Your really missing out if you don't install the lower pulley!
So easy it's not even funny! I mean in 45 minutes I installed the lower pulley and the VAP tune.

The upper pulley will give a little more but your now in declining returns so far less HP per $.

To be fair to Viezu they phoned me today because they realised they missed out the word pulley to confirm they meant “modifications such as a supercharger pulley” not the supercharger itself and wanted to clear up the confusion.

Also walked me through the process of how it works with regard to reloading the original file should i need to and how it works on the unit, so I’m all good to give it a go this weekend, my confidence has been restored.

Will report back how i get on.

 

The engines fundamentally are all the same - in any meaningful ways anyway. So we have tuning for the 2014-on 5.0 Supercharged engines, which includes the P450. It's just a detuned version of the same engines that have been fitted since 2018. 605BHP on good quality pump fuels, just the tune - you would just select 'no' for the pulley options. $995, including flashing tool. https://www.velocityap.com/product/j...-fpace-svr-xj-

 

They have numerous videos specifically on the F Type R sports car. It's obvious, they know their stuff.

 

Disappointed that Viezu's post appears to have been removed, I thought it offered a good explanation of their offering, but I guess it must have contravened a forum rule of some form.

Anyway, by way of an update, after they'd called on Friday, explained everything and restored my confidence that I'd got the right map on my unit, I found the time on Saturday to load the map which took about 10 mins. The menu on the MyGenius changes after you've done it and it gives you the option of "ORIGINAL" or "MODIFIED" so you can put it back to standard. That menu wasn't there before I'd written the modified map to the car for the first time, so it updates the unit once it knows you've installed the file, this was my original angst with the file they'd sent me as at that point I couldn't see the menu with ORIGINAL in it.... all sorted now.

Had a chance to go for a drive with it today. It's actually insane that the P450 is hiding all this extra performance in stock form with no other mods needed. When I first got the P450 I thought it was pretty obviously being torque limited, but not slow by any stretch. It was seeing that torque limiting shown on the rolling road graph on Viezu's blog - https://viezu.com/blog/jaguar-f-type...and-remapping/ that made me buy this map/upgrade. I want to stay mechanically standard for the time being, and this seemed like a great thing to do.

With the new map it is so much more urgent without the artificial limits of the P450 map being applied, only had a quick squirt up and down some local A roads but already think as a road car, I almost think it doesn't need anything more in the power department, I'd probably want beefier brakes and handling mods before increasing it any more.

If you're on the fence about this type of upgrade from Viezu/VAP and you've got a P450 I can 100% recommend it for the performance bump it offers for modest spend, you will not be disappointed.

 

You know regardless of you putting the oem map back on, that if the dealership wants to they can find that the ecu has been played around with.
If any mapping company tells you otherwise they are lying.

 

Yes I have found this to be true with an aftermarket scanner and SDD will also record it as well.
Here is what I found:
Non-OEM Tune Code

Now I did have a claim by someone that they could delete that but never any facts just claims?
So maybe someone with enough knowledge could do something to the CCF? Just a wild guess?

I don’t think anyone has claimed it to be undetectable. Every car I’ve ever had mapped has set flags in the ecu to say it had been written to.

 

some tools like cmd flash or some softs or tuners can remove the fault of moded file when flashing the car

 

Working w/Viezu was a great experience. Excellent product and communication. I had the pulleys installed w/no issues. Installer used to work for Graham Rahal Jr and said that the product was very easy to work with. Xk dynamic r came back at 645 hp . For an old guy, it's a freaking monster. Highly recommend the company and the 650 hp program. I absolutely love my car.

 

It's cold, there's salt on the road, so let's play...
I'm seriously considering increasing the power of my RWD V6 with 340 hp, year 2017. I've had the car for a short time and it has only 54 thousand km. I admit that the promised increase in power from 340 to +/- 400 hp will be more than enough for my standard brakes, open differential and very little experience with a powerful car. Viezu is the closest to me from a geographical point of view and compared to VAP it is also much cheaper. (I'm not a dealer or paid for advertising!) On the Viezu chat, their colleagues solve my tricky questions willingly and immediately. This is very important to me... I'm not IT and I may need remote assistance during the installation. So far, I have read from the communication that it would be the following change: More power/torque, slightly higher fuel consumption N95 or N98-100oct. (I don't know how much?) and the cancellation of the maximum speed limiter. I'm planning another trip to Germany and there I'll drive legally at whatever speed the car or my fear will allow me to. Since I'm the second owner, I don't know if someone has already remapped before me.... It seems to me that the car is going really, really fast..! When asked "if after buying the Viezu package I find out that the car has already been remapped in the past", I understood the answer to be that I'm unlucky...and no one will refund my money. But I can understand that. I don't know anyone in the area who I would entrust my car to for diagnostics to find out what its real performance is. I tried it myself and didn't find anything using IcarSoft-JLR or Dashcommand. Any ideas on how to find out if the car has already been remapped please? Thanks for any ideas....

 

I have just done what you want to do on my MY2014 F-type v6 340.

it is very easy. The communicate great.

I still have to make some kilometers and I don’t know every detail of what to expect. But it feels great and not rediculous. The power is more in the higher revs.

you can do it!

regards,

Adam

 

+1 Mapped mine a few months ago with Viezu and it's very straightforward. They can send you a video explaining the process. It takes about 30 minutes to read your car's map and store it on the MyGenius device so make sure the battery is charged and working well or connected the car to a trickle charger.

You then email the file and they will return a mapped version which you can then load onto MyGenius and transfer it to the car. This second part of the process takes 5 minutes.

I had the car for 2 years before deciding to tune it. I loved it before and even more so now. Mine is a base model, manual transmission. The power delivery now is more linear and feels amazing.

With more power you'll need more frequent oil changes and ensure that your coolant system is working properly. I upgraded the pipework to JLR alloys including the water pump before tuning the car. So that'd be my advice in any case.

 

I agree about the supercharger small pulley change, not such an easy process to do properly. However the bigger crank pulley change should be the first step together with a new personalized tune uploaded to the car. I did this work myself on my 3.0l V6 using VelocityAP’s

package and am very pleased with results and increase in torque. I think Viezu offers a similar package.

 

The lower pulley is certainly a much bigger benefit. I did mine in the driveway. I can't remember if I used ramps or stands, but probably the former. Here's a picture of everything I used for the swap. I did it in half a day, taking my time. It'd be considerably faster if I were to do it again.

 

Hi. I've been having new questions about Vieza, but since they haven't responded to my last two messages, I'd rather wait to make a purchase. Maybe there's a glitch in the communication system? Has anyone had a similar experience with them?Thanks for the response

 

Must be something else, they communicate very proptly, in my case.

 

Your tool budget is higher than my tool budget.

 

Most of those are from the '80s, when fixing Saabs was my livelihood. I kept all my hand tools when we closed down the shop 34 years ago. The Torx bits came much later; either for the Jaguar or its predecessor, a Volvo C30.

Just last weekend I was commenting on how glad I was to have acquired quality tools back then.

 

Thanks to everyone for the responses. Viezu contacted me about my message shortly after I published my post here on the forum. But the deal didn't go through anyway!
The advertised price on the Viezu website is not valid. The subsequent price quote in the email was much more expensive. According to the Viezu assistant, the prices on the website only apply to work done directly at their company. However, this is not clearly stated anywhere in the e-shop! So I didn't complete the purchase. I'm disappointed with the deal. Sure, just my subjective feeling, which comes from a possible misunderstanding. I'll try again in a while. But I'm writing it here just to be sure, in case someone else believes that the prices on their website apply to everyone... No. They don't!
