| | Posted : 17 Sep 2023 - 23:43 Post title : 2010 Thunderbird backfiring and popping | | | I recently got my hands on a used 2010 Thunderbird. Got it from a local dealership so no history on the bike. Has 30k miles on it. I've had issues with excessive popping and backfiring in the air box occasionally and dieing. I've searched through the threads and tried a few things.
Checked map tubes. All intact. Changed Air box sensor, afterwords reset engine adaptions with Tuneecu. Ran great for about 3 days and then started slowly getting bad again.
Changed plugs, it had DPR7EA-9s in it, I went back with DPR6EA-9s not sure how much difference there is.
Start researching more. Realized that the CATs where deleted, and it has the long TORs A9600302.
Then I started thinking it was map tune. Had map 20306. I tried 20306Map_with_PC5_TRIM_6400rpm_220_kph.hex (Silverfish Tune) ran terrible. Backfired and died 3 times in a 4 mile round trip around my house. Tried TarkMalbot_PC_tune.hex. Dies on idle and pops worse, but no backfiring. I know that one was for the 1700, but some folks said it worked good for the 1600 so I gave it a shot.
I did notice that on Tuneecu. The Manifold Absolute Pressure Sensor 1 voltage wasn't reading any volts. pressure sensor 2 reads 2.2 volts.
Also it is an SAI bike, and has an KN filter in factory air box.
Any suggestions where to go next?

Is the SAI system still connected? If not is the SAI box in TuneEcu ticked or not? Swap the MAP sensors around and see if the fault follows, if so you have a faulty sensor. Is the popping and backfiring all in the airbox?
Sort these out first then run the TORS tune for a 1600 and see what it does.

On the SAI. It's all still there. Not sure if it is functional. I ran a test on tuneecu and it didn't say bad... I'll spend some more time looking into it. Not sure if the oxygen sensors are still there. I'll find an diagram and confirm one way or another.
Not sure if it is ticked in Tuneecu, I will confirm. Still new to tuneecu
Asfar is popping and backfiring, it's mostly from the pipes, with the occasional backfire through the airbox. Went as long as 2 weeks (riding daily) without an backfire in the airbox. Then I've had it happen 3 days in a row.
20306 is the TORs tune correct?
Thanks again for the reply!

Your cat converter has been deleted so you really need a dyno tune or a well sorted private tune to fix that, the TORS tune is not rich enough. As Keith said check your map tubes, also make sure they haven't been pushed onto the sensor elbow fittngs too far as this can block the tube.
Many of the early Tbird owners deleted or blocked the SAI feature, there should be plenty of info here on that, search the first three years.

As i once read, tho not sure, i believe that only tells the ECU whether or not to throw an error code is SAI has an issue. It doesn't turn it on or off i believe. Plus triumph has said the SAI was never enabled in the first place. The noted the emissions were so low with the initial release of the bike that they turned it off on the bikes that had it installed and removed SAI altogether in the next year or 2.
However, with all that said, for whatever reason it DOES affect popping, and regardless of whether the box in tuneecu is ticked or not. Take off the left side cover and pull off the rear hose to the SAI and take a piece of plastc bag or whatever, put it over the SAI nozzle, nipple whatever u call it, then shove the hose over it. Mines been blocked like that since i got it in 2009 and it eliminated the popping quite a bit. Not 100% but mine pops very little. I would also install the tors tune, as it ill run better with that even if you have stock pipes.

Leethal, you were right on the money about the MAP tube elbow going into the map sensor!
When I changed the plugs I pulled the map sensor off on one side to get to the plug, I had it pushed up way too far.
I blocked the SAI with a thick plastic bag. Loaded up Silverfish custom tune. Checked oxygen sensor, uncheck SAI. I'm about 300 miles in sofar. No backfiring, still got some popping, but WAY better! Also bike seems to to be a lot smoother with that tune.
Now I just got get a belt and some rubber lol. Belt is ate up on the right side. I suspect it spent some time out of ailment. I'll check bearings when I get into that. But bike feels great. I can I take my hands off the handle bars and steer with my butt ????.
Was looking at the Metzler 888 Marathon ultras. Any of you tried them?
I'm a daily rider, so looking to get some miles.
