I think the intent is to have rusefi actually running the engine, but tricking the stock ECU into thinking everything is okay. In "lay-person's" language: The owner tells the manager what it wants. Since the actual work needed is different than what the owner really wants, the manager has ...

Sorry, but can't think of anything off the top of my head.

Have been wondering when someone would point at this. I've used it as a reference for many things Toyota over the last 10 years or so. :roll: It does update fairly often, as new Toyota tech comes out. I've found a few errors in it, mostly because at some points things are over-generalized, but good ...

what's the original purpose of ecu in this vehicle? I recall I've seen a granada from mid 80s with injection-equipped v6. it could be the very same model of v6 engine ;-) for instance, i've found an intake manifold from injector engine and this would be an easy swap (at least i hope so). do you int...

Realistically that's just an idea for some day in 2018

Yep....

And it will self-tune, drive the car, apply the brakes, shift gears and serve coffee Starbucks can't match.

So you would need 'specialized' hardware on the 'main' board... (I'm considering the processor here as part of a 'daughter' board)... to facilitate programming? Fine and dandy. This does, however, put the brakes on my efforts to generate a TMS570LSxxxx board since it would need to be compatible with...

Interesting idea, but how do you get the 'firmware' on it?
I don't see any JTAG or emulation hardware.

Suppose we'll have to agree to disagree. The concept mentioned, though specifically addressing radiator fans and fuel pumps, is just as valid toggling GPIO for fuel injectors and ignition. It may mean a total rethink / refactor of the extant code, to accommodate real time events in real time, though.

High-level functions that influence low-level GPIO, and thus hardware registers, no? Sure, at the end of the day the outputs are toggled thus the registers are involved somehow :) My point was that spending the time to do the calcs and then later changing the GPIO status to match is a waste of time...

russian wrote:FAN and COOLANT tokens would be higher-level functions, not really related to actual hardware registers.

High-level functions that determine low-level GPIO states, and thus affect hardware registers, no?

"Goof-off"?
WD-40?
....

So, basically... and yeah, I'm making it more complicated.... How much GPIO and memory do you have? ;) // Turn fuel pump on when the ECU has been powered on, and it has been less // than 4 seconds since power was applied, or if RPMs are greater than 1 // or if the ECU detects the ignition key is in ...

This thread is a mess :( We have at least three? four? barely-related subjects here 1) the actual board initially created by Sudo and all the preceding discussions 2) VR stimulation in general and VR stimulation application to Honda OEM, mostly using the MAX232 chip 3) a failed (?) idea about using...

A little more detail might be helpful; number of cylinders, for instance... but probably better suited starting a discussion for that in the appropriate section.

In the mean time, welcome, and feel free to ignore me.

Yes. See https://svn.code.sf.net/p/rusefi/code/trunk/firmware/rusefi.cpp

So, apparently, I've spelt it correctly.

Now, more gasoline and H202... need a fireworks show.

I think we just need to figure out how to follow in the foot steps of Live via http://en.wikipedia.org/wiki/Selling_the_Drama Then we would have a budget to do it right :) I also take issue with my designs, but I draw a line at getting done instead of doing it perfectly.

http://open5xxxecu.org/viewtopic.php?p=931#p931 Okay... it's been a week since the accusations were levied and there's been no substantiation of the accusations presented. I am going to lock this thread, with the following comments in closing: These accusations / allegations should have been raised ...

For those interested: TMS570LS3137 Cadsoft Eagle part: TMS570LS3137.lbr It does, as of now, only list the default pin functions. I hope to add the alternate pin functions to an upcoming version. If you have a different part in mind, let me know and I'll see what I can do. It should be easy enough to...

Yep, this is going to be fun.

Is there a diagram representing which pins on the Frankie board do what? Power supply? (Kudos to Jared for using the P-channel MOSFET thing I suggested 01/2014 ( google it if you doubt it ) for reverse voltage protection. ;) ) Did you use drivers that can report open / short / under/over-current... ...

I would wager a guess that the chips general functions can be routed reasonably well. For example, going CW around the header we generally have analog to the left top side of the header. Then misc digital IO (DIO) along the bottom like USB, SPI and CAN are along the bottom of both headers. Then dig...

Often those RC DAC's are followed by an voltage follower op-amp. The op-amp can drive several mA of current and they keep a consistent impedance to the RC DAC. Not sure how relevant this is to your statement but the MCP4922 can source ~10mA per output. Also, there would be a PGA between the DAC and...

There are still some issues to work out with the code. I'll leave it up though, for anyone to look over and maybe suggest fixes.

If we are looking at making an equiv of the discovery can we simply put the extra pins on visas such that we have access but start with Frank features? Also are there really that many more feature pins? The extra pins could be +v or -v. The STM is designed got two later board designs, which often r...

Code reworked a bit: Serial / LCD bits removed. CAM trigger can be set with an offset to correspond with a particular crank tooth. Incorporated one idea I had for trigger tooth pattern generation- see 'triggerPattern' variable below. If anyone has a similar TI launchpad with Energia, or an Arduino, ...

One way or another we would need a synchronization point - either it would be the skipped tooth in the 60/2 case or a separate signal on a separate line in case of 1+4+24 Honda. How would this be implemented with the proposed approach? I'm working on that at the moment. Have the basic algorithm wor...

There are several dev boards / eval kits, but I don't think any are 144 pin, and don't think you'll like the prices.

In 100 pin, you'd be resigned to using either the 0432 or 0332, neither of which have FPU. The difference between those two is 384KB (0432) versus 256KB (0332) flash. The 57004 launchpad board breaks all the pins out to the 3 headers. The underside of the board lists the default function for each pi...

One thing that'll be fun is mapping the TMS570's 144 pins and peripherals to the STM32's 100 pin layout and peripheral set... and what are you going to do with the other 44 pins on the TMS? Just a quick glance at the STM board and 100 pin proc, compared to the 144 on the TMS shows things are in quit...
