any truth to brief commentary that this tune neuters the crackle on overrun?
can hear a definite lack of burble in this video

we first loaded the tune to match the lower pulley, I did note a reduction in overrun sound, but VAP adjusted the tune to resolve that issue. I would presume that they have incorporated that fix into subsequent tunes they send out.

Hi Everyone,
Haven't updated this thread much lately. Have another dyno sheet here for you. This was from a customer of mine in Austin, Texas. Wonderful guy and long time customer (he has an Aston we've done lots of stuff with.)
This graph shows the before & after on the supercharger upper pulley & tune as a combination. Nice 52WHP and 47WTQ. Backs up pretty nicely as the the testing work we did on the tune alone showed 42WHP gain, so another 10WHP picked up from the pulley.
Solid gains throughout the RPM Range of both torque & HP. Worth noting, we actually sent the tune to him much earlier in 2016 and have since made a couple of little improvements. I did send the updated software but they didn't realize when they ran it on the dyno. I'm estimating that there's another 3-4WHP in new tune.

Maybe 15 at the crank is a good expectation. The crank pulley makes more for certain.

Hello, quick question...
I just got an F type R and I'm looking into your tuning platform. I noticed on your web site that the dyno graph image for the after dyno shows a max AFR of 20 on the bottom. When in the process of the dyno run was the AFR at 20?
I'm not super knowledgeable on this stuff but 20 seems really lean especially for a supercharged platform.

From memory we were running about 11.5:1 on the datalogs. Chris would know for sure. Either way, it's not super-lean or anything. We like to keep some safety margin in there for forced induction setups.

The dyno graph on our site has torque values on the LHS Axis, and HP Values on the RHS Axis. The AFR graph is plotted on there just to show what it looks like, but it doesn't correspond to the values on either of the Axes.

It was probably just some anomaly during a lift off or idle or something but I was just curious.

What dyno graph are you guys looking at?

Jaguar F-Type R 5.0 Supercharged ECU Tune
Image #6 at the bottom.
I went ahead and ordered the tune. But I'm going to get a kiwi 3 and a phone app to monitor things pre and post tune to see what the ratios are.

Yes, it probably went to 20:1 or something like that on lift-off. Looks like the dyno didn't stop recording right away. On lift-off the AFR on most vehicles will go well above Stoichiometric (14.7:1) because it's not injecting any fuel to speak of when you lift off.
Under load, it won't go much past 11.5:1

Ah... I think I just figured out - you are looking at the numbers below the graph.
