Hi everyone! I have recently replaced S320 power packs with C32 AMG (Engine, ECU, Gearbox, TCU, Fuel Pump, SC pump+cooler)and with all the wiring harness and parts (Except Rear diff), Since the S320 ECU immo chip is damaged beyond repairable, i wipe the C32 AMG ECU with virgin dump , what should i do with it with STAR? Does it need engineer version to make it work? Engine will CRANK and IGNITED if i turn the key in split second, but the immobilizer with come and stop me. Instrument Cluster will show Gear Position.

Also, people said the ECU system of C32 and S320 are different, which needs to program all S class system in order to work with C32 ECU+ C32 Engine + Gearbox(both 722.6) + TCU(Should it be S320 TCU or C32 TCU due to its gear ratio?), but is it true that it cost USD 3800 to program it? If it's true i'm ok, but the dealer said the progress include simple but complicated process of coding of all S class component, is that even true? where another dealer said it could be done in USD 500. I would like to know what is going on if the quotes having a large amount of differences and which one seems to be real? What specific things are controlled by the ECU and need to reprogram? Thank you very much!

All i need right NOW is to make the car start and go 50-60km back to my house, simply by matching the EZS to ECU, can make the car run? what should i do? What expected fault is coming?

If purchasing a China made STAR with its funny offline coding works, I'm also down to it.

The process of engine modifying 3 weeks ago, now the car is assembled.
