where will i hit fuel cut?

[Alex Bland]

I was going to orger a MBC and later apexi n1 DP and exhaust. i was woundering how much i could turn up my mbc so i wont hit boostcut. like 10psi? on stock setup

Oki have a big 16g turbo, mbc, fmic, 255 fuel pump and full exhaust (manifold,o2 housing,DP, and catback)in my car and im running about 16-17 psi and i cant even go over half throttle without hitting fuel cut, safc on its way.Do u think that will fix my fuel cut? A little off topic how much vaccum should i be pulling at idle on the boost gauge

You might need the SAFC and some injectors to run that much boost.

You should be between 18-20inHg, like mentioned earlier in the thread, definetely do a boost leak test.

Yeap sounds like another boost leak issue.

I would stay no higher than 15 max on stock fuel and once you buy exhaust and down pipe you will have boost creep like a mofo. I have a apex exhaust and I have to use the silencer to keep boost creep in check

well im getting the fuel controller safc but i was hoping to tune it to run with the stock injectors if possible, cant afford the injectors right now, but on the boost leak issue i ran a boost leak test and my bov was leaking got a new one and i dont hear any leaks other than just a little one from the oil cap but i dont get any movement from my boost gauge.

i found a leak by my throttle body elbow (upper ic pipe) it sounds better but i will try another boost leak test now and see but i should see movement at my gauge right, and is it normal to have a leak at the oil cap? thanks again

You should be running more than 10psi stock. Do you have a boost gauge. Most people say not to go over 16lbs on stock fuel system. I wasn't cutting till 22lbs on my 2g with a 16g so maybe it's different between gens idk.

That sounds pretty crazy for a stock system to run 22 with a 16g mines cutting at around 15 or 16psi

yeah i am gunna go with dsm link over safc and then get injectors 255 and what not so its gunna be for me
1. mbc
2. apex n1 dp and wchaust
3. dsm link
4. mods like injectors and what not

I’m havin the same problem with my 1997 Eclipse gst everything stock other than evo 3 big 16g, 510cc injectors with Greddy profect b boost controller with walbro 255 and hitting fuel cut right away I also have no tuning software in this car. I run Efm link v3 on my other one but this one nothing yet

 

[Sasha Gironda]

Ecm link v3 sorry
