Hi Folks,

I'll see if my friend and I can trade cars again ... I'm curious to feel the map 4 setting on the Juicebox. I want to make sure I have that point covered.

But from both the Vishnu and Burger websites, it would seem that both products will auto-tune for the modifications in the car.

I won't have time to do this tonight, but perhaps tomorrow evening and will update accordingly.

Thanks for everyone's comments!!

I don't believe any actual "auto tuning" is going on, regardless of what vendors say. At least not from the side of the tuning device (PROcede, jb3 or whatever). The only active compensation mechanism is adapatation from the DME. Although "auto-tuning" sounds impressive

I wonder how much your lack of a DCI matters. Does this mod make much of a difference in everyday driving? I would think it would help since you are running a tune.

David_12 - I'll see if I can get some cones on my car to make more of an apples-to-apples comparison (or get my friend to go back to a stock airbox ... not likely).

Shiv - thanks for the clarification on the "auto-tune". Essentially, the stock ECU will deal with feedback it sees (through the piggybacks) with the modifications in place.

If you believe the dyno numbers from vendors who don't sell 'these things' it's likely the "lack" is zero.

After a whole weekend testing toones I came to the same conclusion. PROCede really maintains the BMW refinement, and don't let the smoothness fool you into thinking its slower, its not.

Check that box baby! Scan V3 reciept$ or ban! j/k.



Good job, thanks for sharing.

Shiv could end up at the top of the heap of the piggyback tuners since his main competition talks like he's anticipating abandoning his piggyback in favor of a flash.

Map 4 is going to feel smoother than map 6, especially with 91 octane.

Map 6 has a slightly more aggressive boost target that starts a little lower in the powerband.

Map 4 power will start a little later in the powerband, but will still give that rubberband effect around 4K when it kicks in.

On the wrong octane and with no supporting mods, map 6 can feel a little lumpy IMHO.

I think too many are running this map inappropriately because it gives them more of a bottom end.

But you really should pay attention to the entire power band because introducing power sooner can have an impact.

Without an intercooler and downpipes, I find that map 4 actually feels smoother and faster than map 6, even though it is inducing less boost in the lower rpms.

Even though I love the bottom end of map 6, I concluded that my engine feels more comfortable with map 4.

Let us know what you find!

saw that too, flashes are great....if done correctly.

I second that. I'm totally stock aside from a JB3 1.22 and I went straight to map 6 after installing it. I knew it wasn't recommended but I read some posts stating that I could 'get away with it' on 91oct so I wanted to spend a little time on 6 to see the maximum contrast between tuned and not tuned. Well, I got away with it, but it was a bit jumpy down low and didn't feel right up top. Map 4 is much better in all regards.

Maybe try map 3 out for a bit and see if you notice anything different.

I've never tried map 6... so far I've only driven map 3. I'm happy with the power from map 3. However, I thought between JB1.0, 1.1, and 1.22, JB1.0 was the smoothest.

But apparently Terry's customer base wanted more down-low torque, so he obliged with more low-end torque. Its nice to have that low-end grunt, but in DS mode with an automatic, its tough to drive the car smoothly.

For tracking the car on road courses or autocrosses, JB1.0 was probably the best version out of the three versions, as it had the best/smoothest linear torque delivery. Too bad a similar map is not available anymore...


I'm pre-29.2 btw... I think I'm still on 26.x.

very nice review man!

[hotrod182]

I'm thinking that the stock airbox will give you more low end torque and power in everyday driving, especially in cold weather conditions. I tested using an open air element in the 1/4 mile. I got better times/traps with the factory air box. This was even after I confirmed that the aftermarket filter had less restriction! I think it is because the factory airbox will at least give you a consistent stream of cold outside air going into your intake tract.

I tested map#6 the other night on 94 octane, and the thing pretty much screamed through the 1/4 mile at around 115mph! Tonight on 91 octane, I can honestly say the thing feels as fast or faster. I raced a supercharged G35, and it was amazing how quickly I would pull away from him. The car is also spinning its tires are around 40mph. So maybe in cold temps Map#6 is fine on 91 octane. I would describe the powerband as fun, exciting, and the way I like it. Maybe tomorrow night I will test the traps on map #6 again on the 91 octane fuel. So no, I'm sure the tune doesn't adapt, but the DME sure seems change as time goes on. But yes, you should either put the DCI on your car, or put the stock airbox back on the other car, I think the difference might surprise you. I have made numerous back to back test comparing the factory airbox and an open air aftermarket filter. Perhaps for an open hood dyno session he aftermarket filter may perform better, but for your kind of testing, I think the factory airbox is going to shine.

If I had brought the car in for service in the past, would they have updated my ECU or is it a customer initiated action (complaining about something and they upgrade it to hopefully fix things)?

Thanks,

You would see it on the bill. Progman update.

this is why I chose the UR CAI....no hot air.

someone really needs to develop a fully enclosed CAI utilizing the stock snorkel and an additional intake tract to allow more air. No hot air coming in at all......my 2 cents.

I agree.
I have the AA intercooler and a very free flow exhaust (catless DPs with the AE exhaust) so I've had no lumpy issues with map 6, but I can see how one would if their car is stock besides the jb3.

Just pass the comments on to Terry.
As you mentioned, he's constantly working on making the customers happy.
Since you want something other than the majority, I'll bet that you'll get a custom map sent your way.
