Is there a way to tell on a used Evo, If the ecu has been flashed?

 

is it real fast?

 

get a friend to follow you on the highway and do a pull, if your friend sees black smoke then probably not.

 

Well I quess is it fast is all relative... Its ok.... I'm in the process of rebuilding it. I purchased it after it had been involded in a small crash to the right front door. I am planing on setting it up for road corse. I know someone who has an 03' evo that has the dynoflash done. He ran in the same class as I with my Porsche. He is awsome taking off , but slow at higher speeds. He told me that it was because his was flashed for the drag strip.

 

there are a few ways to tell.. for starters.. do you have a boost guage installed?? if so, what are your readings at?? If your at like 18-19 and only dropping 1 or 2 psi after being in full throttle then your deff flashed... if your boost drops to 15ish psi then your not flashed..

the comment about the black smoke not being tuned is INCORRECT... you'll still have chances of BLOW BY oil such as I do myself under high boost release into vac. I am getting a oil catch can to fix the prob, but its not a way to judge being flashed or not. Mostly these flashes are fixing your boost level from fading and also no boost cut/fuel cut and also will raise your Rpm in certain flashes.

 

hook up an A/F meter to your car (or on a dyno) and see what it says. If it's lean, then you're definitely flashed, unless you are tuning it out yourself with an AFC. Also, if your revs aren't limited at stock level, and like 4rcd6 said your boost also. Those are the main things that people flash for... I'm flashed and I'll occasionally get black smoke on a heavy acceleration even though I'm leaned (11.x afr), so that's not a good barometer...

 

A dealer can tell you, or one of the shops that does reflashes should also be able to tell. All other methods are not reliable, IMO.

if your car goes past 7000k rpm then your flashed.

 

7400 Rpm is the stock rev limit while 7800RPM is rev limit with flash. Also you will hit boost cut off if you don't have a flash and you are pushing 22/23 PSI at redline. It happen to me

Where in NC are you located?

 

usually not a good idea to ask a dealer to see if you ECU has been tampered with... they will instantly not cover anything on your car.. they cover nothin as is.... thats just a death sentence if you ask a moronic question to a dealer... THey will also give you incorrect info on the ecu as it is.. they'll say 1 flash is all it can handle before needing to purchase a new one.. RETARDS!

 

All depends on the dealership, I suppose. I haven't had any issues with mine. You could always mail the ECU to someone like Vishnu or TurboTrix and pay them to check it out.
