It will take a dealer version of ET along with Cat factory passwords to complete the programming. ET will need factory passwords to a C15 software to C13 software. Ansys 11 Keygen Download Free. If you do not have a dealer version of factory password ***** You will need to let the local dealer program it. I wish it was easier. Ask Your Own Medium. Oct 27, 2011. A friend of mine just acquired a program to hack the cat ecm without having to have the cat passwords some kind of a password cracker anyway he can now cahnge the personality codes like from a 475-550 etc change the fuel settings the whole nine does any one have any idea where he got this all he will.

Not exactly The boxes ###### timing, by lengthening the injector pulse width after the ECM's normal pulse width. PDI's tuning of the ECM lengthening injector pulse width taking the start of injection only from the engine. In the timing tables under full load, the injection pulse width starts earlier to have the center of the injection cycle timed according to the timing tables in the flash file. PDI moves the timing event up to burn the fuel completely, this increases cylinder pressures, but any increase in power does.

The boxes injection event is so retarded, because it can only add length to the pulse width at the end of the injection cycle that fuel is left unburnt and high exhaust temps occur along with the potential for scoring a cylinder.

I would think you could possibly make 1000hp with those injectors, Acerts run multiple injections over something like 60 degrees of crankshaft duration so the injector has to flow a fair bit in the time its on to counter the time its off for in that 60 degrees, in theory if you turn the injector on for the whole time you should get a lot more fuel. On the topic of duration vs timing, there is always more than one way skin a cat, so to speak. Horsepower (actually torque) is a direct result of average pressure above the piston on the power stoke (that would be net pressure when you take into account the opposing force/pressure from the compresion stroke). So the question is how do you get the highest average pressure and still hold the engine togeather?

(Bosch has some great books on this topic by the way). We can do two things to increase this pressure; 1- increase the injection duration, ie turn the injectors on for longer, this holds combustion pressure in the cylinder for more crankshaft degrees as the piston travels down the bore. This does not increase peak cylinder pressure as peak cyinder pressure occurs near TDC. The limitation to this are because as the piston travels down the bore pressure drops off so quickly there gets a point were sufficent combustion pressure and heat no longer exist to burn the fuel and all you are doing is washing the bores with diesel (one of the reasons you hear horror stories about boxes). This is the method all boxes, including edited ECMs use (I'm not talking timing yet).

2- increase the amount of fuel delivered in the same amount of time. Hp Mini 2133 Drivers For Windows 7 Free Download. This is your bigger injectors and steep ramp cams.

This method doesn't add fuel late in the stroke so you do not get the bore washing but to increase average pressure in the same amount of time means raising the peak cylinder pressure. Increasing peak pressure will ususally improve fuel economy due to some complicated thermodynamic but V8Lenny sums it up good with less duration is less time for the heat to escape into the cooling system improving efficiency. The down side is the higher peak pressure puts extra strain on everything but in particular (on a cat at least) head gaskets and big end bearings.
