One of the reasons for all this is to gather pieces for the future board which has to be our own board for the reasons of price & size. Then I say definitely bluetooth. After it gets it's final resting spot it'll be nice to get data wireless. I'd also suggest using USART1 or USART3 then you can...

Oh, by the way by default we use USART3. TX is pin PC10 & RX is PC11 For the 'human readable' part would you be interested in more of a 'live console' approach? I've dug through the console function and figured out how to bind to arrow keys and the like. It'd be something similar to: http://www...

It's been too long since I've looked at Java.

Any chance you could add a scrolling graph?

I thought it might be good to have a thread with what everyone is using. IDE: ChibiStudio OS: Windows 7 x64. Toolchain: Pre-built GNU toolchain from ARM Cortex-M & Cortex-R processors (Cortex-M0/M0+/M3/M4, Cortex-R4/R5/R7). Once I get my workflow defined I'll post instructions. I have been using...

When does the GDI do injection? Is it near TDC like diesel engines? Another thing is that gasoline will evaporate in air, diesel will just pool. You need to atomize the diesel fuel so you get it to a very high pressure so that at the injectors it atomizes. But that's more of a thermodynamic discussi...

http://www.romraider.com/ Cross platform, based on java. The hardest part is you need to try and reverse engineer all the map locations, sizes and scalings. But when you're building your own software you get to know all that ahead of time. With some scripts to pull stuff out of the build files you c...

I think you are flipping PSI and bar. Nope. That's a gasoline engine. I'm talking about Diesel common rail engines where you need complete atomization near TDC. On diesel engines, it features a high-pressure (over 1,000 bar or 100 MPa; 15,000 psi) fuel rail feeding individual solenoid valves, as op...

See item 35320B for the mechanically driven fuel pump $582, and 35310 the injector for $66. There is pipe connected to 4 injectors, so common rail. What I don't know for sure is the pressure. I believe it's around 100 bar, but don't know for sure. I wonder if the driving would be the same as a piez...

Not sure how much this is relevant, but larger chain junk yards will have a 50% off sale for the Thanksgiving weekend.

Unfortunately common rail pumps are 10k+

I'm more of a hardware guy, who can read code, but can't generate it very well. Good. I'm an ME that can code so I have the other half of the spectrum covered. Here's some documents I found on driving a Piezo. Lots of graphs that will probably make more sense to you: http://www.dspace.com/files/pdf...

I just confirmed that this is also the connector for the EDC15 used in ALH VW TDIs sold in the US between 2000-2003. (I.E. what I need for my 2003 Golf).

So at 40 mA I will drain a 60 AH battery in 1500 hours, that's 62 days. I guess that not really an options :( Thanks for reminding be about these RTC boards, I've seen them before - I guess that would be the way to go. Based on the presentation I found the STM4F should have a low power option for j...

External clock everything ON, typical is 86 mA @ 168 mHz with ART accelerator ON External clock everything Off, typical is 40 mA @ 168 mHz with ART accelerator ON All the way down to 2 mA with everything disabled at 2 MHz. Plus there is Stop Mode that uses ~.5 mA and standby mode at 3 mA. The data s...

1700 C is an extreme case. I believe MY turbo starts melting at 750-800. Depending on the turbo.

The thing about EGT thermocouples is that they are very cheap as sometimes they have a short lifespan where they live.

What sensor were you looking at?

Most newer wideband O2 sensors(heated) also have a temperature output, or at least provide enough data for you to be able to derive a temperature from it. I don't know what kind of accuracy you need out of an EGT sensor in a turbo application, I'm not a turbo guy, but I know the stock O2 in my dail...

Right now I have a STM32F4-Discovery board with blinking lights in front of me. Once I get both my cars up and running I plan on dismantling my old injection pump and start playing with that on the bench to see what type of PWM signal it likes. Then figure out how the hall effect sensor reads and th...

For people with turbos keeping EGT (exhaust gas temp) below a threshold is pretty important.

Three different guys, myself included, have independently decided to go with stm32f4discovery - that was based on the combination of price, speed and the availability of a totally free tool-chain. Yep. Although I was looking at the STM32F4-Discovery only as a prototype board. Hopefully in the futur...

Hello. I stumbled on your forum from the ChibiOS. I've been tossing around making a replacement ECM for the Bosch EDC15/16/17. The Bosch EDC series is one of the most popular diesel controllers on the market. Control is going to be much simpler for the first engines I plan on working with (The VW AH...
