I've HACKED the ECM

[Archive]

Screw the EPA(AKA Uncle Sam). These damn big rigs and Dumps are blowin' black all the time. Not to mention these little Jap oil burners. My truck wouldn't put out near as much even if it was blowin' like Ted J's pulling rig.

Geez,
With the site down most of the day, I was afraid 'they' were trying to shut MARCO down... ... #ad

WOW! Do you think the EPA was here David? Got Rob lashed to a chair with a bright light in his face, pressing him for Marco's whereabouts? Hmmm... I think we need a McAffee anti-EPA scan. Might be bugs.

Marco, If and when you figure this out, I'd be willing to purchase a laptop to carry onboard permanently. Hopefully, we could wire it into the MAP so that we could adjust timing, fuel, etc. from the driver's seat.

With a little more ingenuity, we could connect a fuel flow sensor and one of the onboard hp/0-60 computers and then we would have all the data to figure out which settings were most efficient, most powerful, etc.

Oh yeah, don't forget GPS stuff, also. How about it Steve St. L?

This could be the next big thing. Put me down as a beta tester!

MARCO,


All we need,is an ecm out of a 275/660 motor. Down load it,and compere the maps. Sure sounds easy. Hell i,ll buy it for you.

Before we get too far down the road on this thread. Cummins does offer the interface kit to allow you to talk to your truck ECM. I'm not sure if it is compatible with the DC interface, nor do I know what one would cost. I will ask the local Cummins techs on Monday. Meanwhile if anyone else has already watched them connect the truck to the computer, did you see the cable they used? That is what we need. The software won't be very complex since Cummins only requires a 486 model computer running Win3. 1 to service the system .

Hey Big Carl 64,
The cd changer is a pioneer 12 disk changer. I came with L brackets that I boltd to the floor by clamping it between the seat frame and the floor. works great!

as a side note I just finished installing a set of 275 hp. injectors. WOW what a blast!

I had once talked to a ONAN mech. that working on the same equiptment pad as me, and asked if he had the software to fool with the ISB. He did not because he only worked on CAT but he did say that the guys that worked on Cummins did. So if you have a friend that works on ONAN Gensets maybe this would help on hacking.

Ninearrow, GPS would have too slow of a refresh rate to give accurate performance numbers. I looked into this heavily when I designed and built a rocket that boosted to 620 mph in 3. 9 seconds (12 lb rocket, 4 inch diameter, 7. 5 ft long, peak altitude 8800 ft on a K550 reloadable motor - 550 newtons of thrust for 3. 9 seconds). Originally I was going to use a handheld GPS and even thought about designing a circuit board around a pentium chip (way faster than the chips in handheld GPS's) but it would still be WAY too slow. I designed a circuit board for it that used pressure transducer's to gauge altitude for the deployment of parachutes and the recording of altitude data - it records the altitude every 1/100th of a second (typical GPS refresh rate is in the . 5 second range). GPS is great for things that don't change speed quickly and are fairly predictable - horrible for things that accelerate quickly (even though our TD's don't go 0-620 in 3. 9 seconds they are still faster than GPS can handle to calculate acceleration). The current performance comps out there (I have a g-tech) use accelerometers (sp?) to gauge acceleration and that was the route I was headed with my rocket before I ran out of enough spare time to play with it more. The problem I was dealing with (boy is this getting off topic - sorry) is that when you get close to supersonic speeds there is a pressure wave that will hit a pressure transducer that causes a spike in the data. I have a motor that puts out double the thrust (1100 newtons versus 550 newtons on the motor I flew) for half the time and the rocket should go supersonic nearly off of the pad. I wanted accurate data and GPS just simply isn't fast enough for that and after my thinking about it wouldn't be fast enough for vehicle performance use either. I think that with current technology the best option is to either use accelerometers or a laser mounted outside of the vehicle as some high end performance computers use (some magazine's are using the laser setup now - replaced the 5th wheel of the older systems). Sorry for the kind of off topic post here guys.

Mike B,
Got a feeling Big Carl was refering to the other changer you have installed.

Guys, S T O P, S T O P , slow down a little!!

I'm Italian, it takes me a lot of time to type in English. Keep that always in your mind.
If you don't see me reply suddenly, it's only because I have to find the time to do so.
Now let's see...

I'll quote some of your posts to answer, I hope, most of you.

"Cool, that is great! I'm a computer programmer and very technical person. Maybe I could help. What kind of device did you use to connect to the ECM?"

Thanks Carl I'm sure you really want to help me, but I can do that on my own.
And most important, I WILL NOT SHARE ANY INFORMATION WITH ANYONE!
Don't ask me about tecnical details, you'll get NO answer.

That's a great point!!
Have I done anything not legal??????????

I really don't think so!
It's MY truck!!!!
I'm not using any kind of soft/hardware which isn't my property. I'm not working with cummins stuff. Maybe someone could say that I'm modyfying their stuff. Hell, than I couldn't have changed the tires on my truck since it's a Dodge. NAH, they can't get me here.
EPA... . How's said that a mofifyed ECM can't pass EPA?????
If that was true, the RV engine can't pass EPA???????
I think Cummins ****ed something with their ECM program. I don't believe that more power has to mean more pollution.

That's another good point!
TST used Cummins software to recalibrate the ECM. I'm N O T!!!
How can they stop me???
However I'm a honest person, I'll talk with a loyal about it. IF there is something I couldn't do legaly, I'll quit!

Maybe you get payed for typing on TDR????
If so, tell your boss that I'd like that job too!! #ad

Ok so far, what I'm thinking about, is this.
WHAT??? Should I change in the ECM?

I mean, what would you like to get?
More power? More low/high end grunt?
Better MPG? What? What?.....
Let me know.

Later,
Marco.

why not

Marco, I am glad to see you are not in the clutches of the EPA #ad
We were worried!

I have employees since I am allergic to work!
The only time I get any work done is when the TDR site is BROKEN!! It's brutal when the site is down #ad
Waaa

Marco, some ideas for a better ECM program;

Allow higher boost levels, don't cause the pump to defuel @ 2volts from the MAP
sensor. Change the 2v limit to 5v, or ?

Allow more timing advance, say 16 degrees. I suppose a curve would be in order? I imagine decreasing timing at idle would make for a quieter engine.

Optimize fuel delivery, no spikes.
A flat power curve is best?

Marco, if it's a pain to type in English, just type in Italian, we will translate #ad
