The car is now running had to lower the dewll time to 2ms. PROBLEM Having a problem with the vems solenoid not working it dosent operate. It's configured under alternate boost settings. I use output EC36 pin 18 (inj 6) injector output is set to Injector 5 under alternate boost. The injector output is set to injector 5 = 32. The solenoid is klicking when changing the output to inverted and reversing to none inverted. The stepermotor driver isn't installed after the repairation. Dose this controll the solenoid? 2009-12-29Answering my own question The Steppermotor driver has to be installed to get the boost solenoid to work. 2009-07-24 The enginde is now reving through the 0-7500 rpm with a steady rpm signal. The problem is located to poor coil grounding. Installed a new ground wire to the coils and it works. Might have a problem with the box dying at higher rpm when driving in street, but i will check this later and try lowering the dwell time from 2,5 to 2. |

I had this problem before i mangade to kill the box buy running 12v in to the EC18 16, 17.
Can a faulty/messy trigger signal make this symptom? Or is this a grounding issue? |
| In frustration when the car stoped reacting as it shuld I relocated the Coil wirings from EC36 33 34 35 36 to EC18. |
| But I must have counted wrong. I missed placed two coil connectors to EC18 nr 16 17 so the box probably got killed buy this. Is this a likely explenation? |

| I have tested my vems box in a friends car but the same error accured. Removed the P259 circuit but didnt help. |

Have tried bothe the EC36 33 34 35 36 outputs for the ignitions and the Ec18 Stepperoutput but theres no reaction of life. When you are trying the outputs with bad grounding you risk (further?) damage. The coils are working when manualy grouning them fast. The injectors dosn't work. Theres 12V to the injectors, CAS and ignition. I mesured the outputs with DVM. P259ch0=16v 5v+ 4.96 tps supply 4.96 primary trigger 4.3v sec trigger 4.78v Loaded the new 1.1.50 fw on to the vems box but didn't help. I think somethings dead in the box. Don't know what to do. I have tried FW 1.1.18 and 1.1.44Alpha2 but same error. The box did work with fw 1.1.18 and 1.1.44Alpha before it stopped reacting when I was driving. |
