Are you flashing both new code and new data into the ECU or just new data (maps)?

 

I guess the answer is that by changing all of the data (maps) in the ECU, we are also changing the way the ECU interprets the data (if that makes sense).

As an example, when you make changes to the air fuel ratio, through the use of a piggy-back air fuel controller (AFC), there should be a corresponding set of adjustments made to the ignition timing maps and boost maps as well as rev limiter, etc.

This way, the ECU knows that when certain conditions occur, in one area, a corresponding set of adjustments occur in other related areas. This is why the line between simply uploading maps and understanding how the ECU interprets this data "coding" becomes a little blurred.

However, it is only through understanding how one set of parameters changes another set of parameters within the ECU that WORKS is able to both extract the maximum reliable power out of the factory ECU, while at the same time maintaining the streeability and balance of the OEM power curve.

It is all too easy to be influenced by published "peak" numbers (and rest assured, our numbers will not disappoint -- after all, we have access to more tuning parameters available to us than can be achieved with piggyback controllers and interceptor boxes) the real issue that EVO enthusiasts should be concerned about is not only peak numbers, but how the power curve looks. Does the boost build in a linear manner? How is the drivability compared to stock? How is the overall balance of the car?

These are the hardest elements of ECU tuning to get 100% right. Finding extra power out of a forced induction engine is easy -- coming up with a comprehensive set of maps that closely mirror the OEM feel of the car and factory drivability / reliability while delivering all that extra power is the hard part.

Keep in mind too, that our ECU tuning needs to account for variances in available octane, variances in climate, and even car-to-car variances. This requires extensive testing in real world conditions to get right. We would never treat our customers as guinea pigs and will only release an ECU tune when we are absolutely confident that it has been thoroughly tested under a wide range of operating conditions similar to how Mitsubishi itself tests its own products before releasing them.

WORKS may be a little slower to market than some of the competing systems out there, but we are firm believers in our approach and are confident that our customers and performance data will show that the Brain reflash is worth the wait.

Ya know your talk is impressive david... your way of describing matters is even more impressive but a while back i asked about regular lancer ecu's being flashed. I wasn't specific enough as you answered that some companies are doing that and your concentrating on evo's... This is almost true about lancer ecu. There are companies flashing the ecu but not on turbo setup. Here is where your knowledge comes in. With so many regular lancers going turbo there is a market for flashing thier ecu's. People like jet, etc. are not willing to do this as they are only working with NA modifications not forced induction. Is there a possibility of you taking the lancers that have gone turbo to the next level by flashing thier ecu's?

 

Boeturbolancer: PM me or shoot me an email at "davidv@worksrally.com" with your phone number.

I'd be happy to talk to you about this project.

If you are only changing data, then ultimately you are constrained by the behavior of the stock ECU's logic. Even if you know the "transfer function" or "truth table" of the stock ECU logic, and can fiddle with numbers in the maps to make it do what you want (with timing as well as fuel, etc.), you are ultimately going to be limited by what the stock ECU "knows how to do" in response to different inputs.

Strictly speaking, it seems that a flash map replacement can never be as powerful as a piggyback computer which can not only change mapped responses but as well, perform its own logic on raw input values, transforming them into desired input values to be seen by the stock ECU logic. Only a piggyback computer (or replacement ECU) can genuinely "upgrade" the engine electronics.

 

Simple answer please for a simple question how much is the ecu upgrade, how much hp dynoed

 

ECU upgrade is $449 (with an additional 10% off on pre-orders). No "official" power numbers have been released, but based on the "unofficial" numbers we are seeing in our final stages of R&D, they will not disappoint.

Works. Is there a estimated time for these figures to make it to the surface. Just curious if its in the next month, in a few months. ..??????

 

Barring any unforeseen delays, we expect to have official dyno figures, as well as to begin shipping out pre-orders, within the next two weeks.

Will you offer an ECU reflash for people with no MODS? Seems like there could be a lot of power to be made with just the reflash. I would like the boost to hold till redline, not taper off like it does now. I would also like some more off-boost ignition timing advance as well. My EVO is such a turd off boost...

 

EVOeight,

Our standard "Brain" reflash for $449 (minus 10% discount for pre-orders) doesn't require any mods. We can extract excellent power, drivability and reliability on a totally stock EVO with our Brain relflash.

-- DavidV

 

Looking forward to it!

 

Could you tell us what the typical turn around time is after an order is placed? Do we need to ship you our ECU first....or do you send us one already re-flashed and we just ship our stock ones back? Maybe a deposit program of some sort?

My car is a daily driver and I would prefer to have my car down the least amount of time possible.

thanks.

 

We do need your stock ECU, but we are offering 24 hour turnaround on the Brain reflashes, with priority overnight shipping (FedEx) on the return as an option. This is why we are encouraging people to pre-order on the Brain reflash. Not only does it get you 10% off on the price, it also allows us to set up an early appointment for pre-orders for even faster turnaround.

At WORKS, we understand that it isn't much good having an EVO in the garage if you can't drive it!
