I have berk HFC, and CBE and dual pop chargers (intakes) on order and will be getting a tune with my install.

Question: I'm also planning to put in lightweight clutch flywheel in. Will that affect my tune? Should I wait to install my breather mods till I have the clutch and tune all at once. (I don't want to tune twice due to added expense)

It won't grenade your engine but it's not really great for it. If recommend new plugs when you do get the tune. Also with that motordyne plenum you'll actually lose power without a tune

I would say be on the safe side and get the tune, or don't put all the stuff on until you can afford the tune, then install and tune. Just to be safe.

I'm currently running FI CBE and LTH's. I plan on getting the stillen Gen 3's soon. Just wondering how critical the custom tune is. I really wanna put the Gen 3's on myself and then drive the car to the tuner about 30 mins away. Just wondering if staying off the go pedal some is good enough for the drive to the tuner or if I'm better off just having the tuner put them on and be done with it.

That's definitely okay and will save money for another mod.

Install them yourself for sure, driving around won't hurt anything at all. I would get the tune reasonably soon, but it won't hurt you short term

Ok so i have the ARK Grip V2 exhaust and i just ordered my motordyne ART pipes. should i wait to get my intakes to get a tune or should i tune it after the oil cooler/CAI's? =]

wait until after CAIs imho.

I just finished full breathing bolt on's and Dyno tune. There have been some comparisons with and without tunes on this thread:
http://www.the370z.com/tuning/56385-...ng-mods-3.html

I believe about 1/3 the measurable dyno gain came from the tune. Much more importantly though, better throttle response at lower RPM seemed to be the best gain from tuning. I posted a full review if you are interested.

I just put an FI exhaust on my 2012 and I'm thinking of doing an UpRev eTune since there's no UpRev dealers within 200 miles of here. Do you guys think I should do this or find a local dyno tuner and settle for something other than UpRev?

there is no option other than uprev

what better way to appreciate a new tune than a 200 mile pre/post test drive :driving:

Haha good point. I wish the closest one wasn't in Houston. :eekdance:

I have not done this, but I think Uprev will send you a kit and you can get a pretty good tune with them using logging etc.

do a search on this forum. I know I have read of people getting pretty good results that way. I am NOT speaking from experience (am lucky to live close to a tuner)

Basically the way the etunes work is they give you a base map that gets the tune kind of in the ballpark, then you have to datalog certain engine parameters while you drive around (rpm, load, AFR, throttle position, etc etc) and email it in, they compare that to the tune file and make some adjustments. You get the updated rom file in your inbox, flash it onto the ecu, and repeat.

Honestly etune or dyno tune it all comes down to the tuner. Yes a dyno tune will give you more exact IMMEDIATE results, and the maximum power potential if performed correctly, but I've seen a lot of tunes that were FUBAR'd.. just because the guy owns a shop and has a dyno doesn't mean he knows what he's doing. With an etune you can get pretty darn close with these new cars but it is not immediate. It takes time, patience, and can't be done in 1 or 2 updates.

:iagree:

I have read some great results and satisfaction from etunes. 1 hp and <1 whp less than a full dyno tune will probably not be noticed in the final analysis, and you will have some DIY pride of ownership in you tune too!!! Also, you will not be running "lean" after your bolt ons (I read but do not understand WHY this might be harmful to your engine). With an E-tune you can flash the moment you finish tightening your last bolt and be pretty close with a ballpark tune right away.

From what I read of your situation, I think this is how I would go in your shoes. (It won't cost as much either!):tup:

p.s. wOrM,

That is a good looking Z you have there. Love the paint!

I'm sure this answer is somewhere in this thread but... I put on Berk hfcs and ark exhaust, do you think its worth tuning or would it be a waste of money. Does it kill the warranty if tuned? :tiphat:

a tune is worth the money even without bolt ons! Definitely get a tune with the HFC's because you EDC can adjust somewhat, but will have a tough time compensating for so much more airflow.

Also, 30% (or so) of your increase in performance will come from tuning your new breathing mods. On this car the HFC makes the biggest difference IMHO. The tune will help throttle response and give you some cool new map functions as well. (like valet, and kill switch modes). It it definitely worth the price of getting it done. (about 5-600 bucks if you get it done on a dyno which gives best results)

I reccomend you ask around on this forum for a good shop in your area.

I cannot speak definitively about your warranty. but I know there is much discussion about it on the forum. Do a search and I'm sure you'll find your answer.

Good stuff! +1 rep for you!

Thank you sir! :)

I already have CBE and HFC installed and looking to add K&N drop in. Do I need tune for that? I read that you need a tune if you have 3 breathing mods...but does filter counts as mod? I may add the maf tube later on.

You're probably OK with that setup, since the headers are stock, and its still catted. If you want to get Max performance and be safe than it wouldn't hurt To get a tune.

So I just installed my FI CBE and HiFlow Cats, and the stillen Gen 3's. I wasn't planning on getting a tune just yet, but I feel like im burning through gas faster, any thoughts?

Tune it

Well that was easy

Haha. As long as all the breathing mods are done then you're ready. If you'd like to upgrade flywheels, pulleys , or anything like that for more power it won't require another tune because they don't have anything to do with air. If you plan to do headers or an intake plenum then you'll want to wait. Other than that just find a reputable shop and get it done.

Yea I wasn't planning on doing it just yet, cuz im on the fence of getting the motordyne manifold, but I feel like im spending a lot more time at the pump and I hate that:shakes head:

I've read mixed reviews about the Motordyne manifold. Some people report that they didn't get any gains from it, and some people actually lost torque in the midrange by a fair amount, just to gain 2-3 hp at the very top end. Make sure you do your research before you pull the trigger. If you're gonna get it, then I would wait like Footloose said. Otherwise, you don't NEED a tune, but you can definitely benefit from it. :tup:

FI exhaust, stillen gen 3, berk test pipes. Tune needed?

Read above posts^^^^

Your question is like most peoples and was answered multiple times before.

My bad

I have

ebay y-pipe and a muffler with manual closing/opening valve system.

Id like to throw my exoticspeed hfc on my 2010 Z, but 2/3 german tuner say the Z will drive too lean and the ECU will not comensate enough the new mod!

Whats right now?!

Get an uprev tune! Your car won't run lean to the point that it will damage anything, but a tune will make it run so much better

+1 for a great seller. Love my uprev, thx for your help.

Thanks, but I dont want to flash the ECU because I dont want to void my warranty.

Will I run too lean?

K&N filters
exotic speed 300 cell hfc
Muffler with manual valve system


Thanks!

If you don't want to get a tune but still run HFC's, I would suggest AEM's CAI with ETI. It helps the intakes compensate for their diameter difference. The ECU will makes it's own adjustments on top of that. My AFR's were averaging 13-13.2:1 with LTH's, full CBE and HFC.

I dont want to upgrade the intakes too : ).

Will I run lean?

How did you measure your AFR?

If you just stick to Post maf tubes and drop in's, I think you might be okay. 300 cell cats will keep things closer to stock as well. You can get AFR measured when you dyno it, or via software.

Could I measure with Torque app the AFR, that I might be too lean?

Look at the video:

Galaxy S2 Torque App mit Track Recorder (Teestfahrt 1) - YouTube

Lets say I installed a CAI and HFC's, about how much does a tune run you?
