The South Africa spec vehicles didn’t have EGR and still had the MAF.

I cannot see how a company would fit a part that’s not required to its range when a significant saving could be had by a bypass pipe on that market.

Even the old Defender 10P was a pig of a vehicle with the MAF disconnected - every dealer service I knew when they hadn’t refitted the plug as off throttle response was horrendous.

Tuning for a while I tested quite a few and same outcomes.

Mine has always driven the same with MAF connected or not, working or faulty, my own play around fueling tune made no difference to autobox changes and I have run MAF plugged and unplugged with both the td5 auto controller and the V8 auto controller and drove as per the characteristics of each controller.

I have tested with both a good and out of range (I think it just needs another spray like last time) MAF too.

At the moment I am running stock 10p tune , EGR deleted physically and in tune, MAF in place but unplugged and deleted in tune, stock MAP sensor increased to its max operating specs in tune, and wastegate modulator set in tune to allow 21 psi from stock turbo (which I achieve and have logged)

And because I do short drives to the shops and back I have set the temperature to 70 celsius from dead cold until it really gets there then increases as normal, stops it revving high and not locking when I get out the driveway, coz the shops get to me faster than the temp goes up.

I have read a lot of posts on various forums about MAF operation on 10p motors but because my bloody car is in my driveway NOT suffering from it being disabled I will carry on experimenting and learning.

And so far so good with no fuel cooler too. but I am waiting for a really hot day to go for a long spin to get more data.

No where so far (I am happy to be pointed in the right direction) have I found any FACTORY documentation re 10p motors and MAF other than in relation to EGR.

So what happened to my Discovery 2 today.....the dog farted a stinker on the test drive

Well got the FPR gasket and fitted, just a lazy 45 minutes of cursing (used a rubber band and cable tie to hold the gasket in place when placing it) and then purging, took a lot of goes till the fuel filter stopped squealing like a baby pig, then started and it purred, much much quieter than the D2a had driven up and much much quieter than I remembered when I parked it there about 3 months ago.

While sitting and admiring and taking the short video, the ground below sprung a leak, well at least the fuel hose did, that is the slide on slid off! Not even this could dampen the joy so to speak

Then wanted to see how hot the exhaust was, so held for a minute or so, it was hot but 'holdable'

Turbo boost controller was at the min position and barely got to 5 psi on a rev, turn it up and 10 psi then a bit further and 15 psi, then boosting 20 psi at 3000rpm, that's enough for first time... Turbo is working it seems.

So now to check for engine temp, the Nanocom hooked up and the EWP controller (EWPC) display together, the Nanocom got to reading 88 deg pretty quickly, the EWPC sat on 24 degrees, so bled the system again and heater on high and finally the temp on the EWPC rose and rose whilst the Nanocom sat steady on 88.8 degrees. That is the water temp rose from 24 to 99 degrees on the EWPC whilst the Nanocom did not change temp at all, hmmm, can a temp gauge be stuck??? The dash gauge off course was giving nothing away all this time and just sat on half and in the words of Pauline H, Please Explain?

Turned off the engine and the EWP and EF kept on as it is supposed to do and dropped the temp by 10 degrees in a couple of minutes

We did some temp readings of the coolant pipes and externals and the exhaust whilst running was measured after some time but it must be said that the area around did not feel hot. The temp readings on the upper radiator hose fittings were exactly matched to the EWPC display

Excited you beatcha, but a distinctive whine became apparent in the aux belt around the Power Steering Pump, maybe this was not heard before because the engine was nosier but it does appear to be a bearing of some kind. Is it a case of change the pump over or can the bearing be replaced - remember changed out the old waterpump to a new one with the impellor cut away but this should not make a difference to the

I’ve stopped messing with my D2 for a while.
Funds directed towards another pursuit and until I get all the gear needed that’s the way it’s going to stay

What happened to my Discovery 2 today? ... Well, yesterday I picked it up, found this thread last night and am now wondering if I made the right decision

It's booked in with an Independant specialist tomorrow for a post purchase inspection, yeah I know it should have been a pre-purchase inspection but I liked the look of it so I just bought it and hoped that it's ok. there's a few bits of plastic which need replacing but overall its not in bad condition for a 22year old, 218,000km vehicle.

Looking forward to some beach days with the kids, I haven't explained to the wife about some of the 'extras' I want/need for these beach trips.

Cheers! I'm up in North Lakes.

I'll let you know when next we plan a trip, probably next early year.

Got these wonder who else runs them in Australia on the D2?
