The LS and many Fords have a PTEC or Power PC based ECU. I have several tunes if you are interested. The code on the PCM must be known to properly program it.

Tons of stuff on the web about the SCT. They have several versions including a pro version. This is what the tuners use to burn a tune.

I have attached one of my tunes if you want to look. I don't know how you would open it without the SCT software?? It is zipped to get it uploaded. From the file name you can tell it is for a PCM with a HJC1 code.

Thanks. I don't know, either, but will at least try!

When the S-Type got the 4.2 did the LS not get it? How abot the T'bird? (I'm thinking DEW98 but any others relevant?)

I wonder which PCM is in the new, high performance Fords? Do I mean 5.0 Mustang? (I confess to ignorance about them!)

 

Tell me more, please. Which PCM (ECM) did it start/end with? Whose tune & which tuning device? Which Eclipse should I be reading a bit about on the net (it's a bit of a common word and google finds rather too many)? Is it even an OBD II car?

 

There are tuners for Denso. Subaru (WRX STI etc) and Mitsubishi (Evo 9, X, etc) use a different - I think quite a bit simpler - Denso.

edit: Denso apparently also used by Nissan (350Z etc) and Mazda (MX-5, RX-8)

Various Toyota & I think Honda cars use Densos but I never heard about them being tuned (my ignorance).

Anyone have such a car? Especially an Evo or Scooby (Subaru)?

click through to the STR and you find:

(I never heard of them before stumbling on this.)

 

No the LS never got the upgraded 4.2L. Lincoln did a 2003 upgrade that added a less complicated VVT system plus a better style of timing chain with finer teeth, mainly for lower noise. Known as a Shubuta (spelling??)chain after it's Japanese maker. Jaguar did not upgrade the chain. The Tbird is exactly the same as the LS.

The Jaguar had VVT from the beginning. The Lincoln version can only vary the intake valve timing is 3 separate steps. The Jaguar system can adjust continuously over the range. This is for the V-8 versions only. The V-6's were a little different.

Of course both of these system still are only affecting the intake valves. The better systems are like the BMW Vanos. It not only changes the intake but also the exhaust valve timing and is continuous over a wide range.

Finally some systems add the ability to vary the valve lift. Probably the best known of these types is the Porsche VarioCam Plus. But even these are still limited. Most are only a two step system like the Honda VTEC.

Probably the ultimate at least with a poppet valve type engine is the air spring style. Individual valves are controlled by air bellows directly under computer control. Sometimes also called a cam-less engine. This gives complete and independent control of each valve regardless if it's an intake or exhaust or a 2,3,4 or 5 valve engine. Not really available yet but engines have been built and operated so it is possible.

Looks like the complexity and ever tighter emissions laws are driving makers to ever higher-tech engines and PCMs. PTEC looks to be barely powerful enough at "just" a twin-CPU PPC. Densos look to be single-CPU (Evo, Scooby etc) or twin-CPU (jags) where each is 32-bit Renesas SuperH family.

I wonder what's in the ZF's TCM! Anyone got a spare/scrap one?

edit: SCT apparently have ZF tuning at least on some Fords http://www.fordforums.com.au/showthread.php?t=11338701

 

I'm very interested but it appears you have to ship both your pcm and tcm to Australia...I own a Jag, I don't know why I don't own a second vehicle...

 

But aren't SCT a US firm?

(What I posted is from an Oz forum.)

 

No idea...I emailed the guy, I'll keep everyone informed...

 

Seems a bit less than optimal (ahem) to email an Oz firm about a US firm's tuning LOL

They have US dealers

However, SCT may need direct approach to think "jag" as it won't have been their first choice.

 

lol...Good point; jokes on them though, I had really low expectations to begin with...

 

In my short quest to find someone who might be able to tune our cars, I first looked locally. Dynocomp has a so so reputation in AZ, but nonetheless a lot of people use them. Their prices are outrageous.

As you can see below, they claim relatively decent gains but not for the money. I haven't given them a call, but if they can tune a rover perhaps they can tune our jags? I am not sure what the computer situation is from jag to rover but at least the SC'd AJV8 is right?

EcuFlash is what I've met for Evos & Subarus. I've been wondering if it might work.

 

The Stype had 2 main ECU versions, one until 2006 (32 Bit Denso), and from 2006 the Denso PanPag. The latter is used in the RR, and might be easier to tune as there are more toosl on the market that can read/write to the ECU itself.

For info, here are the stock ECU files for the 32Bit denso and ZF 6HP26, please note these are for the Stypes from 2002.5 until 2004 USA market VIN M44998-M96300:

You could send it off to a tuner first to see if they understand the programming as it is no point sending your car if they don’t. But it isn’t easy, you need to have some good background already, and it might take some trial and error before you will find what to change that will work.

 

Thanks.

Should be able to reflash using Jag's J2534 software for J2534 tools and any of the compatible J2534 tools - e.g. CarDaq from Drew Technologies. The tools are $500+.

The jag software has a load of smarts specific to their cars and the J2534 tool has the electronics. You provide a PC with Windows and your car. And a battery charger or the like because a failure during reflash is not funny!

You need a short term subscription to jag's TOPIx to get such as calibration files.

As I say, what's needed now is a way to edit maps etc inside the PCM software (calibration) files. TCM, too, if you wish, but I don't know if the J2534 does TCM or not (never looked).

The above way of doing things is mandated by law for essentially all car makes sold in USA.

The only thing I'd want to know from a tuner would be whether they can edit the maps etc - and preferably on the dyno or next to it. Anyone half-way into tuning should be able to do the reflashing as above. Run if they can't.

I really must get hold of a TCM and later-model (Denso PanPag) PCM
Been looking for an old WDS but so far too expensive.

 

He replied, says he can't work on Jags...Shocker...

 

He probably doesn't even know!

It's the file editor I feel is the central issue. Reflashing is solved.

 

hmm, now those files are odd! I have the March 2010 files (from jag's GTR) which have slightly older ZF versions (July 2003 rather than November 2003). You'd think by March 2010 they'd have a consistent set!!

 

Sorry it's taken me so long to see this post. The tuning was performed at Koppel Mitsubishi on Northern Boulevard in Queens New York. The tuner's alias is Randy Mitchell aka (Koppel) who's now out west at the dealerships there. He was just a spoiled rich kid with deep pockets that enjoyed souping cars up. As an example, he had a 3000GT that he'd worked up and this eclipse would absolutely kill it to 60mph. I killed vipers, modified mustangs with the 380's and spray in them, I owned all of the turbo boys including the twin turbo rx7's (at that time, I hadn't run into a Supra that was fast enough to take me out, though I've seen a few recently that are just rediculous... Not just in the quarter, but in long stretches too. I also killed several of his M3's of that era that were heavily modified.

I can tell you what I purchased at wholesale (Turbo @ 30+lbs of boost pressure 3k, HKS Stainless Steel exhaust 7" diameter and all associated gaskets/fittings 900.00, Laptop for the Glove compartment (electronic boost control) 1k, Larger intercoolers 1.1k, Grety Blow Off Valve, down pipe and Aluminum Heads. (I have an invoice with the MFR for all of the parts but that's in NY. I'll look for it when I go back this weekend). I gave him and his crew about 3k for their pockets just because they liked playing with cars. I don't recall what if anything was done to the ecu, though I'm sure something

The work was performed in June of 1995, so the pricing is based on scale at that time.
