Ecu tune for 98 1.8t aeb

[dcsantos]

I have a 98 a4 1.8t and looking to get my ecu tuned by most likely Unitronic, the question I have is how do I know if my car will allow for direct tuning through the obII port or if I need to send my ecu to Unitronic. I called the shop where I'm going to get this done and he said because how old my car is I might need to send in my ecu.

Anyone possibly

call unitronic

Your AEB is a 557P, and that ecu is not flashable, meaning they need to physically solder the chip to your ecu.

Does this go for all 98 a4's or is it possibility I can still be flashed my 98 is a 98.5

The 557P is flashable. I'm just not sure if tuners give out flashers for it, but it is definitely flashable via OBD. No need to solder.

Maestro has a stage 1 and other files for your car.

When you guys say 557p is that a number that should be listed on my ecu?

Yes. On top of my head, it should read out 8D0 907 557P.

I believe Unitronic flashes their stage 1 files for that ECU, but they require the ECU to be sent to Canada for the BT files.

You used to be able to check on their website.

So your saying if I get a bt tune I'll need to send it to Unitronic? Because I want to tune my ko3 with Unitronic so it should be flashable through the obII?

[dcsantos]

I'm looking to go stage one+ will that matter?

I believe that will be a flashable upgrade, but just check unitronics site.

Just called the place I will be getting my ecu tuned with called "mobile one in glenview il" and they said my ecu was flashable which is 8D0 907 557P. Can't wait to get my stage one + from Unitronic !
