I hope that with regular oil changes and track abuse I'll not encounter this issue before a lot of miles ... ! |

No flashing to stock with ecutek retains licience but it unlocks ecu. Other systems like oft,tactrix, brzefit can then write to ecu, but if you use other system to write, then that will overwrite the embedded ecutek licience in ecu and its lost, as the other systems dont re write the licience code. As long as you continue to use ecutek to write the licience is retained, you can flash thousands of times, whetever tune you like |

The only time ive seen a tune be a problem with vvt activation is if base idle speed is set to over about 1000 rpm. The ecu want to see a series of conditions for about 60 seconds to initilise vvt, zero throttle idle less than about 1000 , vvt phasors at zero , likely oil or coolant tems at some level and possibly others. But ive heard of guys with rearly high base idle having trouble |

Quick question also when I had the OFT I would frequently clear my check engine code (p2096) since I run catless headers, the car would always have that typical dead pedal sequence for a few fays. Since it's doing that dead pedal sequence everytime after clearing codes, doesn't that count also "flashing" the ecu again? Shouldnt the cams have misbehaved back with the OFT when I did that the code clearing since the ecu is re-learning again? Or do they only misbehave when you flash a new tune with different cams settings while clogged?

You are implying the sluggish throttle is caused by vvt not enabling but we Don t know for sure yet without proof (= logs)
Also, Are you pressing very slowly the accel pedal for 3 or 4 times with the ignition on and engine off before cranking the engine after reflash or DTC clearing? It helps a lot About learning, csg Mike Is right, Ltft learning plays a big role in engine smoothness and pedal response In my tune i keep ltft disabled all the time and basically in less than 5 minutes of driving my pedal goes ok |

The licience always stays in ecu You cannot recover a licence by flashing to stock it still stays in ecu Hoever if you did purchase any used working ecu that contained an valid ecutek licience you can then install it in your car and reflash it using ecutek to required calid for your car |

No you dont , licience is totally independant of cable used Tune files supplied by tuner are keyed to cable dongle id ( and possibly vin) but the licience in ecu is npt keyed to a cable kit. Any ecutek cable can reflash an ecu with an ecutek licience. But cavle kits are designated to groups of vehicles so you would need a cavle kit assigned to a brz\86 vehicle type See here http://www.ft86club.com/forums/showthread.php?t=117520 |

So I dont have any logs but while data logging my tuner has said it was for sure the cams not responding well and was very sure and that he has ran into this problem with other cars 86s hes tuned. He said the seafoam through the oil helped the other cars but seafoam procedure had zero affect on my issues getting better. Mine was very weird because mine happened so instantatisly after the first flash it went from the car being perfect to driving terrible. Sorry if I dont explain this correctly for I'm not too educated in this subject enough, but if I remember clearly he said he was giving the cams a certain amount of retard and they would end up doing something completely different from what he set them at. Sorry if that was a bad explanation but I'm sure that's what he said.

We would really need a datalog to discuss this
If he tells you that cams don t follow well the target it s different from saying cams Don t activate, because if you say so then the vvt is enabled I saw some cars where the cams struggle a bit to follow the tune's target, or like jump to 50 when you command 40, or a discrepancy of 2-3 degrees sometimes, but those cars still run well and the owners Don t complain |
