S14 SR20 Problem

[Locko]

ok so the swap was done a couple of months ago by a respectable place. I have all new the piping and bov Greddy , the boost gauge etc.. the car is a S14 SR20det 5 speed on a zenki s14. now here comes the problems:
*) the car runs but after a couple of minutes it will start to show on the wide band all the way to 16 (red) at the end and the car from there wont go over 2000Rpm .

Things i have tried.
*) replace maf
**) replace plugs (just in case)

any other idea what can be ?

The car has been driven less than 10 different days and it always had that problem . now the equipment on the car
-Apexi NEo
-AEM fuel/air
-and the rest is just stock sr

any imput would be greatly appreciated

try a different computer iv had a similer prob you have ecu code wc?

 

[Locko]

yep WC

well hopefully is just the ecu.. im really giving up on the car ...

 

[DUDOCIUS]

it should be the ECU...

 

[Locko]

how can i test it ? just get one from another s14 sr and try it ??

Get another wc ecu and try.
Does it happen right away or after it warms up?
Remove the AFC NEO and reconnect wire's back to stock, AFC might be bad.

 

[Locko]

it happens after it warms up , if i turn of the car right away and wait like 10 seconds turn it on again runs good again..

i have a wc ecu running my car if you bring your car up and il swapem over if you wish.
I also have a burnt one that got fucked up when i flooded the car.

thnx man !

Bring your ecu down to my shop and we will put it on my car and see what happens. lmk 561-308-6083

danm that is better lol ill call you tomorrow ! thnx man!

 

[BILLFISHER21]

sounds like the same prob that im having on my ka24det...goodluck let us know what was the prob.

 

[Locko]

well is not the ecu... and thanks bill for the drifting sesion !! ur car is sweet !!! i was great to meet you and thanks for trying to help too bad it wasnt the ecu well back to square one

 

[homeskillet305]

if i was you i'd take off the safc neo and see if it runs better

 

[BILLFISHER21]

try a new coolant temp sensor try another ecu in your car. I have seen the rare occasion where one ecu will run one car but not the other. check maf voltage at the ecu. Moe will help you if not drop it at my shop and il fix it.

from what i read because i also have the same prob with my ka24de(T) is that it could be the cat is clogged up..hopefully my prob is the ecu..goodluck!

took the safc neo off and is the same .. i did notice white smoke comming when you accelerate and as soon as it cuts at 2000 rpm it drops donw the rpms to 800/1000 and white smokes comes up.
