odd, hot idle on mine has always been 1.6 bar, since I bought the car new in 2010, with or without the BAS remap. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Interesting, what oil do you use and how do you measure?

Hello 4wd-junky (All)
I recently had an issue with my OP Sensor, that was triggered with a 'slow to go out or stay on' Oil Warning Light... 
Some times...(not every time) my warning light would 'linger on'... this is a short series of trials, at stand still or slow moving...with the 'fear' of seeing an Oil Warning Light I didn't drive around for a few days...seeing if things would sort themselves out...(or as is not uncommon in Defender Land...'that noise goes away') Simple fix for me... Both Land Rover and my Independent suggested the first thing to check, Oil leaking through the Sensor itself and interfering with the connections...a quick clean... flood out with WD40 and reconnect...all appeared OK...New Sensor on Order (£6-8 internet / £29 Land Rover OEM) fitted and no repeat of the On or slow to go Off Warning Light. An Ex Ford Technician (now at Land Rover) said to me that this is a common fault on some Puma Transits, and the Sensors are replaced at each Oil Change... Oil clearly seen at connection point of Sensor... Click image to enlarge More Oil within Sensor Connector... Click image to enlarge New Sensor... Click image to enlarge Fitted (During Oil Change) Click image to enlarge SKIP https://www.defender2.net/forum/topic83242.html |

I have a Madman EMS, installed the day after I bought the vehicle in Feb 2010. From then until Feb 2013, it ran on LR's Castrol Magnatec 5w30, since it was serviced at the stealer.
As soon as it was out of warranty in Feb 2013, I switched to Fuchs Titan, the one approved for Ford WSS-M2C-913C, as I then started servicing at my trusted indipendent workshop. hot idle on both oils has always been 1.6 -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

I use the Fuchs Titan as well. But to be honest, there is no pressure-sensor on the genuine engine, only the swich. So it may be a calculated value corresponding with the revs of the engine from ECU. Really odd. Do you see different pressure-values when hot or cold? |

hi Hornet,
The Madman is a complete monitoring system that is installed with its own sensors, so independent from the vehicle: https://www.madman.co.za/index.php/where-t...4-defender Thus the oil pressure, coolant temp, EGT, transfer box oil temp, voltage, etc., I see are the real live values, not calculated ones. The oil pressure sender is a VDO one that you bolt onto the engine block:
Indeed, there is big difference in oil pressure between cold and hot idle. On a cold winter morning like today (1C), the cold idle is around 4.6 bar. On a hot summer day (44C), the cold idle is around 3.7 bar. FYI, this is a photo of the Madman display in my Puma: Click image to enlarge . -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Thanks Naks, nice setup, photo must have been taken when new, how many miles are on it now?

haha, yes, I got the Madman about 2 weeks after I bought the car.
It now has 74287km on the clock, not a single drop of oil used in between services (6 months/10,000km). Goes like a bomb with the BAS remap, Alive Intercooler, and decat.  --

Good on you Naks👍 I quite like the madman, however was a little gun shy of drilling the exhaust manifold. That been said I've done about ten thou more K"s and use Penrite C3 also no detectable oil usage!
 Tomorrow will chuck the deafener on the hoist and have a bo-peeep at the sender! Good too here Blackwolf with 350Km's @ is running like a champ |

Drilling the exhaust manifold is fine - you just have to do it while the engine is running, and have someone hold a vacuum cleaner close to the spot for added security.
Please note: there was no way that I would do this myself, I left it all to the expert installers recommended by Madman
They did a top job, the only issue I've had since 2010 is that the oil pressure sender has had to be replaced 4 times, they always seem to fail when the temperatures hit 40C+ around here. So the last time we moved it away from the engine block using a 30cm braided extension hose, and that has solved the issue. Also, while the oil pressure can go beyond 5 bar, the recommended unit is a 5 bar as using a 10 bar results in the latter getting clogged up and failing due to the return mechanism not being operated throughout its rull range. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged
