Sounds like the old 510ci big block chevy motored '78 TransAm that I used to run around in. :D

Wow, sounds beast! Would love to hear a rolling vid! WOT throttle? Lol

Dear god I'm all smiles.

X2... I want this .. Is only idle affected? Or does the rest of the map get affected? If tuning can be done to affect idle and be beneficial for the entire map while making power then I surely would want a tune like this... But if it only affects idle and can setting not being able to run at WOT or run less power then I would not want it.

Great job though in innovating and experimenting.:tiphat:

Awesome!

I don't know about you guys but I don't want my car idle like that..

^ same here.

Thank god someone else feels the same as me. That is not normal actually sounds terrible. With the amount of money I have put in the heads if something broke trust me its not cheap and it sounding like that you will have a good chance at breaking something.

Lol for me it was meant as a joke... but I do wonder if the VVEL settings can be applied on a per map basis so I can keep the stock settings on a less aggressive setting for rainy days.

Idle sounds nasty!!! :facepalm:

It sounds like any big block old school American muscle car.. Just throws people off because its an import car but it didnt throw and codes so I don't think it caused any problems.
Personally sounds beast to me, imagine pulling up at a red light and everyone hearing this. Everyone would be breaking neck tryna figure out how the....????

When my M370 was installed improperly, it sounded similar. I admit, it sounded kinda cool, but it did not run well at all.... When diagnosing the issue, I threw it on the dyno, made 225whp when not even 2 weeks ago it put down nearly 90whp more.

How was it improperly installed? I did the install myself and it was pretty easy and self explanatory. What did they do wrong? Oh and btw if I heard that sound at a stop lighting would laugh cause it would sound like a misfire or the car was barely running.

Shop didn't see the metal plate that needs to be there, so there wasn't a good seal. I bought it used so no instructions. I downloaded the instructions Tony emailed to me and started started checking EVERYTHING. Then I couldn't find the metal plate. So Tony @ Motordyne sent me another. I found the original while it was in the mail. Luckily I did because the new one did not align properly... That was a good hour of troubleshooting. And a pissed off Wife, as I called her at 0130 to come back to the shop and drop off my parts box. I didn't get any sheet action for the next two weeks. But yeah, easy fix, extraordinary headache.

Lol yea man on an import it would be like wtf.... But on an ol school big block it would be like Wwwoooooowwwww! It's just the fact it's in a 370 that prolly throws people off.

:iagree:

Would sound even better outside of a shop but like stated the sound might not fit the car. To each their own but i have known nobody who would think that sounded bad but then again we are on an import forum.

Both my friends 70 fastback and 67 camaro sound cammy like that at idle but not quit as strong.

O&G's upload sounds nothing like what is posted above in my opinion.

Was referring to revving, they sounded remarkably familiar. My idle was pulsing, but rythmic and more worble.

The clip i uploaded was my Z with NO exhaust.....strait headers. I have no idea how it would sound with eaxhaust, cats, etc.... JTran has figured out the cam timing but its the lift that he cant figure out at the moment. He hasnt messed with it for about 2 weeks, many other cars and projects going on at the shop. Im still waiting on parts and fab work so my car is down at the moment. I dont think ill have comparable numbers untill after xmas. I know he was able to make 29 more wtq @ 2900 rpm. He told me VVEL timing adjustments will help at low mid range but the top of the rev range will benifit more from the lift adjustments when we get to that point. There is still alot more to figure out safely, im not trying to rebuild vq37 heads.

During my brief exposure to the beta version, it was not map-changable.

Like a few other items (Fan Control, for example) it is one for all and all for one.

That may well have changed by now (but I doubt it).

Bump for some updates and love :)

my wife used to say that about me ... about 20 years ago. :tup:

Sounded awful. it just sound wrong guys, was considering Up Rev but might go on the other direction if such tuning is Okay. In my region we have authorized dealers or tuner shall i say. but I don't trust them with my car, can Up Rev do a custom tune by shipping them my ECU? If so who is the best tuner out there?!

I am by no means an expert on tuning but it can be done remotely. Khoi Ha, Sales and Marketing, AAM Competition provided me with the following information; " As far as tuning goes, most places will charge about 600-700 for a dyno tuning session with the Uprev flash license, right now we are charging 599 for this service.

The difference between dyno tune and e-tuning (or remote tuning) Dyno tuning takes at most a few hours, you have the convenience of doing all of your pulls on the dyno and can adjust your maps at the tip of your fingers. It's convenient, quick, and effective. However not everyone has access to a reputable tuner, or a tuner at all within reasonable distance so they Uprev offers the standard cable, which you can buy to hook up your laptop to your car yourself.

Remote tuning is simple, can be just as effective as a dyno tune, but requires you to do your end of the work too. Instead of doing pulls on the dyno and adjusting the map in real time, now we (the tuner) send you a map, you load it to your car. After the map is loaded, you hop onto the highway and log certain/specific data points, via the cable and your own laptop (and the software), these data points get saved and sent to us, we analyze the logs and adjust your map accordingly, and send you an updated map. You go back and forth a few times until your map is perfect. A bit more complicated but by no means is this method inferior to a dyno tune.

If you do get a dyno tune, I highly recommend you ask them to take it on the street and fine tune/street tune it as well. Although dyno tune can be very accurate, depending on the dyno, it doesn't apply real world load. Some tuners will argue that street tuning a street car is the way to go, and dyno tunes are for those just looking to make crazy numbers, haha I say the best of both worlds is dyno tune, then fine tune things on the street!"

You should PM Khoi, he is very knowledgeable and provides outstanding customer service. I hope this helps.

It did help a lot!. E-tunning seems to complicated to be honest however, it would be the only alternative in my case. I'll try to hook my self up with our drag racing team in Qatar "Al-Anabi". Hopefully they can do UpRev tuning at there convenient. :yum: Thanks for the tip

Anyone knows what is the difference between locked and unlocked UpRev tune?. Obviously one is adjustable and the other one is fixed but which one would you go if you want a Full bolt on setup. does it worth it to have the car tune after full bolt on mods? is it a must to save my engine from quick failure

A locked tune just means the rom can't be edited by anyone but the person who locked it. It's a way for a tuner to be sure his work isn't used by another tuner without their permission. I kind of hate it, but it makes sense from the business standpoint.

I personally would never load a locked tune unless the tuning was being done for free by someone local who doesn't mind being bugged for tweaks.

Remote tuning is based upon the tuner's experience with tuning that particular car or, more specifically, engine and "what makes power".

Data logs can't log power output. Most e-tuning is just to keep AFR in the range that's wanted as well as any other indicators the tuner knows to look for based upon past experiences with that engine.

The only way to effectively tune specifically for power is to do it on a dyno, in real time, so that the tuner can see what does and doesn't work with a particular setup with a particular set of environmental parameters.

I've started arguments on this forum with statements like that, but it's true. You can't do science without proper data and you can't get the relevant data needed to be 100% accurate without collecting that data yourself with proper instrumentation. Everything else is best effort with known parameters.

(Which to be honest, is more than enough for most of us haha)

Well-explained sadly the 370Z is rare so yea... wish me good luck with finding a local tuner to dyno tune the hell out of the Z!. Heard few people talking about detonation if the car have for instance (Full bolt on) w/o tune.. Any opinion on that? Thanks :ughdance:

Coldfire you should come down to Abu Dhabi for a day and get her tuned here ;)

See there, you got yourself a regular community going on 'round there!

I've been to GTZ forum.. Extreme Performance in Dubai "Khalid" seems to be the hottest demanded tuner in UAE. I will be in touch Sam my FI full bolt on setup will be here in Qatar around April.. I need your advice will PM you for sure :D Cheers

You're spot on man!

Cheers,

Forgive me for not reading through all 21 pages, are there NA gains and are tuners using this at all? Planning on getting mine tuned in a few months after winter brakes(brakes ahaha, wow, I just did that), or maybe I should wait if this is still in development/worth it for NA.

thanks guys!

Any update on VVEL tuning?

Any update on VVEL tuning?

Any update on VVEL tuning?

I just recently got an etune from Uprev and Randy says they do not offer it yet and he said that the VVEL is tuned good from the factory that after some runs they were unable to get any gains with a bolt on Z.


So far only one I've seen is John@Z1 offer this and has seen some gains from it.

Thanks for the info!

I saw in UpRev's Facebook that pro tuners have the Beta version for VVEL tuning.

Hope someone in this forum that has had any experience with this would comment about it.

The VVEL is really going to shine with the guys who have FI,you N/A guys aren't going to gain that much at all.

How do you figure?

How does changing the profile of the intake cam more dramatically affect the FI systems for the 370 than N/A?

The TT guys maybe could tweak it to add duration and lift earlier and spool faster? Maybe?

I dunno, you can't make it open any further or anything than it already does, that's why Uprev is saying they weren't able to get much out of it. They smoothed the curves a little on my car, but that's about it. It already goes to maximum (safe) lift and duration on the stock tune.
