Which funny if you see the post above mine he says what the values are (Thanks saves me a ton of typing ) Anyway, I linked to the Tmax and made all the changes to the map with the AFR curve to improve mileage to around 40+ if not 45+ MPG...

Well in the last 3 full tanks I have run through I am only getting 30 MPG....

I re-initialized the ECM after making the mods and all, bike runs great and strong power out the wazoo...

My question is do I need to WRITE the files back to the ECM? It was/is my understanding if you are linked to the TMax and make changes they are live active changes...After the first tank of gas and the 30 MPG I did kind of verify that the changes had been input properly by "READING " only and checking each RPM range to see that the modified values were indeed there.

Can someone help with why my maps are set up for 40+ MPG and I am getting only 30MPG??? I will glady send them to you to view....

Don't get me wrong I like the power and all but I would like to get more than 150 miles out of 5 gallons of gas @ $3.15 a gallon

look at the difference between yours and renegades builds! also, even if yalls builds were close, your pipes would keep the mix wanting to go rich from reversion.

I know that Zippers says to set the Target AFR at 13.0

However, what have you set yours at for performance and mileage (crusing) at?

Thanks

I'm running 14.1 in the cruise range and 13.1 everywhere else. I have it smoothing from one to the other.

Also had to advance the ignition timing considerably, especially in the cruise range. Actually had to retard it a bit outside the cruise range to get rid of pinging under a load.

Do yourself a favor and go to an automotive repair shop and see if you can have an old O2 sensor they are throwing away. You can use it as a dummy to hold up to your pipes (BEFORE you remove the pipes) and figure out where to put your sensor. While holding it on your pipe, you can draw around it with a Sharpie to mark the spot. Be sure to allow room for the wiring coming out of the sensor. That's what I did for both the front and rear O2 sensors.

Okay Joe, there's your first mistake LOL....I don't even remember what I sent or where I was on build!

I'm getting between 36 to 40 depending if I'm cruising or getting on it...which I do a lot. I might go a little leaner, but I do love roll-ons at 80 mph and leave others in the dust! Much more priceless to me than gas mileage right now.

Are you messing with the enrichment circuit..which I use to do, or just the AFR tables?

Now I modify my idle to 13.4 through the AFR curves and then ramp up to 13.8 for cruise.

It works on my build, but by throttle position is very (and I mean very narrow) with the HPI 51 throttle body, so if you are using one of my newer maps, you might be in the 12.0 roll-on area.

As Claydbal points out, there is a little difference in our builds!

Send the file back to me at nc-renegade@hotmail.com and let me take a look at them and will modify what I think you should be running.

Regards,
NC

please do that so renegade can straighten you out!!! also worth mentioning is with his build------his tps is at a different position than yours at any given speed(less)!

Youo've got mail

I just used the basic curve of the AFR compared to your map...I started @ 2048 and modified the map up to 30XX (don't remember the value) RPM's.

I did the exact same thing.... got a 45 degree bung on the front, it's mounts vertical right behind the frame brace just like the stocker on '07s. On the rear ya gotta be more creative due to the V&H fuller heat shields and the tranny-top vent on '07s+. I mounted *just* aft of the curve outta the head and facing forward as close the the front lip of the heat shield as it would go. The bung points toward the gap betweeen the rear jug and tranny cover and the cable snakes back and under the starter. Pretty well concealed from the right side and looks like it belongs there from the left. YMMV.

went and got a old o2 sensor yesterday from a auto shop will check out placement today. TL MITCHEL has posted where he placed his i will check it out and see if i can follow his instructions. sounds like he put his in a real tight spot on the rear pipe. more ?s to follow thanks for all the replys.

As ya may have noticed, I don't know vertical from horizontal on the front header. It was placed *horizontally* same place as the OEM.

As for a tight spot in the rear, it was the only spot. Due to the increased coverage of the V&H heat shields combined with the tranny breather on the '07s I didn't see anywhere else it'd go considering the TM sensor is longer than the stocker and still stay within the recommended 4 - 6 inches from the head. Plus it's pretty-much hidden.

I used the sensor to mark placement then took the pipes to a muffler shop to burn the holes and weld the bungs. Good idea to take the rear shield along so they can see what you're placement is relative to the shield cause once they start burning the hole the placement marks disappear in a hurry. Guy got mine just a tad off and had to fill part of the hole and reburn.

Although I purchased bungs from Zippers I ended up using H-D bungs picked up from a friend in Milwaukee. Used the angled bung on the front, same as OEM. On the rear I used a straight bung which is what gave me the placement I wanted. The Zippers' bung on the rear probably woulda given more room for error as it fits flusher. On the front I used the angled bung cuz I wanted the same fitment as OEM... the Zippers' would have resulted in an angled sensor instead of a horizontal one that hides behind the frame brace on the downtubes.

I searched this thread for *98" and GMR* but no hits.......

Is anyone running a T-Max AutoTune with the 98" engine?

If so, what map are you running, as there are no 98" selections in the TMAT folder? On edit: I realize that the map you are running will be dependent on other factors as well, and as everyone has different combinations they will be using different maps; so I guess the question should be, how did you choose which map to use?

Did you install TMAT before the upgrade or after?

Thanks for all information, John

I pick maps the way the manual states...in the order of importance.

1. Throttle body / injector size and style
2. Engine displacement, I would be tempted to use a 95" because of the stroke. (Manual say's a correct match to stroke is far more important than an exact displacement match)
3. Exhaust System Design

I'll look at my map number later, but NC said it all. I use 95 maps because of the stroke. The 3 cc's chamber difference will be adjusted for in the autotune fuel flow corrections. Just pick the 95 map that most closely matches your config.

Look at my build The MAP is very good..Some tweeking could be done but I am just enjoying the ride...

Thanks for the advice guys, pretty much what I figured out. I am getting the same Map 254 for both 88" and 95", so I will plug that one in, I am still at 88" for now. Why are there no 96" showing I wonder?
OK, back to the install.............by the way, there is 1 unit on ebay with starting bid of $600 for anyone considering = search for 270194797981
