I'm a fan of Dynoflash, so I'd vote for Al. I have been able to get good results from both the mail-in-tune and custom flash. But this is the only one that I've had so I can't compare.

[QUOTE=MYEVOVIII]Dynoflash everyone I know with it has had excellent results!
Personally I think that a magazine should invite all the tuners to do their base ECU flash on a BONE stock EVO VIII running 91,92 or 93 octane (take your pick).

Works can put their P2 flash in with boost lines.
Dynoflash can put their base flash on with boost control.
Vishnu can put their XFlash
Turbotrix and Jestr can put in their comprable ECU flashes

Then an independent party can Dyno all of them under identical conditions and monitor A/F, timing, knock, HP/Torque, and whatever else.

This would be awesome if someone did something like this and did a complete article write-up.![/QUOTE

[QUOTE=mygsx]Interestingly, I had the honor recently to write an article on reflashing for Turbo magaizne

I think the concept is a multi part series where they look at all types of cars

They selected one flasher for each kind of car - e.g. Hondata for Honda, Dyno Flash for Evo, Ecutek for STI -, Something for SRT-4, etc etc etc

Then they picked the brains of all the flashers and did tests on stock cars and cars with just stage one kits

Its an interesting article - I think it will be out in Feb '06 issue or March '06 issue

BTW - Thanks guys for your support and good reviews


Which ever flash tuner you choose, (there are many good ones) - I just wanted to point out that when I started my company doing this I was a hobbiest like yourselves and my goal was to turn the modification and tuning business upside down. When I started only a few shops offered flashes - generic standard ones for $599 for a MAIL IN FLASH !!!!!!!!

I called it Dyno Flash as we originally wanted to tune each and every car on the dyno every time. As I started flash tuning evos every day, I foun out that dynos all read differently and it becomes very difficult to get good results on strange dynos without a lot of experience on individual dynos themselves.

We started out doing the flashes at the same $599 price - but instead of a base flash I gave you a dyno session and a custom tune all included at the same price

With the advent of more tuning experience on evos and with better equipment, I was able to acutally get better results tuning on the road and cut out the dyno fees

I saw a way through volume sales to TRAVEL to someone's town, hook up equipment, custom tune thier car and spend 2 hours with them for under $400 !

Talk about getting what you pay for!

The mail in flash - optimized to match YOUR individiual mods for $199 was another ground setting development and a lot of others have jumped on the band wagon to copy our price point and concept. I originally was able to offer it becuase I was tuning so many custom tuned evos that I had a lot of base maps and in time I was a library of hundreds of base maps for almost every evo mod combo a customer could dream up.

Honestly, when i started, knowing that base through the mail tunes are by their very nature approximations which yield a modest improvment and limited power compared to a full custom tune, I could not understand how people could pay $599 for such a product. I was amazed when these same shops claimed that custom tuning was not needed and that the only proper way to tune was with a "one size fits all " master tune which fits all cars.

In any event - I set the $199 price for the mail in tune as I thought that was a resonable price for about 20 whp gains. i could have charged more, but I felt it was a reasonable price considering what it was.

Thus far I have sold well over 2,000 flashed ecus and the reliability record has proven to be amazing. Thus far, there have been zero tuning related engine failures of which we have heard and just many propblem free happy users.

So long as demand is available to organize custom tuning trips across the USA - that remains the best way to get the most power, safely and in a very cost effective manner. At about $350 - $400 for the flash itself, custom tuned, including all tuning time and travel expenses, I think its a decent value. I have more customers in the 11 second time club and now the 10 second time club than any other flash tuner and the results speak for themselves.

As the flashing market continues to become flooded with more and more "new kids on the block" - I just hope that some of the people out there will remember that in flashing, like in many things in life, experience and practice makes perfect.

 

As with all measuring device, a baseline is 1st established. From there, anything better is an improvement and vice versa, on THAT particular dyno.

 

This is true

If your goal is simply to maximize whp on a particular dyno then by all means then all you need to do is manipulate the settings in the tuning tool of choice till you make the most whp output

HOWEVER, what I am talking about is how to get the car to run well on the ROAD and I have seen that many dynos do not accurately repliacte real world conditions

(The mustang dyno is a rare exception)

Meaning that a correction factor must be applied in the tuning to accomidate for the diferential between the dyno used and how the car will run on an acutual road

For example - on the home Dyno Jet dyno I use, I know exactly which a/f , boost and coolant temps to use to have it accurate to how the car will run on the road. This is done by trial and error and experience and one of the reasons I am not a big fan of tuning on strange dynos.

I have had a lot of sucess on the Mustang dynos and I have found that they are generally really accurate. However, you still need to keep in mind that the air flow on a dyno is a small fraction of what it is on the road. Keeping this in mind, plenty of colling time is needed between pulls on a dyno.

This is the reason why for example Ferrari tunes its F1 engines on an engine dyno INSIDE a wind tunnel

 

 

before i tuned i modded my car with full bolt on's

 

I just bought an 03 and it already has a 3 inch header back exhaust, im buying next week a mbc,680cc injectors,malbro 255, header, headgasket, and i want to boost it to 23psi. (this may be a dumb question) but what is the purpose of the computer flash? and is it required for this boost? Anything helps. Thanks

 

I have a 2003 evo 8 with a 2.3 stroker, stock ecu, stock turbo on 25 psi, 1000cc injectors, and a few other things.
I need to retune it completely does anyone reccomend the evoscan? if not which ones do you recomend.

 

ECUflash and EVOscan are great for tuning. If you need help with a tune, give me a PM,email or call.

 

Thank you so much! I think I'm going to go with EVOscan. Right now I am rebuilding the top end but once I complete that I will be ready to tune it so if I run into any problems I'll be sure tho contact you. And thanks again
