ECU test

Post by Ganio » Mon Feb 01, 2016 3:47 pm

Hey all, quick simple question. I just bought a 97 GLT ECU to be sent to get mapped and upgrade to 4.4. I bought it off of eBay and believe that it is most probably functioning properly, but I would like to test it before I send it out. Can I just pop this in to my 96 850R to make sure that it does work? Or will it be all weird since I have a HPT instead of the LPT in the GLT? Will I just get less boost? Will it cause the interior to burst in to flames and the paint to peel? Will it...

Also, I was planning on sending it to ARD to get mapped. Is there a better shop? I have heard some mixed reviews in the past, but I also have heard that they do pretty great work too.

Thanks in advance

It won't run right but as far as I know it will run and if it does then the ECU is good. I have nothing but respect for Lucky and ARD. The guy has forgotten more about Volvos than I will ever learn.

That is what I was expecting. I just wanted to be able to verify that the ECU does work so I wouldn't have to find out after the return period of ebay expired to find out that Lucky can't do anything with it. It wouldn't "hurt" the 850R though, correct?
