And also to avoid throwing a code. The boost will exceed anything that the OEM mapping is expecting to see.

 

I thought I already said that.

 

But will it put the ECU in restricted performance / limp home mode?
I don't think it will as long as you take it easy.
When I had the larger pulley installed some 15 months ago I drove home through 60 km of suburban traffic with just the "no pulley" VAP tune on the car (and then I installed the "with pulley" tune as soon as I got home) and the car didn't throw a single code let alone a CEL let alone go into limp mode. But I did take it easy the whole way so I guess you will only have a problem if you sink the slipper!

 

According to Stuart if you run the big pulley with the stock tune and beat on the car it will throw CEL codes for too much boost. I asked the question of him about this issue before installing the bigger pulley. I was concerned about dealer visits with the pulley tune on the car. He said you could revert back to the stock tune with the pulley before a dealer visit but to take it easy driving to/from the dealer.

 

Maybe I was not clear. My question was will the VAP no-pulley tune VAP tune not stock) work well with the pulley or does it need a new special big pulley tune. And would that be for all 3.0 SC cars?

 

Put simply, no.
Longer answer - the no pulley VAP tune caters for some increased boost but nowhere near as big an increase as the "with pulley" tune, so as I and others have already said the no pulley tune will "work" with the larger pulley but it will not work well, you will not get the benefit of the larger pulley (more boost = more torque and more power especially under the line) and you will get CELs and limp home mode if you drive it hard.
Same for all 3.0 SC Jags.

 

It won’t put it into limp mode, but will only throw a code if you push it past 5000rpm under power.

 

Doh!

 

I have been running the Velocity tune for over a year with nice increase in torque & hp. If I decide to install the crank pulley would I need to re-tune the ecu?

 

Yes to accommodate/take advantage of the extra boost.

 

I suspect if you buy VAP’s pulley, they’ll throw in the tune upgrade for free since you already have the download device.

 

My understanding is that Unhinged is correct. In general, I understand that once you've bought the tune product, if you add hardware later you get updates on tunes no charge (I'm assuming within reason).

 

When I bought the tune only a couple years ago they sent me three mod files, a tune only, a tune for 200 cell cats, and a tune for a crank pulley.

 

If you purchase our pulley from us, or one of our authorized dealers, there is no charge to update the tune for a crank pulley.

 

I've read through the entire 40pages of this thread. Very interesting. For those that have had the tune/pulley upgrade, after 2-3 years, have you had any issues?
I've had a tune for almost a year and ultimately no issues, I wanted to purcahae a pulley, but have some concerns about the added stress over the long term.
I have an F-Pace, any thoughts from those with a 3.L V6?

 

I asked this question of VAP Tuning Support when I first got the tune. I had asked for 91AKI and 96AKI tunes, in case I wanted to track it (Sonoma has 96 at the pump), plus lower pulley versions. The answer I got was "By default I add in the allowance for more charged pressure even on vehicles with no pulley added so that pressure is not spiked and limited, also this way the vehicle will not need to be flashed if a pulley is every added."

Note that this reply was specific to the tunes I requested at the time I requested them and may or may not apply to other tunes out there.

 

4 years, 27+k miles on the tune/pulley, always push it hard (avg mpg<15). No issues: I have the oil tested at every change ( 5-8k mile intervals) with zero indication of excessive wear.

 

Almost three years and 25K miles with my tune (no pulley yet), and I too get my oil tested regularly. I just got my latest report back (need to put it up in the appropriate thread) and wear metals are looking great. I don't always push hard because I commute in it, but I push hard when I can. Lifetime fuel economy is 18.7, and I also monitor that carefully as yet another indicator of mechanical health. The tune had no appreciable effect on average mileage, although if *all* my driving were of an unhinged nature, that would probably not be the case.

 

Steve and Lance, what would you do if your oil tests revealed excessive wear or some other indicator of ill engine health? Just curious as I don't push mine that hard and have no expectation of ever having an oil test performed.

 

Six months with tune only then 18 months with pulley and tune and zero problems.
But I change the engine oil and filter every six months, not because of any added stress caused by the pulley & tune, but because 75% of my trips are very short (1 or 2 miles) and the engine doesn't even get warm.
Get the pulley & tune, you will love it!
