I sent my ECU off to DynoFlash last week to have the mail order reflash done. Well, it has helped more than what I was expecting. To begin with, I have installed a 3" turbo back system along with a cat to keep it legal and clean, but none the less, I got that irritating CEL anyway. I cannot begin to explain how a CEL was bugging the **** out of me as the car is only 2 months old. I was thinking that the richness that is programed into the stock ECU above 5000 rpm may have something to do with the CEL as the cat cannot keep up with the extra gas flow associated with the larger system, so that would be a possible gain from the reflash other than the obvious. Besides that, as the weather has began to cool, I have been hitting the air/fuel cut programed into the ECU from the factory. Also I wanted that extra HP, increased spoolup, RPM raised, top speed cut removed ect, ect. I recieved the ECU in a very quick manner to when I sent it out, and then I installed it. Now it spools up fast enough to scare the **** out of my girlfriend when taking a corner as the car now goes into a four wheel drift!! The power just does not stop coming, it keeps that hard acceleration to wherever the RPM cut is (I have not hit the cutoff and have shifted as high as 7700 RPM. The ONLY reason I shifted was from looking at the tach, there is no drop off in pull.) Besides that, the temp here in Texas dropped to 40 degree's last night, and the fuel/air cut is GONE!! Not once did the fun come to a jaring, petrifing halt! (Once you hit the cutoff you will know what I am talking about). Then, on top of that, after about 30 miles, the CEL turned off! I guess the flash cleaned up the exhaust stream enough to the point that the cat can do what it is supposed to and clean up the exhaust. Mind you, this is not the custom tune, I can only imagine what that would do for the car! As you can tell, I am pretty happy with the reflash. I would actually recomend the Stage Rev flash to anyone running the Xede as it would get rid of the air/fuel cut (I have seen on the site where some Xede users are hitting it already), and it will raise the RMP cut off along with the top speed cut. This is in no way to bag on the Xede as I will probably add one in the future so as to have access to all other paramaters so as to tune for other modifications in the future, but bang for the buck the Stage Rev reflash kicks some serious butt!!!

 

I did not realize the CEL was able to reset itself "on the fly" so to speak. I was under the impression that a thrown code was maintained until ECU was reset by power disruption, or scan tool. Maybe that is only for certain codes.

 

After I put the computer in I drove home (left the car at parents house where all of the tools are) and the CEL was on. Got up next morning went to work, CEL on. Went to lunch with G/F and some friends, CEL on. Started car and left parking lot after lunch, CEL gone. I had to do a double take to make sure that it wasn't there, and then I pulled over to shut the car off and back on again to make sure that it wasn't something stupid like the CEL bulb burning out or something, but when I turned the key over it came on until the cart was started and turned off!

 

get a pocket logger

Your first mistake was letting Al touch your ECU though hahaha

 

stupid comment

 

lol why? I feel bad foreveryone that is letting Al touch their ecu =P

 

I agree with SuperchargedGTZ, what Al did to my ECU has given me much more then what I thought I was paying for to begin with. In that case, why wouldn't I want him to tune my ECU? I see this tune as a great starting point for whatever modification I aim to do in the future. (I really am lying to impress my friends Mitsubishi) This reflash has actually FIXED other problems I was having!

By the way, I recently read the reasoning behind the horribly rich tune Mitsu puts out from the factory. According to US EPA regulations, a cars catalytic converter has to last for a given amount of time for a car sold in the US. Heat kills catalytic converters. Throwing a lot of gas into the combustion chamber kills heat. Throwing a lot of fuel into the combustion chamber also kills your gas consumption, kills your HP, and just so happens to kill the environment with the pollution that our pig rich cars are shooting out the tail pipes. But it is better to have a catalytic converter that works for x amount of time at the expense of massive amounts of pollution then it is to have a cat last 5/6's of the length of time that the EPA wants it to but keeps everything clean while doing it. And this is not Mitubishi's decision, I would think that they would like to advertise better HP #'s along with better gas mileage to boot, the EPA puts up these stupid restrictions. Pretty dumb if you ask me. I believe this because like I said earlier, when my car was leaned out the CEL went off and no more 0420...catalyst efficiency below threshold..... Now with the clean exhaust the cat works perfectly.

 

OMG this better not be another BASH AL post or i'll SCREEEEM! Congrats on the flash... another happy Customer!

What are you doing goigin in the turns hot and going WOT? How are you scaring your g/f?

 

Was this the $79 flash?

 

Thanks Joey!! Glad it works ! It makes me really happy to hear good reports from our through the mail customers !!!

You know - I must be really scaring ole' Shivvy boy with my very good working and low priced reflashing options ! Imagine his alarm - no more overcharging and inflated profits!!! I better send out my entire internet posse to warn everyone that anyone who has a reflash done by anyone other than the great Shiv will wind up with a blown engine and all sorts of troubles. (Even though the great Shiv is the only one who manipulates the knock sensor signal )


I greatly appologize to my clients that they must endure these constant and frequently renewed idiotic SMEAR attacks from members of the Vishnu camp.

The facts are that we have serviced over over 100 Evos already without any incident of any problem, complaint or adverse situation.

I choose NOT to follow the practice of negative attacks on Shiv; making personal attacks and making false warnings on his products. I feel that my satisfied customers are the best form of promotion about my services. I have nothing bad to say about Vishnu other than I feel my appraoch to tuning is superior and a better value.

We offer the following options - through the mail:

$79.99 base Stage Rev - changes your rev limit to 7800 - removes the fuel cut - makes your factory boost stop tapering - ( a great value)

$225.00 Mail Flash - Stage Rev plus a mild 91; 92 or 93 octane fuel and ign timing tune - typical gains are 10 - 12 whp over stock

Custom reflash - $275.00 individulaized attention and custom modifications to alter your base maps to suit your needs - eg bigger injectors; cams etc - - then use a SAFC or other piggy back to fine tune it

 

Al **** i never even asked you this but what did you do to my fuel cut ? How much can you boost now stock? Just curious.

 

Is there anything you can do for elevation with your reflash? I live in Denver (5600 ft). And I believe this causes my EVO to run even richer. I am currently using an HKS FCD. I heard this was not too good. Can you guys help me? My mods are listed below.

 

All the reflahes got a fuel cut raise which increases the threshold for boost cut onset by a very signifciant factor - you need about 400 whp to hit it as set

We now have recieved some new code changes from Tec Tom which are supposed to compeletely eliminate the fuel cut 100%

We still have not decided if a compelte elimination is adviseable or not

It may be prudent to retain some boost cut to prevent against a boost controller failure , etc .?

We ill be testing the new code and then prob be installing it upon customer request on very high hp applications

 

Please shoot me an email or call me at (203) 515-4110 and we can discuss some options for your situation

DO NOT use the HKS FCD under any circumstances !
