Anything non-factory wired to aux outputs such as fuel pump relays or boost valves? No alarm or immobilizer, have a boost activated Hobbs switch for secondary pump but, otherwise nothing else. Boost activated secondary fuel pump is just fuse connected direct to battery. Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 3, 2023 Report Share Posted October 3, 2023 The only thing that can keep the ecu alive would be a back-feeding aux or something faulty in the ignition circuit. Since you have added E-throttle, and you are also saying E-throttle dstays on all the time, it sounds like the issue is there somewhere. Does the ecu power down if you unplug the e-throttle connector from the board? Can you attach a copy of your current tune - in the one you attached at the top you have e-throttle relay assigned to aux 9 which should be the motor?
