Summary of change:
3.5 years ago (!) when I first bought the VEMS 3.3, I had some project for my Volvo 850. Since then I had a Maserati biturbo and so I was more involved during my spare time with mechanics than with electronics or software. Hopefully the car is 200km from where I live ! ---- '''Trigger''' This biturbo has an '''odd fire engine''' * with '''bizarre triggers''' * do you have more details on the trigger ? ** VR/HALL ? ** pulse positions R(26-08-08): 2 VR, see the ESjaavik's Maserati page (link?). "Bizarre" in a sense that this case is not (yet?)handled by Vems. so that the distributorless biturbos produced at the end were more easily equiped by Maserati with 2 ECUS, each one dealing with an 1/2 engine which is then 3 cylinders even fire. Recently I aimed to use Vems to measure C0% at idle in order to fine tune the A/F potentiometer set on the Weber injection ECU. My first issue is that I did not get the good O2 percentage for the free air test ! After you measure connection (including that you have +12V on heater+), you need to calibrate: * GenBoard/Manual/Config/WidebandCalibration starting value (from RCal measurement) * '''MembersPage/PhatBob/UserGuide - calibration steps''' ---- '''Wiring''' Document wiring here !!! email conversation suggests serious miswiring (like fused grounds) You should start from 0, documenting the whole setup * every wire you connected. * every measurement ---- '''mcd/mct dump''' Verify wbo2 config, and publish mcd / mct dumps. email conversation suggests possible misconfiguration (although not confirmed)
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
