How good is the Hydra built-in boost controller?
I have a DTEC that i'm looking to sell, but i'll hang on to it if the one in the Hydra is lacking. Can anyone comment on it?
I'm curious if it helps the tuner to have it integrated with the software. I'm also curious if it supports dual solenoids - one feature that really attracted me to the Dtec. any help would be greatly appreciated...

A great combination is a Prodrive boost solenoid and the Hydra. I never adjust my boost, so the Hydra boost controller works fine with the upgraded solenoid. The newer Hydra's have gear-controlled boost like the DTEC. |

The thing that I like about Hydra controlled boost control is the fact that there is IAT compensation. The Dtec (which I used with my factory ECU) doesnt have this which causes lots of over shooting when its cold out.

Something to be aware of is the fact that the Hydra has only 1 boost map.
There is no switchable boost mapping like there is for fuel and spark. This is worth mentioning because if you run (for instance) water/meth injection and tune in more boost while it's activated, you will need some way to drop the boost down to "normal gas" levels if the WI system fails (or if you're out of water/meth...). The only way you can do this is with an external boost controller setup with Low/High settings. |

There's no need to tune for both. The timing and fuel changes do not take effect unless the WI system is working. So if it's not working, you are left with your normal pump gas settings.
You are not, however, left with your normal boost map. So, yes, if you have your laptop with you and are in the position to pull over and tweak your boost configuration if you have a problem with the WI setup which will not resolve itself... by all means go for it. There are plenty of times where that is not the case. Like say... in the middle of lap 3 somewhere... or... when your tank runs out on a road trip. IMO, if you (whoever) have to bring your laptop with you everywhere you go... "In case" then your setup needs some serious work. |

My solution to the boost map problem was to by an eBoost2. That way I can just change up my boost settings on the fly. It is an extra cost, and a little more complexity in a setup, but it really adds a lot to a system (I think, of course I haven't finished my Hydramist install and the eBoost2 will be added after that, so my opinion is based on my thoughts not experiences).

I like the simplicity of the prodrive setup - stealth for sure and no clutter. I'm just curious how well that thing can regulate 25+ psi boost. i've used both the Blitz SBCID and the EBoost in the past and really liked both of them. I have a DTEC now, but I may get rid of it since many tuners seem to despise it. |

You can have the Hydramist system restort to wastegate boost also. If your wg spring is stiff enough this will work well. For instance I usually run a 18 to 20 psi wg spring so when the Hydramist system is inactive it can drop boost to this level and when active whatever the Hydra system is tuned for.

^^^ thanks. When using Hydra's with an aftermarket boost controller like the eboost, are all of the hydra's fancy internal boost control features overridden?

Is this how my setup is? I know you haven't had a ton of time to get small things like the WG spring to be setup right since my overall water injection has been finicky. |

I had everything working perfectly but due to the rush I wasn't able to "tidy" things up myself and I know there were some bugs after other hands went back in. We'll see what can get done on the next trip Thanks, Phil www.elementtuning.com |
