RE: And so it begins... work has begun on ecueditor v3.0


Justin a small issue with gen 1 .bins, the Au has been grouped with the EU , not sure when this happened seem to remember seeing it like this for a while , but the EU has an o2 sensor and AU does not , it throws a fault code,
had to tell a couple of guys lately to use the US bin to fix there fault code ,

I will fix that up Greg, i have not done much in v2.5 Gen 1, can you send me the bin file as i dont seem to have it?!?!

Cheers

-Justin.

Justin, about 7052/54 flasher, have not found documents yet but i will
You dont got a "sniffer" for the serial lines and then do a flash/read with FDT and maybe it will give you all commands/responses needed?

Got one 7052 and one 7054 ecu here so i can give it a go later this weekend or beginning of next week if you want?

Thanks Twice, John send me through a document with exactly what I need, i will take a look at the code over the next couple of days.

Great :) Do you mind forwarding it to me also? Writing some test flashers is good for learning.

Thanks man, noticed i already had that hardware manual. :)
Will do some testing as soon as i get the time.

Cheers guys!

Ok, so it looks like you have to

  • Sync the baud rate to 9600 or 19200
  • Upload a kernel to programming control progam area
  • Interact with the kernel to flash the ecu

There are kernels and source code available under the FDT\Kernels\ProtB\7052\Renesas directory

So will need to look at the kernel code to see what functions to call over the serial interface to erase and flash a new bin file...

Be cool if anyone knows of some code that shows how to do this...

I'm not a programmer, but I'll try to do some snooping if I get some time. I knwo the subaru guys have been flashing forever and they use the same chipset on some cars. They have a fair amount of support so they've got to know a great deal about it.

Thanks John much appreciated. I think it is a worthy addition if we can eliminate the need to have FDT installed.

When we anyways need to use the kernel, maybe we could look at disable erase on connection in the kernel.
Hence reading through serial would be possible also, saw Brix had successfully made it. Dont know if the kernel is "human readable" though :)

Now its getting really interesting though most bikes i am able to test on are the old GSXRs not implemented in EE.
As far as all i have done only diff between 7052/54 have been memory size and map count. Hope its same kernel and commands...

I am making great progress on flashing SH7052 without using FDT directly, i have written the code to Sync Baud rate, upload micro kernel then upload main kernel, next is erasing and flashing new bin file, its all fairly logical so far.

It may be possible to read out the bin file, i will contact Brix and see what he has done...

J can u check the inj balance maps? Something is messed up. If i change the balance on B mode map and then open the bin file on the older version2.5 the B mode is unchanged and instead of that the C mode has the changes i made.

I made some more major progress this week, i have just got SH-7052 flashing working for Gen 1 Hayabusa in ecueditor v3.0.

This is really cool in that i have managed to write the flashing protocol so that

  • Any Com Port can be used to flash the ecu (i.e. no longer has to be COM 1-4)
  • You no longer have to download and install and configure FDT to your PC to flash

All of the code to flash the ecu is now coded directly into ecueditor v3.0, this should really make it easier to flash Gen 1 Hayabusas

Can i ask that guys who have access to Gen 1 Hayabusa's test this flashing functionality for me, i have tested it on the bench but there is nothing like some real world testing

Cheers

Just a few ideas I had when tuning on a bike I just finished up a gen 2 conversion.

What about adding a similar feature to compensate for installing larger injectors, similar to what is used on the gen 1? not sure if this can be easily done if not no biggie would just make tuning a bit faster if larger injectors are installed.

Injector size compensation was in ECU editor in the past, but it was never really used. If I am not mistaken, it is not really programmed into the base ecu compensations as it is with the GEN1's. It has been awhile, but the ecu coding may have only trimmed the fueling for the secondaries.

If you are using both sets of injectors and dset them to 50/50 you can just scale the main fuel maps accordingly. With very large injectors get really small. The new version of Ecu Editor will use the 24X numbers to help to increase the resolution.

Ok yes I got the tune pretty close by just decreasing the values 25% or so at a time. It has a single set of injectors.
Yes with big injectors the numbers got pretty small most of the map ended up just at 100 or below.

Another thing I have came across and seems to be getting more popular is bikes that have been dry blocked. How hard is it and has it been considered to have the ability to "lock" the engine temp similar to the IAT?? I have previously used a resistor to do it but figured if it could be done through the ECU it is less prone to fail and much easier.

I actually discussed this with Rodney Williford and decided that it would probably be best to see about including air and coolant temperature fueling and calibration curves if practical. This would allow programming or change-out of the sensors. If that is put in, the ability to lock all coolant enrichment out could also be added.

I noticed on my bike that sometimes teh coolant was not at 60C even at the end of a pass. With current strategy, it was changing the warm up enrichment throughout the pass.

There is a big list of things here http://ecuhacking.activeboard.com/t49472005/comments-observations-etc-from-a-weekend-of-heavily-using-ec/

thatI jotted down over the weekend.

Ok great news and that was my concern is that the enrichment would be active during a run.

Nice work as usual John.

Now that you mention it, I may need to put a resistor in my coolant temp sensor to fool it so it doesn't go into enrichment. Makes for a head scratcher when tuning sometimes.

yeah, i use 160f gauge temp as my very bottom temp to start tuning and i'm sure its still compensating there , but if i go much higher i run into the other end of the scale too quickly

I made the decision to rewrite the software from scratch and branded the new software Woolich Racing Tuned software.
