FIRST EVO IX TUNED WITH SAFC2......21psi.....pump gas

The stock ECU however will determine load by how much Hz (AIR) is going into the engine. Since your altering that signal the ECU will then adjust timing to a lower load point. You can make good numbers up top but down low the numbers are no very impressive.

Missing the last 1/3
Where the lower Hz results in the ecu running in the lower load areas of the ignition map and then using the overly advanced timing of that area
The result is knock - then the ecu pulls the timing which leaves you with the low timing or zero timing in the mid range
Hardly an optimal way to set things up
My flash tunes on 91 octane are tuned to avoid knock 100% and not pull any timing on the fuel used. While this may yield less power than a single dyno run done with a safc, the more conservative tuning results in a smoother and safer power band.
There are no absolutes in tuning - mostly compromise and trade off.
In any event - all discussions of SFC vs. Flash from the Evo VIII are now mute as the IX has taken the factory ecu in a direction which renders the safc outdated and obsolite
PS - as to the comments above - a ecutek flash licsense costs a ecutek dealer more than a SAFC

I really do not want to dwell on the subject here
As with most things, time will tell

Second, this thread is marginal in the first place since TT is not a vendor on this site so all the people propping them are only moving this thread closer to deletion. It's okay for them to post the thread about the car but if it becomes a "sell" then the thread will be removed since they do not pay to advertise on this site.

I think you're reading things a little wrong, and please correct me if I'm wrong.
1) This started out as a purely informational thread about the IX, not TT or their tuning ability.
2) After people cam out with negative comments about "the numbers" (par for the course on this board a la the WR) some of us vouched for the fact TT knows what they're doing, not to sell them in anyway. If you want that, go to SoCalEvo.net.
3) Once again, Al demonstates his inability to refrain from badmouthing, however apparently that's tolerated since he is a vendor. If that's true, tell you what...I'll pay to advertise here strictly for the purpose of that privilege.
4) Why does almost every thread devolve into a pissing/groaning/I know more than you/your tuning abilities suck/your tuning equipment or device sucks? I'd say there are some usual suspects here (Shiv, DB, and Al, although not always their fault...they are provoked). THAT is a problem.
Anyway, I still think the question with the IX is how will it handle cams? Or will cams even be compatable with MIVEC? BTW, props to Precision Dyno for not throwing mud. Some vendors could learn a lesson or three.
Actually cams on the intake side will do almost nothing. Also I don't think they will be cheap if they are produced. It would be interesting to see the effect on the exhaust side.
I wouldn't go larger than 272 if that but much more lift like on the revolver, piper cam profiles advertised.

If anybody is trying to make a "sale", like our supposed supermod says, its Al. He goes into threads to bash a product just to make his product look better. If anything, that should be grounds for instant banning.

Hey, lets change the name of this thread so no one accidentally stumbles across it thinking it would actually contain any useful information.
I think "Tuners being unprofessional and acting like children" or "SAFC vs. Reflash, The final battle" would be an excellent title.
Please Please delete this steaming pile of crap this thread has turned into.

ok, since this thread is now completly useless (we don't have the original post anymore) and all we have now is just a bunch of arguing and a big pissing match, this thread is now closed.
it is just a shame that this forum can't even have a single thread without flaming, pissing and *****ing and that most threads end up locked.
