RomRaider

EcuExplorer can log a 1999/2000 JECS ECU and also read out it's contents.

Can this be rolled into RomRaider to allow logging and ROM reading.
Editting of Rom is not really required at this stage as we have no way of reflashing it.

the logger and ECU reset would be useful though all in one application.
It would also make road dyno in Dataloglab easier as it would share the same log file format.

I seriously doubt that Ecuexplorer can read that ECU. Logging - yes. Pulling the rom - no. There's some JECS rom floating around on the openecu site, but my understanding is someone got that with the ecutek software.


RomRaider doesn't read roms anyway. Have you tried logging the ecu with RomRaider?

ECUExplorer can pull the ROM, as I've done it from a standard and mapped ECU and was shocked at how little was changed, especially as the remap took into account a larger turbo.

see my post here : http://forums.openecu.org/viewtopic.php ... highlight=

I've tried to connect to the ECU from RomRaider and it doesn't see the ECU/Connect.

Your post in that link says you used Ecuquery - that is just a ram dump, not a rom dump. You did not actually pull a copy of the rom. Ecuexplorer uses an old verion of Ecuflash for reading/flashing. Ecuflash has NEVER supported that ECU.

Yes I used ECU Query, this was left running for a while....
upon return I examined the file contents and searched through the file to find the performance maps.
This was achieved, which enabled me to compare a base Ae802 ECU with a remapped ECU Image.

I already had basic info on the Ae802 base map as had an html file obtained many years ago. Using this enable me to find the maps an plot in Excel and confirm the data matched.

I did post the Address locations of some of the maps on OpenECU i.e boost, boost control, hi octane fuel, low octane fuel, ignition, knock correction etc.....

I am aware that ECUFlash doesn's support it...

sorry but the tone of you email reads that you are annoyed with my comments and suggestions for MY99/00 support...maybe I am just reading it wrong.

I'm not annoyed. I'm just trying to make sense of what you are saying.

EDIT: It is possible to read a portion of the rom with ecuquery, which with some ECUs may allow you to read table data but not code. This all depends on the allowable SSM read range which can vary by the revision (some may only allow you to read a portion of the table data). I'm assuming this is what you did in this case by comparing it to the rom obtained via ecutek.

RomRaider, however, is designed to work with the entire rom, not a partial dump. While there is the entire rom for this particular revision that someone obtained via ecutek, that is only one revision and obviously you can't read any others with Ecuflash (nor flash) so it is pointless to disassemble and work on one rom revision for a new ecu that can't be read or flashed. While it might be cool to mess with, there are many, many other higher priority items when it comes to definition creation that would actually be useful to many more users that we have to focus on.

As far as logging, these ECUs might use an older version of the SSM protocol. Not sure if Ecuexplorer explicitly covers this older protocol - I wouldn't think it does. Perhaps, as far as romraider is concerned, you connection issues are unrelated to the ECU (check out the romraider faq logging section troubleshooting steps).

Just to clarrify a couple of things.
The ROM image read out of 2 Ae802 ECU was performed with ECUExplorer.
One ECU was stock, the other ECUTEK'd (both are my own ECU).

I'm not that interested in Flashing these ECU as I know that subject has been done to death and the only way I am going to be able to do that is become an ECUTEK dealer. I Just wanted to know if I could use this tool to log and then pull into DataLog Lab, but I may well have to stick with ECUExplorer and create a def file for it.

with regard to connection.
I can happily connect to WRX01> ECU as have connected to many and recently achieved 347BHP (Flywheel) from a WRX02 running TD05-18G, FMIC, Apexi Induction, STi Pinks, rescaled (1/2 scaled etc) MAF.
