I'm running one on my wife's Honda SLR 650.
I started this thread http://www.advrider.com/forums/showthread.php?t=678178 about it.
Now I'll need to take a look on how to get a TPS signal from somewhere on my airheads...
I think that the TPS function is really missing on the old airheads.

Cheers

On the latest version of the ignitech (V88) software has been adapted to use a Bosch manifold pressure sensor instead of a simple TPS.
In the latest issue of the magazine "MO - Sonderheft BMW Motorräder" (only in german) there's an article about that.

No, Unfortunately not available online.
Don't have it myself yet. Just know the author and he told me.

This is the magazine:

I just think Ignitech is a funny name.

Not as funny as Boyer Bransden, reminds me of...


I bought a V50 Monza Guzzi recently and looking at one for that..... ( the ignition not the pickle...)

RGregor, does that article say what type/model of bosch sensor?

Yes. Part number is "0 261 230 146".
Used in Opel engines (the author is engine developer with Opel).
I bought a used one which I got today.
Will test it on my little test stand, but not immediately. I'm a bit short of spare time at the moment.

Ignitech added some new parts to their software for this sensor type, so it might work only with version V88 or higher.
At least that's what Ignitech told me.

For what I've seen up to now you could use any other sensor, as you manually have to give in the characteristic curve (you need two pairs of voltage/pressure values, characteristic is linear) of the sensor which means that as a consequence you need to have the according data sheet.

Thanks RGregor.
I've ordered the system from Ignitech including Bosch sensor. I've also ordered the BMW motorrader magazine! Meine frau ist Deutch....but I'll have to earn some credit points with her before I ask her to translate it

Next question is: 3 axis maps for airheads using manifold pressure. Going to ask Ignitech about this. Can you or Voltaire shed any light?

Things seem to be the same anywhere over the world .....

I don't think Ignitech can help here.
However, the article in the magazine shows a screenshot of the map Helmut Heusler has worked out for his engine setup (single plug, 1070ccm, 308° cam, reduced CR).

I intend to follow the procedure he describes in the article:
- Reprogram the advance curve I have now and set it as curve for each pressure value
- Optimize curve for full load
- Optimize curves for specific pressure values.

I'm not sure how complicated that will be.

nope....I barely understand the question.....are you looking at avoiding detonation by the ignition "looking" at the inlet pressure and adjusting the timing curve?
When I saw TPS I thought injection....

I do however have a shed with a light...

New territory for me too.
One thing's for sure: lots of dyno runs. Which is why it would be nice to have any sort of airhead map as a starting point.
So I suppose the benifits were measured - what were the conclusions?

Cripes! You have electricity in the land of the long white cloud!

Yep detonation is one of the parameters as is normally the case. Also, when you load up, the air/fuel mixture becomes denser and burns quicker therefore the spark needs to be retarded and visa versa when cruising or throttle off. Thats about all I know at this point!
