You can adjust it but the adjustment uses the MAFs to control the trans. I'm done, this crap is coming off the car today!

Stillen Air to Air setup
 

I know nothing about tuning or Ecutek but...Aren't the MAFs still functioning just not being used for fuel tables? Couldn't you just pull the voltage reading from the MAFs and adjust line pressure that way?



What if you went back to UpRev?

I don't understand it either but Level 10 told me no one has been able to make it work.

So what if you went back to UpRev. Might not get all the extra bonuses but at least the air-2-air conversion wouldn't have been wasted.

It still works on MAF so we would have to try to make the pipes for a third time.

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.

I noticed in your Sig you were going with ID1000's and E85, same as I have. If you have already made the switch and the weather is getting cold then this is your issue. Cold weather on E85 will cause rough starts.

Not calling BS as I have no clue. What's the theory to that?

Google E85 starting in winter. Theres lots of info on it.

This is also why they change the "winter" blend from E85/E90 to E70. To help with cold weather starting.

I still currently have 600cc injectors and 93 octane tune. My old tuner has been MIA for over a month now or I would have already make the switch to my 1000cc's and e. I do have the GTR plugs and a few people have told me that could be the issue. Sebastian is pretty sure he can get me lined out. This problem has been happening for over 2 months now even back when the temperature was in the 70's. Every once and awhile the cold start even throws a misfire CEL.

Right on.

Here you guys go if wondering.

Ethanol Producer Magazine

Yeah there is no doubt it is much harder starting on E in cold weather. Have about 5-10 people around here that have that problem.

Well that didn't change anything.

When you took the water cooler out of the intake manifold, you just cut a square in the front, pulled it out, and patched the hole? Are you positive there isn't an obstruction inside there that's blocking one of the throttle bodies from flowing?

I would reconnect the front of the intake pipes to the supercharger, and then disconnect the intakes from the throttle bodies. With the supercharger blowing, you should see some voltage on the mafs. If they're still unbalanced, your problem is in the intake pipes or MAFs. If they are balanced, then it's an obstruction in the throttle bodies or intake manifold. At least it would give you a direction for where to look.

We had it off several times, it is completely hollow with no obstructions. We will try your idea to test the pipes, I hadn't thought about that.

I just keep thinking this is not a mechanical issue. It sounds electrical. Some sort of wire is not either connected correctly, loosly connected, or not connected at all.

I almost want to fly down there and take a look. I mean, its 15* here right now! That Florida weather would be worth the trip.

15, that sucks man. If we don't get this figured out soon I might have to buy you a ticket! I'm going there in a few hours so I will go over the wires again.

I too am running the GTR plugs, cold start issue is all in the tune! Last time my Z was tuned the tuner asked to keep the car over night so he could have a go with the COLD start up adjustments to prevent the misfire CEL. I have never once had an issue again.

My car always fires right up however my dads GT-R has a little more trouble. (Both cars were tuned by Seb at specialty Z)

Checked all the wires again including the VVEL and everything is connected. It's dumping rain and the doors are closed so I couldn't try the resets myself, maybe Monday I can get up there

Exactly what I figured because it started up normal with no problems until about the 4th flash. He changed something but told me there was nothing else he could do. Literally was on the 13th flash trying to fix it and haven't heard from him in over a month now. Such garbage. On to Sebastian!

That's a hell of a lot better!

There you go! What did you change?!

All the resets we could find.

My friend I go to the track with has alldata, he sent me all the detailed steps and it worked. Tuner says it is finally able to be tuned. We need to send the torque tables to level 10 so they can set them the way they want and it's ready to get it on the dyno!


Sent from my iPhone using Tapatalk

Good deal man! Yeah I am having to send my table back to Level 10 also. Are you going away from SD to get the trans tuned right or you trying with SD?
