I see VAP now have a upgrade for the ZF8HP70 transmission. Has anyone installed the tune? If so would you recommend it?

Interesting. I am planning on VAP ECU and pulley in the near future. However, I really like how Jag has tune the automatic transmission. Not sure if I would want it to change. Smooth when cruising and very fast when driving aggressively. I wonder if Stuart from Velocity would comment? Not sure how to tag him but he'll usually weigh in on Velocity threads.

 

Yeah no info here yet, I'd buy it just to enable launch control on a base V6. Also maybe programmable shift speeds?

 

What is coolest about this deal....Is... if you choose that you need the MPV device added, the cost is only $695, but if you say you already have the device and just need the tune...the price is $995 I am thinking they have a coding error ..

Nancy Pelosi must have written this product description. You find out what it does after you buy it.

 

Yep, it would be nice if they told us what it does.
VAP offer great products and unmatched service, but their prices can be a little steep compared to others (I don't mind paying a bit extra for their service and follow up) and their web site leaves a lot to be desired.
And for us mob in Oz the Scuderia Autoart site we are directed to is hopeless, it shows a few parts I am not at all interested in and none of the parts I might be interested in!

 

I also see Paul Busby is offering a tune.

Which raises the question, who cracked it first?
Viezu, VAP or someone else?
And the secondary question, if and how do the tunes differ?
So many questions, so few answers!

 

I’ve figured out how to tune the control module for the MT. It involves a bottle of Single Malt, but unfortunately diminishes shifting performance. I’ll need a lot more bench time before the mod is ready for the market.

 

Given the choice between a great product with a crap web site, or a great web site with a crap product, I know which I'd choose!

 

+1. If you need detail and clarification, it’s simple enough to contact Stuart.

 

hahahahahah

 

My assumption would be that this is just a short term placeholder that they're still working on. I'm sure Stuart will provide a full description once available. Frustrating that you'd require a second tuning device outside of the ECU flash tuner, but I imagine that's due to the integrated TCM design of the ZF 8-speed box.

It'd be very nice if this gearbox tune could improve the launching capability of the vehicle. Launching off idle isn't the most effective way down the 1320.

 

The device MPVI2 is from HPTuners. Some ppl already own the device from tuning other vehicles they may have owned. So, it wouldn’t be fare to charge these clients for a 2nd device..which is why we made it a optional choice to pay for just software or MPVI2+software. The HPTuners device and credits are not cheap, which reflects the price increase when selecting to add MPVI2.

We’ve had numerous amounts of ppl inquire if we could provide a tune for the trans via the HPT device. That product page is for these clients to purchase the product.

We do plan on making a public launch for the product. However, currently we’re not ready to answer all the technical details that would follow. I could tell you the basics like faster shifts, higher redline, increased clamping pressure..but to someone for technically advanced, they would ask how much faster are shifts, would trap speed increase, would 1/4 mile times drop and by how much..etc. We don’t have the research complete to answer those questions. Currently working to rent out our local airport runway for testing.

Stay tuned...

 

Chris, the comment on the device price was not questioning if it should be more expensive with or without the device. The initial version of page had the drop down price logic reversed (i.e. it was cheaper to add in the additional device than it being cheaper to not need the device).

 

indeed a glitch on site..

 

I'm happy to get this for you

Anything to drop into the 10s....

these guys have been tuning the gearboxes on the f type for a while now, £345

What to expect from our Gearbox Tuning:

• Faster Gear Shift Speed
• Torque Limits Raised
• Increased Red Line
• Launch Control
• Faster Responding Gearbox
• Optimised Shift Pattern
• More MPG
• Custom Written Software
• Insurance Backed Guarantee
• 30 Day No Quibble Money Back Guarantee
• Reliable & Safe
• Less Gearbox Clutch Wear

Increased shift response

The shift response has been increased by up to 20% giving a smoother transition, leading to a decrease in unnecessary clutch slippage under full load accelerations, which reduces clutch wear.

With increased shift time you also get an improved paddle-reaction-time by up to 40% in S-mode.

 

8 mph trap speed in the quarter mile is a massive difference. I don't know if that's a truly realistic expectation; questionable claims have always been my issue with Viezu. I've always felt like they fudge numbers to look better.
