ECU definitions for ECUFlash

[strav]

Oops - the link to the downloadable definition package in the first post was actually to the old set of definitions

Now fixed...

I should add if you are using my ROM to add to the definitions database then by all means do so.

Hey WytWun... would there be any chance of you looking at a leggy rom and seeing if you could add a transmission definition to it? would be great to be able to adjust some trans values

Do you know what sort of ECU (H8 or SH2) is in the car? I've been under the impression that the Legnum ECUs were all H8, even in post 2000 cars. H8 auto ECUs actually have 2 separate ROMs: the first is for the engine and the second for the trans. Each ROM is 128kB in size. The standard reflashing cable only works with the engine ROM; getting at the trans ROM requires a wiring mod to the reflash connector wiring to swap the reflash signal between the two wired pins when desired. There is a reasonable chance of finding the speed based shift maps in an H8 trans ROM if you can read it.

If the ECU is an SH2, the auto ROM will be 512kB and that I can easily deal with. You may need the custom read template mentioned in the first post to read the whole ROM in that case.

The wiring mod to the reflash connector wiring mentioned in the previous post may also permit access to the trans ROM in H and late F series Magna/Verada ECUs, provided that there are two wires running to the reflash connector.

Auto cars with SH2 ECUs only have one wired pin in the reflash connector as the trans code is in the same ROM as the engine code.

Already have some auto stuff defined, can define more if required.
