I have an AOR Matrix, which is a two wheeled off road van, its GVM is 2,400kg.
To change gearing you need to change tyre size, diff ratios, transfer case ratios or the actual gears in the gearbox.
It may mean it is better at pulling itself up a hill at a consistent speed where other defenders may struggle. Adding more torque wont change the revs at a certain speed in a certain gear, it will just make the car better at "pulling" itself and whatever you have attached to it around. For example in your car with its current gearing 2000revs in 6th will always equal 100km/h. So far it's all good.Revs and gearing have a consistent relationship. The chip was fitted by a previous owner and I considered removing it, but then I read up on it and decided it seemed OK. Steinbauer says its chip does not increase fuel pressure. I think if the chip is making more torque than standard then it should need fewer revs to maintain the same speed in the same gear.įor example, mine is only doing about 2000 revs in sixth at 100 km/h, but I have heard people say they need more revs for the same speed.Īnyway, that's just my unscientific guess.Īlso, a post above talked about fuel injectors being damaged because fuel pressure was increased by a chip. Since replacing them, removing the chip and having a proper tune applied to the ECU it's more powerful, better fuel economy and the injectors have not had further issues. I will share with you that a DP Chip (which the previous owner had had fitted prior to our purchase) destroyed the fuel injectors (due to the signals it intercepts and alters on the fuel rail pressure sensor causing the ECU to receive false values and therefore increase fuel pressure further) in our 2011 Ford Ranger costing $350.00 each x 4 for the replacement parts.
Not sure what the DP Chip of Steinbaur Chip cost either but the tune for our D4 TDV6 was $650.00 from BAS uploaded via my IIDTool - I believe that's much cheaper than what I see the 'chips' often advertised for! Once you've done that you'll want to go to BAS Remaps, Powering the Landrover tuning world! – BAS2RRC Remote Remap Control Landrover Defender hybrid turbos, Remap, Tuining, Intercoolers and more and speak to Pete (who specialises in Land Rovers only) to purchase your tune. There's heaps of threads about these types of products from companies that suit a wide variety of different brands and models already.
