Anyone know of a company that makes a simple ecu upgrade chip or piggyback computer that will allow the evo to hold 19 psi all the way to redline instead of backing the boost off at higher rpm?

Not true ... Worksrally reflash keeps stock boost. RMR has the reflash that uses the stock boost solenoid to hold boost to redline; however, I heard that they holding off on selling these for a few weeks until they iron the glitches out (to my understanding they had problems with boost).

Dude, your safest and best bet is investing in a boost controller ... I can fully recommend the HKS EVC , but it's not cheap. If you wanna go cheaper, then I would suggest a manual boost controller.

 

That's not what DavidV at Works says...allow me to quote him...

Sounds to me like they are able to up the boost at redline with their reflashed ECU...I guess DavidV can settle this one way or the other.

This is from this thread: https://www.evolutionm.net/forums/sh...5&pagenumber=5

 

DavidV at Works has said alot of things over the past few months. We expect it from him just as we would from any other marketing rep.

Can the boost map be modified through ECU remapping? Absolutely. Does Works ECU reflash include this modified boost MAP? That would appear to require further investigative research for independent confirmation.

A word of advice, seek independent confirmation from multiple sources in your quest to validate any vendor's claim.

You should also consider what your long term modification plans are and acquire your parts accordingly. I am not a fan of reflashing because unless you can do it yourself, you have to pay again each time you add another mod to the car.

Until such time that economical user reprogrammable reflash capabilities become available, I'm sticking with my Vishnu XEDE piggyback which provides sufficient programming capabilities to accomodate any mod I anticipate.

 

To clarify: Peak boost remains unchanged with the WORKS Brain flash. However, boost is sustained differently, while still attempting to closely mirror the stock power delivery curve. What this means in practice is that the car feels and drives like stock, but pulls just that much harder.

Another point: WORKS does not insist that our customers only use our products or state that every mod requires a reflash. While we offer a reflash to optimize each of our WORKS engine performance upgrades to ensure that our customers get the full performance of the hardware they purchase from us, this does not mean that each mod that one puts on his/her Evo requires a Brain flash.

Further, while we can only provide performance assurances with our own products, engine performance products that are substantially similar to those offered by WORKS have been shown to work well with the WORKS Brain flash.

Lastly, WORKS provides a complimentary reflash to each of our customers for WORKS engine performance upgrades. So, a customer gets a flash for whatever engine hardware is purchased from WORKS at the time they order the Brain flash, and he/she is also entitled to a free reflash for any additional WORKS engine performance upgrades purchased – be it 1 week later or 6 months later.

The whole works reflash sounds fishy to me. I would rather go with name brand performance parts from Greddy or HKS. Tuning with a Afc II has been no problem. I can't see the advantage of a flashed ecu. It seems like it would limit you more than anything. Besides, who wants to run stock boost? With my BLitz Boost controller, I'm running 20 psi all through the gears with no problems. Not trying to bad mouth Works, but I don't think flashing the ecu is the best option. Just my 2 cents.

 

According to Techtom, the US importer of the ECU flashing tool that most companies are using, the current crop of reflashed ECUs does not change boost control parameters in the EVO 8. They are currently trying to figure out why this is the case since this problem does not appear in EVO 7 applications. Needless to say, there is more code digging that needs to be done before full engine control is available.

Just my 2c

Word.

 

I don't smell what's fishy. Tuning with an AFC on controlls the A/F ratios where an ECU reflash will also control timing and other parameters. That's one big advantage right there. Now the limitation thing is there, BUT it all depends on a persons future goals and needs. Not everyone out there wants an Evo pushing 20+psi and putting down 400HP. Some, like myself, just want an easy, one time, no hassle modification that won't likely be detected by your dealer (voiding warranty) and increases power by a significant amount.

 

Whether you use a Mac or Snap-On 1/2" wrench, you're still turning the same nut. The brand doesn't change which maps are available through the ECU or how they are altered.

Shiv,

In time you will no doubt come across many EVOs with various setups and ECU Reflashes on your dyno and datalogging instruments. That is where the facts will show up.

 

In what manner is "boost sustained differently"? What does this mean?

 

Interpret it as you will. 21st. century snake oil

 

n00dle,

Believe what you want. The WORKS Brain flash certainly isn't for everyone, and I take great pains to identify which customers are well served by this approach, and which are better off going another route (i.e. full standalone). Believe it or not, this is one pf the reasons we have not yet implemented online purchasing on our website: I want to have as much contact with potential customers as possible to ensure that they are appropriate candidates for the Brain flash.

That said, your participation in this thread is fairly one-sided to say the least. Keep telling yourself what you want to believe, and let others enjoy the ability to choose the right product for them.

Also, FWIW, here is a comment from a customer this morning:

"Again, I am very pleased with your product. I have not made any comments yet on the web boards because I don't want anybody knowing I have it. Word gets around where I live ... . Also of note, I ran 2/10ths faster than [another EVO] in the quarter. He has cam gears, boost controller, and a afc. I was very pleased."

For more feedback on the WORKS "snakeoil," please feel free to search the board and get the opinions of those who have actually used the product.

Thank you and drive through!
