Camaro Zl1 LT4 tune

[hy_bmw_freak]

Hello guys im from Germany first sorry for my bad English me and my tuner tune my LT4 but i see small issues on the log my tuner say seems like a normal.

But I would be say not, also you can see on the @wot the tb is closing early before i hit the rev limiter or change the gear and it seems like it not full opening on specific rpm

Also i send you my log from the stock tune and with tune from my tuner but i can say we are not finished yet car runs very good and strong now
And on the stock tune i don't see any boost increase before hit the re limiter

thanks for your help

Mod list if its important

Kong x ported blower 2,30 pulley
Kooks 1 7/8 headers with 200 cpsi HJS cats
103mm tb Nick Williams
rotofab intake
mighty mouse catch can
ngk tr6ix spark plugs
msd wiring
rear crimp exhaust removed
Tune is on 97 octane pump gas =Germany 102 octane
( heat exchanger on the way but not installed yet)

If you don’t get any help, let me know, I do a lot of remotes on these!!

Thanks for your reply what do you think about the graph I think it's not normal correct me if I'm wrong ?

[HeroldMotorsports]

also looks like Multiple different PIDs for the same thing. Make sure to log with only the correct one so your data isn't getting skewed. If you'd like to send the file I can make a small adjustment to see if the throttle stays open for you. Or I can send a channel config for you to test and see what it does.

[hy_bmw_freak]

hell yeah my friend i send you a file you can do it both i send you my file

Its like tb it's not opening always to 100 % but you can watch in the tune im not a expert, but my tuner want change anything on the torque management and tb setup

also we are not finsihed with the tune but i think 80 % its done little chances on the timing table and tb function

Try this file and this channel configuration and see if the throttle still closes on you. There is a few things id look at in the file but it's overall not bad at all, just needs cleaning up. The VVE is untouched (not sure if he is going to address it or not as I see he has pushed the Dynamic to disable but Gen5 is still going to reference the VVE regardless) Also looked like the High side of the VVT tables were changed, not sure if he did this for a reason or not but it is changed.

If theres anything else I can do for you guys just let me know.

Thanks buddy I will try it 👍 🙂 but the weather Is here shit everyday rain if it it's dry I want do it

can you tell me which tps layout or signal is the right one if i see in the log

first one TPS signal ( sae)

or sixth one TPS relative (sae)

because if i chance the TPS signal from SAE to relative SAE is the TB always open @wot also on my old tune file and log.

The channel configuration I sent above will have all the correct channels for you.
You can edit/add/remove anything else you may need off of that.

Pretty standard setup. Ben can take care of you. I would help but I'm in the same camp as Ben. Since I tune dozen and dozens of this exact setup, I have a certain way I do things. I don't try to fix others tunes because it opens up a whole can of worms.

Hire Ben to remote tune for you and enjoy.

[hy_bmw_freak]

hello i make small log but i cant go a lot wot because the streets are here wet and full maybe if its dry i will try again.

tripinatz : Thanks for your support but i pay my tuner now i think he is not so good like you because he tune not so lot many us cars but he is good tuner i think.
we are not finished yet for my was important that the tb is 100 % open if i go to pedal to the metal and the boost before and after shifting dosent drop down.

if the vve table is working now i will make a gift for the herold motorsport and make adversting for him here in germany he is a nice guy he help me now.

but i will see what is going if i bang the gears from 3 to 4 gear if the tb is full opening and if the boost drops down.

Like TriPinTaz said, hire Ben to remote tune your car. DO NOT let "spencer herold" or "herold motorsports" or whatever he is going by these days remote tune it. I've had experience with this guy's shop and his "tunes" and it has cost me a lot more in the long run by having to have someone else redo everything I paid him to do. His "tuning" was almost the demise of my brand new ZL1. DM me and I can show you plenty of what I'm talking about when it comes to his quality of work.

[hy_bmw_freak]

@oilfiled_trash21 thanks buddy what you mean who is ben? what was wrong with your tune ? do you habe smilar same setup like me ?

what is wrong with herold motorsports? he want me to help i hope my engine dosent blow up now ^^ no im joking

@herold my tuner ask me how is it possible does it intervene in the background with the vve table.
and what make the vve table can anybody explain it to me you can change the values ​​simply like that without authorizing the car ?

[TriPinTaZ]

If your tuner is having an issue tuning that setup, he doesn't know what he is doing. It's a relatively easy build to tune for. VVE is Virtual Volumetric Efficiency and it plays a role in torque calculations in the Gen V stuff and can cause throttle closure if the torque model is off. Sorry that you had a bad experience but you wont get anywhere without posting the tune file if someone feels like taking a look. Podting logs aren't going to help with anything.

You spent a bunch of money for a car and build to make it fast. Spend the $300-$500 on a tuner that KNOWS that platform and can get you fixed up quicky. I don't understand why people try to patchwork bad tunes and won't acknowledge the mistake and just make it right and enjoy life.

Best of luck to you. I hope you get it fixed!

Ben Charles, he's on the forums here. He actually posted a couple of comments in on this thread about helping you tune it remotely. Where do you want me start on the work and tuning they did on my Camaro?? Right away the plug wires melted from the headers almost glowing due to it idling with -10 to -14 degrees of timing. Drivability was absolute s**t. I had to fix so much mechanically before I could even begin to attempt to fix the tuning. Do a search on Camaro6 or Google and look at the reviews. There was a guy from Houston that posted a nice little video about his experience with his Hellcat at that shop. Best thing to do is stay away from that guy, his tunes are a joke. My mods are similar to yours, except I have a cam and a 9.45" lower and 2.4" upper pulley. I had to basically load the stock tune back in to the car and start from scratch after fixing everything mechanical and removing the "herold motorsports special remote mounted TMAP sensor". I've just now been able to get it to maintain a decent idle with positive timing. These Gen V's have a steep learning curve. There's a wealth of knowledge here if you put in the time to read and study what others have done.

Thanks buddy for your Answer I just want to now what All need to be changed to run lt4 without any problems the car runs good and feels very strong I just ask and let you watch what's going on for me is the money not the problem but I want just a good tuner that's because I'm here 😀.

That's because why I send my file here to check out from good guys to see if the tuning is right or not.
Money is not a problem
I think if anybody can help me with out with the tune

sry but I'm not from the USA I'm here only in Germany and here to find good tuner is very rare and how can I trust ppl in the USA if I has no experiences with good tuners that's why I'm ask

Don't be upset to me I'm only here to asking whats going on on my tune

Ohh man I'm so sorry 😞 thanks for your Answer and helping I just want to now here if my tuner is on the right way or not if not.

I'm ask just for the why the changes do not have to be made how or where no one should reveal their own experiences or secrets here I would like to understand why this throttle body is closed and why you have to make a change to the driver demond or vve what kind of influence that has.

I don't understand the Logic behind this system

Try the tune Herold posted. I actually looked at your tune and the biggest thing that stuck out was one of the things Herold changed in the file. None of his changes will put your motor at risk and it might just fix your issue. Your original tune isn't bad after all, just a couple of weird things done that don't make sense.

Also my friend that is what i want to hear thanks for your support. I'm talk already with Ben Charles at PM but i don't see his first post in this thread i think i was blind.

What you mean with weird things can you explain that ??

Also if i watch in to my logs with stock tune and with tune i see only difference the between the boost droops down before and after shifting on high rpm you can see that in the log ccm6 and if you watch to the stock tune boost don't drop down.
For me is that important to know if its tune results or any hardware problems and you have been a great support to me that is what i like.

Thats for your help guys

I'd choose Anybody on here except Herold Motorsports, smart move with Ben Charles. I'm personally using Greg Huggins to retune and fix everything HM did wrong. Idling negative spark which was causing high temps in the engine bay and melted 3 different sets of spark plug wires. Maf only tune on a cam/ ported heads change when it was specified as maf and ve blended. Knock sensor sensitivities changed to dangerous levels, both detection and refresh rate. Looking back at my logs, even after just basic boltons his tune had negative timing at idle and tip in. Just a fair warning, good luck with getting everything resolved.

Well the weirdest thing would be why did your tuner reduce the Driver Demand table from OEM values if you added power mods to the car. Also, I don't agree with lowering the dynamic airmass to favor the MAF heavily with those mods. I think its important that you maintain other parts of the tune to ensure transient fueling is in line below 4000 RPM. Drive-ability is better too this way. But we all have our own ways. The Driver Demand table was very odd though.
