Yep, thanks folks - I managed to get in touch. Andrew

Bump ....... Does anyone know how to contact COSMIC? I tried to send him a private message but he cannot accept them. Andrew

Hi Folks, A few of us from Manchester GLASS are planning to spend a day or three during the half-term hols later in October doing a few lanes near to the Scottish Borders. I've no problems in finding out about those in England - Trailwise is useful for that. I know about a lane from Tibbie...

Yes, you need a pen, paper, a bath towel, a pin and a voltmeter of some kind (a DVM or DMM are fine). Do the following: 1) Find out what colour cable is connected to the MAF output. I assume that those shown earlier in the thread are correct for the 2.7Tdi engine. For a ZD30, it is the red...

For gawd sake, the OP was only asking how to check whether his MAF was goosed or not!! The easiest and quickest way to do that is to follow the process in the workshop manual. You don't need ECUTalk (and all the aggravation that many suffer getting it to work) to do that - just a DVM that...

You guys are missing the point. The workshop manual specifies the voltages at the MAF with the engine hot and in neutral - not my rules about how to measure the MAF but Nissans. Measuring under load may or may not affect the readings you get, I haven't a clue - but nor have you because you have...

All you've done is tell me how you would measure the MAF output volts. You could readily do that with a Consult (or ECUTalk or any other Consult-alike). That is a (dead) easy part. The difficult part is replicating some test condition for which Nissan have published expected results. The...

There is no spec for what the output voltage should be under all possible load and engine speed conditions - so it just isn't possible to test under load. If you think otherwise - please explain how. Andrew

Identifying the rate at which the output voltage rises with airflow is exactly what you do need to know. The means for measuring that is specified in the workshop manual - and it doesn't require it to be done under load. Attempting to test under load (not that it is really possible to do that...

Much less than £100, I think. The one labelled "Ebay_MAF" in graph above was about £60. As you can see from the graph, it measures pretty much identically to the factory original - so test first. Even £60 might be a waste of money if the original is fine. Andrew

The workshop manual for the Patrol says the output should rise linearly to about 4v at 4000 rpm. Whoever wrote the manual must have forgotten that the operation of the turbo and the egr valve affect the readings (or more likely, they tested the MAF on a testbench, not in an engine). If you...

Indeed, yes - it was called the Cuthbertson. I've seen two of them - a green one at the Motor Heritage Centre at Gaydon (still there AFAIK) and the other at Lix Toll garage near Killin in Scotland (see photo) - unfortunately that was sold when the garage changed hands and is now in South...

Yes, indeed - me too. How to make chicken chasseur Andrew

My 4x4 is part-time 4x4. Does that mean I can only trype in this thread about the part of the time when it is in 4x4 and not about when it isn't? There are two times when I usually use my 4x4 in 4x4 - when I go greenlaning, but only for the part of the time on the not-tarmac bits when part...

The turbo starts producing boost pressure from around 1200rpm. At 55mph in top, you are close to the engines peak torque - and the turbo will be hitting its maximum boost there too except when you are on a trailing throttle. You are getting decent fuel consumption because you are driving a bit...

Y61. At 65-70 solo, I'd expect to get around 27-28mpg. Andrew

At Easter, I towed our 1500kg caravan from Oldham to Killin and back - 22.7mpg one way and 20mpg the other. Andrew

I guess that would depend on what state the EGR valve is in. If it is stuck closed, it will not make any difference. If it is operating normally, the experience of the Aussie lads who routinely do this to Patrols suggests that it will increase peak turbo boost pressure by 4-6psi. On a ZD30...

Yeah, me too. I only did because I had little option. Firstly, have a close look at the turbo's VNT linkage. You should see an adjuster on the rod and also a stop screw with a locknut behind and to the right of the adjuster. You should see some yellow (sometimes white) paint on them put...

Yes. I haven't yet received the Dawes valve. It'll take a while - its from the USA. I'm not expecting it for a week or two yet. No, performance is fine. Yes, maybe we should - Sheffield is near enough. You have to remember, though, that the problem I had was because someone (previous...
