Thread: The Last Pre-NanoCom Land Rover Engines

1995.

Rrc got efi in 86, first diesel was the 300tdi with EDC ( which we didn't get in oz ) but neither has what you would call a diagnostic system.
You may need to be more specific in what you are after.

Hello Ian,

What engines petrol and diesel were made in 1995?

Kind regards

3.9 and Td300 Lionel.

Hello Loan Rangie,

I suppose your need for me to be more specific reflects the lack of depth of my knowledge. I thought I was doing pretty well to include an electronic distributor in my description! A quick diversion ... sometime later ... what does EDC mean ??? ... away to the internet ... Electronic Diesel Control (EDC)...okay!

So not EFI = Electronic Fuel Injection and not Electronic Diesel Control (EDC).

Is that being specific enough, Loan Rangie? Or do I need to garner more knowledge to reach your required level of specificity?

Please be aware that I am not operating from the perspective of The Dunning-Kruger effect (accessed 22nd of May 2023, from Dunning-Kruger Effect | Psychology Today). Mostly because I am fully aware that I know so little about motors and systems that are used to operate and control things. I relate it back to the fear of making an accidental contact with two wires and frying a black box worth thousands of dollars to replace. With my level of ineptitude it only costs 25 cents or so to replace a fuse. I am much more comfortable operating within the less expensive alternative.

Kind regards
Lionel

The "County", i.e. Landrover 110 1983-89, came with either the 3.5 carburettor V8 or 4BD1, neither of which had any electronic engine controls. Overseas they and the the 90 (not imported into Australia in this time frame, also had the option of 2.5 petrol or diesel, also no electronics, and in the later years 2.5 turbodiesel. These were development of the 2.25 petrol and diesel.

From 1989 these were all replaced by the 2.5 200Tdi, with petrol no longer an option except for some limited special runs.

a basic FYI about diagnostic capability:

US mandated this stuff for the 96 model year(called OBD) On Board Diagnostics.
There wasn't really a specific specification, there are versions of this idea of OBD.

Prior to this specific year, many vehicles had diagnostic systems, but were manufacturer proprietary systems only(ie. too expensive for independent operators to buy into, and hence monopolising repairs).

Its a bit important to understand the 'evolution' of diagnostics in this manner. That is diagnostics aren't just diagnostics, back in the supposed standardisation era in '96 in the US, if you (as a independent) bought a GM diagnostics system, it wouldn't work(fully) on a Ford vehicle, so you probably bought a Ford diagnostics system. What we now have with the plethora of diagnostics systems(you know the huge variety of OBD readers) .. wasn't really available in the early years.

With this bit of back info .. your question about pre nanocom landrovers is a bit misnomer-ish .. nanocom really have nothing to do with LR systems. They are just an independent electronics systems company that make diagnostics systems reader hardware.
What your question should (or could have more accurately been) was more along the lines of "last of the pre testbook landrovers" or similar ... kind'a .. sort'a.

Landrovers initial diagnostics systems was based around the vehicles communication system they refer too as "Testbook".
From what I have found about the limited capability of this Testbook environment ... first used for the 1993 model year on some vehicles. Not all, but many.
For engine diagnostics tho, this started in 1995 for the Testbook system

Loanrangie noted that on the 300 TDi EDC it doesn't really do diagnostics. In the manual I have, it does(did!) as the EDC meant electronic control of injection, TPS for position of throttle, which would need calibration if replaced ... etc. But lets not also forget ABS required diagnostics, and so did the infamous 10AS 'immobiliser'.

So in LR circles, diagnostics started in 1993 .. obviously as there was no mandated requirement to make available to the general community it was LR dealer variety only type diags.

This is why I made the point that the question was a bit of a misnomer. Nanocom simply backward engineered LRs communication system on the TD5(which wasn't yet forced to be open to the world, due to no mandate for diesel vehicles yet .. that came in 2004 in Europe! TD5 never sold in the US where it would have had to be OBD compliant.

Your question could have equally been stated like this to: Last pre Hawkeye Landrover Engines ... and basically had the same connotation.

Anyhow more to your question of diagnostics(still on the TestBook system): '95 on the 14CUX V8s and 300TDi EGR system, and then '96 on the (I think Disco only) 300tdi EDC too.

But for nanocom(that I know) any TD5 defender any D2 and P38a RRC. ie circa the years that those vehciels came to market.
This is where you can get completely confused asking the question the way you have here. You could very easily "fry by wire" a non nanocom capable, but Testbook capable, LR ... just as easily as you can fry a nanocom capable engined LR.

If you relate exactly which blackbox you want to avoid frying .. maybe this would help us to offer advice how NOT to fry such a thing!

Diesel wise my guess would be the 200 tdi

With that parameter in mind, no 300TDi needs a diagnostic system. The cars they were fitted to may have, for the alarm I believe, and perhaps ABS and SRS, but a 300TDi has no electronics afaik. The first Nanaocom diesel would be the TD5.

EDIT: 300 EDCs were mentioned. I have never seen one. Were they marketed here?
