So I was playin with a 240sx last night, around mid 4th gear it hit boost/fuel cut, its happened a couple times since i had the car, it would go into "limp mode" and all i had to do was disconect/reconect the ECU and it was fine but this time that wasnt the case, i checked ALL the pipeing, everything looks fine... its feels like there is a boost leak ( wont go past 2lbs, but again everything looks fine..... I dissconect the battery and ECU this morning right after I got to work...........any ideas.....?


V/R,
Daniel



EDIT : see post #9 & 15 please....

 

n/m ppl.........I guess i wasnt paying enought attention since i was running late and didnt see that my cold pipe popped off...........


thanks...
Dan

 

carry-on

 

the moral of the story is: keep an eye on sneaky 240sx drivers that pull your cold pipes off

 

^ ^ ^ ...

 

hahaha

 

btw I think i preferred Dan over Daniel. I can't see you as Daniel, it cracks me up saying it

 

 

Wow almost 4 months since this happen ( only "problem" ive ever had with the car ).....

So im driving normal this morning, light turns green, I go normally and no boost, i thought it happen again with one of the pipes coming off but that wasnt it, reset the ecu, nothing, thought maybe my MBC went bad so i hooked the stock controller back up, nothing...

Car is "driveable" but it wont go into boost at all, im home now and letting it cool down so i can take off the intake and see if i can move the compressor wheel, hopefully it moves which means the turbo ISNT seized.........any one have any input...?.....

 

so i check everything again and rechecked all piping/clamps/hoses/couplers.....no boost, took of the intake to see if i could touch the compressor wheel to see if i could route it with my finger but theres a solid extension that points up on the turbo that i cant get off so i cant get to the compressor wheel to see if i can rotate the wheel............idk...

 

check all vacuum lines

 

Is your car throwing any codes (Service Engine Soon, Check Engine, etc.)?

What mods do you have?

 

Check engine but thats cause of my test pipe...

AMS fmic/intake/UICP/test pipe/exhaust

EcuTek reflash through AMS

Buschur LICP

Hallman Pro MBC

 

you need to get the codes read to see what other codes its throwing beside the 02 sensor

 

got the codes read, TB position sensor is bad, couldnt get a new sensor without getting a whole new TB, got the TB, TB is on, STILL no boost, got the codes read again, only thing that came up was my cat ( cause i dont have one ) ....idk what to do.....
