The First Run...Codes

[dumbo]

Just took her for the first run. Runs AWESOME...will do a log in the morning.

but from a roll in second at about 2000rpm hit the gas, pulls, kinda hickups and check engine comes on, then goes away car still feels awesome.

get home check codes, get, 14,Ignition Signal, 24,Intake Air Temp, 34,Abnormal Turbo Charger Pressure.


soo i dont know how to check 14(i've checked tsrm..please indulge me) i also have timing control hooked up with maft pro and have to cut IGf and IGt-maybe thats it?
24 is because of my maft pro-speed density
34 i'm kinda of clueless, i guess its when you have to high of psi(but its a 57trim from driftmotion, dunno why the wastegate wouldn't be working)


thanks guys...and man forced induction:evil2:

The hicup is fuel cut, your pulling to much boost to quickly the ECU is seeing airflow numbers it doesn't like at lower rpms. I would think your having boost spikes due to the boost controller not being set up correctly.

Code 14 means the ECU isn't getting the IGF signal from the ignitor that it has fired.

i dont have the boost controller hooked up,

i never thought about fuel cut, but i dont understand why it would over boost-its brand new, maybe i'll double check the hose to the wg actuator

so how do i fix code 14, is it a problem?

Code14 - Check the wiring from the ignitor to the coils and the coils themself. You might want to ensure the ignitor is properly grounded per this thread:

Code 34 - Very likely due to a boost leak. Check your IC piping/connectors from the turbo, to IC, to the TB. The connector between the 3000 pipe and TB often cracks. Also check the accordion hose for cracks/leaks.

thanks again jdub, i'll be doing that this afternoon. as for code 34 i use a map sensor-speed/density-so would a boost leak still cause this?, and have no accordian just a tube and a filter off my turbo,except one port for isc feed, and one for pcv "suction" all my tubes and couplers are new-maybe i missed i'll double check that also.

Ahhh...missed you were running speed density. I do know the MAFT Pro emulates the AFM signal for speed density, but I don't know what effect it has on fuel cut. In any case, a boost leak will cause problems...worth checking. The code 34 may be a left over...have you reset the ECU to clear old codes?

ya i reset the codes before hand, and i saw the check engine light come on for a few seconds. but i'm gonna reset them again after i do the igniter ground and go for a lap around the block and log a run and post it up, see what happens. did a quick look for leaks but nothing too obvious.

ok reset the codes, did a couple laps aroudn the block, only code 24 and then i did the igniter ground and the idle seemed solid and the car ran awesome pulls strong no fuel cut, but kinda leaned out when starting to boost, but i could only get about 3/4 throttle cause i'm waiting on the 'proper' throttle linkage, heres the run please indulge me


ohh stock 02 is connected
