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.
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 Checked the setting and tried other channels too with off course changing the wire to the correct pin. None of the p259 channels work. :-(
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.
Changed the settings but still the free air percentage is 26.
