here is what is available in USA diesel ECU remapping.
1 low load injection timing.
2 high load injection timing
3 low load injection duration.
4 high load injection duration.
5 low load rail pressure.
6 high load rail pressure.

this is an add on programmer, that plugs in diagnostic port.
it has instruction manual for better understanding of engine needs!

now they do not,as yet, have one for jag diesel, but im sure they would like to.
anyone know if the jag ECU is close to any other vehicle in UK or europe?
Thx Ron

 

Appreciation of your new information Ronbros, keep checking for Jag. diesel specific devices. The engine was originally Peugeot-Citroen, the injection equipment will almost certainly be Bosch, so ECU could be french or Bosch.

After a few thoughts, maybe the injection timing at low load is retarded for sake of NOX emissions? I suggest this because I've noticed this engine is not partic. fuel efficient in this mode. My thinking would be that inj. timing being retarded would result in cooler combustion, therefore less NOX but more soot, (according to classic diesel comustion theory) which is improperly burned fuel. If this soot were burned by more advanced timing, better fuel efficiency would be had.
FYI, in uk as far as I know, NOX emissions are not tested at MOT time, but this could have changed!
We need a set-up software engineer familiar with diesel combustion theory here -- anyone out there?

leeds, im in austin TX ,a capitol of the computor industry, i have talked with a number of computor techs , but they are all about gasoline engines(petrol). not diesel.

they are very good at what they do,(cracking open and hacking auto engine managemnt systems) so they can adjust any part of the maps for gas. all done with a simple laptop computor!

they set the car up on a dyno and retune things until they are satisfied with results.

pretty amazing to see and additonal 30-90 rear wheel hp,on gas cars.

most specialise in hi-performance cars only,its about the money!

on that info i sent,each window has 50 points of adjustment, so it can get quite close on resolution, for smooth but powerful output.

that info is what is available for diesel mostly USA light duty trucks, things are getting better but we dont have many diesel automobiles here.
so to get them to do a program for a Jag,especially if they dont have a vehicle to work with, could be difficult.

Audi is moving up, but the people who own them are not interested YET!

mostly Mercedes, and some BMW, but not enough to make it worthwhile,YET!

and as you are aware NO jag diesels.

THX for your interest Ron

 

as a side note they are going to build an F1 circuit here in Austin tx.

ground has been purchased, started breakin ground. be called "Circuit of the Americas"

all kinds of rumors also.

 

@ Ronbros. My friend from UK suggest to me i should swap out my S-type V8 gas engine for a S-type 2.7D diesel engine. First of all, is this possible and would it be allow here in the US. Does it worth it. I will be getting the engine at little or no cost.

 

Thanks for that Ronbros. As you say, car diesels aren't common in US ATM, therefore high-end problems with fuel control by microprocessor won't be there. As you know, diesel combustion is nothing like petrol combustion so petrol theory won't apply. We'll just have to keep looking.
Re. putting a 2.7D engine in an S-type with a petrol engine, I have done this kind of thing in the past -- we put a Perkins 4.7D straight six in a 1960 Ford Ranch Wagon, and it was then just a mechanical operation -- I wouldn't like to get the ECU from the diesel to work in the petrol car! In any case, you'll be talking a lot of man hours. If your country is one where petrol is faily cheap in comparison to other places (like UK) I'd leave it as it is. BTW, that 2.7D engine is worth heavy money in the right place.

No idea why the system has duplicated my contribution!

It happens to me too , I just recovered it .

 

thanks caddy!!

 

HI, jagspeed,, a little late on response.

yes you could replace your gas engine for a 2.7D jag engine , it also could be a lot of work, you would need the ECU that fits the engine,plus wire harnesses.

exhaust and intake could be fabbed , no prob.

let us know if you plan on it ,or just phissin?

question, where would you get the engine from?

 

A Citroen C8,Peugeot 809,etc if available over there as they have the same engine

 

I wouldn't assume the 2.7D Jaguar engine is exactly the same as the Pegeot-Citroen 2.7D. Jaguar considerably modified it before using, mainly the block of GCI, and the injection system to piezoelectric; but there would no doubt be other changes.
There is of course the economic factor -- overall, for what you spend, will you cover it and more when fuel savings are taken into account? How long will you keep the car? When you sell the car, how much more will you get for it because it's a (rare) diesel? Or are most people predjudiced against diesel cars where you live? There USED to be a lot of that in UK, but not anymore thankfully. Half the cars on the road here are diesels.
Leedsman.
p.s. When modified to diesel, are you going to have problems with regulations (e.g. EPA)? Will it cost more to insure?

 

it sounds as tho the 2.7D or(3.0) LOL, would be a good choice, how available are they in UK or conitnent?

as far as money value, probably never get back what you put into it, its all about the love we have for our unusual cars! espcially a diesel car.

and most people in USA are predjudiced to diesel cars(oddly not light duty diesel trucks),plenty of them,thousands!
but at the cost of fuel, some are changing there minds.

a modded car here abouts can be registered as a specialty vehicle, or just use the vehicle identification number that is on dashboard near windscreen.

just for info, any guess to a cost of a Jag diesel engine with ECU & engine harness, picked up at the location yard?? shipping arranged later!

THX Ron

 

To date in UK, I've not seen a bare 2.7D engine for sale; and I've not seen a wrecked car (insurance write-off) either. Probably a wrecker would be the best avenue of approach, just keep eyes open on www. for something. For a wrecker I would think they'd want around £3000, depending on condition -- in UK there's many rebuilders bidding. Then transport costs, import taxes etc. I'd think you'd not have much change from £5000., say about $8000 at current rates of exchange. I can't help thinking it might be a lot easier to buy a LHD 2.7D in good working order from Europe, and personally import it. Then sell your present vehicle for whatever you can get. Then you only have the cost of meeting your local regulations, plus any faults the car has.
I've a sneaking feeling your BIG problem will be actually acquiring a 2.7D engine. I'd forget about the 3.0D altogether -- they're too new.
