I'm actually quite amazed that this was so low key, as I was just looking for info on the diagnostic interface, in my bid to do my own cables etc, and came across it via Google.JDuc said:so then....this is essentially a hacked version of the ECU that's being exploited?
You would need a CO meter, to do the job properly. I hunted down a Gunson here in south Africa for a very good price.JDuc said:so then, are you saying that you could go this route and not need the VDSTS?
The differnet models and the years he says they work for is what's confusing me I guess.
he's saying that
before x year all bikes used b computer
between x and y years all bikes used c computer
after y year all bikes used d computer
when I know that's not the case??
Can you tune CO with this or do you still need a seperate CO tuner? I understand that you will need a sniffer to properly tune CO.
There's a lot of confusion here and it was discussed in detail on the thread I mentioned before. For tuning richer than lambda 1.0, the richness is indicated by CO, O2 is a noise quantity. For tuning leaner than lambda 1.0, the leanness is indicated O2. The common mistake is to say that therefore you can't tune with a wide band o2 sensor. What is happening is the lambda sensor has a couple of modes of operation. For lean it measures o2, for rich it indirectly measures C0. I don't want to go more into this on this thread. See the other thread.Aragorn said:That's what either Cliff's software or Optimiser is for. I'm a little confused about this "tuning CO"? Typically, it's all about your Air/Fuel Ratio, hence the Wideband O2 sensor.
For MyECU each map data point, specifies an o2 target index (0-7). 0 means open loop. The other indexes can be different A/F ratios.Aragorn said:Cliff, I guess MyECU operates in Open Loop at WOT, and then closed loop using a map and the O2 sensor the rest of the time?
You could feed that in as the pressure input and let the normal compensation take care of it or feed it in as the TPS. I don't know how easy that would be to tune though. Some systems connect the fuel pressure regulator to the manifold.Aragorn said:Cliff, the only other thing I was wondering about is the use of a MAP sensor to read vacuum (or possibly boost?) or is the whole system based on the TPS? I know there aren't too many turbocharged Ducati's running around, but the ability to tune your FI correctly wouuld be a start.
