ECU compatibility question

[Renarl]

Hello,

Hopefully someone with more detailed knowledge can tell me if this VEMS unit will work or could be made to work with my 20vt. If it can be made to work, what would be needed and would it make sense cost wise.

Here is the VEMS - http://www.ebay.co.uk/itm/VEMS-progr...item3a6efeae6b

No buy the plug and play version. To confirm if this is viable you would need the vems serial number and then check with Vems hu. You would need to make an adapter which isn't too bad if you have the pin out but you don't know how that ecu has been built and also it could only cope with 1.5 bar boost. A standard audi ecu has the 4 bar map sensor which makes me think this has been build for a different car.

VEMS v3.x ECU with Motronic55 connector and internal MAP sensor
We recommend VEMS ECU purchase from HERE or vems.hu resellers. BEFORE purchasing (claimed new or secondhand) VEMS motronic55 controller from third party, negotiate the serialnumber, and write the serialnumber (vemstune displays serialnr on the statusline when connected) in the contract (and insist on void contract if serialnr was specified wrong). If serialnr: 2595, 2731, 2934, 2904, 3321 contact us.

Thanks, this was really useful information

Uhm, you can make this work on Audi 2.2.
Yes, you will need to work some magic with the soldering iron, and swap some parts, but it can be done.
Might be easier to start from scratch though, and just buy the bare board, an old BMW motronic to get the JPT-55 and box from, the drivers etc... if you want to go that route.

Why do you need VEMS anyway?
