Engine cut out

Evo TME · Feb 10, 2008, 07:04 AM

please help

i drive an evo 6 tommi makinen edition and im worried that somethings wrong with my engine

the car shuts off for a split second when i punch the throttle to the max and noticed that when ever my boost gauge reaches 20 psi the car shuts off for a split second with a big bang sound, iv been told that since my car is entirely stock the ecu cant handle 20 psi and since its winter the psi runs higher and reprogramming the ecu should solve the problem. it only happens when the psi reads 20 and cuts out the engine as a safety procaution i have been told....

any idea what might be causing this cut out???

cheers

That's fuel cut because your boost has exceeded the "safe" limit as programmed into your computer. You need to remove the fuel cut via reprogramming your ECU somehow (not the same as for 7s/8s/9s). The ECU+ is an amazing piece of equipment, but the only way to get rid of that is to:
A. lower your boost
B. Get a standalone (like AEM EMS)
C. somehow flash your ecu to get rid of that.

nothing too technical, it can be done useing ECuflash, very simple.

you are getting a fuel cut when ur boost esceeds a predetermined value. feels like the car is dead!

so ANNOYING!

nothing too technical u got a MBC or EBC?

nope dont even know what a MBC or EBC is but for the help guys really appreciate it....i guess i just need to somehow change the ECU or reprogram it

u have a manual or electronic boost controller?

is the car stock? what mods u got?

its all stock, all i have is a turbo timer and a boost gauge not that its related to this

hmm weird ,,just turn down ur boost slightly as i said above when ur boost is too high the ecu reads it and cuts fuel...car seems dead..

if u lift off the throttle for a second and then go back on the throttle u will get back power,, that is until it happens again..

this does not happen everytime u go X to board (WOT) right? only sometimes?

PM me if u want further info i can help.

its alright i think i got the answer i was looking for, as long as theres nothing damaged that results in this cut its cool with me

thanks for the help guys really appreciate it...the weather is getting hot again so i dont have to worry about my boost levels hitting 20 cuz its gona be too damn hot although feeling that kind of power felt real good
