[QUOTE="99cobraUgotbit, post: 11763338, member: 18423"] Slicks!!!!! I have 3.73 with 275/60/15 MT DR. I have a bad issue with the 1-2 shift because of the boiling point of the DOT3 clutch fluid boils during burn out and gets too hot while launching, here's what Shaun told me You're slipping the clutch in order to launch on DR's (this is the proper strategy for DR launches), however your technique is over heating the clutch, which transfers that heat thru the Slave cylinder, resulting in the in-ability of the Slave to release the clutch completely (due to the boiled clutch fluid in the slave), which in turn results in a missed gear. The ECU monitors crankshaft RPM and compares it to Transmission input shaft RPM (technically output shaft RPM vs trans gear), so it knows when the clutch is slipping, building up heat, etc.* The ECU is activating clutch protection in your AED tune.* It doesn't do it on the Bama tune because Clutch protection was not implemented in the HYZ6 strategy.* (techincally it's there, just doesn't do much)* When the 2011's started coming back to dealers for Clutch/flywheel replacements, Ford got VERY aggressive with the Clutch Protection strategy. I can remove clutch protection from your tune, however this will NOT solve the missed gear problem as it is a function of your launch technique on DR's, which as I stated earlier is the CORRECT way to net great 60's on DR's. If you wish to continue to run DR's and slip the clutch at the track, you will eventually need a transmission rebuild (worn syncros) as well as a clutch.* This is precisely the reason I run slicks and 'drop the hammer' rather than slip the clutch at the track. If you'd like this modification done to the tune I will send you an update, just realize it will not solve the root problem, in fact it could make it worse.* (more clutch slippage = more heat) [/QUOTE]
