Because I am unable to tune new 2012 Dyna with TTS as yet, I have bought a SESPT to tune it.

I had already completed a TTS calibration for my build thru Vtuning and then Dynotuning to complete it. This cal I was extremely happy with, and since I am building the new bike to exactly the same specs, I want to use this same cal again.

It was easy to copy and paste all the tables from the TTS cal over to a SESPT cal. I started with the closest cal I could find on the SESPT which was basically the same as the TTS  PS176(mt7). My TTS cal was based on the DPS176(mt8) which is not that much different.

The only thing different was a few cells in the AFR table. The SESPT has an 85kpa column, which the TTS cal I used didn't, so I was able to run the afrs in this column in closed loop up to 1500rpm as well. Also a 27kpa column that I can run in closed loop to 4000rpm.

The SESPT does not allow you to change the following tables (well as far as I can see so far anyway).............

PE air-fuel ratio

PE Spark

Spark Temp Correction

Closed Throttle Spark

Adaptive Knock Retard

IAC Crank to Run

EGRs and

Minimum TPS for Baro Correction

No Cam Selector either.

Except for the Cam Selector, none of the others I have changed anyway and the average joe probably wouldn't play with these.

Not sure what difference the lack of cam selection will play........but hopefully not too much!

Now all I have to do is fit the heads and cams, then flash this tune to the ECM and see how it goes...............stay tuned!

As you know before the TTS cam analyzer we would pick the SE cam with the closest specs to our aftermarket and Vtune from there with no melt-downs that I read about. This is a great thread for JD and the other guys with the SEPST to follow if they decide to run the aftermarket cams.
Good luck and thanks for starting this post.

Thinking it's a fucking shame we lost Scotty on this forum because he would know all the answers with your map. He was running both the TTS and the SEPST in his bike.

question is a 255 cam a 255 cam no matter who makes it ?

 Fitted up heads, cams and Baisley spring today. Went to load new cal with pro tuner and realised that the 2012 models won't take a 176 file, only accept 357 files.

No probs.........picked a 357 file and copied and pasted my 176 mt8 tables over to it. Had to play around with AFRs a bit as was limited even more to what can run in closed loop. Also noted that CLBs are not accessible in 357 cals. I guess if I can't change them then no point in worrying about it!

All good so far, took it for a short ride and seems to be running as the old bike did...............REAL FKN GOOD!!!

Plan to clock some kays up over the weekend so will get a better idea on the result.

Waitin for ya report Burto.

 

 

 

 

 Clocked up about 400kms over weekend. Bike is running a little lean, had some pinging when loading up at lower revs, also could tell by the sharp exhaust note.

Don't know what the CLBs are set at in the 357 cals, but if they are anything like the 176 cals then they are pretty low. I used to run mine at 720 across the board. Not sure if this is what is causing the leaness or if it is even in closed loop when the pinging occurs.

Might have to do some data runs to check.

Burto.

 

 

 Did a short data run today, concentrating on the areas that I hear pinging..........with this tuner you gotta put it in "smart tune" mode to record anything. A bit like recording a vtune with TTS, but you don't get the histograph.

You download the data to your PC when done and then you can either see the results of the smart tune in the VE tables (suggested values you have the option of changing to) or you can view the Data Items in a list and on a graph a bit like scan data.

I left knock retard enabled so I could see where it was pulling timing and found a couple of spots in the 2500-3000rpm range at a couple of  throttle positions. It was only pulling up to 1deg and mostly on the rear pot. After checking MAP values I determined that it was mainly occuring in the closed loop areas so instead of adjusting AFRs, I richened up these areas in each VE table.......more so in the rear as that was the main culprit. 

Took it for a short run and couldn't find any engine knock but will recheck on a hotter day on my usual route where I always noted pinging. If I need to I will readjust as neccessary.

All pretty straight foward and I must say that the user manual that comes with the SESPT is quite good, explained in fairly simple to understand terms.........probably better suited to the novice like me!...........I often found the TTS user manual a bit of a chore with maybe a bit too much info for me to wrap my few remaining brain cells around!!

Mate what advance are you running? I know that it is varied across the board but the TTS starts at around 20 deg and goes up from there. Did you add any extra to your spark tables before or stayed with what you had before? And yeah I agree with you how the TTS is written. Written by a boffin in his language and makes assumptions that everyone understands what he is on about.

Thanks mate....Mate keep us posted with what you do. I don't use the SEPST so I don't know anything about it but I think the same principles apply for that and the TTS....

It could be a trade secret Hilly or maybe there waiting to learn a few new tricks from Burto.

BE careful. The SESPT when you set it up to use smart tune changes your calibration without you knowing it. To see the changes you can see, program the bike with smart tune enabled from your starting calibration. Once that is done open the calibration but use the one stored in the interface. Take a look at your spark tables and you will find they are changed from what you started with by about 4 degrees. It also changes the fuel mixture to what it wants versus what you set it to be. So your not really running what you think you are in that mode.

 Thanks for the heads up Steve!

I checked and you are right...........spark down by 4 degrees and more in some areas, less in others.

This probably explains why the knock retard was only pulling up to 1 deg............I expected to see spark retard of 4 deg or more where I experienced pinging. 

I checked the VE tables and nothing changed there.

This is only happening while smart tuning, and as I only made my own changes to my map before reflashing bike, does not affect it. Not sure if it will change the spark tables in your map after you  "update" using the smart tune feature. Will have to check that out!

Still have a brand new TTS interface sitting there waiting for your 2012 updates!!

Thanks,

Burto.

Just understand that there is more changes being made that you cannot see, only when you enable the smart tune. So anytime you check that box it will make all the changes regaurdless of what you changed. Best to just be careful with it.
