I dont think that removing the clamps are going to solve anything.

i agree
Think what you want, but you were able to get fuel cut still when you had the standback on there, right? Didn't you still have to lower boost to stay out of it? How about since you removed it? Have you been playing around with boost at all with no clamp on there?
the standback doesnt do s*** besides clamps the map. i got rid of it because i didnt like it, didnt think it was worth it, and simply dont liek cpe lol. my car hit fuel cut or boost cut, only in weather under 30 degrees, at 18.1psi. its not a map problem, its a temperature problem. i just got rid of it like 3 days ago. im probably not playing with boost untill something worth while comes out....read cobb ap due late feb early march...untill then its cobb sri, ets 3.5, full tbe.
unclamping everything would just make it worse. once the map sees over 18psi its going to cut no matter what.

Take a strole down here to Missouri, and I'll show you exactly what happens at 18, 19, and even 20 psi with nothing clamping the map at all. Better yet, wait til there's ice and snow on the ground again.
BTW, if it's not a map problem, then why would unclamping it make it worse?
You were likely hitting fuel cut because your fuel pressure and maf were not on par with your map. The temp effects the maf reading. The colder it is, the more air the ecu knows is going by. Ecu saw alot of air coming in, but couldn't figure out why the map was still reading low. The safest thing for the ecu to do when it doesn't know what's going on is to hit fuel cut. It doesn't take a rocket scientist to figure that out.

Dude my car fuel cut like crazy without the clamps....Every time we lowered the voltage it got better and better.
Ugh your fuel pressure is variable on these things dude. Were going from a rough 17XX PSI with a stock pump into the 2200 psi territory with a modded CDFP.. Since you are so intuned with these cars and know so much, how about solving all of these issues for us? The problem is the ECU, plain in simple. UNTIL a complete overide of the STOCK Flash is overridden, there is NO piggyback solution that is going to fix our situation. Its either stand alone time or wait for COBB/SCT to give us what we need.
You do realize that the computer under lower temperatures, is going to ADD timing. There is NO increase in airflow through the engine at colder temps The computer is adding timing and somewhere along the programming lines of a certain temperature mark, the computer is making adjustments to an area the standback cannot compensate for. His fuel pressure is fine with his bigger pump, so i dont know why your taking people onto another path that doesnt exist.
Add nitrous to your car and see what happens... that will prove whether your theory is correct or not.

Yes, but did you have the upgraded pump installed?
Duh! Fuel cut used to be pinned to the fuel pressure dropping off. The new ones don't (yet). Since the charecteristics of the fuel cut have drasticaly changed with the new pumps, it obvious does plays a big role.
The rate of flow doesn't increase with the colder temps, but the mass of air that gets in at that same rate DEFFINATELY DOES increase. It's called "density" and it goes up when temperature goes down. If you don't think the ecu knows that, then I don't know what to tell ya. I never said his fuel pressure wasn't fine with the bigger pump, so...? And what non-existant path are you talking about? The point I'm making is that since he has more fuel on call as well as more air, and everything can physically work together w/o a problem, let the ecu see the higher map. I believe as the map increases (even beyond what we used to think was a limit), the ecu will simply demand more fuel until it sees the rail pressure fall. I think the map was only a limit due to the fuel system. That's why clamping it fixed it. The ecu never had to call for more fuel than it could get with the map clamped. Now since there's more fuel on call, it only makes sense to raise the bar, if you will.
Now that is truely ricer logic. There's no way in hell any ecu could self-adjust for nitrous unless it had sensors specifically to pick up on it and it was configured to do so. Now a 20 shot I could see "maybe" not having much problems, but I still wouldn't do it with this intake manifold though.
you really dont know what your talking about. how come i can hold 18 psi up top and not cut out but i cant hold it down low wihtout cutting out. Theres a difference btwn holding 18psi and spiking 18 psi. Shut me up and post a video of you doing a 35roll in 4th gear. Show both your boost guage and rpm. i want to see you hold 20 wihout clamping anything. make sure to get a shot of the car ambiant temp reading 30 or lower.
Ugh, i guess you just cant read. Nevermind. You're a lost cause.
