SWAP Vectra b 2.5 v6 new ECU

[gonzoo1991]

Hi I have engine with ecu and immo i500

But my ecu (i500) is not good. I have secound ecu from 2.5 v6 Omega.
I would like to change the memory and map from ecu(i500) to ecu 2.5 v6 omega.

This is motronic 2.8.3

Please help me, meaby only memory swaps? Where are they?

What is wrong with i500 ECU? Those are very robust.
Post fault codes. I just my be a wrong immo.
Easy to immo off this ecu.

[gonzoo1991]

I cut off three solenoids and connectet The resistors
When the engine is turned off, it will only go out after 9 seconds...

I have Good ecu . When i Switch map and eeprom but i dont nie where is it eeprom.

Just leave the solenoids connected and blank off the butterfly's (you wont feal any difference in performance mind you)

EEPROM is a 58379 (Bosch proprietary number, it is actually as Microchip 24c16) circled in the image:

Hi, i bay new ecu and switch 24c16 and bosch 58379(i500) now engine working good,

But i have two problems now
Its possible egroff in this ecu?? and off all vacuum flaps?
And
1000-2500rpm engine working slow but 2600/2700-7300rpm working good


Do you have any sugestion ??i500.zip

Just block the EGR pipe, leave solenoid connected. Same goes for the flap solenoids.
What camshafts do you have?

[gonzoo1991]

Camshafts is irmischer
This engine is original from vectra b i500 but now is in Vectra A GT.

[Kic]

Irmscher do not make camshafts, you have "G" Camshafts from MV6/i500 engine on the intake.
That is standard on the i500 X25XEI and with that setup it is normal for the power to be shifted higher in the RPM range.
This is an old car/engine. replace MAF, IAT and O2 sensors if you want to troubleshoot it further.

[gonzoo1991]

Hi,

Look, now the engine looks like this..
Attachment 595905

o2,maf, and iat sensor is good

When MAF sensor is connected the engine-working very bad..(0-7300rpm)
Only working good when disconected MAF sensor but only 2600/2700rpm-7300rpm but (0-2500rpm still working very slowly/bad)
in the engine is
intake from Opel Omega 3.0
exhaust manifolds 3-1
reamed channels in the engine head
and i in the engine dismantled stepper motor


maybe tomorrow connect new fuel pomp (4bar) becouse maybe here is problem...
Now in the car is orginal fuel pomp from vectra A 2.0 GT.

Do you have any sugestion ? I'm sorry for my language
