I purchased a Scangauge-KR SGKR Heavy Diesel Vehicle Scan Tool for our OKA motorhome, which is powered by a Cummins ISB4.5. The Scangauge connected straight away and provides a range of data not available via the vehicle's in built gauges, including estimated fuel consumption, transmission temp etc... The product works well so far.
