 First, make sure you are running the latest version of Pegasus. Mine is V2.01.0127 and it's up to date. If yours is any earlier, it's definitely out of date. If out of date, use the Pegasus Update Manager to get the latest version. DO NOT try to update a Gryphon with an old version of Pegasus! Next, set your tune back to Level 0 on your truck and remove the Gryphon. Bring it to your PC and start Pegasus, then, plug the Gryphon in to a USB port. The Gryphon screen should light up (I think mine becomes red?) and you should see your unit's Serial Number (S/N) on the status line in Pegasus. Click on Updates->Gryphon Update Manager. If there is a firmware update, go ahead and install it. DO NOT install a calibration update. That will wipe out your custom tunes. Now, once everything is finished, go back to your truck, turn the key ON and plug the Gryphon back in. You should be able to reprogram your truck to the desired level now. I calculated an unloaded circumference of 2741 for your tires - what you calculated. Using 7% rubber squish (which is close to 3% total squish), I get 2644 as the figure you should enter. This is MUCH larger than the value you were using. Try it. Remember to hit <Enter> to save the new value and then scroll to <Done> to start the programming. If this still doesn't work, something IS wrong with your unit and Bill will have to be the one to help you. - Jack |

I am back at it again with this lol. I installed my 315/70/17 back on and well I have the gryphon at 2880 for tire size. Yet the speedo is off by 4mph again. So what size should I try? I played with it for 30 mins last night and nothing seem to change. I am using my gps to calculate my actual speed. That and when I have it set on 65 cruise control people in the slow lane are passing me. So I do believe the gps is accuarte and the speedo is off still. Any help?

Your Tire Size (TS) is way too large! I'm surprised it's only 4 mph off. A larger circumference makes the PCM think you are moving faster than you really are.
Bill has this neat "Gear Ratio Calculator" in Pegasus that I use for TS. All you have to do is put "315/70-17" (notice the dash in front of 17) into the Old Tire Size box. You will immediately see 2672 mm in the Old Circumference box. Notice the "Squish" bax has a "5" in it. The circumference is being adjusted for a 5% "rubber squish" (what Ford uses). I get better results with 7%, so if you change the "5" to "7", you'll see 2644 mm. Try either of these values, and adjust as necessary. - Jack Last edited by Jackpine; Sat, August 1st, 2009 at 01:29 PM. Reason: Fixed stupid typo |
