Hi guys,

Well I finally have something to contribute. It seems as though a problem has been found but I could be wrong, figure I'd post it just in case someone else runs into it.

I had a friend send me the above ROM because it would not start in his 2004 EVO. I checked to see if the Immobilizer Hex was set correctly and the immobilizer code. I then sent the ROM back to him and it still would not start, no fuel pump prime, nothing.

I then thought to check the valet features, non were activated. Then thought maybe we should try to disable the Immobilizer. Another friend of his thought of the same thing and changed the immobilizer disable and the car started.

Here is the problem. I check the "for immobilizer function diable set to 0" and it was set to 0, telling me it should have been disabled. Setting this to "1" allowed the car to start.

Isn't that backwards?

If not or whatever, if any of you have a problem you may want to try that.

Thanks for any input and hope this proves to be helpful.

BTW, if you read this Tephra, you have a paypal payment

OK, why does it say "for immobilizer function disable set to 0"? Maybe I'm retarded, but it sounds like from that if you want it disabled, set it to 0. Doesn't it?

Obviously 1 makes the car start so I may just be confused.

EDIT: I'm still wrong....

It's the logical opposite of what you're thinking. I agree, it's badly labeled.

If you think of it as "Enable Immobilizer", then 1 is on and 0 is off. In reality it's "Do you want to disable immoblizer", 1 is yes and 0 is no.

I hope that makes more sense. Again, it's not something that the ecuflash community has created. That logic is from the factory. All we can be blamed for is a silly label. :-p

OK, yes, makes sense thinking of it that way. It's very odd the car will not start even with the 0055 and immobilizer code set right. Hate to see it disabled but it is what it is I guess.

Thank you for the help donour.

That _is_ strange. Did you verify that the "immobilzer hex" value from his original rom is 0x55? Every '04 seems to be, but that doesn't mean there isn't a new one we haven't seen yet.

When you enable (1) and then disable (0) the Immob the first time you turn it off, you will still have to go through the motions with the starting procedures as if it were enabled.

I found this out on my car.

Wait a minute, my car will not start with this bit set to "1" for obvious reasons (evo 8 ecu in a 2g dsm) but when i set it to 0 it starts up just fine. I was also under the impression that setting the immobilizer bit to 0 would disable the use of the immobilizer feature. I though that's how it worked and why it was labled that way in the table.

1 enables it.....0 disables it.

clockworktoy

That's how i figured it worked, so then why is it the opposite in the OP vehicle?

Thanks for clearing this up, I had the same happening with me and that made me confused, now its clear

So in v7 its opposite to every other rom

Actually. I was wrong in the beginning. It is labeled sensically and 1 ENABLES the immobilizer while 0 DISABLES it. Of course this means I don't have an answer to david's question.
