Ok, fair enough. I'm saying that if you want to get the absolute most out of your car; go with the ecutek down the road. Read the reviews. I'm not the only one who is saying this.

My S8+ reads and stores them way to efficiently (Got 2 intermittent codes, showing up at random times and worse of all, it is my inspection month). Make sure you have the Nissan/Infiniti plug in for the extra sensors. That is the only thing I can think of.

Not sure what state you are in, but if you get smog tested, you want to keep it as close to 14.7 : 1 as humanly possible.

As for what is "too lean"... 15:1 is quite lean at full load, but you exhaust gasses may be too hot, therefore failing smog tests. And it gives you knock. Plus it screws up the environment and such. On an N/A engine, I rather have my A/F set between 12:1 to 13:1. Also, if you are running lean, you use more gas, as lean means there is not enough gas for the combustion, so more needs to be injected.

Did I mention knock?

What about this place? It’s in Wisconsin. Their Facebook page shows that they tune Infiniti as well as others with some examples and vids. The only personal reference I can give is a guy I used to roll with had his motor built and tuned there. His car is an STI but man what a beast. He had nothing but good to say. Best of luck with your probs and please keep us updated as we need more feedback on the local tuners for Nissan up here. http://quantum-performance.com/

Fwiw i have a 13 IPL and have gotten maf codes with stillen gen 3 and aam competition S-Line cold air intakes but never with the takeda cold air. Each time I reset and would randomly occur throwing me into limp mode. Super random doubt it helps but I've definitely been in limp mode because of the intakes.
No tune here.

You originally posted this review in February.....have you been having issues that long??

I'd be furious at this point. Have you contacted anyone in management yet?

I'm also going to agree with others, while my G isn't tuned, I've used canned, mail order/etunes and dyno tuning, and with your mod list, I wouldn't trust a standard tune without at least providing some logs to the tuner

Air/fuel ratio should be 14.7:1 to 14.9:1 at light throttle. Full load should drop to 12.5:1 to 13:1. These are not Vq-specific, rather a general guide.

I was on vacation so it looks like I missed a bit. Let me see if I can get caught up. Thanks for all the help guys!

I don't doubt that at all. What I was trying to say is that I think Z1 should assume responsibility for the tune and fix it before I have to resort for paying for another tune.

I do have the Infiniti plug in. The Torque ap was working just fine on my old phone. I can clear CE codes on the new phone, but it does not show what they are. Weird. I don't get smog tested here so no worries. Just wondering the ratios I should look for if I can monitor them.

Thanks for the info. They are only about a 1.5 hour drive from me (much better than Chicago). It looks like they specialize in Subaru and I have raced 3 of those so I am sure we would have lots to talk about if I go that route.

Furious is an understatement! It is like trying to deal with United airlines customer service. I just keep getting tons of delays and excuses with how busy they are all the time, waiting for a cable to come back, big event coming up, not enough people answering phones, blah blah blah. But if you want to order something, they take your call right away.

Really annoying and I cannot in good faith recommend Z1 anymore. It is a shame as I think they have good parts in general and some of the guys that work there are very sharp. I am actually still considering their subframe bushing inserts. But stay the hell away from their mail-in tunes! I really still hope it is just a matter of turning off these codes for MAF sensors, but if it is really that simple, why in the hell has it taken so long?!?

They only do Uprev tunes, but seem to know what they are talking about. It sounds like they specialize in Subaru, but their tuner was a master certified Nissan tech before so that is a bonus!

Well, Jon from Z1 sent me a few different tunes for my car last week, but really only because I hound him about it. I can e-mail him a data log, but he will not get back to me unless I leave multiple messages for him and then wait on hold to talk to him. It is frustrating because he did adjust and send me one tune while I was on the phone with him and it did not even take 3 minutes.

I am glad that we are at least making some progress and the car seems to be driving well, but I wish Jon would at least return a message or offer to do something extra for all the hassle. I understand if you are busy, but at least show a little effort or have someone else from Z1 reach out to me.

So lesson learned the hard way- if any of you get the Z1 400hp package- DO NOT get their mail-in tune. Get it tuned locally on a dyno.

I used to recommend z1 to everyone I know, now Iíll recommend eBay sellers in China before I recommend them. Even dealing with them in person is an absolute nightmare. I would never be able to trust them with my car again. However, Jon is one of the best in the country at tuning uprev. And if you talk to Spencer on the right day he will make **** happen. Other than that, good luck... still havenít made it right with me so I took business elsewhere...

This post is a rant about Z1 and their terrible service (mainly Jon who has yet to return a single call or e-mail in 2 months) and why you should never do their ECU mail-in tunes.

So it has been about 2 months now and I am on tune 13.

Not only does Jon never respond, he is also nearly impossible to get ahold of every time you call. I had to call Z1 7 times today just to talk to Jon once. He told me that I should not have to do any more data logging and the tune I have should be good. I thought, "Thank God I am finally done!"

Then he sent me a new tune!?! WTF!! So I had to spent most of my afternoon calling Z1 trying to get through to Jon only to be told that he did in fact change something in the tune so I would have to waste more time in the snow trying to data log.

Jon also never gives me any detail about what he changes with the tunes.

So tonight after work I downloaded his new tune, flashed it into my car, drove around for a long time trying to find an on ramp without snow on it to do a data log and finally got one good pull.

Now I will spend all day tomorrow trying to call Jon again just to get him to read his e-mail or else I will never hear from him again.

Iíve had similar expirences. They mess stuff up in person just as fast it seems like. Sorry for the trouble, itís time to bite the bullet and get another tuner. That has to be frustrating as hell

Have you asked for a refund yet? The OP was dated Feb-17, have you really been messing around with the "400 HP" kit for that long?

It is definitely frustrating. The only thing keeping me with Z1 is that I do not need to pay anything to have them fix the tune. Now that I know for sure that Jon will never call or e-mail me back I just need to keep calling and calling until I get him on the line so it should go relatively quicker. It sounds like we are close with the tune... fingers crossed.

Yeah they kept skirting the issue of a refund because they argued that they already tuned the ECU and made it sound like it was easy to fix. I think that it could be easy to fix as it literally takes Jon 1-2 minutes to adjust the tune. However, what they did not tell me was that it would be impossible to get in touch with Jon- (every time I call) and that he would never return a call or e-mail.

The tuning issue has taken 2 months since I got the cable because Jon is so tough to get in touch with. The rest of the year was spent waiting for Jon to get a loaner cable back (never happened) or everyone else at Z1 speculating all sorts of other possible issues that I did not think were the issue and were not.
