Getting fuel cut, help please!

[Abe'sGST]

Ok, so I got my gst 2 months ago and it came with a few mods. Every time I give it some gas at about 4500 rpm's i get fuel cut, and it smells straight up like gas, so i'm sure its running rich. It has an apexi SAFC and in settings its set on 0 on both low and high throttle. I want to fix this and what i would like is to remove the SAFC but i talked to the previous owner and he said it wouldn't run right if i did that. Is that true? If it is what would be the best settings for it? help please!

no not yet man, i didn't have a chance today, got off work till 10, but ill try to check tomorrow morning

do u think thats what is causing mu fuel cut? whats the best thread in here that will help me recirculate it?

No that is not what is causing your problem. You WILL NOT be able to recirculate that bov

 

[Abe'sGST]

yea he told me i wasnt going to be able to, is the 1g bov the only one i can recirculate?

This is how my bov is on right now, its hooked up into the pipe from my intake ...how would i recirculate a new one?

OP, you need to figure out if the injectors are stock. Look at the part number on them.

If they have a blue top, look for the part number INP-009. It should say B450L on the other side. If they have a black top, look for the part number INP-018 and it should say MDL450 on the other side. If either of those are true, then you have stock 450cc injectors. If they are not stock, you'll need to use the SAFC to get the car to run right.

What other mods, that you know of, have been done to the car?

ok i took out all my injectors this morning before i went to work and they are stock, since they have a black top with INP-018 and MDL450 on the other side

Because adding more boost will fix the problem.

-Do a boost leak test and fix any leaks.
-ID your injectors so you can set the SAFC correctly.
-Loop the hose from your pressure source to your wastegate directly. This makes it so you run the minimum amount of boost that you can.
-Get everything else on working correctly.
-Then maybe it would be an acceptable time to install the boost controller.


EDIT: It looks like there's a j-pipe in the background of your one photo. The stock turbo wouldn't have that. So somewhere along the line, someone put a different turbo on. Now you need to ID the turbo too. Look on the compressor cover.

You need to get the number off the flat area show in the upper left hand side. It will be probably be one of these:

14B
49178-01010
49178-01030
49178-01400
49178-01410

Small 16G
49178-01520
49178-05200

Big 16G
49178-01420

Evo I Big 16G
49178-01450

Evo II Big 16G
49178-01460

Evo III Big 16G
49178-01470

I also took a look at my turbo and it is the same thing as the one in your picture, so I'm guessing that's the stock turbo

The one in the photo isn't the stock turbo on a 2g, but it is on the 1g. You should be fine zeroing out the SAFC since the injectors are stock.

Try resetting your ecu. Take a terminal off the battery for a minute before putting it back on. Also reset it after you do your boost leak check and all the leaks fixed.

o really? thats kool, the guy had told me it was stock when i bought it but i guess not..where should i put the high and low throttle point on the safc?...also i took off the mbc, if i decide to put it on and bring up the boost, whats the highest while the engine still being safe?

Earlier i was looking for more leaks and found one, the weird thing is that it sometimes has vacuum and sometimes it doesn't..it leaks from where i have my index finger, it comes with a little cap on it but with the cap it still leaks? what is it and is it supposed to be hooked anywhere?

does anyone know what it is and what its for?

hello guys?
