Neptune RTP questions..
I have a stupid question regarding neptune rtp. Im am completely new to tuning so bear with me lol. I've read all off neptunes info on rtp and the installation of the "demon" directly on top of your ecu. My question is... does this limit you to tuning only one vehicle with it? Since you've installed the demon in a single ecu? I would like to be able to tune more than one vehicle (maybe my brothers) Is there tuning software that would accommodate me wanting to tune 2 or 3 vehicles? If so, what would be the most cost effective route to take. Thanks in advance.
Thanks mtber. That's mainly what I was wondering. Since that's the case and im wanting the ability to tunepossibly 2 or 3 cars, what would be your suggestion. Keep in mind im new to tuning and wont need advanced features. Something easy to learn and inexpensive. Thanks
I wouldn't suggest tuning on crome unless you want to deal with out dated software that has issues.

ok so s300 and neptune rtp are out of the picture for multiple tunes. Crome is outdated and glitchy. What WOULD you recommend?
Is Crome perfect...maybe not. However, it works pretty good for quite a few people that figure out how to use it. The newly released Crome 1.6 works pretty well with the Demon RTPs and the older ostrich units. You can still burn the ROM.bin files to as many chips as you want.
Dealing with Chris and the guys over at Xenocron.com will make things go pretty smoothly. Their DIYer intro tuner package and a Crome Pro license would work for starters. However, if you have guys that want to start buying their own Demon's and software licenses you can tune that way as well.

Its a good starting point.. The GUI is very easy to understand and ANY tuning software takes alittle getting used to, to work correctly. Everytime i tune a s300 car, i have constant issues with them.
A eCtune or Neptune car rolls in and it connects, and live tuning and datalog work fine. Does this mean s300 is not that good of a software? Maybe, maybe not.
CromePro worked fine before 1.6 for me and alot..ALOT of other people. The flaws are few and far between for what i use it for.. i'm not trying to tune 500whp setups with crome..but for people on a budget its a good system.
Trying to learn on a system like the s300/neptune/eCtune , things with a ton more options makes it a tad bit difficult... Gotta see both sides of the spectum.
If the software is so outdated, why do you tune it??

I guarantee you that I have tuned more cars on crome then 99% of the people in the world.
Does that mean I recommend the software to someone who is trying to tune a car them selves?
Definitely not at the stage it is at. It is very close, but good enough for me to recommend it.
Why would you recommend a software that doesn't have any kind of technical support from the developer?
If there is a bug with the software no one is there to fix it or assist you with it.
Concerning your issues with hondata s300 systems:
What issues do you have with hondata cars?
How many vehicles have you dyno tuned on hondata s300?
Where are their dyno sheets?
Please enlighten me with problems/bugs you have found in hondata & the cars you have tuned. I am very curious.
I thought you had issues with neptune?????

I've had my fair share of problems with ALL tuning softwares. Some more then others.
Crome's only main problem i ever experienced was having to choose the correct com port and having to remove checksum all the time. Other then that, Crome operated fine.
Hondata cars have been nothing but a pain when i've gotten ahold of them.. Whether its the datalog not wanting to connect, or the live tuning going in and out, not to mention crashing on a XP computer, and on TOP of all that, i dont support hondata in general for what they "Tried" to do to the DIYer's @ PGMFI.org.
I've dynoed tuned a few s300 cars.
Dyno sheets have nothing to do with software problems that i'm having.
One recent problem was with a customer who trailered his car about 6 hours away to get tuned by me, he was running P/H injectors 750cc i believe, and the realtime wouldn't connect, everytime i made an adjustment, i had to upload it, and then verify it.. No matter the settings i tried it still would need to be uploaded then verify.
The Car ran like absolute CRAP in partial throttle, stock IGN maps... i believe he's switching over to neptune now, sold the s300 from the last txt i recieved from him.
Dont be "bias" because you're a hondata dealer. Every software has bugs, always will, there's nothing that is perfect, but there are things that have solid foundations for learning and doing what needs to be done on a budget.
Dont get so offended because someone's speaking a opinion. There's a ton of people who dont like hondata.

I can assure you that the issues you experienced are completely to do with the vehicle & not the hondata software it's self.
Only time I have ever seen connection issues with s300 vehicles is when the car has an aftermarket ignition system that is improperly wired/mounted.
Has that stopped me from tuning a vehicle on s300? Absolutely not.
I can resolve such issues or I can even tune without live tracing if needed as the system has onboard datalogging.
Concerning Hondata Upload then verify? FYI S300 doesn't have a "verify" rom function. It has an upload function & download function that is it.
Reason I asked for dyno sheets is to show proof that you actually have experience with the system(s) you are mentioning.
Why do I want proof? Because the post made: https://honda-tech.com/forums/showth...neptune+timing
I'm going to go out on a limb and think a little outside of the box.. I had a few cars act kindof weird on neptune, like the dwell ign tables weren't completely compensating like they should...I switched those cars back to crome or whatever else software they had and they seemed to run fine.. they too, also felt like they hit a brick wall, the car revved but just didn't have anymore power..
Through you posting some dyno sheets maybe some videos. I would like to see what kind of vehicles you have tuned, weather it be sub 300 whp vehicles or 500+ whp vehicles etc. Thus far the posts you have made concerning neptune & hondata have lead me to believe that all of the issues you have experienced with any software has been beneficially related to end user issues.

Probably alot that isn't being mentioned by the end user himself. I do know that he had wired in the injectors himself, and redid all the wiring himself, as far as i know it was fine. He didn't pay me to look and double check it, so i went upon his word. For all I know, he could have gotten home, saw there was a problem and redid the wiring and is just playing it off.
I've tuned all kinds, mostly sub 400whp cars. Tuned quite a few domestics too, the one that i'm talking about now, was a b20vtec, on 10psi on a sc61. If i had to guess it should make somewhere in the 290-320whp range.
I've not had any problems that couldn't have been fixed with neptune,ectune or crome, the hondata problems have been on and off, but i've experince those at least 3 times. The majority of the cars i tune are on either of the 3 systems i mentioned because thats what "I" prefer.
Can't dictate tone on the internet, and from the way you word your typing, it sounds like you were getting upset. In the end, my customers are always happy, and thats what matters to me.The whole "problem" with neptune i was having was when i beta testing the RTP board for craig. Neptune had just been released and i was trying to use it on my car, and ran into some issues with the car not wanting to go anywhere but rev in the higher rpms. That has since been fixed by JR, James knows what he's doing, but thats neither here nor there, i was throwing out an idea...of something to look at.
I simply want some facts & actual useful data.... Not hearsay from some one who claims to be a tuner that has only tuned a handful of cars and can't produce dyno sheets to show any kind of experience under their belt.
So, the issue was on one car?
That contradicts your recent post concerning such issues:
FYI, the ignition timing code in neptune has nothing to do with the DEMON or RTP board.
So let's get the facts strait. Were you running into these "issues" on one or multiple vehicles?
Were you on a dyno? You must have been to be able to make such an accurate diagnoses of such an issue.
Where are the dyno sheets if so?

keep looking to argue i'm done.- all softwares have their issues
- crome is a perfect tool to start learning on, way better then any other freeware bs out there like uberdata or turboedit
- just sharing experinces I've had , you're taking it personal, and taking personal stabs @ me.
I own a shop, just like you. I dont just "tune" motors, i build them as well. This isn't some heresay.
Have a good day.

Your "tuning" opinion & experiences should not be taken as a "professional opinion" as you can't back them up with any structured data that doesn't contradict it's self.
By all means please provide me with the answers to my questions.

It's a learning process and Crome is definitely a great program to start with.

I love watching all of the retailers/tuners bashing the competitors products and pushing their wears. Guess we need a bigger sandbox eh!
i wouldnt put AEM in the same class as motec..
i also firmly believe crome is not in the same class as neptune, ectune, or hondata.
who is bashing? crome is a freeware product. Sure its cheap and easy to obtain, but the headaches that are involved in not knowing a damn thing about programming and getting crome to work properly is not worth the hassle.
spend the extra money for a management that is tested and actively supported and the tuning experience and learning will come faster and be more enjoyable.

The only reason I am taking the time of day to question your comments/posts is due to the fact that you are discrediting hard working companies like Hondata & HRtuning with hearsay.

You may be able to research an older user name of his where he photoshopped an old IB graph and claimed it on his own on here. Something along the lines of a 200hp built B20VTEC, I don't remember the particulars Some local guys paid for some pulls on a local DynoDynamics, where he promptly made 140hp. After some tuning (not by him) the car made 150hp. I still have the video of the runs on one of my computers.
https://honda-tech.com/forums/acura-integra-6/dyno-my-type-r-1388549/ For reference. I think you would appreciate some of his responses.
The second time was with his personal b20vtec, where it made 202hp on a DynoJet.
On local forums, he boasts about nationwide customers, and on Honda-Tech he talks about local customers; with the hope that nobody will ask any pressing questions about the how or why.
If he has done something else, I'm sure, he can easily post it up for reference.
I am more of a lurker on here, but I figured you deserve a response.
