Re: TPI injector identification (305 or 350) high idle / rich exhaust problem
Hey Guys, Got the EBL P4 installed and its great for my simple needs. So far did about 10 iterations of VE learns and engine has definitely pepped up. Between the new Delphi injectors and running SLP runners and SLP cold air box I think it needed some tuning. One thing it pointed out to me immediately was the TPS sensor. Only opens to 80% or so. Think my carpet is in the way or need to adjust something. probably would have never known without it.

Super easy hardware wise. I bought the one pre-assembled. Only thing that needs done is to insert three connectors into one of the ECM connectors - that is for your USB hookup. The WUD installed with no problem. I had some issues with Tuner Pro, it wouldn't install on a laptop, finally gave up and put everything on another laptop which gave me no problem. Just read his intro to tuning a few times and you'll be set to do a few things in short order. I was an embedded software developer in previous life, so all of the bits, bins and flash was nothing new for me, so not really any learning curve there, but its super easy even if you haven't done it before.
