I see a lot of VelocityAP on here but was wondering has anyone done a Viezu tune. Most likely will go with Velocity but was just curious if anyone has used Viezu since it popped up on my YouTube. Thanks in advance!

 

We've seen some talk about the Viezu tuning, but it always seems to be accompanied by an expensive set of add-ons along with the Predator package for the V8. I don't think anyone has waxed poetic yet on a simple Viezu tune.

 

Viezu are Jaguar specialists, so I was attracted to their website despite the fact I have a David Appleby VAP outlet nearby. I was impressed with their professional response and Jaguar background so decided on a remap with them. Oh Lordy! It pulls all the way with no drop-off at higher revs and is so responsive. It's like a different car. What a transformation. Needless to say, I wouldn't hesitate in recommending Viezu. Take a look and make up your own mind.

 

Question for you do they provide some sort of tool where if I need to go back to stock I could or?

 

They gave me a lifetime option to return to stock, or a complete remap if for some reason the update gets overwritten. No tool though, and to be honest, I wouldn't want to do brain surgery on my F Type through the OBD port, so it's back to the HQ or agent. Great service.

 

VAP provides a tool, and its hardly brain surgery to install/remove software. A monkey could do it, really. Just keep in mind, with your anticipated suspension modifications, you won't be able to make the most of that tune. Stock power levels might be too much as it is.

 

You will find VAP more widely used on this forum because they are a forum vendor/sponsor. Having the vendor posting on the forum and providing answers to questions and general support when needed is a great benefit.

 

As I said, make up your own mind. I'm a very happy Viezu customer. With regards to monkeys and brain surgery, tell that to my dealer. When they updated my Intouch Pro software recently (H251,) the whole update froze. The dealer seemed concerned and the software had to be reset and reloaded. I had to have a loaner and return the next day. Glad it wasn't me doing it.

 

Updating the other CANBUS modules is a little different to the ECU tune. As long as you have a battery maintainer hooked up during the update/flash there should be little or no drama. I've done it multiple times and no longer clench buttocks but would certainly advise other module updates be done by the dealer. The ECU flash takes minutes, I've been told by my dealer that a telemetry module update took best part of an hour.

I think there's a geography bias too - VAP being based in Canada, seem to be better placed to support this side of the water. As has been posted before, find someone who can spell (and hopefully pronounce) Jaguar correctly before handing over your money...

 

One red flag for me was the reaction I received from the STP guy who runs the Jaguar F-Type forum on Facebook. I was asking for some advice on the base model vs the S, and casually mentioned that the horsepower difference didn't matter to me, since it was easily rectified with a tune by VelocityAP. I didn't mean to endorse Velocity, or knock STP; it's just the company name that came to mind.. For that, I was booted from the group. The moderator was mightily offended that I dropped his competitor's name, and didn't bother trying to convince in any way that I should consider his product over Velocity's. For me, that arrogance speaks volumes, so unless STP/Viezu turns out to the the Michelangelo of F-Type tuning, I wouldn't give him any business.

 

also known as FType17 on this forum.

 

@supersportmtl is a member here and also has a channel on YouTube, as I'm sure many of you know. I follow him and really value his take on things with the F-Type. I put stock into his opinion and find him to be quite knowledgeable. Anyways the point is, he runs the velocity tune and has nothing but great things to say about the tune (in which he has had for awhile now) and the company. He just bought the crank pulley to and should be doing another video on that this weekend. Looking forward to it!
So with all that said my 2016 R with 6200 ish miles on it (Yes I drive it, bought it second hand 6 months ago) warranty will be up at the end of August. When it is I'm going Velocity. Talked to them over there and I was very impressed with Chris and his customer service and knowledge he gave me.

 

I wouldn't take anything that guy says seriously. He's got his own agenda and isn't afraid to run people over to get what he wants.

 

I have no agenda beyond my own car but have had a great experience with another sponsor of this forum, Racehip GTS Black. It runs like a clock with un-tampered OEM safety monitoring and dynos a little more peak HP with only an upper pulley than Velocity dynos with two pulleys.

That said, peak HP is an absolutely meaningless measure when comparing engine power. What matters is integrating the total area under the useable RPM curve, and two pulleys should generate more overall power. And even using total area integration, the lower RPM area under the curve should probably be weighted heavier since you can't achieve high RPM without spooling through low RPM.

That said Racechip is definitely the way to go for unflagged 10 minute reversabilty enabling low risk warranty work, and also bang for the buck.

 

I respect the fact that he can come here and express his opinions. The reverse isn’t true.

 

Has your dealer ever scanned your to perform diagnostics? It is my understanding the ecm will flag some sort of non-oem calibration. Such as the P167F that a reflash will log. I do like the idea of removable hardware.

 

Yes it has been dealer scanned. I can confirm Racechip leaves no trace. The ECU has no way to know its there because all RC does is intercept and bend two sensor outputs. It's not really right to call it a tune because the OEM tune is not altered.

You can't even really call it a piggyback tune because its more off/on with a few gain levels. The Racechip BT phone app lets you turn it off and control the gain levels while driving, but I have no use for that as I always drive with it full on.

That said, the Velocity tune is nothing like a JB4 piggyback tune either, where you get loads of on-the-fly tunable Maps and individual parameters controlled via a realtime driver interface through the dash with gauge highjacking. E.g you can turn your gas gauge into a boost gauge, or add another psi of boost while driving. Its a bummer we don't have economies of scale to develop something like a $475 JB4 which also leaves no trace as a removable piggyback tune. If any F-Type tuners are reading, it would be great to go in this direction:

The Racechip GTS Black on it's website doesn't list the V8S as a selectable option. It only lists the 488 hp R, 550 hp R, and 575 hp SVR showing 71, 76, & 76 hp gains respectively. Which did you choose for your V8S, and how did you get from 488 (495) to 650?

 

The 488hp R, is referring to the V8S engine.

 

Their website shows the V8 S as an "R 488 HP 5.0 S" ...

Here's my latest dyno, both runs have an upper pulley.


I asked Velocity they use for drivetrain losses and Stuart said 15.6%, so that would make RC plus an SC pulley 662 BHP. It is corrected for STD Day by the dyno itself, but the operator said it would do 10 more HP if the ambient garage temp wasn't 106F.

BHP is stupid though, its all a made up number AFAICT. For context he had a dozen or so Z06s in his dyno history averaging 540 WHP (lighter cars, too).

Also, the +71 HP is max gain, not necessarily peak gain which can be a little decieving but its how all tuners and bolt-ons advertise. My dynos show that to be pretty accurate.
