Ok. Wasn't sure what magic happened in the last couple of days to get it idling right. Apparently the MAF issue wasn't part of it.

Sucks bro

I own a legal machine gun and I want to dump a 50 round mag into the car so bad right now and I love the car!

Car modding is frustrating at times. It has to be that way to make the times when it's running perfect that much better. I assume it's similar to what avid golfers go through when they have terrible rounds but hit that one perfect shot on 18.

I was sitting in my office today mad as hell at the car when the tuner and shop owner called, they don't want me to give up on the car but I'm just out of energy to try again. They want to try MAF tuning it again but we still have the uneven air flow so we would have to redo the pipes for a third time so I said no. I went up to the shop to take some pictures for the guy that made the plates for me and there was a guy at the shop who is infinity certified and a fabricator that was looking at the car. When I told him about the pipe problem he asked if we tried running the car with nothing attached to the intake of the y, we had not tried that. I disconnected it so there was just straight air and the voltage is still way off so we have been wrong all along! Any ideas on how that can be? Im thinking maybe one TB isn't closing all the way so it's sucking more air? I don't know how we can test that but I'm about to start trying to find out how I can check it. The shop owner is going to voltage on the TB sensors when he gets back to the shop.

I'm waiting on the cooler for the intake from stillen, like an idiot I didn't keep it so I agreed to keep trying until I get the part then the car goes back to the way Stillen had it.

That's why I wanted you to try it with the stillen pipe to see what the mafs would do, but they had cut it. I figured it wasn't the pipe design after you tried it with the exact way I have it since my mafs are reading near identical. This is also why I was pointing and asking about the maf extension cables. Didn't they have to recut the wires? Are they sure they are 100% wired up right? I just don't understand how going back to the way stillen had it will fix anything at this point. If your mafs are not reading correctly now, by installing the old pipe and a water setup will not fix their readings. If you had them set up as a pull through today and they did not read correctly then it wont change anything by placing a sc in between them and the throttle bodies. Id look at those maf connections again.

I think this is all a blessing in disguise and you will be victorious very soon.

Im guessing they have went through all connections entirely on the car. If you have a vvel clip not fully seated it will run very rough. I found that out myself.

Where is the VVEL clip? We have checked the wires. They cut the old extensions out and soldered it back and all the colors match. The new extension have a male and female plug.

Run the throttle body relearn procedure and see if that helps. I have to reset my throttle and idle after my tuner flashes the Ecutek several times cuz it gets out of whack.

You know you spend too much time talking about cars when your iPhone autocorrects ECU to Ecutek:rofl2:

I thought it was the pipes causing the messed up voltage so that would go away if we changed it back. I now realize we would still have this problem.

Ever since my 3rd or 4th flash with Ecutek my car has had really rough cold starts. Could this reset help that at all you think?

That I don't know but it definitely isn't going to hurt anything. I also don't know if this is a Nissan ECU issue or an UpRev issue. I haven't made the switch to Ecutek yet.

Mine is doing the same thing right now.

Yeah my old tuner gave up on me and said there was nothing else he could do to fix it. Sebastian is going to be giving it a shot pretty soon in addition to a few other problems I am having. Once it warms up it starts with no problems at all but cold starts are horrible.

I would try the reset, it can't hurt.
