V4 vs jb3 , who switched from one to another ?

[BrianMN]

I think this concern is people going with upgraded turbos..and the only one i know with an AT and a procede is Dan.

Enrita? Pretty sure he has upgraded turbos and AT without misfires.

[Terry@BMS]

Peak numbers will likely be the same....however the smoothness will be different.

Plus, the single-gear WOT target is not the bread and butter. It's the daily driving and non-WOT conditions that make the tunes vastly different.

Yep that was the first thing we redid on the G4. Part throttle, transitions, etc, are all buttery smooth and lag free now. CAN data makes it easy.

So all procede AT user are experiencing the missfire at a redline on top end ? I don't get it

C'mon man. You're better than that. Not at all. Read a few posts back. Only a few are misfiring, and it is due to a pre-existing hardware problem (injectors, plugs, coils, etc) The procede is just more 'prone' to misfire. And many if not all misfires are able to be simply solved by contacting Vishnu and having them send custom maps.

Ah i wasnt aware he was AT.

That's awesome, congrats. The word is G4 is going to be very good.

But do I always have to shift early with procede when I drive agressively ? I don't want to do that ?

[Sticky]

I'll pay, independent user - I've paid for 2 jb's, 1 sb2, and a trucking v4! Let's throw the stuff on my car or someone else's and get some $#@! out there. I for one am tired of all of the he said she said on every site.

We will do this, let's just get the G4 out there and then we will do this.

I'm sick of the talking as well, want to see them on the same car.

Ok it may be putting out the same numbers but Terry is saying on auto it's best to redline to get best acceleration and Shiv is telling us to shift at 6300 rpms, so which one it really is and which one is quicker ? I don't get it

The only reason one should shift earlier than redline is to take advantage of peak torque of the engine...in other words, you will accelerate faster if you shift earlier rather than draw it out to redline. Search for a thread on E90 Mr. 5 started on Ideal Shift Points.

Do you get misfires when you go all the way to redline? If so, give Shiv an email and he'll get you fixed up quick.

[BrianMN]

And for what its' worth, Shiv has stated on e90 the recipe a.k.a. 'trade secrets' that makes the engine more 'prone' to misfires on full boost at redline...remember, this is almost always a hardware issue.

And one can move around the tq/hp curve a little bit with initial boost / taper....for instance you can put zero taper of 18psi at redline if you'd like...even though it'd be choking out the stock turbos.

Hey Brian I just sold my jb3 and got the procede but havn't installed it yet, I will this week , I'm just curious if procede is good for AT you know, because when I was reading before I purchased everyone was super happy with procede then when I got it I discovered this whole missfires, early shifting bull$#@!, why is Terry saying to redline it ? if there's a boost taper after the 6500 rpm on procede, was I having the same boost taper on jb3 ? I just don't want to be slower lol that's my only thing if I'm slower with procede than with jb3, I will be dissapointed, I hope not.

Haha no not at all...read my posts. Remember, there are thousands of procedes out there...thousands of Jb3s out there.. the people with problems on the forums don't represent the entire masses. You will absolutely love the V4/V5 now. I was surprised by how much of a difference it was. Yes, the procede is good for AT's. Very good. You've discovered a few threads with a few people having misfire issues at redline..however if they would've called or emailed Vishnu first, they would have been able to get the issue resolved quickly, most likely with special maps that are less 'prone' to this misfire. Remember, if your car's injectors/coils/plugs are in good operating order, you won't have this misfire. (I see your other thread on e90 regarding rougher idle at cold start..most likely a HPFP issue) You won't have a slower car with the procede. Relax

[n54BoostOnCoke]

lol I got you, I'll see this week. =]

[enrita]

i boost 19 psi at 6600 rpm with 1100 ml/min meth/water, no missfires.

guauuuuuuu enrita 19 psi en 6600 rpm ,su coche tiene que ir como una bala...

espero tener mis turbos en breve,veremos a ver que son capaces de hacer

un saludo amigo

[mazdaspeed6]

Enrita what nozzles are you using?

[enrita]

1x 225ml/min and 1x325ml/min. Snow performance dual Stage 3

yes pretty fast ;-) actually getting the car back today after my generator/servo belt broke and tomorrow my license (police did not like me passing them on the highway in full 4th LOL)

[mazdaspeed6]

lol i bet they didnt.. btw isnt that 550 ml/min?

[enrita]

you need to calculate the correction on PSI. Multiple those numbers x 1.85 and you get the flow on 220 psi.

[mazdaspeed6]

Gotcha, thanks!

[themyst]

6AT en route, we'll see if I misfire on the PROcede. Don't even know what a misfire code looks like on the 6MT though.
