I’m looking at just a tune for my 17xe. I don’t feel like pushing the motor to its full potential and wearing it out quicker. Wondering if anyone has done just the Velocity AP 1000$ tune for 416BHP and 353Trq. Any gripes or have you had transmission issues? I have awd.

 

The Jag AJ126 in the XE(340h/380h) is identical to the F-type S(450h) minus some very very minor differences. I'm not going to open Pandoras box for debate on variable oil pressure delivery systems....

The comment of wearing it out sooner is not really a situation with this power plant as it is already at 450h in the F-type S.

The AWD system in the XE does leach power; and noticeably slower than the RWD model. But due to the grip the AWD has, its no drama launching. IMHO the base tune and no pulley on a AWD is same as a standard RWD.

With a lil' poking around you'll find the XE AWD has the zf8hp70. The trans is rated almost double what the power plant puts out OEM. Lol. Trans is surely not the weak link.

Change your coolant passages. That's the weak spot.

 

The V6 in the F-Type is identical to that in the XE, it is not 450 hp stock!
It is either 340 PS in the base model or 380 PS in the S and later the R-Dynamic with the only other variant being the 400 Sport with surprise surprise 400 PS (1 or 2 years only, I'm guessing 2018/2019?).
450 hp is what the V6 puts out with a larger lower/crank pulley and ECU tune such as from VAP, which is what I have in my F-Type.
I have had that set-up for some six years now with zero engine or trans problems and so have many others here on this forum, it is a very safe state of tune.
Before that I had the VAP "tune only" in question, again perfectly safe and reliable, but it just wasn't enough for my liking so I spent a little more and got the crank pulley + tune upgrade.

 

I actually did that this weekend! And it went phenomenally. No issues and it really wasn’t too hard. Though I’m a ford mechanic so I’ve got the knowledge slightly already

 

I’ve run the VAP tune only for a number of years on the F-type. Since I started at 380HP, 416HP is not a big jump. Some of that comes from a slightly increased red line, which I never hit.

Some day, I’ll do the crank pulley.

 

I have a an XE S with 380 hp, is it not worth it to just do the ECU tune?

 

Do you need to hook up the car to a battery tender during the flashing process?

 

Yes, to play safe.
Many recommend a high power unit, 30 or 40 amps minimum, rather than a garden variety low amp tender such as a CTEK.
However the three or four times I have flashed my car I used a 15 amp tender and have never had a problem.
But I made sure the tender had finished fully charging the battery and was in maintain mode before commencing the flashing process.

 

No need for a tender,just drive the car for 15mins done it alot of times with no issues, do not hook anything to the battery,
