Dennis Wiese Posted May 3, 2010 Report Share Posted May 3, 2010 Link G1 lpv14 problems. Second user unit. Problem1 : high scnc/cyl error count Experiencing Scnc/Cyl error - getting anything from 134 â€“ 175 counts over 5- 10 minutes of running at high rpm under medium loads upwards ,seems fine off load running in na mode ie under 100 kpa., experienced while re calibrating fuel & spark tables. All wiring checkâ€™s out solid when tested with dvm. Noticed no user options for dizzy input signal conditioning. Using break out box with 6 inches of cable for ecu install , the VR â€˜s are unshielded for the last 6 inches, not had problems before using other types of ecu in this configuration, will be installing screen cable just to cover all angles and to scope system for any signs of interference. Vehicle ran faultless before on oem ems. Problem 2: no wastegate control. wastegate output only pulses when ecu switch on for a few seconds then nothing. used regulated air supplied set to test pressure connected to link G1 map sensor, set option to perform wastegate regulation as per instructions for testing wastegate control in G1 manualâ€ nothing happens no oscillating what so ever in the valve, constant nothing no ground what so ever on the output wire. Also noticed regardless of changes made Wastegate DC shows 102 %. What about an output transistor damaged, unit brought secondhand in poor install condition. Any schematics of Link G1 LPV14 circuit diagram to check output transistors rather than send unit away from UK to NZ .have some experience working on other brands of ecu ,could backward engineer output drivers if need be. Any help greatly received. Quote Link to comment Share on other sites More sharing options...
