Idle issues

[duckduckgo]

I just installed a full exhaust system on my 2009 Monster 696 & sent out the ECU to be flashed by Rexxer.

Got the ECU back, bike starts up fine with the fast idle on but once it's turned off the RPM's gradually lower and then it dies.

If I keep it around 15-1600 RPM's with the fast idle, it stays running just fine.

Had zero issues with this prior to the new exhaust/flash.

First thing I would do is reset the TPS.  Scan tool is needed for this.  If the TPS setting is not correct the ECU does not know where idle is.

What howie said.

I have a similar problem after a 696 rebuild post head-on collision. Would be very interested in the steps to DIY reset TPS via scan tool. 

Went deep down the rabbit hole on jdDiag and Siemens ECUs for the 696 and never got the tool to connect with my cable setup after several combinations of ignition switch, scan, connect, and all that.

Don’t want to hijack the thread but if OP gets their TPS reset on their own, it’d be great to hear the steps. Otherwise I’m planning to take my bike to the shop and have them do it.

Doesn't the TPS on the 696's automatically reset every time the ignition is turned on?

What brand ECU on the model?
My Hyper 1100Evo had the Siemens ECU and I was told two versions of TPS reset, one that it reset each ignition cycle and the other was that you needed to fully cycle the ignition sequence three times on to off to reset it. I did the latter to be sure. Other than that the factory equipment can check it at a shop so equipped. If you're the tech type you might have some success with aftermarket equipment. Ducati have been quite effective in locking up access to the bikes electronics. The issue is finding a tech you trust or upskilling if you have the aptitude for electronics.

Sometimes it's better to give those jobs to a trusted tech and put the time towards the overtime to pay for it. I know the pride of ownership/DIY thing is strong but some jobs require specialist equipment and knowledge. Those of us from the analogue era did all our own work, but nowdays investing in specialized electronic tools is expensive. This is not a criticism of anyone, but I wish my customers would focus on keeping their bikes clean, servicing their chains and managing their tyre pressures and condition.

Word is that the guy supplying the Ducatidiag pirate software got closed down, but some have used the Guzzidiag software with mixed results. Rexxer may supply a tuning/diag unit for this model if you want to handle it yourself. Your Rexxer tuner should have the equipment to do it if the turn key method doesn't yield good results.

I forgot there was a three key cycle reset for the 696.  Might be worth a try.

If that does't work then follow koko64's advice.  Nice thing is the tech and the computer can talk to each other.

1st one on top left w/Siemens/Mitsu Serial Cable

Once you have it all running . . . A little bird from Italy, once told me to close both air bleed screws, one at the time and then open 1/4 turn at the time. >>> Close one >open 1/4 turn, close the other one, open 1/4 turn, then go to the other one and one more 1/4 turn >>> when you get to close to 3/4 to 6/8 of turn, your idle should be around 1K . . . DO NOT FORGET, you need to do this when engine is at operating temperature of at least 80°C . . . AND once your idle issue is taken care off.

Another thing, when you're turning the key to the ON position, TAKE YOUR RIGHT HAND OFF THE THROTTLE, the slightest pull on the cable will open the throttle valves thus altering your TPS 0 setting

If you still want a tool to do your service reset and TPS reset, contact these guys to see if they still have some diagnostic tools laying around, http://technoresearch.info/

Oh, nothing that a good WeissenBier cannot make you remember, apart from this, "Another thing, when you're turning the key to the ON position, TAKE YOUR RIGHT HAND OFF THE THROTTLE, the slightest pull on the cable will open the throttle valves thus altering your TPS 0 setting" . . . Also, leave the fast idle lever alone until after the gauges have done their sweep . . . A reminder, just in case

Really helpful, thank you! Did the 3 key cycle - no change

I also emailed the guy who did the flash (he's been wonderful in helping to diagnose) and mentioned a bad/clogged MAP sensor, which apparently controls the idle under 2k rpms, which checks out in my situation. Had no idea. This duck is high miles so that's another thing I'll be looking into as well as checking/cleaning hoses.

...speaking of, I can't seem to find a clear answer on where the MAP sensor lives but I think I *might* have spied it - is it on the rubber hose attached to the vertical cylinder? Is there just the one sensor?

Thanks again

[koko64]

It can expensive replacing parts without proper testing. The factory diagnostics should pick up a code. MAP sensors often live off air boxes or on the end of a thin vacuum hose running to an intake stream. You have a few sensors with the Seimens ECU and I'm referencing my Hyper from memory. Ducati specialists like Speeddog or Darrkmonster will know your model specifics.  Howie has probably forgotten more than what I know in total, so you're in good hands with these guys. Any strange fault codes appear on the dash ? Sometimes they appear briefly on start up then go to the ECU memory. Try to scroll through the dash options to view a recorded fault code, your owners manual should list some fault codes. Otherwise get the codes read by someone so equipped

[Howie]

You are looking at the air temperature sensor.  The MAP sensor is located between the manifolds.  There are two small vacuum hoses going to it. 

Do pay attention to what koko64 is saying.   If you plan on diagnosing your fuel injection you need some sort of scan tool and a decent manual.  If you plan on doing your own work beyond basic maintenance you need a decent manual.  Your tech can read live data as well as codes.

Technoresearch was an excellent tool.  Today?  Dunno.  They seem to (pun not intended) gone whole hog on Harley and Indian, though they still have the Socio Complete for European and Japanese, I don't know if this works on Siemans.  Maybe DarkMonster620 can elaborate.

Woah, interesting. This would then suggest that if your fast idle lever is anything but full-off when you start the bike, your TPS zero setting will be off as well? (AFAIK the fast idle simply cams the throttle body valves when you engage it.)

[Speeddog]

The bike ran fine, you changed both the exhaust and the ECU, and now the bike doesn't run properly.

The chance of some other component failing or somehow being compromised during that bit of time is quite small.

Best practice is to concentrate on the stuff that's just been changed.
