ecu flash

[Beak]

Has anyone learned how to flach the ECU? (w/o disconnecting the battery for 12 hours)

What would be the benefits of flashing the ECU?

im sure you know that the ecu is the computer for the car that basicaly contolls everything; as you drive the car the ecu records and adjusts the car preformance according to how the car is driven; when you flash the ecu ts like having a fresh computer to learn driving patterns; so if you want to rag on the car and drive real agressive then the computer adjusts the car to this manner of driving. say you want to baby the car and have good gas milage then the ecu would adjust to that style of driving. ect....

oh I know what and ECU is and does... I don't know why you would want to "erase it" and start from scratch. Why re-invent the wheel. On my racebike, I have what they call a power commander. I have a onboard computer that brings up the configuration to the computer. From there, I can manipulate it, ie.. adjust fuel, air etc. right on the bike! When I'm done I send it back to the ECU and WHAM!..it takes affect and I can tell from the throttle response if I need to adjust it more. They have that already for cars already but you need to hook your laptop to it..

I think he's talking about getting it altered. Like a piggy back system to get rid of the speed limiter and increase the fuel/air to get more power. I haven't heard of anything for our car but who knows...

There is already one in the works... some techno company... its already been posted and discussed... not for a CVT engine though...

There would be no point in "clearing" the memory on the ECU for it to "re-learn" your driving style. The computer is constantly adjusting to how you drive. Dont' believe me? Find a car/truck with an auto 4/5 speed trans. do a couple runs with the pedal to the floor (from a dead stop), you'll most likely notice that the transmission starts to shift harder and faster the more hard take offs you do, it will downshift sooner too.

You cant "hot-swap" an intake and exhaust onto a car and expect the ECU to "adapt"... i dont think it works that way...

Its nice to flash it before taking it to the dealer; this way when they plug it in to their computer it does not show that you ragged the fukk out of it... many reasons to flash it; people do it all the time.

your car won't even pass inspection unless it has had 70+ miles put on it since the last time it was reset. Not to mention, its not like the tech pulls the car into his bay and the ECU jumps out of the car and screams out "Guess what HE was doing!!!!!!" The computer learns to change according to driving style. A tech hooks to it to check for error codes and make sure all systems are responding correctly. I don't think they could see a shift point or fuel curve or anything of that sort, thats factory level programing

LongBeachCoupe: Think of it like the car has a learning curve. its always learning. If the sensors report to the computer that for the past 5 WOT commands, that there has been more air rushing past the MAF sensor, then the ECU will require the engine to recieve more fuel to keep the O2 sensors happy and reporting the right air/fuel mixture

The power commander on a bike is slightly different, it is needed because their is no MAF sensor on a bike. I also have one on my R1 and can adjust using my laptop. A similar setup on a car, like seen in most of the import car movies, would caost you like $3000, where the power commander 3 and quickshift kit for my bike cost me about under $500.

I've spoke with Technosquare in SoCal. They will be looking for a donor car pretty soon. If all goes well I'll be back in SoCal next month, and hope to have a Borla on her by then, as well as the Injen short ram that UPS just delivered about 30 minutes ago; so I may be willing to be a donor for them to do their magic.

This was their response to me:It is in our agenda to work on your application, but we are currently working on the development of 350Z and G coupe right now.We will be also looking for some test vehicles locally for R&D on new model cars.
