IN the process of building my 09 UC
Build specs 09 103, SE FT pistons,TW6-6 Cams, Big boys Streetport heads, HPI 54MM reworked stock TBW TB, Cold cranking 10.3:1. cold corrected 9.5:1, Altitude correct CCP 194.
Been told that I could start with 20082009 Touring 1690 HO pistons, 258 cam, heads TW205-000
Does anyone have a TTS map built with similiar build that they would be willing to share? I would think by starting with a base that has been dialed in would be a better starting point.
I have a pretty similar setup to yours with my 07, when I tried the 258 map for that year it ran badly, if the tts has something for a 255 camset it will be closer for starters.
Were you using a TTS map or a old SERT map when you had trouble?
Not sure if this question was for me but I was using 4 7 7 SERT map MT6 when I tried the 258 map, not saying it was bad, just stating that the 255 was a closer start for my particular build that is very similar to the original posters, fwiw, neither map would even come close to being acceptable for everyday riding, just one was a bit better than the other.
Steve- care to enlighten me on what map you would reccommend I start with?
What are the cam specs for the TW-6 cam?
TW205-000
UH205-000
TQ205-000
Any of these map would get you going but not knowing your cam specs I cannot say for sure. Bottomline is that they will all work with a little V-tuning done to them.

The SERT maps are from HD and the .mt7 files are from TTS so that's why I want to know. They are not the same so we need to keep people from assuming they are.

As stated previously-It was recommended that I begin with TW205-000, Just wanted to make sure that this map is a good base to start with. I am by far an expert. I know that you mentioned start with a map that is close to your cam specs. These two don't look very close to me. What do I know??? Just trying to learn and understand.
I have a very similar setup on my obsolete 2008. I used the UH205 as a starting point and did the Vtune which made it a well running bike. The Vtune process will take care of the significant differences between the two cam. Don't agonize about this, it is just a motorsickle.
Finding the best timig curve without experience and a dyno is the challenge.

I would start with the UH205-000 or the TQ205-000. The cam you have is between those 2 base calibrations. I would not use the TW205-000 as that is for a much larger camshaft.
