tjss2005 Posted November 17, 2006 Report Share Posted November 17, 2006 Just put the procharger on 3 weeks ago. It ran extremelly well until a couple of days ago it threw a (crank position variation not learned) code. What does this mean and can it become a serious problem?

rivierakid55 Posted November 17, 2006 Report Share Posted November 17, 2006 i dont have a procharger but my truck just threw that code a month or so after installing a nelson tune. no driveability problems at all. just did the crank relearn.

tjss2005 Posted November 17, 2006 Author Report Share Posted November 17, 2006 How do I go about doing a crank relearn? Can i just clear the code? Quote Link to comment Share on other sites More sharing options...
rivierakid55 Posted November 17, 2006 Report Share Posted November 17, 2006 to my knowledge no. i believe that you start the truck and stab the throttle to or over 4000 rpms a couple of times and that is the relearn. there should be someone on here who knows for sure though Quote Link to comment Share on other sites More sharing options...
Bowtie70SS Posted November 18, 2006 Report Share Posted November 18, 2006 You need to have HPtuners or a tuning program to do it youself...the dealer man charges around $50 for it. Maybe you can find a member on here to do it for you...I'd do it for free and I live in Ohio, where are you? Dave Quote Link to comment Share on other sites More sharing options...
tjss2005 Posted November 18, 2006 Author Report Share Posted November 18, 2006 I appreciate the offer Dave but i've got hp tuners myself but just haven't messed with it enough yet to know how to do it. I'm goin to school in kalamazoo right now but I'm from the Detroit area. You think you could post a walk through on how to do it? - thanks tj Quote Link to comment Share on other sites More sharing options...
Bowtie70SS Posted November 18, 2006 Report Share Posted November 18, 2006 You need to use the data logger.Start the engine put the parking brake on and hold the brake pedal down then open it up and connect to the PCM. Click on the engine icon and it will open up the engine control menu. Click on the relearn tab and it will walk you thru it...I need to run out and grab my lap top to explain exactly. Also I'm sure it is on the HPtuners forum. It only takes about 30 seconds to do Dave Quote Link to comment Share on other sites More sharing options...
