ok i think my ecu took a dump on me, but im not sure on how to check it, i got a new map sensors, a new MAF sensors, a new TPS sensor, and 2 new o2 sensors, and they all still throw the check engine light! my a/f guage is running really rich(the last 2 green lights are on and they wont budge anywhere) and there is a thick cloud of black smoke comming out of the tail pipe. anyone has or knows where i can get ahold of a ECU, or whats a good standalone system for a dsm and where i can get it tuned? I know of AEM's that runs for around $1500 but is there any other good standalones out there?.......

I have Lucas 550cc injectors, walbro 255 Fuel Pump, and a S-AFC, still to put on but i dont want to put it on yet if its running rich as hell now. i would like to try to get it ready for the dyno session on the 19th so i wont have to take my crx or my wifes civic turbo. All ideas and help is appriciated. i want to see what kinda numbers to expect after i install the fuel system upgrades and turn up the boost to 15-18 psi.

 

if the car is running rich just turn up the boost!!! and if you need a new ecu call forigner auto computer repair. they are off bush ave i believe. they should have the ecu you need.

 

Dosent sound like an ECU going bad. Not sure without seeing the car and yes the AEM is the way to go.

 

It cant be your ecu being bad if you say that the check engine light is on but then again i am no expert. I would pm BROTHERS or LANCERMAN they are the ones who really know their shit. Also are you running any kind of fuel management? you might want to look into that at least an AFC or something.

 

yeah i have fuel management in the way of an S-AFC, its not installed though. but the car at first was running fine with a bad hesitation. the check engine light said that o2 sensors, map sensor, iat sensor, and maf sensors where bad. so i bought new o2 sensors, and that didnt work, so then i replaced the MAP sensor and it was still there, so i bought a used MAF sensor that was unhacked with all the honeycombs and the bottom screw on the MAF still was there untouched, and it still had the hesitation. so i knew the TPS sensor only had 1 bolt in cause it broke off in the TB. so i did a 1g 60mm TB swap and know it runs rich as hell! i followed the guide on Road race enginerring to do the swap with all the vaccum lines. all the sensors on the 1g TB fit fine on my 2g. but know it runs so rich that it idles a little rough with light black smoke, but when i floor it, it wont rev past 2000 rpms and there is really big puffs of black smoke. and the only thing the check enine light trips is the maf sensor/IAT sensor and Map sensor.

 

You need to get the car on a data logger to see what everything is reading.

 

it defentely is not the ecu ,because first of all THE CAR IS RUNNING. your problem seems to be fin your fuel your getting to much fuel. This is why you have a thick cloud of black smoke behing the car . You need to find out how much fuel presure your runnin, it might be your fuel pressure regulator. but check how much pressure is coming off of the line.

 

dsmtuner... do you even have any idea what your talkin about? just because the car is running does not simplify that the ecu isnt bad. ive seen plenty of times where the car runs and has had ecu problems. just for once in your life, stop giving opinions and start doing some research.

My car did the same shit one time and it was a boost leak. My coupler came of the intercooler. Just a thought. Good luck.
