Good day!
I own a Nissan urvan bus(model pics attached), unfortunately I hard engine problems and took it for repair .... In the process of repair my ecu was burnt, so I got another... Unluckily for me that new brainbox was stolen... So mechanic tried almost 8 brain box before he got the one that starts the bus and give good throttle response (electronic throttle)

The issue....
I took it for a long distance drive and discovered the bus does not go pass 3.5 rpm even with the throttle floored, irrespective of what so ever gear I am on... So on gear 5 the best speed I can get from her is 110km/h which might be an OK speed but it struggles to climb hills even without load... The best speed I get climbing a hill is 50km/h...

Great gurus what could be the problem, cos the silly mechanic is a lost course..

the problem is hydra headed.

Most times when a mechanic overhauls an engine and it refuses to start, they always jump at the poor engine-ecu (brainbox) and then the tinkering starts, later they realise problem was mechanical and by then the auto electrician (rewire) has already done irreversible damage to the engine ecu.

As it is I know your original engine ecu is very expensive, and scarce, that's the reason they tried so many and only got a close match, but not a match.

Presently vehicle is in limp mode or not working well mode

Best bet is to find the exact engine ecu, Fix up all the abused wiring and vehicle will return to factory specs.

Good luck.

Thanks bro... The only problem is I can't identify the correct brain box number.... So its gonna be a herculean task.... Plus the bus has no diagnosis port to scan the vehicle...
Thanks

Costee:
Where was the key reprogrammed to the bus when the ecm was replaced? Or maybe it has no immobilizer?
You may post the VIN or by PM

GAZZUZZ:
just ask the mechanic for your initial engine ecu, it is written on the back.

Then contact 0803 427 0856 membis for a replacement part.
