 I talked with Hydra yesterday and they expect a PnP system to be ready the middle of Oct that uses the stock ECU in parallel to control A/C and gauges (as others have already mentioned). |

A few questions regarding the Hydra that maybe someone can answer...
If an '05 Elise has traction control, will the Hydra eliminate it? If so, does the Hydra have the ability to do traction/launch control? Thanks!

Power FC is a good idea mainly because of 4 things: 1 - price (under $700 these days) 2 - Ease of tuneability (the Celica GTS one is all set up to run a 2ZZ) 3 - availability of resources (theres a ton of info on tuning them and some really great enduser created basemaps floating around out there nowadays. It makes starting off with a new tune MUCH easier) 4 - Its a proven system - we've been using them on Celicas since 2003 if I recall - there are many daily driven NA and turbo cars running them with no problems at all. mind you none of this takes away from the value of a Hydra for FI applications - speed density (MAP tuning) makes tuning a boosted car WAY easier and the hydra has a bunch of other cool options available for it as well. It just costs twice as much as a Power FC and theres not much info out there on tuning a 2ZZ with one installed just yet. |

Actually, VA is moving to a OBD2 check for smog.
http://www.deq.state.va.us/mobile/mobobd.html "On Board Diagnosis II (OBD II) Inspection - Most 1996 and newer model year vehicles will be subject to a new computerized analyzer check that will look for fault codes that may be present in the vehicle's on board computer. This inspection may be performed instead of the dynamometer or two speed idle test on eligible vehicles. Visit OBD II inspections for more information."

I just wired up another car today, so far so good. I'll be final tuning it on Monday and will report back.

Stand alones
I've just been reading over this, and I don't think there's anything special about the Hydra that lets it run the Lotus engine. As a professional tuner and a dealer for many major brands, I find the Hydra cumbersome and limited in tunability. I have quite a bit of experience as I have 2 STI customers with them, and they both go like stink with 22 and 25psi respectively. But it does work.
However, if you can setup the Hydra in parallel with the stock ECU to keep the gauge cluster and OBD-II, you can run many other systems. Its just wiring really. I have been disappointed with the EMANAGE and cars making 12psi+, and I spent quite some time messing with it. I know there are other people who are running it and say its acceptable. I think there are better products in the same price range as the Hydra available. I would be interested in seeing how other ECUs work in parallel with the stock ECU. Has anyone tried this?

The Emanage lack of success led us to what other options there were. The answer was few and far between: Unichip, and Vishnu. Unichip has been updated to deal with some issues, Not much known about Vishnu. The learning in the Lotus ecu can be eliminated to help the piggybacks stay in control. Not much really understood about how this is done. Other stand alones were just the Forcedfed at over $6300.00 (?) originally. The Hydra showed us a possible solution. At least someone came up with something for us. It is relatively affordable, being around 2k. We keep our gauges. And VERY IMPORTANTLT, it's plug and play. If you want to uninstall it and go back to stock or sell the car, it's simple. No one on this board, other than Hass, has personally tuned one yet. It hasn't been on the Lotus long enough to know the pluses and minuses. I did raise a question in a post if anyone had experience from the Hydra on other cars. Their website seems to indicate the Subarus use the Hydra somewhat. I have talked to the owner of Hydra and he is working with me in some capacity to make a plug and play for the '06 now. I called him yesterday to help identify the plugs. It's a start. He personally has a 2005 Lotus with the Hydra on it. That definitely means something to me. He has a full-time car to develop the '05 system with. The Hydra has several unused outputs. He said, for instance, that one of those could very easily be used to display knock threshold with a light or whatever. The Hydras for other cars have a wideband option. Likely for the Lotus also. The knock monitoring and wideband both appeal to mepersonally. I'm not trying to sell or represent the Hydra. Nothing was available in a plug and play for '06. He was interested in helping. John at Forcefed got nowhere with Unichip. No plug and play, they wouldn't work with him. I tried with Unichip and was referred to Forced's parent company. I welcome other choices, I think everyone does. Perhaps if you're interested in making something, you might want to ask what people would want to spend and what they would want for features. My criteria: plug and play interfaces with Lotus dash Knock sensor active and relatively tuneable (Emanage bypassed the sensor) mass airflow eliminated-ok wideband option would be desirable. program installed to run a stock Lotus switchable between on or more maps cam and lift control I have traction control but don't need it decent rev limiter a few inputs and outputs would be nice knock sensor and a/f ratio monitoring without a pc would be a nice bonus. |
