Probably too much of a bother. I think we can handle posting them ourselves. I will scan mine up later today as soon as I figure out this stupid scanner.

 

One would hope the requests of the customers were not "a bother"...

 

Zeus,

I don't want to post what some customers might consider their private info -- I'd rather leave that up to them. After all, they paid for the dyno time and they paid for the P2, the decision should be theirs and I choose to respect that.

David, you have expressed why you don't post your own dynos to me already... the comment was a poorly worded reply to the gentleman above. Point was that Works has not thus far considered their customers "a bother".

 

Thanks for the clarification, Zeus. I see your point.

Incidentally, I have not forgotten about your fuel pump/injectors question and will address this when I have a chance to confirm my response with our engineers (now at SEMA).

Here we go. We will post them here:

Hi David and everyone. I just got my Evo last week and this is my first post.

Sorry to revive an old thread, but this just caught my eye. Is 8,000 rpm really a safe redline for these engines? I would like some extra power (300+ hp would be nice ) but don't want to shorten the life of my engine.

Also, can the stock clutch withstand these power figures? I remember reading that it was barely adequate for the stock power output.

Thanks!

More power you add no matter what is going to shorten the life of an engine. Life of the engine with more power is directly related to how often you push your car etc. 8000 rpm is moderately safe, but I believe 7850 has been used most commonly as the best for max rpm. Besides your not going to be making any power up that high anyway, so whats the point? Hope this helps.

 

...any word David?

 

Sure. I meant that I don't want to shorten the engine life unduely. It's just that the redline on the tach appears to be around 7000 or so but David mentioned his mod would allow you to hold it up to 8000. I just want to get a sense of how badly this will affect longevity in an otherwise stock engine.

Where does the rev limiter kick in on the stock engine? I'm still breaking mine in (only 650 miles so far!) so I still haven't been able to rev it up.

Emre

 

If you're still breaking it in - don't try to find the redline or rev limiter!

 

Stock rev limit = 7600 rpm
Brain Flash (P1): 7850 rpm
Brain Flash (P2): 7800 rpm

Can you flash back to stock if you ever want to? Also, can the dealer diagnostic equipment tell if the engine has been flashed (or "unflashed" back to stock)?

For example, Turner Motorsports offers the "Shark Injector" for certain BMW's running OBD-II engine management. The unit plugs driectly to the diagnostic port and lets you switch back and forth between stock and re-mapped engine management. Apparently, the switch is invisible to dealer diagnostic equipment, so there are no warranty issues.

I think this question has been answered a couple times. If you ever want to get flashed back to stock - WORKS has that option. If for some reason your reflash would get erased, they can re-flash you (not sure why this would happen).

I'm not sure why you'd ever wanna go back - the P2 I've got makes the car feel SOOO strong.

 

Well, my original question was whether the dealer can tell if the car has been flashed. If the answer is yes, then you'd want to "unflash" the car prior to bringing it in for work to save yourself the warranty headaches. I wouldn't want to have to send my ECU to David each and every time the car goes to the dealer! If there's an easy way to switch back and forth between stock and flashed (like the Turner Shark Injector), then there's no problem even if the dealer diagnostic equipment can detect a flashed ECU.
