my sx is sluggish

[SonOfAnarchy ZA]

as most of you guys know i just put a jap import into my sx but it is jerky and seriously low on power cant even put off in 2nd gear. could it be possible than the car needs to be dynod and re mapped?

[djtreble]

If there is anything other than stock on the car in the engine bay then yes it will need a tune and a map, depending on what management you are running. This will also be the reason for the smoke.

Have you got the butterfly system connected to a vacuum source?

[Daniel]

If you are running the standard ECU then please get the idea of remapping out of your head.
Mapping around a problem isnt going to help you anything.

You have a boost leak somewhere.
Disconnect the butterfly stuff completely.
If you have a standard ecu check for fault codes.

What Daniel said.

When i got my car it was also sluggish, The best thing to do is check online how to self diagnose your ecu and what the codes represent (located at the passenger side) turn the screw and it will start giving you codes.

My problems where, Tps, Water temp sensor, knock sensor.

Another problem was that my timing was way to slow! Seems like my pulley 's timing marks are off.After i had that sorter it was 100's again! Just make sure you know what your are doing when you adjust the timing, detonation is a KILLER!!!!!

[Daniel]

Heres the manual: http://www.silviansw.com/manuals/s13_manual.zip

I had forgotten about timing, that will affect it as well

[SonOfAnarchy ZA]

Im screwed wats butterfly system and how will i see fault codes. Is there anyone that will be able to help me im stupid with most of this stuff

[NIZAN-R]

ca18det had 2 types of heads
4 port (stock local sa car)
8 port Import

a 4 port car does not have the needed valves to work the butterflys in the intake of a 8 port intake

butterflys will need to be modded to stay open

Lol Jason, you see the link to the manual above? Download the manual and have a look through it.
Its realy very easy to use.

but anyway...

How to check for fault codes.

The ECCS Control is found under the passenger side kick panel.
The ECU has a window on one side to view a red LED and a green LED - when checking fault codes, a red flash is worth 10, and a green flash is worth 1. So for example, the code to say that everything is functioning normally would be 5 red flashes and 5 green flashes - the code is 55.

The ECU has 5 modes of operation, for diagnostics codes, it has to be set to mode 3.

1. Make sure the screw next to the viewing window is turned clockwise.
2. Turn the ignition on
3. Both LEDs with flash once, then a pause, then a second time, then a pause, etc. etc. up to 5 times then will repeat the process. After is has flashed 3 times then turn the screw completely anti-clockwise. - this will select mode 3.
4. The LEDs will now flash codes. 55 means that everything is normal. The rest are written below.
5. When finished, turn the screw back to clockwise and the ECU will reset itself automatically.

Don't worry about the '5th cylinder misfire' and '6th cylinder misfire' or anything, the codes are the same for all Nissans.

Jap engines come with butterfly valves in the intake runners. It has a little actuator on the plenum at the rear where the vac lines attach. As long as you dont have anything connected to the actuator then your fine.

ok found a site thaat tells me how to read my errors so will try it out
http://www.ka24development.com/ecu_codes.html

[SonOfAnarchy ZA]

thanks dan will let you know what errors it throws up

[SonOfAnarchy ZA]

checked my ecu got 11 cas error and 34 knock sensor i reset my ecu took it for a good spin checked again then i just got error 34 knock sensor. my sx struggles to get to 6000rmp it takes for ever and boosts on 0.6 consistantly but no power what so ever from 1000rmp up

[Grobblere]

Then it's in limp mode due to the knock sensor, i have a friend who has a couple of knock sensors for the Ca18's

Ill ask him how much he wants for 1

[Daniel]

Limp mode isnt a huge performance hit though, just runs rich. Definately not what you describe.
The knock sensor sits in the block underneath the intake plenum. Its a round green plug with a shielded cable. Maybe its not plugged in? or the cable broke? Do a continuity test on the cable. I'm not sure if the sensor can be tested.



The knock sensor is basically useless on the CA, personally I'd just bin it. If you want to go that route then you would need to wire a 1M ohm resistor between pin 23 and ground.

Have you checked your timing? How did you check your timing? where did you get your pickup from?
I connect a plug lead between the coil and spark plug and then set the Ignition timing to 15 degrees BTDC and is the 2nd mark on the crank pulley from the right.
Some people get their pickup from the white induction wire on the coil pack loom, now I cant remember the details here anymore...but I think if you use a certain type of timing light it only "reads half" so you would have to set the timing to 30 degrees to get it on a real 15 degrees.... anyway best not to use that method in anycase.

[Daniel]

Also you said you put in a jap engine, was the timing belt replaced? If so will you bet your life it isnt a tooth out?
I always count the teeth between marks 10 times as Im mega paranoid about getting it wrong.
