Eric, will a J1850 VPW OBD II diagnostic tool read Duramax codes? If so will it display injector balance rates?

Eric, rather than me explain it, check out this website. I am interested in this for my wife's '96 Blazer. http://www.scantool.net

I did get my interface and have used it with the scantool.net software. It does not show injector balance rates. Just basic stuff, MAF data, Engine RPM, Coolant temp, % of engine load, etc. Allows you to read diagnostic codes and reset the MIL or "Check Engine Light". I do believe someone with some programming knowledge could do some tinkering to get it to read them. I think they have a programmers toolkit available to do specialized things such as this.

There is another free software package at http://www.obd-2.com that I am going to download and try. I got this link from someone over at the Turbo Diesel Register website. obd-2.comEdited by: Pick
