I think we just narrowed down to bad injectors ..more to follow ..doing a few more tests .. Sent from my moto g power using Tapatalk
Hello again everyone, I am fairly sure that I will be proceeding with the 'Immobilizer Delete' option offered by ECUDoctors in Florida. Any thoughts (Pro or Con) on this decision are appreciated. Thank you. Regards, Les
Externally installed immobilizer delete boxes don't really delete the immobilizer at all, all they do is simply mimick a positive response to let ECU think everything is ok. This doesn't help when you have genuine wiring or other hardware faults with the immobilizer system! I think this may be seen as ok if your immobilizer isn't faulty but if it fails or has other lurking issues none of this will work and properly you could get into a whole heap of pain.. I spent time to do a full immobilizer deletion property several years ago for the F430. You can actually get the immobilizer completely removed in software out of the engine ECUs, pm me for more information. That is the engine ECUs then don't care about any external boxes then and the big benefit of this approach is you don't need any boxes attached which could fail or go bad in the future. It's a pure software delete thing, this means you no longer need any external boxes fitted nor any use of fobs to start engine. It's the much cleaner long term solution and with much less to go wrong... Sent from my CPH2145 using Tapatalk
Trev, can you make any sense of the wiring diagram in this post: https://www.ferrarichat.com/forum/posts/148598946/ When the Immo ECU sends an immobiliser unlock signal to the RH ECU, is the unlock signal memorised (by the RH ECU) until the ignition is turned off? After receiving the unlock signal, does the ECU activate the relay, allowing comms between the RH ECU and the other devices in the diagram? If you look at the diagram, once the RH ECU activates the ECU, the Immo ECU is no longer in communication with the RH ECU (via the relay). This tells me that the unlock signal must be memorised.
Hello All, I finally got the car home a few weeks ago (it was immobilized for almost three months). My independent mechanic had to give up when it became apparent that this was a Ferrari Dealer Repair only. I was finally able to get it into the dealers shop and the car was diagnosed with a bad Immobilizer ECU. A new ECU had to come from Italy and it was replaced along with the ignition switch antenna. This is the only F430 that the dealer has seen with this issue and they could offer no explanation as to why this happened. Glad it is finally fixed. Very frustrating exercise. Thank you to everyone who offered me advice. Regards, Les
