Cant pass 50-55 mph/?? Whyyy! HELPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP PPPP

alright so i've been trying to figure this out for a while now .

i bought this ca18det from someone who fried there wireharness and fried the ecu

i bought another ecu and got the harness re wired. i finished setting up the car and have been test driving it.

the car will not exceede 50-55 mph and when i reach those speed the car basically stops and alot of smoke comes out of the exaust for about 5 seconds the smoke is a white to blue color. i see smoke come from the turbo flange too. sometimes the car will stall out aswell when i try to exceede it. the car catches anything under those speed in all gears

possibly bad maf? or ecu?

ANY input will help.

I don't think it has anything to do with your speed, maybe just load on the engine? How fast can you go in 4th gear? 3rd? White smoke would indicate that you are burning coolant, can you verify this? Could be a blown seal in the turbo or a blown head gasket, although you would have serious problems before you got up to 50mph.

I know my buddy had a similar issue one time coming back from a drift event. The car wouldn't boost at all and wouldn't go over 55mph. Turns out there was a vacuum hose not connected to the bottom of the intake manifold. Check there, I don't know if it's the same problem, but it's worth a shot.

it doesnt matter what gear i am in once im at 50-55 mph it will do it , i can be in 4th at 3100 rpm and it will do it as if im in 5tg at 2500 rpm then it will do it

check ecu for codes

Your car is afraid to speed on the highway, just tell it to sack up!

honestly I couldn't tell you I'm trying to get my idle good here but I'd start with the simple stuff you would possibly over look, codes, leaks, double check the wiring? could be a paint but you never know

[Nibras]

im not getting any codes , wiring is all good , and lol you're a clown Nyt

[steve shadows]

Have you done a vacuum leak check yet?
