Makeitfit suggested in my submission about Terrano 2 auto mpg experiments that I remove the EGR. As I asked before, what is an EGR, where is it, what does it do and finally will it safely possibly improve mpg without affecting something else?? Will it affect the next MOT? Cheers.

re tyre pressures and mpg I remember in 1995 when I bought a Patrol 4.2 GR , the thing slid in an any sort of wet when briskly going round corners and roundabouts. West Coast 4x4 put me straight. The original tyres were designed for the middle east market with abrasive sandy conditions. The...

Thanks. What and where is the EGR. What does it do? Cheers

Any other suggestions to experiment with??

Excelent results!

Hi guys. I changed my Patrol 4.2 manual for a 1998 Terrano 2 auto last December and was dissapointed with the mpg of 21 to 23 mpg. i asked for info on this forum about remapping etc at the time but remaps on this vehicle need the ECU removing and it costs too much. However, I embarked from then...

does the lack of response mean no one knows how to adjust idle speed??

Can the idle speed be slowed, I fitted a Speedbox and if I turn the adjuster for power the idle speed goes just over1000 and seems too fast for my T2 auto, it wants to creep too much from standstill!

I have fitted a Speedbox to my Terrano 2 1998 and if I turn the adjustment screw to make make power gains, the idle speed increases. How do we adjust the idle speed back to 750 or so. But if I turn the box adjuster up more, the engine spits back so that is probably too far. If the box is turned...

So where is the ECU, behind the dash or passenger footwell, presume behind the carpet? What is the black box under the drivers seat? Theres so many connectis and wires under the bonnet are any of these wires possible connection points? Can the use of Scotchlok connectors avoid soldering? Thanks...

I've seen the pics of fitting the Speedbox to a Bosch equipped vehicle with a large round plug. My car does'nt have such a plug. On the left side of the engine looking from the front is a row of square plugs. Donator store selling the Speedbox say fitting is "not easy", but they do offer a box...

what are sliders? I just thought the caliper pistons are not realeasing all the pad grip???

Thanks for the advice. I was zoning in on the Speedbox model but a bit cautious cos it comes from Italy so thinkin the instruction might be a challenge. At this stage I dont know what diesel pump I have or where its connector is, assuming these have to be accessed to fit the device. I already...

I had some 100w rally bulbs on a Patrol years ago. One headlamp glass cracked when vehicle stopped through overheating on a cold night. Later I had the connector block melt on the other. Nowadays the latest Xenon bulbs like nightbreakers give better light with no increase in current or heat. I...

I'm told that to remap my ECU, it needs to come out to replace or reprogramme the chip. (1998 Terrano 2 TD intercooler automatic). It must not have a diagnostic plug as later vehicles. Has anyone done this sort of thing to improve mpg? I live in Burnley so going hundreds of miles is...

yes to both questions, overdrive swith is in (on). Any one any other tips please? How will the K7N filter fit, straight replacement of the large black filter cannister? Thanks G

MPG I recently got a 1998 Terrano 2 2.7 diesel automatic and I'm only getting 21 mpg. Has anyone any advice to improve this? Any views on tuning boxes or ECU remapping? Im told the ECU has to come out to get to the chip on this older model. Im in Burnley Lancs. I traded in an old 4.2 patrol and...
