The series 2 (or black backed) ODO calculations are completely different and far more complex than the S1 clusters. They are made by two different companies
And I could tell it was under 30,000km because thats the next service due in the cluster

I have a Ve 8.5. I fitted a series 2 SV6 IC without programming and everything functions except the cruise control. No warning lights or error messages. I have scanned with a tech 2 and getting a data/vin mismatch code as expected.
I opened my original cluster and read the data from the eeprom using my Scorpio Orange 5 reader. I found the vin number location with help from this forum. I then got another donor series 1 IC and modified the vin number to match my car. I fitted the cluster and all good excepting the different odometer reading.
Am I able to write the vin number to the series 2 IC without any further issues ? And will the cruise control work ?
The original IC has the white back panel.
I did attempt to SPS the series 2 IC but got a hardware error. I am thinking that once I match the vin number that I may be able to reflash it.
Any help really appreciated

I understand that the hardware is different but was hoping to trick tis2web by changing the vin number and then hoping that it would reflash.

I have looked on the forum for the various codes and eeprom location but haven't managed to find it. Any info out there ?, surely would be appreciated.

I connected a Tech2 and tried to obtain the vin number that was stored in the IRC but kept getting unknown ecu errors. I then connected the IRC to an MY12 VE and tried to connect via the Tech2, same unknown ecu error. If I have the original VIN stored in the IRC, I can get the immobiliser security pin code and then do a reset to the IRC which in effect sets it to a new status allowing me to put a new VIN in.

I also noticed that this IRC had come from a reputable aftermarket enhancement shop that specialises in retrofits. Not sure if something has been reset or the seller on eBay had a crack at eeprom work and wiped the memory of the eeprom. Any thoughts would truly be appreciated.....

Thanks again for the reply. There is an option on the Tech2 for an ECU reset on every module fitted to the car. I own my own workshop and have access to tis2web. The security immobiliser code is required whenever you want to reset an ecu back to a non programmed state. When you reflash the control unit, the 4 digit security code is required to finalise the link. I fit secondhand units almost on a daily basis and an immobiliser pin code (security code) is always required. That being said, I haven't tried fitting an iq unit yet but can definitely assure you that the ecu reset option is there in the iq module.

My eeprom reader is a high quality unit costing more than 1k. If it is unable to read the eeprom, it sends a chip not responding message.
Once again, thanks for your interest and I'll contact you about getting this iq unit up and running as it's for my sons car and very keen to make it happen.

You are correct in saying that different firmware versions are not interchangeable. I have only recently started doing eeprom work so it is all new to me. I was trying to see if I could make it work but already inputting a vin number into the eeprom. I have no problem in doing eeprom vin writing in like for like clusters, ecu's, abs modules etc.
