This page is for the 2009 University of New Hampshire FSAE. I'm sponsoring this years car using a VEMS econoseal v3.3 ECU from the webshop with the following basic specs:
250kpa map
8 IGBT coil drivers
VR primary trigger
30v Flyback
SD Logger
The engine for this project is a 2007 GSXR750 motorcycle engine (often called a 'gixer').
Trigger is a 24-2 trigger wheel that looks like this:
After going through a few different firmware options I was able to get 1.0.78 to fire off spark and set the timing via timing light on the trigger wheel (*not* an easy task on a bike engine!)
Current issues:
1) I added an EGT chip (AD597A) via the instruction's on Rob's EGT guide: http://vems.hu/www.vems.co.uk/VEMS/egt.html
but megatune only flashes between 0 and max. I have not yet probed the connections with a multimeter, but will do so next. The only thing I didn't do vs Rob's guide was short C44, because it did not exist on my V3.3 board.
2) The wideband is not providing any feedback at all. I need to do some hardware diagnostics.
3) I have been unable to get 1.0.73 to send spark to the coils using an identical config to my 1.0.78 setup.
