INSITE Pro Software

Oh, and by the way, some manufactures have application notes to help get you started. For example, one of Microchip's is: AN738 "PIC18C CAN Routines in 'C' ".

 

[Diesel Freak]

well, I know CAN is a shotgun approach to device interfacing, and it is becomming a major PITA, so I think I am going to deal directly with the memory.



I think this is the chip... . correct me if I am wrong.

then all you need is this little goodie.

Hey I just realised something... those of you with Power Pucks, if you want to look at the data stream, I wonder if it is possible to use the serial port on the Puck to capture it?



I would first use an "O"scope to first see which pins to tap... and then be VERY careful!

my information mining has brought a new gremlin to life.



The Microcontroller PCA on the Injection pump.



This will limit the maximum HP regardless of what the ECM tells it.



Remember than CAN is a two way street between the Pump and ECM.



If the ECM sends an order to the Pump that is outside of the allowable limit of the pump programing... the pump will interpret this as an error and continue to do what it's own program tells it to.



to make a long story short... . to achieve Maximum HP the Pump must also be reprogramed... . or you will be limited to just a little more HP than a CPC fueling box can provide.





WOW I have completely monopolized this thread

 

[TxDieselKid]

so does that mean your talking to yourself???

I see your point. I think that Marco needs to jump in on this. I don't know if that is exectly true or not but it would make cents. I don't know though because the ECM is what defuels the system when it reaches a point, so you sure it's not the ECM just hitting a point?

well, the pump could either detect the erroneous signal (data bits 5 through 13) and not do anything (take it as a signal of zero) or send an error code to the ECM and the ECM in turn defuels

... . this is pure speculation.



is this as clear as mud?



here goes



data bit 5 is a page selector. either 0 or 1.

data bits 6 to 13 is the 8 bit value (1-256) that "should be" contained on the selected page. If the value is not in the selected page ie. not in the programming of the pump... the signal is dismissed or regarded in error.

Sorry...

"My computer has fell and it can't get back up!"



Forgive my absence for a bit, gotta catch up and chime in...

Had to 'clean house' on my computer... been following the thread as best I can from work.



I will review and post any of my findings ANYONE might find interesting on this stuff. And DF, no, you are NOT ALONE!!! just look at how many views of this thread there are. Still at work and gotta play Catch Up here. will be back.

Intel AB28F400BR-T80 chip

Well at Arrow electronics it is $13. 56.



who wants to pitch in for an emulator?

You have discovered the ECU Limit

DF, I see you have arrived at the fact that the ECM won't be able to exceed the limit within the computer on the pump. This limits you to the performance of the EZ box. To make big power you still need to tap the pump wire like the Comp box does.



This means there is no 350 hp program/ECM without solving the problem of getting past the limit of the computer on the pump. It wish it wasn't so

 

[Diesel Freak]

ok, here is another brain teaser... ...



Is it possible to reprogram the pump?

Is the memory replaceable?



Anyone have a pump apart?



I need a CLEAR pic of the Microcontroller PCA!





HVAC, yes the limit is there for all CPC fueling boxes. They all increase power about the same ammount. The only difference in CPC boxes are the external options, and from what I have gathered... .



Power Edge EZ... . boost module, aggressiveness of fueling at low boost



Van Aaken CpC (BD PnP)... . ease of instalation, soon to be the ability to turn the box off, and boost module



Diablo Power Puck... . programability, ease of instalation



all other CPC boxes are one of the above that has been renamed and sold under another supplier..... but we already knew that



This brings me to another question.

What is the MAD ECM going to accomplish that a CPC box and a set of 275's can't ?

Diesel Freak,



You say:



"my information mining has brought a new gremlin to life.



The Microcontroller PCA on the Injection pump.



This will limit the maximum HP regardless of what the ECM tells it. "



Just to make my answer as short as possible.



There in NO such a limit in the VP-44 computer.

Period.



Oh jeah, just another 0. 2 cents. If you need a : " CLEAR pic of the Microcontroller PCA" then open YOUR VP and give it a look.

I have done it... You?



Thanks,

Marco.



P. S. HAVAC, HAVAC, HAVAC... ... .

 

[Diesel Freak]

yep... it is completely incased in epoxy.



That question was presented to get more people involved in this.

 

[Diesel Freak]

Marco, if there were no limit in the pump PCA programming, then the CPC type boxes would produce more power than they do.



And please do not tell me that this type of box can not process the signal fast enough..... The CAN signal has a maximum baud rate of 250000 bits per seccond. A CPC box can be made to be completely transparent to the ECM and pump at this data transfer rate.



I want to see some dyno curves for your ECM in a stateside truck using US fuel with stock injectors. My guess is that it is no more than 300 flywheel horsepower.

That solution just makes me droooool like Pavlov's dog in a belltower at suppertime.
