the SRT4's capability to WOT Shift on Stage 1 is one of the best features in those cars, especially from 40-150. it's also a bad thing though if you plan to run from a dig.

imagine having 320ftlbs to the front wheels and WOT shifting from 1st to 2nd while holding @ 15psi, HAHA !!!!

you pretty much spin to redline in 2nd before having to go into 3rd, BUT, with some nice DR's or slicks, the WOT shifting is a blessing. 1.6 60ft's without even trying.

my STi is on the bottom left corner

So why wouldn't it work on a 335i then? Best would be if shiv built this logic right into the procede, no hardass wiring required and one less box to run...

I'm really gasping for solving my launch..some between shift boost would be nice as well..

What is the WOT Box?

The WOT Box is an electronic device that makes WOT shifting easy by reducing your engine's power for a very short timed period while you shift. It allows the synchros in your transmission to mesh easily, reducing the chance of missing a gear and damaging your transmission. If the input shaft on a manual transmission is not allowed to slow down enough it will lock you out of gear time after time. We have developed a solution to the problem by controlling the ignition at the shift point to ease the transition from one gear to another.

[Litos]

How does the WOT Box make WOT Shifting easy?

Our WOT Box momentarily disrupts the engine power long enough for you to make an effortless, fast WOT shift. The result?

Lower ETs - One of our big turbo customer cars dropped their E.T. in the quarter mile from 12.0 to 11.3 seconds just by adding the WOT Box!

Reduced chance of missing a gear
More consistent, effortless shifts
Reduced wear on the transmission
Reduced chance of major transmission damage

[Litos]

How does the WOT Box work?

The split second that you place your foot on the clutch pedal with the throttle all the way down, a signal is sent to the WOT Box that a shift has been initiated. When the module sees the signal from the clutch switch it will reduce engine power by cutting the ignition. The ignition control is a precise timed event that the user has complete control of. The box is capable of controlling ignition from 25 milliseconds to 700 milliseconds in 25 millisecond increments. With a range like that the wot box can even make Mr. Magoo look like a seasoned pro!

The drivers in our test cars describe using the WOT BOX as sitting in the car and going through the gearbox with the engine off!! All the drivers were amazed at how smooth the gearbox was. The transition from gear to gear is effortless and the boost gauge would barely show a blip between the shifts. We were able to test on an Evo8 with a laggy 60-1 turbo and managed to hold 30+ psi through every gear! Even on a stock turbo equipped Dodge SRT-4 we were able to knock 3 tenths off e.t. by simply hooking the box up. Our big turbo SRT-4 cars were able to drop up to 7 tenths off their E.T. with the WOT Box alone!

Litos, all this sounds excellent if it actually could be run with my piggy

Really sounds like it mostly helps laggy turbo cars

Because the n54 does not have a ignition cut rev limiter. I believe Shiv said this a couple years ago. I read somewhere that the ecu will throw misfire limp modes despite there actually being no misfires

[Litos]

i'd go straight to N2MB (Never 2 Much Boost)

i think Jay still works there from my old SRT days.

email for price quotes/questions!!!

I just realised that I have never hit the limiter in this car. A simple catalog of throttle ignition and pedal would tell you all you need to know

Litos - did you just say the N2MB WOTbox is directly to the OBDII port? I am exhausted and not really reading posts intentionally but if you did that is just incorrect. The N2MB for the ms3/6 platform (as an example - like clap mentioned) is put in line with the main sensor wire split into the coil packs, it also taps the clutch safety wire and pedal position wire (going off what I remember from like 2.5 years ago). You set the RPM to limit revs via ignition in a little software they have and when clutch and gas are fully depressed and the rpms get to the desired set point - ignition is drastically reduced.

Way too many pictures of SRT4's in this thread

Talked to Jon@N2MB, makers of WOT box, and here's his reply to clarify certain confusion:

First point to clear up is that the WOT Box does not wire up to the OBD port. Not sure where that came from. We wire directly to the sensors and control the ignition directly by cutting the common positive power wire. The same 6 wires I mentioned before. Ignition coil power in and out, TPS, RPM, clutch and ground.

I don't know who the people are who claim they have "looked into the WOT Box on their 335" are. We don't have any sales records for any 335 cars, and no one has asked us about it. I don't know any reason why it wouldn't work. If it is a car with the required sensors, it will likely work. We've installed the WOT Box on everything from 1980s VWs to the 2011 Ford Mustang GT500.

The launch control in the WOT Box does not mess with timing, as an antilag would. Therefore, the turbo is not exposed as large EGTs as antilag. It is just a rev limiter. The upside is that it isn't as bad as antilag, the downside is that it doesn't make as much boost as antilag.* Everything is a trade off.

The only recommendation we have is that you not use the WOT Box on cars with catalytic converters, particularly stock cats.* The launch control releases unburnt fuel into the exhaust, which burns in the cat. It will cause the cats to rapidly heat up. If you hold the launch control for a long time (i.e. guys who like to make noise in parking lots), you will melt the cats down.

The no-lift shift feature is easy. It just cuts the power to the ignition during the shift for a short time. You keep your foot down through the shift, and retain boost all the way through the shift. The engine is off, so the shifting is easy and less damaging.

Let me know if you have any other questions.

Thanks,
Jon

I'll be trying this out soon, sounds very appealing, let you guys know how it goes..I'm getting the one with both features so if either one works out as advertised I'll be very happy..

They're also running it on mazdaspeed 3 that's DI..

DI isnt the problem. As Clap said you run into a DME issue where it thinks the car is misfiring.

Can it be done... maybe. Will it throw a limp mode... maybe.

Let me clarify, this already works on one 2007 335i

Any more details on this? Is that 07 running a piggy back? Did shiv mention anything in regards to where to install this? Also keep in mind, that this is not a plug and play unit, you have splice/cut wires in the wiring harness, or in your case some of the wires can be cut in the pnp unit of the procede.

I find this pretty interesting because this ecu works nothing like the ms3 ecu. It controls boost with throttle and if boost is overshot, throttle gets shut.

Question sent to n2mb..assuming they get around it somehow..you can email them too sales@n2mb.com, you'll talk to Jon there..

In terms of wire splicing I'm fine with it, he sent me exact pins on the ECU subconnectors to hook into, see PDF from their 2007 install:

http://db.tt/XRYC4xw

WOT Box GREEN - clutch switch BLUE / BROWN pin 2 at switch or BLUE / BROWN* pin 18 at the ECU X60001
WOT Box YELLOW - rpm source - ignition coil #1 WHITE wire pin #1 or WHITE wire pin 1 at the ECU X60004
WOT Box BLUE wire - accelerator pedal position sensor - app WHITE / YELLOW wire pin #6* or WHITE / YELLOW wire pin #7 at the ECU X60001
WOT Box RED / BLACK pair - spliced into the ORANGE wire that feeds all 6 ignition coils. You'll need to work on finding where to splice this by tracing back the 6 power wires from the coil to a point where they join together. Or, you may be able to do the splice at Fuse F01, 30A. See page 4 of diagrams.

For the general directions, take a look at this document:

I am not really intrested in splicing anything, plus cobb comes wout with this stuff for all their platforms. Just curious to see the progress of this box cause it would greatly help the mt guys. Thanks for posting that wiring diagram, however I hate wiring cause its just not my thing lol

Hey I'm all for pnp but more importantly I NEED to be able to get this beast out of the hole faster, consistently, than 2.0 60'..it'd be awesome if that worked, boost between shifts would be a cherry on top

Gotta warn you though, on my gt35R mazdaspeed 3, after I put in that wot box, within 3k the clutch started slipping during wot shifts. Shifting becomes so easy, its actually easier to get into gear then normal driving around town. Curious to see how that ACT clutch holds up with the power/abuse from your upgraded twins during a wot shift.

No doubt if you get off the line with 1.6-1.7 and wot the every shift without getting out of control, you will hit low low 11s
