How to use a SE pro Super Tuner for IDIOTS

[fltrdes]

"cooler running bike, and most effective power"

That takes a combination of accurate VEs, with a well established target AFR table AND timing   Many people throw fuel at the bike to cool it down, but slight changes to timing can impact EGTs tremendously.

Few posts above, Joe shared what he uses as a good target AFR map to use, AFTER the VEs are calibrated.  Other folks use a different approach and their map looks slightly different.

I have read the smart tune process varies results on the environment you record smart tune in, so if I were to do my own smart tune recording 'on the road' this process will have to wait till our Spring kicks in!
I have read that the optimum smart tune should be done around 75° or so. I would need to do this to accomplish correct VE calibration, right? Then induce Joe's target AFR and then retune? (considering Joe's hardware mix is similar to mine??).

[strokerjlk]

Once you change your Afr table ( as joe ) then you want to run it like that .
If you had a way of checking Afr other than smart tune ? This would be the time to use it .
You want to go back and verify what smart tune did was indeed what you actually have .
And if you really want to see if you have a good closed loop tune ? You would check the actual Afr after some time riding the bike. All close loop tunes are not the same . Some  deteriorate after a few miles . Garbage in garbage out .
If its setup right in closed loop, the adaptive values won't affect the "originally tuned map"
If you had a PV tuner you could shut off the adaptive learn.
But with sepst your stuck with living with them .
You should be able to find a decent medium with your bike .
Some bikes have no business running closed loop anywhere .
It is amazing how one spot in a map that doesn't sample correct , can effect the overall tune.


Your question about perfect temp to smart tune . I suppose 75 deg would be ok . Perhaps 100 deg would be better . Regardless the ECM dictates changes based on intake temp, barometric pressure , ambient temp , engine temp . Etc . Close loop or and open loop .So it really isn't necessary to wait for a certain ambient temp to tune . But I suppose 75 deg would be somewhat a middle ground .

I would say that a cooler temp would be better for road tuning because of the heat that you can encounter.  That afr table that I put up is a general run of the mill afr table that just about anyone can use if hardcore cams are used then it needs to change but for a 255 it will work fine.

One thing I like about the PV too is you can set two screens to read the O2 Integrator Values Front and Rear  as your riding after a tune...if they stay at or near 100% the AFV is not correcting anything any way

Thanks Joe, I will adjust my 205UH005.dt0 map to those settings and see how it runs.

My AFR map differs from yours slightly. I have an 75% column where yours shows 85% column.

[strokerjlk]

if you have decel pop  richen up, the 20 kpa column from 1700-4000 rpms

Jim said that to me in this thread way back, and IT Worked well in mine ....

My settings= 20 kpa over thru 60 kpa all set at 13.9 and down to 2250 on RPM (rectangle box set the same 13.9)

Thanks Jim...

Today was the first day I connected my SEPST to my bike and re-flashed my ECM. Upon connecting the tuner with the software initialized, I was required to download and update the software. After updating software and restarting, I was required to install software to the VCI. All good and the software populated with ECM P/N, Year, Family and Model. Since I have only ridden my bike a couple times since major engine warranty work and installation of the SE-255 cams, the only issue I have recognized at this point is some decel popping. I decided (after reading several posts about this issue) to richen up the fuel in the 'decel enleanment' area of the ECM.
I opened the custom file I modified (Original flash 205UH005-001.dt0) Don205UH005.dt0 and LOWERED the values in the 'Mult' (Multiplier?) column as you can see in the image below, saved the file as Don205UH005_DecelFuelMods3-17-14.dt0 and re-flashed the ECM selecting 'Enable Smart Tune Reflash' and 'Reset Adaptive Fuel'.
I am hoping to sneak up to an acceptable and positive fuel change to fix the decel popping without overkill....
I have not ridden the bike yet to check the decel popping 'cure'.

[joe_lyons]

Which decell pop are you having?  Poping when shifting or quick roll off or long drawn out poping?  Decell enleanment takes care of the short pops or when there is a delta change in throttle closing and if you have long drawn out poping you can add timing to the low map area and or adjust afr in that area also.

Decel popping occuring rolling off throttle (closed throttle) from 30, 40mph. Not so much downshifting.
I've read other posts (here or elsewhere) that timing changes we mostly ineffective. I'll know more on the next ride. I'm still in break in stages so thrashing around in a lot of hard pulls to push decel analysis may be a bit premature.
Question: When making these changes in the map and re flashing,  is it better to check the 'clear adaptive fuel' until I'm ready to do my smart tune runs?

Do you suggest any specific throttle applications to check decel popping?

Yes ...don't select smart tune unless you are collecting data .
You might want to try riding your bike without smart tune enabled , with the changes you made.
You might not have as much decel pop as you do with it enabled .

Decel Popping is address in the SEPST instructions (Version 7.004.0000) within the software SEPST Online Help section:

Deceleration Enleanment
"The Decel Enleanment Table, located in the Advanced Tuning, is a multiplier, which in part, tells the ECM how much fuel to remove during a throttle roll-out at a specific engine temperature. This is one of several tables and variables that make up the total Deceleration Enleanment fuel that is delivered to the engine. Other variables that affect the amount of fuel removed include: engine speed, map load, how fast the throttle is moved, and how much the throttle is moved.

Prior to a deceleration event, the engine is running in a steady state condition and is delivering a steady flow of fuel. When the throttle position is decreased, the engine eventually reaches a new steady state condition with a lower rate of fuel flow. The engine needs less fuel delivered during this change as the amount of fuel in the intake system is more than the engine needs for the new condition. On an EFI bike, this is called Deceleration Enleanment.

Decel exhaust popping is combustion occurring in the exhaust. Since combustion occurs over a narrow range of A/F ratios, popping can be cured by either richening or leaning the unburned mixture in the exhaust so it cannot combust.

Any changes made to the Decel Enleanment table increase or decrease the amount of fuel delivered while the Deceleration Enleanment mode is in effect.

Use this Tuning Table to increase or decrease the fuel removed during a Deceleration event so that it runs properly.
If exhaust smells of fuel on throttle roll-off – increase the Decel Enleanment cells to increase the amount of fuel Enleanment.
Use Data Items to identify what engine temperature the problem is located in."

This is from the Gospel. Not intended for any other purpose than to share what is IN the Moco instructions for those to read here, in case those with this device that may have missed it.

strokerjlk: Thanks for your suggestion. I think the selecting 'Smart Tune' would clear the VE tables and any other 'Adaptive' tables that have self adjusted entries during running.

It doesn't clear the ve tables . It sets the map up to be tuned .
Doing so will alter the map so that the software can collect data .
It's gonna be leaner with smart tune activated . Therefore your decel pop may not be as bad as you are experiencing with smart tune activated .
Set your smart tuned map up for the way you want to use it when your not collecting data . ( less closed loop) then flash that map without selecting smart tune , just select reset adaptive values . Then ride it to see if the decel pop is better .

[harpwrench]

On my bike the injectors shut off on full decel, then there's a little pup-pop near the end of coast down when they turn back on. Fixable or "they all do that"? CVO 009 cal.

OK, I will hook up SEPST, reset the Decel Enleanment table back to 'Original', save as 'Working', reflash ECM without selecting Smart Tune, then ride to check for changes....
Got it...

[strokerjlk]

You didn't make a very big change in your decel table . I would leave it as it is now . Just don't enable smart tune 
Harp
As long as the little pop isn't when you open the throttle back up slightly ? Then you should be able to pin point it and take it out .

[harpwrench]

Yeah it's if I don't open the throttle, almost have to do it on purpose actually, but working it out would be something to tinker with thanks.

This is a partial list of base maps that are in my SEPST selections. The one with the arrow is the base map that was selected to flash to my ECM for the closest match to my hardware set up: 2009 Road Glide, stock motor except with SE-255 cams and Arlen Ness ig Sucker air cleaner with stock oval cover. It also has SE lifters and Quick Install push rods.
This base map was modified for 96 cu in displacement.

In your opinion, is this the best base map to start with?
I want to start out on the right foot on this tuning setup before I start smart tuning process...

[hdmanillac]

I'd prefer the 044SBN004 cal for 1800CVO 2010-2012. Just modify Engine Displacement.

[strokerjlk]

Use the 2009 touring .009 sat cal
It's a lambda cal. Modify ci/ inj constants to fit your combo .

I appreciate your input, but could you please explain what the differences between my selected map and yours, for MY build?
I believe the O2 sensors are different and possibly the compression ratio as well?
What other basic map features of the 044SBN004 made you decide to use this on your '09?

[fltrdes]

Is your suggestion due because you can select fuel quality in the lambda settings? What makes this map stand out over and above the base map I chose?

It's a lambda cal . Ve table is map based instead of t/p
Easier to tune and smoother running . ( especially for a street tuner )

I don't use 044SBN004 on my bike because I use Dynojet Power Vision and this cal is for SE Pro Super Tuner.

I use the stock cal of a 1800CVO RK 13' saved with DPV. It's a 044 cal like 044SBN004. MAPE TOOTH IVO & IVC parameters are set for SE255 cams. You just have to change ci and do some smart tune sessions to get it set for your bike.

The 009 cal is also a good base cal.

With all due respect, brother, this thread is titled "How to use a SE pro Super Tuner for IDIOTS"
I am one of those 'IDIOTS' this thread refers too, so I expect (hope) responses here are by those with the intimate knowledge of the SEPST. I know nothing of the Powervision unit so trying to extrapolate its functions, maps, etc. and relate that to the SEPST is just confusing to me...
Thanks just the same...

It would be nice if I had a Dyno to run different maps with the controlled environment a Dyno offers and with a sniffer, but I don't. I would have a better understanding of what you mean by your post. Am I assuming that your abbreviation "t/p" is throttle position???
Since the thread is for idiots like myself, a better explanation of your statements would be helpful. Having had little experience with the SEPST I have no basis for comparison for "easier to tune and smoother running" from one map to another.

So far, I haven't been persuaded to change from my original flash 205UH005-001.dt0 which in the listing still sticks out with the correct year, cam selection, intake, and other parameters to set up for smart tune.
I know the fuel injectors from '09 (maybe earlier...) through '14 are the same, but the O2 sensors for '09 are different than '10 and later. I am thinking this is a significant factor for choosing the correct BASE map to start with. I also am considering that the different O2 sensors in '10 and later is the reason for lambda based settings in those base maps as well? This issue brings up a whole list of questions as well, like, what was the reason for the O2 sensor change by Harley?
