Nope, that isn't my wiring. Mine is older than the EZ system . I will send you an e-mail.

Yes, but I don't have an octane coding plug, only an ignition timing basic coding plug. How does the transfer between the two fuel tables happen. Does anybody know what is the function of this ignition timing plug really. Sorry for asking diagnostic questions .

All the sensors involved in the EST system in question are listed in my first post at the beginning of the topic. An inductive sensor (probably what you call reluctor), 1 bar MAP, oil temperature sensor and distance recorder as mentioned in the wiring diagrams. That is all, nothing more nothing less...

Ok, thanks for the replies. It seems that It is going to be a tricky one dumping the ROM. Can someone explain in a more simple way the interaction between the sensors and the ECU, I mean how the signals affect the timing. I know that the main chip has "the brain" of the ECU inside it, and ...

If there is a problem with the other pic let me know, I will try to fix it. The main chip has the following markings: Delco 16048199 169 8507 JAPAN A 004 The document that I found which probably concearns the chip is http://www.alldatasheet.com/datasheet-pdf/pdf/124945/FUJITSU/MB88507.html , but the...

Hi there, my Kadett has a Delco EST system only, it is a carburator model, it was produced back in 1985 . Recently, I've managed to remove all of the silicon covering the electronical components, but i'm finding it difficult to identificate all of the chips included, probably because they are old an...
