I am happy with my stock 340Hp/450Nm map and I haven't had the car long enough to think it's lacking power. Coming from a tuned turbo charged FWD, I'm enjoying the progressive and constant speed development of my first supercharged car. In my previous vehicle, the power increase was nice but it came at the expense of reliability and stability but it was a 2008 car and reasonably cheap to maintain compared to the F-type. I wonder what the extra torque and HP do to a daily, all year round base model in terms ride quality and reliability...

The natural power output of the V6 seems to be around 400 horses and a good remap will arguably do nothing to reliability. Before the F-Type I had an XF with the AJ126, remapped it from the stock 340 to about 415 hp and ran it like that for some three years with zero issues. Mind you if you remap an AJ126 you usually just get a small torque increase and a power bump towards the top end of the rev range so there won't be a big difference in everyday low rev driving. Replacing a pulley or two seems to be what makes the biggest difference.

Very helpful, thank you! Did you map yours?

Nope, haven't remapped mine. I have my local trusted remapper who already did a BMW and two Jags for me in the past, but I never intended to remap this one. I think the RWD V6S already has a bit too much power and I have zero interest in any more straight line performance in an F-Type. It's also already so close to its natural capacity so a remap would basically only add a bit more torque throughout and some 10% more power high in the rev range. Recently I have however played with the thought of remapping it after all, but mainly to get rid of or reduce the pops and bangs and to just let loose those last horses which are just unnecessarily down tuned to make sure it runs well on dodgy fuel in far away countries or whatever the reason is.

I'd definitely remap a 340 hp car like I did with my last one, because I think it's just silly that they down tune them so much and some 75 horses makes a bit more of a difference. And there's loads and loads of remapped AJ126s out there running without issues so a proper remap to no more than around 415 hp is a safe bet reliability wise.
 

Yeah, I've only just started exploring more of the car's limits now that the weather is finally decent. It's been a long 5-month wait for warm temperatures and fully dry roads. I still think the straight line acceleration is quite brutal and being a manual RWD makes me wonder if it needs any more power.

I'll probably dyno it first before remapping it to ensure it's not mapped already and then decide. But I'm in no rush as it's plenty of fun as it is.

Ah, the old "needs versus wants" conundrum! :lol:

Yes it's definitely best with a dyno. I've had all my remaps done with pre/post dyno runs.

Apologies I am new here ,my F-Type was so economical I was very surprised also my rev counter was sitting just above Idol , I've since been re living my youth going to Blackpool just for a Chippy supper because In many years gone past we would all chip In for petrol and go a drive In my Mark 2 Mexico mileage again was astonishing but I can't give a true reflection as I used cruise control one way and my foot the other , what i did notice there was a difference In economy using cruise control rather than doing It myself but I would recommend the Upgrade without a hesitation on long drives it just sits purring along l and they have just released the Predator Mark 2 pushing 1000BHP after 20 odd years I've never had a problem with any of them and all have been re mapped they they are bomb proof but by far the 5 litre power plant Is truly remarkable, I'm now going to part with my F-Pace and get a XJ back I really miss those cars.

wow you really do like Jaguars! The Predator package looks amazing but too much money for me sadly, i'm after the tune, exhaust and the new air intake they have coming

Did it bump up your insurance much?
Click to expand...

Thanks ,,yes I took a hit on the Insurance but I was prepared for that and had It factored Into my budget the exhaust sounds amazing Jaguar spoiled them years ago by adding a software update to the R's In particular to tone the noise down and unless you knew about It and told them not to do It they would do It as part off the service but the Viezu one will leave you with a huge grin I promise the old stock one before the software debacle sounded like a Spitfire It now sounds like a Lancaster bomber best exhaust I've come across with the option to turn it off and have It sound as It was meant to I honestly believe that the 5 litre power plant Is the engine I've had the pleasure off owning anywhere you take them they draw so much attention I've also just added 20 millimeter spacers to the four corners bringing the tyres flush with the bodywork and I can truthfully say It feels more planted (save hard and get the full package)
 
“I wonder what the extra torque and HP do to a daily, all year round base model in terms ride quality and reliability...“

I can assure you that a 340, with its artificially limited headroom, is crying out for a tune.

Mine went from 335 to 401bhp with no noticeable hit on consumption and really comes alive for a very modest cost outlay.

Definitely worth doing pre and post dyno runs too, so you know your base point and can see a very safe AFR afterwards too.

I’d say that it’s the sweet spot for RWD drive ability and that for responsible road use the reliable open diff is just fine.

If you keep the tune to no more than 20% you can find very decent insurance quotes if you dig around out there.

they have just released the Predator Mark 2 pushing 1000BHP after 20 odd years I've never had a problem with any of them and all have been re mapped they they are bomb proof but by far the 5 litre power plant Is truly remarkable, I'm now going to part with my F-Pace and get a XJ back I really miss those cars.

I believe the Predator 2 is about 750bhp and 1030 nm torque as they had one at Supercharged Saturday just gone.
 
I am proud owner of P450 for little over 6 month now. I am thinking of getting a Viezu remap done to my car. I live in Germany and the regulations with TÜV (same a MOT in GB) are super strict. They will check your car for the software on the ECU using the CVN (Calibration Verification Number). Is this is not correct, then you will get your vehicle impounded and need to buy a new ECU from the dealer...
Could someone with a Viezu tune (preferably on a P450) check with a OBD scanner for the CVN? A good app to use would be Car Scanner.
At time of writing this I´m really questioning my decision to make a tune on the car...just crazy what is going on in Germany...

Thanks very much in advance.
 
Might also be worth asking Viezu directly (they are normally very quick at replying) and also asking them whether flashing the ECU back to stock will let the CVN flag the correct response, because you could then buy one of their MyGenius home flashing tools and do that yourself at leisure.
 
must not read this thread anymore!

must not spend more money on the car!

but i do need a new exhaust, i would probably have to get a tune too, just to make sure the exhaust was running properly.

and you might as well get the air intake too!
