gpfarrell Posted March 30, 2013 Report Share Posted March 30, 2013 Im trying to load my Stage 4+ from the MyCal to my push button start MKS. After pushing and holding the start button long enough for the gauges to sweep, I get this error: "Could not initialize communications with vehicle (1). Check connections and try again" So I've done that, but keep getting snagged in the same place. I think my connections are good... It's pulling the cars VIN number and earlier I was doing 0-60 runs and it seemed to be communicating just fine. Any ideas? I'm dying to try this thing!

12sho Posted March 30, 2013 Report Share Posted March 30, 2013 Make sure the engine light is lit on the start button. Quote Link to comment Share on other sites More sharing options...
gpfarrell Posted March 30, 2013 Author Report Share Posted March 30, 2013 I'll try again and double check that. Any other ideas? Quote Link to comment Share on other sites More sharing options...
Motohead Posted March 30, 2013 Report Share Posted March 30, 2013 my device came with 2 obdII cables if yours did also try the other one Quote Link to comment Share on other sites More sharing options...
Leadfoot Posted March 31, 2013 Report Share Posted March 31, 2013 On my 13 I had to hit the start button twice to get into "run" mode. Quote Link to comment Share on other sites More sharing options...
gpfarrell Posted March 31, 2013 Author Report Share Posted March 31, 2013 My engine light on my Start button is lit, but it still won't work. Thanks for the ideas, please keep them coming! Quote Link to comment Share on other sites More sharing options...
larrylu Posted March 31, 2013 Report Share Posted March 31, 2013 Two things I learned to look for. If you got two cables the one you need is the one with the molded blocky lump built into it. I got that wrong the first time. You must hold the start button in (without stepping on the brake) for several seconds before releasing it. That makes a really big difference and is absolutely mandatory. If you are doing both of those things and its still not working, I don't know what else to advise but call Rick. Good luck Quote Link to comment Share on other sites More sharing options...
gpfarrell Posted March 31, 2013 Author Report Share Posted March 31, 2013 Happy Easter! My molded blocky lump cable was still in the box! Headed to the garage now... You guys rock... Thanks Motohead & Larrylu! Quote Link to comment Share on other sites More sharing options...
gpfarrell Posted March 31, 2013 Author Report Share Posted March 31, 2013 Looking good... It's saving my stock calibration now... Looking like it might be a fast ride to church on Easter Sunday! Quote Link to comment Share on other sites More sharing options...
gpfarrell Posted March 31, 2013 Author Report Share Posted March 31, 2013 Early today, I needed 5.44 based on an average of 4 runs, 2 each in opposite directions. Now I need 4.73 figured the same way. Oh, and the 5.44 was on on fumes and the 4.73 had a full tank of 93... probably 100 lbs of fuel! If I can do this... with this Forum's help... anybody can!

mjhpadi Posted March 31, 2013 Report Share Posted March 31, 2013 So have you had it out and do you like the difference? Quote Link to comment Share on other sites More sharing options...

I'm assuming your numbers are referring to a 0 to 60 test. If so they are really useful to me. I'm going through a test and evaluate period now where I'm going back to stock to figure out why my car is not performing as expected. For convenience my yardstick comparison test is my 0 to 60 times. The best time I've gotten with 1/4 tank and torque loading the tranny is 5.4 and that's running LMS 4+. So I figure it's easier to find what's holding me back while stock. I don't have a stock 0 to 60 yet so thank you for sharing yours. Quote Link to comment Share on other sites More sharing options...
gpfarrell Posted March 31, 2013 Author Report Share Posted March 31, 2013 Larrylu, yes those are 0-60 times... My private test track doesn't have enough room for 100 mph 1/4 mile blasts! If your "track" is slightly uphill, your times will be slower. I ran both ways on mine to compensate for Pennsylvania. Also, if the car creeps a few inches while you are holding it with the brake, the clock starts and your times will quickly be a few tenths longer. Tuned, my brakes have a hard time keeping the car dead stopped. Stock, it would old still until you let off the brake. Good luck, and thanks again for the help.

larrylu Posted March 31, 2013 Report Share Posted March 31, 2013 I wish I had a private test track. I don't think the grade was an issue but your suggestion to check the creeping might be. Think I did creep just a tiny bit before launch. I remember hearing the brakes groan a bit. I will retest before detuning. Thanks for a very good suggestion.

brucelinc Posted March 31, 2013 Report Share Posted March 31, 2013 Glad you got it loaded, gpfarrell! We needed another tuned MKS on this forum. I presume you are pleased with the results of the tune. For what it is worth, I thought mine improved after 150 miles or so - especially transmission operation. It became smoother while still being firm. For what it's worth, I hit a snag the first time I tried to load my tune. I frantically PM'ed Mark and before he had a chance to answer, I tried it again and it worked fine. Quote Link to comment Share on other sites More sharing options...
brucelinc Posted April 4, 2013 Report Share Posted April 4, 2013 GPfarrell, where the heck are you - in jail for street racing? :RpS_smile: How do you like the tune? Quote Link to comment Share on other sites More sharing options...
