Jan Thanks for your post Can you send us the software you have ? As I said before if I succeed in making a cable I will provide all details to this forum and offer a cheap cable to buy (about £50 at a guess) Thanks Alec

Looks like someone has copied the cable already when it's 120 euros , that's a nice profit on the actual cost of making the electronics , but still good value for money given the alternative I have tried the gas gas software with my home made cable but did not work . It's still the ossa Kscan that's the missing for me

Great info thanks It's all depends what's in the communication box The ossa service manual shows a "signal level convertor" as the communication box If that's all it is then it's a simple device converting some signal (I.e 5v rs232 or 3.3v rs232) into the RS232 for computer This hardware I have I'm my drawer . I have been doing some tests already with Kscan software from Gas Gas website . No luck so far But if I could get the Kscan for Ossa software then there is a good chance it will work Can you help ? The owner of that cable will have the right software to go with it If I succeed in my mission I will post all the info Then we will all have the means to check our bikes with a £20-£30 cable

I'm in Bridgend South Wales CF32, I'm going to have a go at making my own cable, £700 for a cable is twice the price of the ecu itself I work as an electronic engineer , the only problem will be if the cable is encrypted to the software and ecu somehow What is a hotter plug?

Exactly the MAP should read the manifold pressure but it's not connected to the manifold (that space between the throttle butterfly and the engine) it's a barometric pressure only sensor on the ossa) MAP sensors can do both vacuum and pressure above atmospheric . They are traditionally used for barometric pressure reading before startup(takes a measurement before engine starts ) but this is not possible with the ossa without a battery.

Don't know what map it has or if the TPS has been set with the software ,

I'm new to this forum , just bought a 2012 Ossa tr280i , not really happy with the engine feel in bottom end and it keeps on flooding. So I'm trying to understand how the FI system works , I understand FI but I don't get how the Ossa does its calculations , my MAP sensor is In the outside air not the manifold , so is the amount of fuel dependent on the throttle position? (With some tweaks for engine temp etc) so the map sensor is only monitoring the barometric pressure ?
