This doesn't necessarily say that one is better.

Some cars have more knock than others on the dyno so more fine-tuning is necessary. It could be simply a matter of a bad batch of gas in a car's tank.

Edit: grammar

 

This dyno stuff is rediculous. there are guys that dyno their cars on 100 octane and don't tell anyone that and post those results as well. I still think available torque, driveability, power under the curve, lack of detonation, and good AFR's are key...All of these Works has in spades, and so, I'll stay with them.

Some 'flashes' don't need tuning. Therego, they are easier for those that do not know how, or do not want it.

Are they 'optimized', probably not. Is it safer - depends on the tuner.

 

ahh.... the drama that is the "Tuner War"....

ps-- dynoflash rules

 

All your comments up to this point have been incorrect. You stated that the P2 made similar power to the XEDE which isn't the case. You also are using the custom tunability that the XEDE (or any user-tunable system) provides as a con. Pulling 20-30 additional wheel hp out of car for $200 worth of dyno time (even for someone who hasn't tuned one before as illustrated) is a big fact to ignore.

 

An enginerring degre is great but a sales pitch an results can be just as good. I want a dynoflash. Cheap and works. Unless the others can give something better for the price or make up for it with other features (warranty, more power) for get it. If you can pick two girls that are a 9 and one costs 3 times to get which you going to chose?

 

I did not make myself clear on the tq issue. But bottom line is you will get close to as much tq with Shivs tuning and significantly more whp. This my tq numbers equals my whp on the Works p2 is great but if Shivs tuning produced lower whp #s guess what it would likely be closer to the tq numbers. If you want to compete with the higher Hp cars get the Exedes with a race gas map and when you drive around town cruise with the pump gas map. You have the best of both worlds. bTW Works and Dynoflash are great alternatives but if you want the best for your Evo let Shiv be the Doctor. However don't steal his Pradas or he might forget how to tune.

 

with my dynoflash, yes my boost holds it does NOT taper off at all. i'm holding 24.6lbs on stock 16g

 

Actually, no they haven't. I don't know where you get the 20-30whp #.

I'm talking about a <b>difference in 5whp in a completely stock vs stock </b>car running xede vs P2. I was there, to see the plots, trust me.

I'm not putting either down - and not trying to talk either one up. Rather, trying to explain the differences and pros for each.

 

Happy w/ P2. Fast, solid and no issues. At the time I bought it it was the only "flash" that controlled boost and still allowed ECU to overide for saftey. I could't afford and didn't feel I knew enough to go exede but definately plan do so in the future. Also at the time I purchased the p2 there was to much bs. surrounding the "other" flash to feel good about getting involved.
From this forum I have arrived at the following conclusions:

If you don't want to f with it and want a good solid street tune I was impressed by the P2. They control boost via larger restrictor pill.

Vish is all about the exede. They have convinced me this system has the most flexible tuning options while keeping all the saftey features of the stock ECU in the background. I think the "x-flash" was developed so they didn't get creamed buisness wise, strategicaly priced between works and dynoflash. Nevever tried it, no doubt great product. It's my understanding they can now control boost via code alone.

Dynoflash has come a long way, although the blind enthusiasim for this product I find annoying. I was turned off mainly just from reading this forum. Just me, can't comment on actual performance. I believe this flash can also control boost w/ code albeit diff. from vish.

 

At that dyno day, I put down 10 more hp with the P2 than the guy with an exede. All four are good alternatives. Dynoflash = Cheap, Exede = user tunable, XFlash & Works = Well developed plug and play

 

 

My other post was deleted so I will be more civil with this one. Hagakure, the points you made about drivability,afrs,tq,power under the curve is good but the other options(tuners products) also offer those qualities and maybe a lil more power. Had the p2 with goodies and it is a great product but IMHO a lil conservative for my taste. No dyno tuning or street tuning leaves alot of power on the table and Works doesn't offer that option. With the exedes you can download different maps with your computer and can run a race gas map if needed. FWIW Ricardon does not like Shiv so you newbes that read this can discount any opinions he has about Shiv's products. He states that he has empiracal evidence or has driven all and knows which is best is total BS. My last post was a little more of a diatribe so I guess deleteing it was a good thing. Sorry evom.

 

I just ran across this picture of a car with the XFlash installed. It looks like it uses a boost bleeder tube that completely bypasses the stock boost solenoid. This seems like a cheap 5$ hack and leads me to believe that the Xflash cannot control boost if the boost solenoid has been completely removed from the loop. I'm also sure that one look at this by a Mitsu tech wouldn't be to healthy for your warranty. Good luck with this guys.

 

You are probably right about the power issue, but I'm sold on the engineering approach, as well as the business culture, and my car has plenty of power and torque for use on track days, which is becoming my primary focus for the car. I'll never drag race it, don't see the point in any way whatsoever, and I like the responsiveness and feel of the car. Each to his own, and that's another good effect of the strong and varied aftermarket for this car. Concerning the power, it gets to be overkill, for me at least, at some point. A 340 HP Evo is enough. Ostensibly with the right driver (which would not be me) the car can do high 12 second 1/4 mile times, and get to 60 in under 4.8 seconds with a hard launch...fast enough. I'll never build a high HP monster. The only other things I will do to this car will be to add Water injection for safety, change the clutch (works CK2 is going in next weekend), add Ohlins Coilover setup when my driving skills are good enough to exploit them on the track, and add a cage when I step up the frequency and level of my track involvement. Also will probably get 17X9 wheels so I can run 255's. Power wise, I'm happy. Peace!
