But being nosy I dont get the difference. I thought a new blank EEprom only contains zeros?! So how to get the new EEprom to work with the IPK?

If its programmed to a new state the T4 program's the data in. A totally blank EEPROM won't work and the IPK usually states mileage of around 600k and chucks up various messages. Do you have phils bin files? The files have the data in to tell the T4 the IPK is new and accept new programming.

Ok. I am a hardware engineer, so software issues are very new to me. First time the empty EEprom resulted 323k on the odometer, after next start 999k999. Nevermind, will try Phils file, but dont know where it is hidden

Good heavens

You chaps have progressed things nicely since the beginning of this thread.
Some of my earlier T4 comments on the forum are probably a bit out of date now but I hope the info and screen dumps I provided have been useful.

At the time I was pretty much doing a one man band and getting anyone to share info especially on ZCS calcs and how to apply them to the car was near impossible to obtain.

Actually that's not strictly true, plenty of people offered to sell me spreadsheet for £2-300 to do the ZCS stuff but that not the spirit in which I worked I was happy to share all my knowledge for free.

I still don't know how to do it but glad it is no longer the 'secret' it once was.

Keith if you look on the community site I uploaded the calculations there.

Have a search under philt4 they are here :-)

Brian helped me out, file is here now, the pickit programmer will be there tomorrow, just still need to find out the wiring for the ICSP.

Could have bougt a new IPK and use the T4, but wanna learn something

Meanwhile I was successful programming the virgin dump of a YAC003850 to an EEprom (many thanks to Brian!), odometer says 000000 miles, but the trip computer display is still dark. Will try to reconfigure when the kids are sleeping, but thought the MC would work instantly...

Silly question Tom, you do have the indicator stalk switch with the computer button fitted?

But yes, it is there! And when opening the door the MC should show it even without touching the stalk switch button

Reconfig the ECUs with ZCS didnt help, the Testbook complains the IPK being too new or something (error 04).

Alternatively I tried to read out the original EEprom, but all I get is FFF7 in all registers.

Tom the lowline IPK eeprom cannot be read in circuit.
The reason T4 is complaining is the IPK eeprom dump is from a 2005 manufactured IPK.
What disc are you using on your T4 DST0006V is the latest (and last) revision
