Bluechip tuning

DescriptionWhether you are driving your BMW 320 d for pleasure, business or towing the PSI Powerbox ensures your diesel vehicle will have a smoother ride, with sharper reactions and much more responsive acceleration! It eliminates low, mid and high range flat spots – your BMW 320 d will pull smoothly throughout the rev range with no loss of power. These benefits do not go at the expense of higher fuel consumption, reduced engine life or heavy smoking. Please refer to the information pages if you want to find more in-depth and technical details about what the PSI Powerbox can do for you and your diesel.

Guaranteed minimum performance figures*:


BHP - Power kW - Power Lb Ft - Torque Nm - Torque

Standard: 163 HP 120 kW 252 Lbs 340 Nm

+ PSI box: 183 HP 135 kW 293 Lbs 395 Nm

Difference: + 20 HP + 15 kW + 41 Lbs + 55 Nm

How does the box fit?:


The PSI Powerbox for your BMW 320 d plugs-in on each of the engines injectors. We have rated our tuning box for ease of fitting, in the below table the dark highlighted text provides an accurate estimate to how easy this particular box is to fit to the vehicle based on our previous customers comments.

How does it work for my vehicle?

The PSI Powerbox suited to your vehicle is the CR series Power Box that is for use with diesel vehicles using a high-pressure fuel rail and hydraulic/solenoid fuel injectors. The power increase is achieved by dynamically re-mapping (in real-time) the duration of the hydraulic injector opening times to the ECU input parameters to give optimum fuelling, in strict accordance to engine speed and load. The PSI Powerbox micro-management system works in parallel with the original management system to ensure the smoothest delivery of power and torque.

Excellent thread!

The DMS re-map sounds so tempting and it's undetectable.

My only concern is, can the car take the extra power over a long period of time (plan to keep the car at least 2 years) without causing any advanced wear and tear?

I wonder if the service intervals would be effected?

I was hoping you were going to say that!

The last time I had a car on a rolling road it sounded like it was in pain. I also had to sign a disclaimer just in case the engine went BANG! Filled me with total confidence??!!!

I wouldn't want to put any car through that again.

Is the Superchip detectable? and do they offer free re-maps if BMW wipe the software during an upgrade?

you dont sign anything and they stessed lots of times there would be no problem and there is a warrenty, you would soon tell if it was wiped after a service,because of the 3rd gear takeoff,i can go back at any time and ask for a check up as well superchips offer anymore upgrades if any comes out like gain more miles or power they will do it for free, i am well happy i may go up to this meet and show you lot what the difference is 320d is no match no more with 200bhp,bmw cant tell a thing

Is this something you'd have to tell your insurance company about?

Yes, If they found out and you hadn't told them, your policy would be invalid.

How the might find out is another matter!

Re: the undetectable by BMW thing, I suspect the techs might realise something is up when they road test the car!

But 200bhp!

Torque & BHP Technical Information

What is all this talk of torque?
Torque is the power of a rotating force, which is the product of one of two equal, opposite, and parallel offset forces and the distance between them. When this is applied to a car this means the effort exerted on a shaft to move the vehicle along. When torque is great enough to move a shaft through a given distance in a given time this is expressed as power and measured as horsepower.


Eh?
OK, if you have a centre nut on one of your wheels and then put a socket on it with a 1ft bar (bear with me on the imperial). The car will be at rest until you put a weight on the end of the bar to try and turn the wheel. So if you now put 50lb on the end of that 1ft bar and the car moves, the force that has moved that car from a standstill, at that speed, is 50 lb ft. So if the engine of that car produced the same amount of twisting force at its peak it would have been said to have a Torque of 50lb ft.

Now if you take that theory one step further and double the weight on the end of the bar and let go, the wheel would rotate again, only this time because the amount of force pushing the bar down was greater, the wheel would move off quicker and with more ease. Apply this once again to the engine producing the force and it would have been said to have a Torque of 100lb ft.

So you can see the more Torque you have the quicker the wheel would move off from stationary.

This is all fine and good on a light car as it means my 0-62 time will be decreased?
Yes the theory does indeed point to that, however do bear in mind that if a car produces 100 lb ft of torque and your car does 0-62 in 10 seconds, it is NOT going to do 0-62 in 5 seconds if you give it 200 lb ft of torque due to the inefficiencies of the engine, transmission etc, but it will be significantly reduced.


What about overtaking?
The samne theory applies to overtaking. The more force you can use to make the wheels go from say 50mph to 70mph the less time it will take to get there.

Why is torque important if I tow a caravan etc?
The more torque you have the more weight you can move forward from a standstill. Or in other words if the wheel you are trying to turn is stiffer it may not turn at al with 50 lb ft - it requires more force to turn it. Therefore if you increase the force by 50lb and the wheel turns then need 100 lb ft torque to move it. Apply that to a car with a trailer, you require more force to propel that whole unit (car and trailer) forward than you would with just the car. So once again with more torque you can move your car and trailer off from a standstill quicker and with less effort than you could before.


What about wheel spin?
With more torque available the quicker you can move the wheels from stationary. When this happens the wheels can spin before the vehicle has chance to move and you of course waste energy and move off slower. Therefore you need to alter your driving accordingly if the torque has been increased.


OK before I nod off, how is torque calculated?
The theory (oh no - not that word again!) is that torque has nothing to do with engine speed (revolutions per minute (RPM)). The torque figures depend on the mean effective pressure in the cylinders (MEP), which is calculated by taking away the total of the average pressures on the induction, compression and exhaust strokes from the average pressure on the expansion strokes. That's the theory.....

In reality the MEP (you should have read the previous paragraph) of an engine, decreases at high speed and the torque drops off. So the MEP is calculated from the Brake Horse Power (BHP) figures for an the engine, taking into account the inefficiency of the engine, so now the MEP becomes the Brake Mean Effective Pressure or BMEP, which is measured in lb in sq! Phew - that was easy.


BRAKE HORSE POWER

What is "Horsepower" or HP?
Lets start at the dawn of time - or at least the beginning of mechanical devices. Any "engine" was obviously going to be compared to the ability of the then main power sources to do labour - horses, men and oxen. As most of the devices were used drive industrial equipment the natural comparison was therefore the 2/1 Favourite at Ascot. So, even the pioneers of the time realised that marketing of the new fangled machin'rey was important so they likened the power of their devices to a certain number of horses.

Moving on from this early start, a famous engineer called Captain Thomas Savoury reasoned that if it took eight to ten horses to operate a mine pump 24 hours a day (two horse working at a time with the next pair taking over when the last two became tired), then a mechanical device that did the same job in the same time had 10 - 12 hp! You can move on through history with this through the likes of James Watt but you are not here for a history lesson!


So what is "brake" Horsepower or BHP
Well simply this is power that has been measured on a brake or normally known now as a Dynamometer. This device provides a load for the engine to "drive" against and then measures the torque produced by the engine, which if it is then multiplied this by crankshaft revolutions per minute and adjusted with the standard figure, it provides a horsepower figure


Just some info

Paul, how about a UK2 re-mapping group buy, since with enough interested members at UK2, they could come out to us & knock the price down, perhaps?

No, really, I'm serious!

The way I picture it is this....

Torque is the twisting force that makes the wheels spin. It is what makes you accelerate and it is what you 'feel' when you get a push in the back on hard acceleration.

HP is "the ability to do work over time" it is a function of torque and rotational speed and is simply a way of translating a rotational force into a linear one. The following is ALWAYS the case:

Torque = (HP * RPM)/5252

You can feel torque if you grab a spinning wheel - the torque is what tries to pull your arm out of it's socket.

You can also feel HP if you rest your hand on it. The heat that builds up is the HP.

In terms of the engine alone peak torque is generated at lower rpms in a diesel engine - which is why the diesel can have greater torque than a petrol engine - but lower HP.

The petrol engine can rev higher so less torque can generate MORE hp.

HP only starts to matter when we thing about gearing ... and particularly how long one can hold onto a particular gear.

Since all cars have gears for the fastest progress you need to change gear at the right point. To determine this you need to look at the torque at the wheels in each gear and change up once the torque available in the next gear down is more than the torque available in the gear you are in.

Higher HP cars will be generating high torque higher in the rev range in every gear, so the upshifts will be later and the average level of torque sustained at the wheels throughout the acceleration will be higher.

This means the car will be faster.

Yes, I'm certainly serious Paul!

I've posted in the UK2 thread about contacting DMS & e-maps to sort a price out for a group buy.

If anyone is seriously interested in 'chipping' their petrol or diesel e90/91, then please let us know in the UK2 thread.
