Wow yeah i see its been 3 weeks since my last post!

Time flies!!

Anyhow, here is a quick update:

Prototype 3 and 4 are 90% done!

Need to do the wire mods, electrical checking to make sure im not going to fry the cpu, then put on cpu, program and thats it!!!

My friend back home has also been very busy and havnt had time yet to get a video of my porsche riding with the new software.

He should be able to do it monday if nothing goes wrong.

And just to make everyone a bit more excited, attached is a photo of the prototypes in progress!

Tomorrow I will send messages to finalise who is getting these two, I am running out of time tonight.

Dankie vir jou tyd en jou moeite!

Ok, another quick update.

My friend back home and father helped with loading the new software on my prototype in the car.
And I found a few problems that needs adressing.

When the board is in firmware update mode, then the injectors are opened (stupid mistake on my part)
I also need to improve the connect/disconnect with the windows software
Also need to slightly change the default fuel map, it still has my testing options in it, which also result in injectors opened when engine is not turning.

Due to all the time that the injectors was opened and the long time that my dad and friend took to do the programming my cylinders are now full of fuel.

Anyhow, will have my dad remove plugs and let it dry out over the next day or so, will then test again.

Will give an update soon!

(I also had a japanese test so I did not do any hardware the past few days, will continue finalising the other prototypes tomorrow and on the weekend)

Just found this thread and read it from page 1-4. Keep up the great work and best wishes with your studies.

Cheers M8!

Ok,

quick update:

I am having problems somewhere in my code. I keep on overfuelling the car. Doesnt want to start and after some turning of the car the cylinders are full of fuel

I am trying to get to the bottom of that problem, but the progress is going slow. I am now busy checking the remaining prototypes and will get then out as soon as I have sorted the fuelling problem.

Dont lose hope! I am working on it

Ok another pre-xmas update:

I found the problem with flooding of the car. Microchip's sample USB code that I used executes a lot slower than I anticipated (and what they stated in the documentation) meaning that the injectors stayed open for too long thus flooding the car.

Also Microchip's bootloader code interfered with the rest of the system, causing uncontrollable interrups delaying the injection for long enough to stall the engine.

I am busy replacing the bootloader code, but untill I fix it I cannot send out the other prototypes. Seeing that without the bootloader I cannot send code updates to the testers.

I am busy working on it and seeing that I am not doing anything much for xmas and new years I will have some time to work on it.

Will keep on working and give updates!


Also Merry Christmas and Happy New Year to all rennlisters!!!!

It's a little late but it's been a while .............

.............. Happy New Year .............


Any progress?

Volla

hi everyone, thanks and merry xmas and happy late new years to everyone.

there has been some progress. The first prototype in the car got damaged when my dad handled it and shorted out. The second prototype is in there now.

i have fixed many...many...many bugs in the microchip usb code, and changed big parts of the code from polling to hardware interrupts.

on my test setup it seems to be working 100%, needs to be tested on the car.

I have an epically huge life changing exam in the first week of august, so eveything is stalling at the moment because of those studies.

during august/september i should finalise the code, and have it tested.

sorry for me being so quiet but things here in japan never ever slows down and they expect me to keep up.

Have fun everyone! i will update as soon as i can and I have ot forgotten/given up on this project! it is moving forward, just a lot slower!

danglerb

I"ve always preferred polling to irq, why do you like irq better? Have a good exam.

Volla

I also prefer polling, but because the microchip usb code does not execute in a predictable manner (the same function call can execute in from 60us to 350us, and that is screwing up my timing severly.

Microchip usb code is actually appaling and that forced me to make interrupts, so i can interrupt the usb code to get the injectors to open and close correctly.

I had problems where the usb will repettitively delay the code so much that the injectors remain open long enough to hydrolock the cylinders.

anyhow, it looks to be sorted now, needs more testing!
