Hi All,

Rode my Aprilia RSV into work today on a 35 degC 75% humidity day in Sydney and had to wrestle the throttle all the way home to stop the bike stalling at idle.

Anyway I discovered a few things when I got home that you might find interesting if you did not already know.

Hi All,

I have been playing with the automatic mixture control fn on my Microsquirt v2 running 3.83 code after a long spell with the fn turned off. ( with earlier code versions I was finding that it was not saving properly on engine shut down and I was losing the whole map and bike would no longer ...

Latest update:

I spent the day yesterday further trouble shooting the start & run issues on my Aprilia Vtwin on the latest 3.380 code.

I am pleased to say that the problems have now been resolved and as far as I can tell consisted of the following:

1) As Mike ( 24c) identified the ignition ...

Updated info , msq and datalog

I need to get it running over there so I can get ...

Hi matt ,
The only datalogs I now have are what I have posted on the forum as my laptop died and I lost all my old msqs and datalogs
Sorry

Have Mircosquirt V2 controller.

I have now upgraded the Microsquirt code to 3.830 and now nothing works. Well I have managed to get it to fire badly on ...

Hi

I have started another motorbike project, a custom CBX1000 bored out to 1425cc and a whole lot of other trick bits.( sucker for punishment ) but was talked into using a PowerArc triple spark ignition module to replace the OEM system.

Trouble is that the PowerArc product is total junk and we ...

OK more info after testing....

1a) tachcount reset and engine stalls at idle , have tried the full range of pulse tolerances and masks and no discernible difference.

1b) only noticeable difference is that resets happen less often during warm up than and normal running

2) Have separated the VR ...
