Summary of change:
Installing Vems3.3 on a Volvo 244 with a B21ET engine. Taken out the dreadful K-jetronic to get complete control. This car should be competing this year in the Benelux Driftseries. http://vems.hu/www.vems.co.uk/VEMSInstalls/VDBVolvo/IMG_8646.JPG Q: what is fried if one would but +12v on a EC36/15 pin? Just hypothetical speaking. :-( A: The fuel pump relay pin can handle +12v - the issue is what current went through it? '''More info:''' That I do not know. All I know is that the fuel pump relay isn't being triggered by Vems and all other outputs do not work either. Maybe the outputs on s259 still work. A: Didn't we switch off all of the outputs in MegaTune in order to make sure that the injectors all fired? Please check in the Fuel pump/Fan/Water pump settings in MegaTune to check that the channel has been activated Q: can't get the Lambda sensor calibrated in free air. Done the test as in http://www.vems.hu/wiki/index.php?page=MembersPage%2FPhatBob%2FUserGuide and all checks out. In Megatune I've got the WBO calibration down to 1 and still I get a reading of 30,95% O2 A: Take a look at your invoice and any of the information sent to you from the webstore you should have been sent the values for the calibration - I'd expect to see numbers around 99-105 (but it will be written in hex e.g. 68 6A etc '''More info:''' pump-= 4.05V wbo2_pump_pw_zero=0x63 (99) wbo2_nernstdc_target=0x89 (137) I believe it is now set to 128. Could this be significant enought for the calibration? pump+= -4.7mV/340 Ohm A: I'd set the pump_pw_zero and target amounts to those you listed above. Then test again, you may be plesantly suprised! Normally small number changes result in large changes in results.
