That's a 7SM ECU, right? Did you select California 1400 in the GuzziDiag config?

Buggered if I know. Can't think, must sleep now. I reckon you should try another cable. Hopefully, someone else can chime in with and be more helpful.

Hi all, thanks a lot for this thread. Already proving helpful, although possibly not conclusive!

  My '99  1100es quota was running great (well ok but it had been unused for three years and after sorting out the sludge out of the tank and other lay up bits was running fine) when about 5mins out developed an alarming misfire, wouldn't rev and I managed limped home at about 20mph.
 
I was always planning to obtain an ECU diagnostic to try some fine tuning, unfortunately it has become a priority.  Downloaded the guzzidiag onto an old Win7 netbook and it works great with the lonelec leads.  Trouble is I was expecting to see errors and drop outs in RPM associated with engine timing issue, or an error code; but I didn't. 

  Kind of back to basics now, tried new plugs, no joy.  Will check leads etc but also tempted to swap out the timing sensor anyway, anyone know how to check them? 

  Either way I am kind of looking forward to

a.  Getting the flippin' thing running.
b.  Getting it running smoothly as standard
c.   Maybe even making the odd tweak, not sure I can write a map to the old ECU 15M I have though.

Either way it'll be fun, any top tips for the older stuff aprreciated, especially those quota related.

All the best
Ian

If the timing sensor is faulty, you'd get an error.

After being in storage, maybe a clogged injector? Pull the injectors and test them.


Oh, and yes, you can read and write maps to the 15M.

I had a set of cables that worked for about a year. Loaned them out, user said they didn't work. So I tried them on my bike and they no longer worked. Acted just like the bogus one I ended up with first.

Bought another set (same cables off of Amazon.com) and they have worked since.

So you may have had the right cables but I've heard they do not suffer stray static electricity very well so they may have toasted on you. But faux cables or toasted ones act the same: will not connect.

Cables and com ports,

I found the link to the cables on Amazon I think from this topic. They have worked fine so far.

On the com port, somehow my PC device decided to add a com port. Now I have two to chose from. Sometimes the first one listed works, sometimes the second one. Try both ports before giving up.

Good luck,

2012 Stelvio 8v ABS

Running GuzziDiag and all seems OK except it appears only 1 of my Lambdas is displaying.
When it's cold they both show 0, see below even tho it wasn't running at this time it still shows this when it's cold.


As it warms up only Lambda1 appears:




Should that be how it looks. Loaded Mark's latest 2 Lambda Map, but it's always looked like this.

Thanks

Larry

Is it like that at normal operating temperature too? In your picture it shows an engine temperature of 59 degrees. I guess this is just a coincidence but the lambda signal is ignored by the ECU below 60 degrees.

You now have a map with the lambdas switched off, so it isn't currently a problem, but I would have thought that if your lambda really was defective, you would have got an error message on the stock map.

+16 CO Trim?? Is that the recommendation for the map?

John.
From memory it doesn't matter what temp it's  running at the 2nd Lambda doesn't show. Doesn't matter which map either.
If the CO trim is set any lower than that it idles really rough and low.

Thanks

It's unlikely, but did you check if the lambda cables are damaged or if it's not plugged in properly?
I find it strange that you never got some kind of error message with the stock map if your lambda really isn't sending a signal.

Maybe the CO Trim you now have is a result of this problem. I don't know, but I imagine Beetle doesn't suggest a trim of +16 for his map. The fact that your bike runs poorly below that is an indication that something else is going on. I wonder if your ECU has somehow "learned" some incorrect adjustments over time due to the missing lambda signal and is continuing to apply that to the new map? Did you reset the auto learn parameters when you installed the new map?

Did your bike idle roughly with the standard map too?

Hi Xlratr
I did mention the CO to Beetle and he said it should be close to Zero, but it runs like a dog at that and is hard to start.

I've reset the auto learning thing numerous times and it doesn't seem to make a difference.

I'll check the cables and if that isn't the problem  I'll put the stock map back in and see what happens.

Thanks

Larry, I just sent you the very latest map with your speedo correction. Try it at CO=0 first and let me know.

I suspect something else it happening with regard to the rough idle. How's your TB balance?

Thanks Mark.
After checking and spraying the Lambda cable connections I loaded the map and did the whole reset thing - correct me if I'm wrong:
Idle screw (the little brass one under the left TB, right one's already in)all the way in, (3.5 turns?). At 85c I reset TB to 4.80 and auto learn. Set Balance at 3750rpm. Reset TB and Auto learn. Balanced idle - 4 turns out on left side. This is with CO at 18. Reset CO to zero. Idling like a dog and way out of balance - couldn't balance it. set CO trim to 18 and it runs OK and balances - reset TB and auto learn. BUT NO LAMBDA 2.

I disconnected the Lambdas and the reading disappeared on GuzziDiag when disconnecting the left one, but nothing when disconnecting, wobbling, reconnecting, tapping etc the right one.
Guess it's broke :(

Thoughts ??

Thanks

Larry

I think it's the air bleed Mark.

Larry, is this a sudden development or has it done this since rollerisation?

Phew. How long ago did you rollerized it, Pete? If not that long ago, it shouldn't need a TB balance yet.

I don't think it was that Pete. I've just looked through my emails and I queried Mark about this back at the end of August last year as I couldn't get it to idle properly without the CO trim being at 16+, but can't remember if the Lambda was working or not. I know I installed the stock map prior to send it up to get rollerized.
I think I'll have to get a new Lambda, you don't have one lying around by any chance do you?

Thanks

If you're going to keep using my map, you won't need a new lambda. The map is open loop, so the lambda signals are ignored. You will still get an error, however, if the lambda sensor heater fails.

I would ignore the fact the second lambda shows no signal. There's something else amiss, either with the tune, or the map.

There are no faults showing Mark.

I think I'll load the stock map tomorrow and see what happens.

Larry, there is no way you should need 3 or 4 turns of either of the bleed screws if the high speed balance is correct. Both of mine are closed and it is in perfect synch. I'm also thinking you turned the wrong screw when doing the high speed balance. It should be the one that adjusts the length of the rod going over to the right side TB.

Yup. Pics please Larry of what you touched. I still think it's the air bleeds but let's be sure. If you can't post them here send them to me and I'll post 'em up. We'll fix this, not a problem, but it's a matter of using a proces of elimination and via the web, that's hard.

This is the high Speed adjustment screw. The air bleed is tucked up behind this that requires an Allen key to adjust- there's another one on the other side. I haven't touched anything else
