Ouch and the timing topic is interesting but as I have posted my opinion before concerning the upswing of a timing curve... timing should be adjusted when on a dyno so you can closely watch the power bands and see how your adjustments react to them being up or down and how it effects everything else such as smoothness and rideability. Once done the VE's can be finalized as timing will effect these tables. Again, just my opinion, advancing your timing until it knocks is not the correct procedure as this may rob your motor of not only power but efficiency as well.

Steve has a procedure to follow but I think this may only be a suggestion and it is also said once knock is found you must reduce the cell down 2*. He has told me that there was no less than 16 hours spent and three different types of fuel used on his timing tables and I, for one, am not smart enough to know all the characteristics for properly tuning a bike. However, I do consider myself as a good pupil that likes to question some of the TTS procedures so that I may learn more but never to question his ability or the TTS as a product.

Sorry I got a bit long winded.

 

Way cool!

Now... when you flash your last calibration it will take about three tanks of gas before your ECM sets it's adaptive learning and tweaks the tune itself. Your MPG and smoothness will improve and improve.

Enjoy my new friend.

 

Mr Wizard

Can you reccommend a starting map for The andrews 48H cam. My setup would be for 08 96 CI (stock compression),adjustable pushrods, se slipon mufflers. The specs for this cam are as follows

Andrew 48H cam specs

13 - Intake Open
29 - Intake Close
43 - Exhaust Open
15 - Exhaust Close
222 - Intake Duration
238 - Exhaust Duration
28 - Overlap
98 - Intake Lobe Center
104- Exhaust Lobe Center
101 - Lobe Separation Angle
0.548 - Intake Lift
0.548 - Exhaust Lift
0.153 - Intake Lift TDC
0.163 - Exhaust Lift TDC

Thanks in advance

 

what bike? Touring, Softail, Dyna?

 

08 street glide

 

TA205-002 will be fine to start, you could use the TD205-002 also. Your cam profile will work fine with either calibration.

There are combinations that run out of room on the VE tables due to ported heads, or just all around better breathing. There are 2 ways you can adjust for this condition, one is increase the CI and the other is tell it the injector is smaller either one will pulse them longer.

 

Good explanation. Timing can be a daunting thing to mess with when you have no way of measuring progress or lack of. There are times where a couple degrees less timing will show an increase in either HP or Torque, on the street its a tough thing to measure.

 

This is the procedure I have been following from the TTS manual.

 

Just got my TTS, looks like the SEST
