Problem with accelleration+ Launch controll
06 STI with Hydra 2.5
Problem is the engine doesent accelerate smoothly when you press on the fuel pedal, what happens is theres a slight delay of about a second then all of a sudden the engine accellerates abruptly , makes it anoying especialy if your racing , and you realy feel it between shifts. Second problem I have is the launch contral on my STI is now not working . Ive entered a value of 4000rpm , saved it to my laptop , then downloaded it to the Hydra ECM, but nothing happens , wont work. I dont think these 2 problems are related, cause my launch control was working fine before I had the Pro Tune done.And the hesitation was always noticable even before I had the Protune. Anyone have any thoughts??

If this is an Element Hydra is the US, email me your map along with your mod list so I can look it over. We do not enable the deceleration fuel cut but instead tune the fuel map to fuel cut as using the decel cut when not tuned properly can make the car have a dead spot. It could also be another problem with installation or mechanical related.
Launch control only works if you purchase the Accessory Wiring Harness from us. Give a call as I'm sure we could work through your problems a lot quicker that way. Thanks, Phil www.elementtuning.com 240.246.0302 |

Wow, that is great service, I'll have to consider the transaction that I just saw here and how quick it was taken care of when I look at a standalone system.

Got your edit to my map Phil, thank you so much for your time.
Unfortunatly the hesitation is still there after your edit, It seemed a little better but sill theres a flat spot when pressing down the fuel pedal between shifts , but alteast the launch control is working again. Il keep searching for the problem, maybe its the TPS sensor. |

I have the same problem with my Hydra, i couldnt fix it, i tried almost everything in the hydra. Throttle response is laggy and hesistating.. Im suspicious about a mechanical problem, cams, valve leak, etc... What mod do you have ? |

RixSTI,
I have never had this problem with an Element Subaru Hydra. I've seen similar things on large TB equipped cars but again never on a Hydra I've tuned, even with a large TB. There are so many different types of hesitation, lean, rich, misfire, throttle delay, fuel cut delay, injector response, that I don't have enough information to really offer much advice that isn't a guess. Running a datalog may shed some light on if it's rich, lean, or knock retard durning your shifts. Thanks, Phil www.elementtuning.com |

My mods are pretty simple :3 inch APS catless turbo back / HKS header / K+N drop in filter / upipe with tiall 38mm EWG / and ofcourse the Hydra with launch control and widband.
Everything works great except for that flat spot between feuling the engine between shifts , Im sure one day il get it resolved , Im not giving up on the Hydra, its a great system , I just need to find in my area with good experience to look at my set up and tune. |

Your map had "decel cut" enabled which can cause that hesitation but I'm pretty sure I disabled that for you when I sent it back but just double check. Also a mechanical issue that can cause that dead spot is the BOV if it's sticking or sprung too softly. Thanks, Phil www.elementtuning.com |

Update on my crises with the Hydra, So far Phil has helped me with the launch control, it is now working fine.
Im still having problems with the acceleration lag or flat spot when accelerating from idle or 0***37; tps to about 10% . I sent Phil proper data loging sample , just waiting for him to check it , and hopefuly help my situation out here. Other than that Im happy with the Hydra and its capabilities .This is a BIG problem that needs to be resolved because it affects the way the engine performs , especially when racing, its almost impossible to race the car at this time. Ive spent 1400$ in tuning costs at Neetronics tuning , and this is the result im left with , I think its definitely unfair. They know about this problem but have not been able to address it. Before sending my car there for tuning they also assured me that they where experienced with tuning the Hydra. So its not like this should have been an issue.

Don't know where this fits in.. I had a different throttle problem
I'd appreciate a response to this, since I have only been driving for a few years now, and know very little about cars.. including my own- 2004 impreza 2.5TS.
When I was accelerating last week, the engine uncontrollably revved up- almost as though the pedal was stuck on the ground. Restarting the car only did the same thing (clutch in, foot off gas, tachometer at redline) I took it in, and the dealer said that the Throttle Control was dirty, and simply cleaning it fixed the revving problem. Is this common? has anyone heard of this? and does simply cleaning it make it all better??? Thanks |

I have also seen someone jam their intercooler pipe in too far literally holding the throttle plate open slightly. Yikes! |

I dug into your map a little more and I may have found some mistakes in there. You have the Accessory Wiring Harness but not all your outputs were setup and I noticed a mistake on your crank triggers which could possibly explain this issue.
I've made the necessary changes to your map so just install it and test it for me. Thanks, Phil www.elementtuning.com |
