Hi Trikers,
I have a 2017 Boom Trike from Germany, fitted with 2 litre Peugeot engine and automatic gearbox. All sensors are reading ok. When I need to stop or slow to walking speed to give way to traffic, the engine revs keep slowing down until the engine stops, unless I bump it into neutral and pump the throttle to keep it running. It will start after stopping but will repeat that behaviour at the next stop. 3 different mechanics / auto electricians have said the ECU has "locked up". The timing is 8-14 degrees retarded when it should be advanced. It is down on power on what it should be. It uses a bit more fuel than I think it should. Evidently Boom have fitted an after-market ECU which is readable but NOT programmable, the settings cannot be changed.
Q. Does anyone know of a way to re-map the existing ECU?
Q. Does anyone know of another brand of ECU, compatible with this engine and gearbox?
Q. Does anyone have a solution to this problem?
Many thanks, RFG
