Screaming Eagle Race Tuner

The SE 120 is one heck of a motor
I'd call liberty HD and see what they would sell one for if I was lookin

Well this is a sert thred and the fact that some thinks the he can tune it with out a dyno or a wide band o2 sensor wich is what the dyno does under load. Is inpossible . You want to start with the canned map but there is no way you know what the ve table is that your motor will need . The propper way to tune a motor with a sert . Is to set the air fuel table to 13.2 or lower. And do a pull to see that your ijectors will get you there threw the rpm range and throttle position that you requested if you can do that with out a dyno in a 6 hour period for both cylinders you are the man . You will need to do it for all positions of throttle and all rpm ranges to get a perfect tune . For both cylinders . To verify that you have the ve tables correct you need a wide band air fuel sensor in the exhaust.

What is miss understood of the t max is that the maps they give you are canned they are close but far from canned. They assume the fuel flow . Most if not all the maps have a set air fuel value written you can change that value from what they give you . Lets say wide open is set to 13.2 but you want the value to be 12.5 at wide open,confirms what you requested and your done write the map and ride again what you request is what you get now . You can drop just about any map from there list install it and ride it in stop and go traffic and it will learn the air fuel ratio you requested . The timing maps are very simple to write i mapped both systems for my self and also tried a revolution performance set up . The sert can get the job done revolution performance set up was ok but no timing control. T max does what it says it does . Will tune your bike to perfection you have to give it the input you want and it will do it and you can confirm it if you have a 124 ci motor and you want it tuned with a wild cam it can do it . If you have a wild cam with a delphi speed density system and its not a harley cam part number good luck on a canned map cause you wont get it done with out shifting injector size or ci displacement to trick the ecm to give you the fuel you need

In the 12's is running rich, from 13 to 14 is leaning it out some to git better furl milage.
Run it around 12.5 at idle and up to 13's above that.
All bikes are different.
Wish I knew a tuner around here that had a good dyno and knew the Tm and could Dyno my bike. It would learn a lot faster.

If your still running a converter on late model bike 13.5 13.8 is what the conveter will take . What you are trying to acomplsh is to confirm it can get you there. When your done you will re install the factory air fuel ratio for that map. Once your done shifting the ve tables to get you to 13.2. That you requested. Its alot of work with out a dyno and very hard to do with out smart tune software. It took me 35 hours . To get it perfect with the sert both cylinders.

You have to realize that those maps at the dealer the dyno operator keeps in his computer and many of the combos sold at the dealer have been run at the dyno , so why not pay the dyno operator 250 bucks to download the map confirm the air fuel ratio and tweek it here and there , and if it dont run right take it back. They do 4 full pulls and they have it if you have bolt on crap with there heads cam and exhaust they ran it already

Got a fuelmoto stainless header pipe, it has both size bung holes.

Cb i run my deuce idle after warm up 13.8 . Hiway 1/4 to 35% 13.8 14.1 any thing above that 13.0 12.5 and i have no problem it runs awesome t max was what i needed the timing map was very good lowered it in 3 places i used timing over rpm to play with it thorttle position was way to much work with out the dyno

Cb did you get your t max from jaime

My fuel milage just ain't what it should be.
I don't play with timin, don't know enough about it.
Know if you don't know what yer doing with timin you can burn yer motor up.
With the Fuelmoto stainless header pipe, and both size bungs and sensors in both you can pull the fuse for the ecm and take one out and put the other in in minutes. Say you needed to take it to the dealer for work.


 Jackpot 2/1/2 Headpipes

No, I got it from a Indy shop I worked at for a year. I set them up as a TM dealer.

I git about 35-38 mpg running 70 to 80 mph.
Try to not run faster, But it happens .
Do a lot of two up riding.

Cb very smart to do it that way. As far as the air fuel ratio set at 13.2 guys its only set that way to adjust the ve tables . Once the ve tables are set you go back and reset them all back to the factory air fuel table for the throttle position and kpa . When you go in to the sert menu in advanced mode you will se the actual values in air fuel ratio a throttle position . For that map thats what you will know reset them for and leve the ve tables were you set them at to get you to 13.2

CB Did you try the smart link program and send tmax your map and see if they can help you with it

Gee wiz got to get up early it 10 45 got to get up at 5. Talk to you guys later
