KTM TPI Continental Synerject M3C

Post by R Horn »

Looking for XDF file help or files for Continental Synerject M3C ECU's I can learn from.

I purchased BitBox and Bitedit so I can Read and Write them with BitBox. The BitEdit definitions are a bit lacking at this time so switching to Tunerpro which I used prior for my Buell.

I have bins and looking for some help :)

Hello,

I'm very interested in the progress you are making with this. I just started with tunerpro and it looks great but steep learning curve.

Any help with it would be greatly appreciated.

I am also trying to figure this ECU out. Bought a XDF from Oldskulltuning who hangs around here. The maps are identified correctly but the map offsets are not correct atleast not in the ignition map which makes me unsure about the rest.

I have also spent some time in Winols trying to identify further areas of intrest:

HEX: 0a000 12x8 16bit
HEX: 08410 20x18 16bit

It is repeating itself just like several maps do i guess due to map1+2 selection

Dear customer,
map offsets (start/end address of maps) are 100% correct, also for ignition maps.

About this address: HEX: 08410 20x18 16bit
it is already present inside our xdf, named "target lambda", see attachment.
It has been double tested with our customers.

If you have any question please feel free to contact us by email: oldskulltuning@gmail.com

Thanks for a swift reply both here and in the email. I am a happy customer. The reason I don't believe the first ignition advance numbers is that almost all 2 strokes have a 5 deg ignition advance at 0%TPS/1000RPM and the map indicated 15deg at which point the engine would be almost impossible to start.

After the latest adjustments to THE XDF the ignition maps fit excellently. I have attached a graph with the ignition curve for 100% tps.
Image
Green+dark green= TPI map 1 and 2
Blue+yellow= Map 1 and 2 for the old carbed 300
RED= Map I have developed on the dyno for racing with the carbed 300.

So the new TPI have more ignition advance, most likely since the old bike had a very conservative ingition advance map since it lacked TPS so the map was a compromise to avoid part throttle detonation. The TPI still have a slightly conservative advance in the 2000-4000RPM area, more advance in this area gives faster throttle response but wont make much power. So the OEM curve is more traction oriented.

Another interesting find is that past 7000RPM the ignition wont continue to retard which is the usual for 2 stroke engines to make it stay on the pipe longer. This is most likely to make the engine go flat in the power curve to make the rider change gear. The decreased timing the red curve have in this area gives way more power. But you need quite some balls to lack power @7500RPM with a 300TPI....

For the moment i am trying to find if it is possible to do adjustments to cold start enrichment. Since me and a few friends use TPI bikes for snowbiking where the riding temp is -20C so even with radiator cover you have problems keeping up the coolant temperature so the EFI excessively richens the mixture.
