Mazda MX3 1.6 Immo problem

[i_shot_the_sheriff]

Hello mates


I have this Mazda MX3 1.6l with ecu 0797008560 B6HN and eprom TC97101 inside . The Immobox is Temic BH4A675G2 .

My problem is Immobox ,,,, Immo light is not light 9 out of 10 times! When immo light lights ,,, car starts.....

I've seen that an emulator is a good idea for this problem but for Julie emulator i can't see any modifications on eprom for the TC97101 . Has anyone seen this before?

Thanks in advance

Bump anyone knows?

I know something, but I have two questions:
1- You have car ?
2- ECU is the same what I've make emulator sometimes, like this on photo ?

No problem, I can make emulator also, only read tc97101 memory

Ok, next step This ECU type not start the software immobilizer subroutine, if ECU not see engine speed , so You must test this, best a using an oscilloscope
Emulator is not problem is fully configurable, you can save all the parameters to the emulator needed for the various Mazda systems and also righ codeword (Mazda PIN code)

Engine speed input is ok

Anyway ,,, i'm waiting on the feedback of the client on how to proceed ,,,,,
