Hydra ECU Questions.

[RaCeR4LiFe022]

Does anyone know if this ecu will do all functions.. and possibly allow us to get a turbo or better s/c numbers?

[rawdizzle]

"It controls all systems required to make the engine operate."


This system is strictly engine tunning. None of your accesories features etc normally controlled by the ecu will function. This is a bare bones system designed to tune and run the engine not make your ac function .

if thats your thing then go for it.

Similar to an SDS system as well (simple digital systems)

^^^ i likey already! lol anymore info?

[rawdizzle]

"any more info"

sure
Hydra- The hydra is a full stand alone form of EM. This means that it does not use or require the stock ECU. It controls all systems required to make the engine operate. This is both a blessing and a fault. It means that you have absolute control at all times. However if you do need to pass an OBD-II scan for your annual inspection you will not be able to do so with the Hydra in place.
In order to make a car run well with a full stand alone like this you need to map out how the ECU acts in all situations. This means that you must design the compensations for all temperature ranges, altitudes, cold start, bad gas, extra load, and anything else that may change the way the car runs.
The hydra is MAP based instead of MAF based. This means all the internal tables are setup based on the boost pressure and temperature currently flowing through the intake manifold, and not by the mass of the air flow. This eliminates the need to have MAF sensors that read larger flow rates, or to trick the MAF sensor into reading less air mass than there really is. This is a good feature for high HP cars, but requires retuning any time the efficiency of the system is changes. That means anytime you change any component on the car you run the risk of requiring a retune.
Additionally right now the Hydra is hindered by a cumbersome interface. Although it is a pretty interface, the ability to make global changes to a map currently does not exist. Currently you are required to make changes to each load site one at a time. New firmware is all that is required to improve this issue.

alright ur my favorite... i learned alot.. lol but the problem is if i keep adding mods for my car ill have to tune it. this thing will b difficult

[rawdizzle]

I see your list of mods in your sig. You need to get the Hondata reflash. Dont worry about stand alone ecu's until it is fully compatable for our cars. The HONDATA ecu is hands down the BEST investment youll make.

What are you planning on doing to your car to require extensive tunning . please elaborate. - Joe

[RaCeR4LiFe022]

IMO: i just wanna do some sort of forced induction that puts out more than 50 hp to the wheels and 30 tq.. Dont get me wrong.. i have nothin against hondata.. and the reflash is real nice but if im gonna do s/c then itll have to b reflashed =\

[rawdizzle]

f - sc'ing .. Im a die hard turbo fan - less prone to heat soak, detonation, easier to get more power, (higher the boost as opposed to changing a pulley) better top end, etc.

lookin for some nice and nasty power. nx (nitrous express) wet kit. Ive always run NOS before my turbo days. Its really hard to beat the cost effectiveness of NOS , especially if you want a nice low buck kick in the butt.. And dont listen to all the hype that nitrous will blow your motor. Installation is 1 when doing nitrous setups.

Fun fact
Nitrous was used first in WWII in fighter planes.

[RaCeR4LiFe022]

lol ik love the fun fact.. anyways... i cant turbo without the ecu.. thats why im lookin forward to it =]

[rawdizzle]

turbo setup that "should work" taking things back to the ole school and dirty.

Turbo
manifold
wastegate
bov
piping
sds eic (simple digital systems extra injector controller) OR FMU
larger fuel pump
intercooler
forget the name but the map sensor adapter.(ill get it - give me a min to update)

tunning Apexi AFC - with AFC hack.



Thoughts anyone?

[RaCeR4LiFe022]

i heard that runnin a turbo on the apexi is unsafe...

[rawdizzle]

your not running the turbo at all.

your piggybacking your ecu to change your injector pulsing. At preset rpm intervals. basically a poor mans standalone.

the car will run like this and keep your oem ecu functional.

Its just not a High HP setup. 400+ whp at that level you need standalone and datalogging etc.

[RaCeR4LiFe022]

hmm all i gotta say is try it lol tell me how it goes =].. i wanna make the tsx quick =] the engine has potential.. the ecu doesnt lol
how sick would it be to have a TURBO-boosted tsx.. i can just imagine

[rawdizzle]

im loving my na setup right now. I had a boosted b18b1 ek civic - its the love of my life to date. but man was it a money pit

Id rather have granite countertops than a turbo right now lol
