Re: Hydra Nemesis
So it works w/ the auto huh? What is the price and lead time? If I don't get laid off I should have my new motor built in a few months and would need this to get it running proper.

Re: Hydra Nemesis
This is the harness I built. I have already contacted Hydra to ask them to build OBDII harnesses in the future so this adapter will not be needed.

Re: Hydra Nemesis
OK, new update. I am going to be monitoring the stock torque control functions to see when and why it is initiated. From this information, I will be able to write the flat-shift fuel and ignition cut cycles to be initiated using the stock torque control signal from the TCU to initiate it for the Hydra.
Now it is my understanding that the torque control signal is a constant 5v signal from the TCU that is grounded when the TCU wants it to engage. I merely need to confirm this through some tests using a multimeter and a stock car. Once it is confirmed it is merely taking that information and applying it. This should be a help to those who have autos that want to keep them for longer It can also help those who have mt's w/ the secondary clutch switch. These maps can allow you to keep your foot planted on the gas while you shift, w/o shift shocking the engine or the trans and will effectively make your shifts more efficient when racing... More to come Tom |

Re: Hydra Nemesis
Did some more thinking and reading. The ECU has to supply the 5v signal which the TCU grounds when the torque control is active. With that said, I have modified the Hydra harness to add the torque control line into the factory harness. I will test it tomorrow if I find time.

Re: Hydra Nemesis
well I got the torque control working. Cuts 50% fuel cycles when the TCU grounds the torque control circuit. I have datalogged it monitoring the fuel cut% and it is acting as it should. So torque control is all set.

Re: Hydra Nemesis
I was talking with someone about the costs of the Hydra against other leading standalone systems today and felt it would be a good idea to share some information.
Comparable systems like a Utec, Motec, Autronic, AEM, and other seems like a good deal. Many of these systems can be had for less than $1500 USED. New they can cost upwards of $5000. The Hydra Nemesis costs less than $2000 w/o a wideband. Other systems are not built for the SVX harness and would require the assembly of a full engine-ECU harness or a jumper harness that can cost over $500 to build or over $1000 to have one built. These ECU's do not come with base maps and require days of start-up work just to get the engine to run... ringing in at approx $250/hour for a professional to do it means you could spend over $3k just to get the car tuned. The Nemesis comes with base-maps that allow you to do a 20min install and start and drive the car. This also cuts down on tuning time. A good tune should be able to be done in just a couple hours by a professional tuner. Meaning it could cost less than $1k to get the car fully tuned to its maximum potential. There is also the fact that many of these systems have far less resolution for intricate tuning. Many are restricted to a resolution of 12x12 or 16x16. The Hydra uses 32x32 resoltion on ALL 3d maps. This means you can get every point you ever wanted dialed in perfectly. The point I am trying to make it that if you compare sheer cost of the units alone, while some may be cheaper, it will likely cost you more in the long run to get it working. A great example is the Megasquirt. Besides that fact that you will likely need to re-invent your ignition system with seperate coils and plug wires, you will also need to modify the tone wheel and pick-up sensors. Which all cost money. Even if you did all the work yourself the cost of the new sensors, ignition coils, etc... Then there is the task of creating base maps just to get the car running, no less a decent road tune. What it comes down to is this, for less than $2000 you can get a real engine management solution that will plug into your car's stock harness, stock ignition system, stock injectors, and stock sensors and will run the car very well. If you wanted to use another system, it would almost surely cost more and still be inferior in quality and precision in comparison with the Hydra. Compared to ECUtunes software, the Hydra is still a bargain. For $600 you can get a stage 2v7 chip, and a used Z32 MAF. You still need to source your own 370cc injectors which should cost around $500 more if you get rebuilt ones. So that should put you at about $1100 for injectors that are too small to make good power, and the use of a MAF. Now granted, if you are looking to make decent power you will need to upgrade your injectors with the Hydra as well, but you are not limited to a specific size, esp one that small. Not to mention you can use an MAP sensor for a more clear presentation of your engine's actual load. I know a lot of people looking to do some budget builds and this information may help them in their decision on what kind of management to use. Tom Last edited by TomsSVX; 01-06-2009 at 03:02 PM. |

Re: Hydra Nemesis
YT,
Good summary. Question for you. Have you given any thought to an in-dash system that will provide the read outs you get with the Select Monitor, since you can't (??) use the Select Monitor once you go with the Hydra. Thanks. -Bill

Re: Hydra Nemesis
An in-car computer could handle the Hydra software.
About the only thing you would need to make sure is that the Serial port is fully addressable. NOT emulated.
