Motorhome owner Tony C from Essex, recently bought a Iris Bus conversion, & the engine wouldn’t rev over 2500rpm , I supplied a BSI ( Body Systems Interface ) ( Body ECU ) that had no tacho from factory & all was good , alternative is having tacho switched off in existing BSI, but in this case , we had already removed the immobiliser from the engine ECU, so any BSI could be installed & tried , without any programming ( as long as gearbox type matched ) . . That’s a really shortened version of what actually happened over a few months , as it was a non runner , then a runner once immobiliser was removed but with 9 engine fault codes , so many things happened 1st resolving faults one by one with ECU swaps,. Finally though Tony said it could only be a faulty tacho now & he was right. T sign tacho missing message was gone from dash & mileage showed correctly, once the new BSI was installed.
Interested in this module as I also have the same problem! Alternatively ring me on 07813568787 thankyou George
Hi George, its vantuner, I’m largely retired from doing them fully now but if you want your immobiliser deleted, allowing you to fit a used , non-tacho BSI, then i can help with that.
