Navi radio and larger instrument display changing

[gazz292]

Well.. i'll admit that i've screwed up, i got impatient and tried to manually de-solder the eeprom from the KPH IPC i bought from a european meriva (as uplevel meriva B ipc's seem rare as hens teeth in the uk)
and in the process i lost pin 7 (or pin 2) so i couldnt get a dump of it's contents and had a dead ipc.

So when my hot air rework station arrived a few days later i popped the eeprom off the original IPC with the low level display and put it on the uplevel euro ipc to see what would happen.

hot air is so nice to work with for this kind of thing... tho a surface mount tweezer soldering iron would be handy for the led's, as it's easy to burn them with the hot air (kapton tape ordered)

I was surprised the IPC started up... gauges all work, but i get so many menu's... like:



i believe the IPC thinks its now a petrol one, as i dont have the glow plug light anymore (it is a diesels ipc, and glow light worked before i destroyed it's eeprom) but notice the 'bio-power' meter for E85 bio-ethanol.

Battery level as a percentage? some things i get no readings for due to missing sensors i guess, but not sure why battery level wont show, tho it's usually voltage rather than percentage.


I also have to press the cancel button 8 times on starting the car, as i get these warnings:



Some items i will fit the parts for... but 4x4 i doubt will ever make it to my list of mods

oh, and airbag is i believe a stored setting in the IPC, there's 100% nothing wrong with mine, but the insignia's ipc did the same, and both IPC's are from crashed cars... i do only have 2 DTC's now tho, for security code not set in the ipc and bcm, so im hoping that when i can set them i can clear the airbag warning indicator and engine trouble light thats on.

Oh yeah... in the settings menu there's this!!!


Wonder what happens if i activate it? does it shut down all electronics for being jump started.. thinking how corsa's get their bcm and ipc corrupted when jump starting.. or does it up the revs and raise the voltage of the alternator for giving a jump start?

Then i noticed something i didnt think of when using a european IPC in a UK car... this is front and rear right hand doors open:



I guess the rear door open code is left or right, and the front is drivers and passengers,

Took it for a test drive and noticed that the speedo was reading low... very low.. but the needle wasnt catching on anything... it was linear, like at 50 mph on the digital speedo the needle was pointing to 30mph... then it twigged... i set it back to metric mode.. KPH, litres and all that, and the speedo needle jumped up to the right reading.

in europe they have only KPH markings on the speedo face, i swapped my mph dial face over as it lines up right... but when the IPC is set to imperial units, it points the needle at the number in mph.... so at 30mph the needle points to the 30... kph mark on the euro scale,

Very clever but very annoying for me... as i want MPH, MPG, miles and all that english stuff we wont let go of... but to do that the speedo needle will never go past the 70kph marking (honest officer)
The euro speedo goes upto 220kph (meriva 1.3 speedos stop 20mph shorter than other ones) so there's abut three quarters of the speedo face that will never be used.

Now if i put it in metric mode, the needle reads right, but i have no idea if using 5 litres per 100 kilometers is good or bad fuel economy, and i dont want to know i can travel 900kms to a tank full, i want to know how many miles i can go.

Not sure i can change this behavior, i've been told the needle movement is stored in the MCU and not the eeprom, i can hope there's a setting in Tech2 to say it's a uk speedo, but i wont hold my breath... so im likely back to searching for an uplevel Meriva 1.3 diesels UK spec IPC again :(
