So I finally got ECM Spy to work. The cable I had been given with my bike had been put together wrong. First I found out that one of the pins had been pushed in and not connecting. Then on top of that when I went to connect it, it shut the PC down immediately. Turns out whoever built the cable put the yellow wire in a spot that would to me appear to be 12v power out of the ECU and caused my pc to shut down immediately.

I fixed the cable and finally got ECM Spy to connect and all is good. I backed up my eeprom data and thought I was on my way. My question is this:

I got the race ecm data from purpony and tried to load it. I loaded a .msq file that I believe is the entire race tune, but there is also a .txt file named race tune as well. What I did notice is that when you save anything it backs up a .txt file as well. Also, after I loaded the one .msq file I had I realized that my backups of the stock tune are a .epr?

So I guess my questions are this:
is the race tune fueling maps only, or ignition as well?

And, how in the world would you load any of the text files?

My bike runs at least at the moment, but to be perfectly honest I am not sure exactly what I loaded...

Ok, so I have made some progress so far. I have confirmed that the ecu is showing firmware version BUEJA120 which from my understanding is the race software?

I performed a TPS reset and the bike is running a lot better now also. My idle is not hanging at all. I am getting a cough and pop out of the intake though and the bike still stutters when you get on it. I have a V&H exhaust and a semi home made forcewinder style intake with the air temp sensor inside of the intake tube.

Any suggestions are very welcome, and I think I am at least heading in the right direction...

Coughing cumfort :- As the automated ECM programme moves between Closed loop and Open loop to the learned AFV it will cough precisely when the learned AFV correction is applied to the fuel mixture.
The AFV will be learned when the bike is operated at engine speeds between 2500 and 3500 rpm at road speeds in the 40 to 60 mph range under a steady light load (smoothe throttle control, no steep up or down grades, decelerating or accelerating) for 2 to 3 minutes.

Anticipate the cough accelerating above 3500 rpm .

I wish I could help you, I just ended up buying a Race ECM and use ECMSpy for TPS/AFV reset and diagnostics.
I wrote to the fellow on eBay I bought the cable and race software disc from twice and never got a response.

When I had the bike running it was showing AFV at 149 and the needle looked pegged to the right...do I need to reset the AFV and go for a long ride on a strait road? The coughing is a pretty good stutter and then it finally takes off.

So far the bike is running so much better at low speeds like in parking lots, etc. It feels stronger as well; I assume because it was running lean before.

Reset the TPS, reset AFV (it should be at 100 after the reset), go for a 10 mile drone on the highway and recheck the AFV as it should have changed.

Try this. Hook up to EcmSpy.

EcmSpy/go to Diagnostics, choose Reset the AFV to 100%.

EcmSpy/go to ECM Runtime. Now with engine idling watch cold start enrichment box until auto choke is not influencing any more,5 minutes approx. You should warm the engine correctly every time you ride.
Set TPS with engine at running temp if you havn't done this already.

Time to go for a closed loop ride on the highway.
No antics just steady all the way home.
When you get back check AFV.

Would a TPS reset effect AFV at all?

What I essentially did was load the race software, let the bike warm up, and went for a ride. I noticed that the RPM's were hanging by the end of my apartment complexes street. I kept going for a ride anyways because sometimes it just goes away. I went for a 15-20 minute ride at around 2,500-3,000 rpm all pretty steady since I was reading about having the AFV learn.

When I got back I did a TPS reset all while the bike was warm, and went for another quick ride. Same issues except that the throttle was smoother and the rpm's didn't hang at all.

Did you check AFV when you got back?
Is it still adding heaps of fuel?

What was it running like before you loaded race software?

AFV represents actual air/fuel mix ratio. TPS is for timing that fuel mix ratio into the cumbustion chamber.

The bike was running ok before, not great though. It would cough a lot at lower rpm's and just didn't really feel very smooth. It actually feels better now riding around in parking lots, etc.

I did have a thought though. Does changing the mapping change what the AFV level would have been? My thought is this: I installed a new intake and it already had the v&h exhaust so it was probably running really lean. Maybe the AFV was trying to compensate for the lean scenario and it just stayed that way?

No maybe about it adding fuel to compensate for the lean scenario.
With AFV at 149% it's adding 49% more fuel.

Q.Does changing the mapping change the AFV. A. If you change to a lesser fuel value it will add fuel.

I have a V&H exhaust and a semi home made forcewinder style intake ????
This sounds sus, If you can't buy replicate the correct air filter for V&H.

I have a metal intake elbow meant for a carbed bike that I drilled a hole for the intake air temp sensor. This is not something unique or unheard of, and as far as I can tell I have no leaks. Either way, it was not doing this before switching to the race software so this is a tuning issue.

Good luck.

Ok, so i reset the AFV to 100% and went for about a 10 mile ride down a pretty strait 2 lane road at about 3100 rpm the whole way. The bike is running awesome now. Idle is great, it is so much more pleasant to ride. No more bucking and boggin off the line or in parking lots. The power feels a ton enter now as well.

I checked the AFV when I got back and it is reading 105. Does that fall within the normal range? It is fairly cool out tonight for southwest Florida if that makes a difference.

Thanks to everyone for your help and suggestions!

Nothing wrong at 105,my X1 with race ecm was always 103-108 and the S3 stock ecm 110-120, both ran great.

Sweet.
EcmSpy/Trouble Codes if there are any and clear the trouble codes.
Keep an eye on the trouble codes.

So far no trouble codes. I lo e the fact that on e you learn what ecm spy can do you really have a lot of diagnostic power.

thanks again for everyone help, as always it is greatly appreciated.
