the upper range of the harley shop book,( with in specs) but S & S would not committ to me that i could be sucessful with that amount of pinion runout even though their instructions said .003 was exceptable but the max.
so now i am trying to find someone with a solid pciii usb map that can be sent over the email so i have a solid base to start with. ( gear cams will work- yes- , gear cams will work -no , ok . but gear cams will work maybe - doesnt fly)
The current map , being used , is what i believe to be close but i really dont like to do things half and half. i usually talk to shops before i give them business, but its hard find shops that love bikes anymore, so when i talk to them i get " im experienced and own 6 harleys myself ". well then whats your favorite lifter and why ? i get answers like oh i dont know.
so i would use a dyno , if i could find one within 15 miles or so and , if i can afford it, and be happy to pay them a good wage , but i dont want to subject my cycle to hours of standing dry runs to get something close, i can get something close.
Sorry to be so long winded, its just frustration, there are good shops out there, i guess you just have to look for them and good parts suppliers as well, you just have to find them.
when i was a kid you took your bike in paid the guy and the thing ran like a champ , seldom did you have to return to get it right. i found the wrench and would sweeten the thing with extra money or movie tickets for the upcoming favorite show for him and his gal ( the new james bond movie- live and let die) or some Christmas spirits for the holidays, but i dont give out booze anymore. These days business has change and so i do every thing i can myself. I guess i need to grow up to the reality of life. PLus after doing some things on the cycle, to me , wrenching takes some attention.
I need a map for an open loop 05 tc88 softail for a w6 woods cam.
i hope something i said has anyting to do with your reply. thanks
Hi Harold, your frustration is quite valid. I don't know much at all about the Power Commander and their maps, what I did with my Tmax was load a fairly close base map and then tweak the actual map myself. It seems good info is hard to come by for pc, a buddy was having the same issues as you and went to PC 5 and auto tune.
