Engine not start
I also not able change milage program say: write succesfull but no change in digit on odometer. Maybe i did something wrong ? I press and hold reset on dash during program.

Any solution ? My problem is to install new dash in corsa and adjust milage.
Maybe it's posible disable immo. How ? Rewrite ecu ? possble via k line ? PLS HELP.
dump fro dash vdo with nec included.

Program for pure DOS. In the program you need to press the reset button run daily. Then disconnect the battery for 30 seconds.

Thanks, will test tomorrow, but what about immo ? Any chance to synchronize via k line ? I found pinout for vdo ? How to fix immo problem...

[mes_cal]

You pinout is ok .Desolder Nec with old Instrument and swap to new :)
Or use op-com interface , nec programmer too .(see allegro.pl)

Pantadeo - your program only set new km in dash , not reading\programming all nec memory .

[r6eck]

use op com

Proble is that i don'y have op-com only k line interface made by Viaken and china elm327.
Both are not recognized by opcom

[tachonow]

Dont waste your time only OpCom or Nec programmer can solve your problem.

[gepakg]

you are wrong,when you enter in instrument after intzializing you have window km calibration and inside it you have option read/write whole eprom,i do it many times simple k-line inteface..

OK thanks for answer, There was no way to rewrite all adress in NEC with simple k line interface. Problem fixed via desolder old NEC and put to new dash. Not so easy but possible :) if you have hot air and...
Immo ok, dash works.
Probably op-com interface is way to do so...but if You want to have interface to opel ,Peugeot, VAG and so on it's cheaper to buty KTS ....
