Fairly new owner of a low mileage unmodded (except for P4S's) 2015 V8-S Conv. I've done a tone of forum searching and found some old threads where Cambo is talking about successfully flashing the ECU on V8S's with the V8R tune and having some amazing results. It also seems that this is the only way to do a tune that doesn't leave an unremovable fingerprint of a tuned ECU, also I would feel better running a tune made by Jaguar vs 3rd party. From context it seems like Cambo is part of a shop in Australia?

Any options for someone wanting to get this done in the US (Georgia)? Assuming it has to be done at a shop with a special computer.

 

This would not be the case. (In Red)

1.) When you flash the ECU, it will show another count of being written to in most cases, regardless of the source or file.
2.) Assuming (the only reason I could imagine) you are not wanting it detected is for JLR not to know you tuned it...It will be obvious to any JLR entity that you have the wrong file in the car. Your Vin (and badging) will indicate V8S, and the tune file will be for an R

I would imagine with a 2015, you are way out of warranty. And the VAP tune is in many cars, tested extensively (by them, and all of the customers running it over a long period of time), and has performed flawlessly.

Also, if you have the wrong (R) file in your car, and you go to a dealer and they apply any update for the (S), who knows how jacked up that will be...

Thanks for the quick response. You're right that I'm out of warranty and planning to service the car in the future at an independent shop (haven't located one yet). I'm also not planning to hide any ECU tuning from future buyers but I do think I'd feel better explaining to most buyers that the car has the factory Jaguar R tune.

For context on what peaked my interest most about this and gave me the info was Cambo's below post "I have a file which is a modified F-Type R tune that can be flashed into a V8S using the SDD. Have put it in several cars now. The ones that had never been touched, no P167F-00 code is tripped. But the car that had previously been flashed using a KessV2 would keep popping up the P167F-00 every time, even after putting the stock/factory V8S tune back in with SDD, clearing codes, hard resets, forced resets, nothing will get rid of it..."

Unless you somehow manage to get a hold of dealer's tool, which you won't be able to, and use that to change car configuration, any tune you apply will trip 'this car was tuned' flags regardless of the actual tune file used. So V8R stock tune will be flagged the same way as any other tune.

 

Maybe, just maybe, you could buy V8R ECU and have it coded to your car and have dealer convinced to 'forget' to reset it to V8S. It just an idea, don't think anyone tried.

 

I'm assuming that's what the SDD tool that Cambo is referencing, is that not something that an independent shop would also have?
Can't believe this isn't a more common topic with V8S owners with this seemingly being the only power difference between the V8S and V8R.

 

Well the VAP tune and pulley work very well and are super easy to install compared to fighting thru the SDD. I mean like an hour or so total if doing the lower pulley and tune.
No most aftermarket shops will NOT have SDD. It is NOT released for public use and Jaguar has no interest in helping anyone use it either. Plus now it's obsolete as Jaguar has moved on to Pathfinder.

All of us that are using SDD have to rely on each other and lots of second hand information to get it to work. Plus the added cost of the special cable required and a dedicated laptop to run it.
I just found the VAP setup way easy to use and install. I have a fully working and up to date SDD setup also as it really is the best repair software out there for Jaguar's.

Yes that is what Cambo is using and talking about.

SDD is the JLR OEM system. FWIW, why flash the 'R' file when you can flash the SVR file? There's no difference in the engines.

 

if that’s true then I would agree! I thought the SVR had additional cooling or something?

 

Or we can get you 605

 

I thought I heard my name!

The calibration file in question was a 2015MY Euro2 F-Type R file, it was altered to allow it to be flashed to any 2014MY V8S, without tripping the P167F, using the SDD tool.

This was the one and only. It's not possible to load the original SVR or Project 7 factory files to a 2014MY or 2015MY using SDD, there are many differences in the calibration file from 2016MY.

Unless you really want to avoid the P167F code, there's no real benefit to this. It certainly won't be cheaper than a commercially available tune, given the time & effort involved to make it happen from the other side of the world.

So as much as i'd love to help, there are going to be easier options for you...

In the meantime, 679hp is the benchmark for tune only, no pulley

 

You can actually.

An independent specialists should have SDD. However it is unlikely they will know how to flash something other than what is stock.

Again, an independent specialist should have SDD. SDD is not obsolete. Pathfinder is only used on 2017+ vehicles.

 

Good luck finding a shop with SDD and people that know how to use it. Correct SDD is obsolete and Pathfinder has taken it's place.

Incorrect.

 

Looks like we have ourselves a new expert. Instead of condescending one liners, why don't you enlighten us with your vast knowledge?? Sounds like Cambo (who I think is very knowledgeable) and everyone else on here is wrong,. So school us...

How about a step by step instruction set on what is needed and how it can be done, including some specifics (instead of "incorrect" etc.?

 

If you read the thread carefully you will see that Cambo was talking about firmware flashing, compatibility and DTCs. I am simply correcting misinformation about the usage and obsoleteness of dealership diagnostics software. SinF states that you cannot get hold of dealership tools, well, you can. clubairth1 has stated that SDD is obsolete when it isn't, it is still used in dealerships to this day. He also states that Pathfinder has taken over from SDD, which again, isn't the case. As I have already explained, Pathfinder is for 2017+ vehicles. SDD is for (some) vehicles up to 2017. They both use different ways of communicating to their associated car ranges. Which also requires a change in the physical interface.

The one liner was because I had already replied to him before with the correct information to which still said "Correct SDD is obsolete and Pathfinder has taken it's place."

I won't go back and forth with on this as it would serve no purpose. You've said your piece and I've said mine. Instead I'll try to help out with the OP's initial question.

My suggestion would be to find an independent specialist who has SDD AND who would be willing to allow a third party to logon remotely and make the necessary adjustments to allow the firmware flash as it's not so simple. It requires essentially tricking SDD into believing your ECU/PCM is already that of an R and applying the update. Your average local specialist probably wouldn't know how to do this or may end up bricking the module. The actual hardest part of this whole thing is finding one party that is willing to work with another party and visa versa as this would be done remotely likely from a different country/continent so would have factors like trust and liability involved.

That being said there are also specialists out there that can flash the factory firmware WITHOUT the need for SDD and still it still wouldn't flag the DTC. But I would say that this is probably an even harder avenue to go down.

Hopefully you get somewhere with this

 

Its not in warranty, vap are a recommended and renowned tuner with 1000's of tunes and happy customers.
It will literally take an hour or so to tune your car where as our "new" expert has said it wont be easy doing it the sdd way and you'll
only get 542hp not 605
No brainer really
