i may start using Neptune now if calvin doesnt get back to where he was when he started. The short little comments i get in reply to legitimate questions just make me feel like i have done something wrong when i have been promoting his product the best i can. its a little frustrating when you feel you cant even contact the creator of the software you use the most without feeling like your being talked down to as if you are unimportant.

I have a feeling the old Calvin will be back soon

i sure hope so

btw, Don said that crank is the straightest one he has EVER measured lol

Thats good to hear, like i said it was minty fresh. I took 3 engines apart to get you a really good one, i'm glad it was worth my hassle and your wait. Now i just need to sell that damn 55mm main crank i have

Damn. I still havent heard anyone answer my topic title... "Why not NepTune?" But I have heard "Why not eCtune?", which I guess answers my question all together.

Joseph Davis · « **Reply #34 on:** February 10, 2010, 04:10:51 PM »

Yeah, they are equivalent on a lot of levels.

theidealone · « **Reply #35 on:** February 10, 2010, 04:52:19 PM »

Yea, it sucks really. Because I REALLY wanted to run eCtune. But Calvin changes that for me. I just ordered my RTP/Demon from HR tuning.

post up your thoughts after you try it.

i really like ectune once It landed on my laptop ive had no need to contact calvin, every question ive had has been answered by the tips in ectune

Thats how I was when crome first came out. Everyone seemed like they had a million questions and couldnt get this that or the other to work. Never really had any issues.

How important/beneficial would you say individual ign cylinder trim is? Neptune used to have it, but JR says it didn't work very well from his experimenting.

PhilStubbs · « **Reply #40 on:** February 10, 2010, 07:27:26 PM »

in my not so experienced opinion, individual ignition tuning would we good to have, otherwise you have to back all of the timing off for the cylinder that wants the most retarded timing leaving some power on the table. for street cars it seems silly though

d112crzy · « **Reply #42 on:** February 11, 2010, 01:31:38 AM »

Hey fag, you should test out how well eCtune's ignition cylinder trim works.

This is what JR told me about how it worked in Neptune;

Quote

I removed this feature after testing each cylinder with a timing light and seeing occasional variance, basically one cylinders settings leaking into another cylinder's ignition timing. It does this because the main loop where timing is calculated runs slower than the timer where it's applied to each cylinder. The timing value gets applied to several cylinders before it's recalculated and adjusted for individual cylinder trims again. Taking timing out of cylinder 3 where it's needed may also pull timing out of another cylinder... but adversely this also means it's possible that occasionally no timing will be pulled from cylinder 3.

You should see if it does the same or not.

i picked up 10whp with my old setup between corrections and no corrections. i ran into a hot cylinder, retarded timing in that cylinder and added timing to the map and picked up 10whp.

this was a 12:1 motor with stock cams/head on pump gas.

d112crzy · « **Reply #44 on:** February 11, 2010, 02:35:17 AM »

Yeah, I remember you talking about it a while back. I'm sure you've talked it over with JR, but does he know about your experience with eCtune's ignition individual cylinder trim? I'm trying to get him to put it back on.

Some cars require it.

eCtune's works perfectly. It is possible to rewrite the timing handler if the stock code doesn't work ideally.

I think the only thing that's holding neptune back a little from the other systems from my point of view is the lean protection feature. It saved my motor when my fuel pump went bad.

98vtec · « **Reply #47 on:** February 19, 2010, 03:33:47 PM »

i talked to James again and i got a little more from him about why he does not have individual cylinder trim implemented anymore:

"It doesn't work properly since the timer that fires the ignition is running faster than the code that calculates the final timing value. Values from one cylinder will sometimes bleed into another... which means it's possible the cylinder you want to pull timing from won't be pulling timing. I'm 99% sure the same thing happens with eCtune, but nobody has tested it."

Gaining 65 whp by retarding the two center cylinders 2.5 degrees isn't a product of imprecise control.

I take this was on an n/a k-series?

I just bought neptune on a demon rtp board. Really like it .This is my first time out but their are other companies that have auto tune. basically set target af ratio set a max cylinder temp an maybe they are full of shit cause that sounds way to easy. I could see it easily added to Neptune to perform because of the ease of navigating the software. there has been great thought an work done so noobs can go from start to finish on their tune. (make sure they add the extra 4 pin header to the demon board case you add stuff later.)

Joseph Davis · « **Reply #53 on:** February 28, 2010, 02:09:44 PM »

I've yet to see an autotune that worked correctly.

PhilStubbs · « **Reply #54 on:** February 28, 2010, 02:21:26 PM »

Am I the only one that doesn't understand why? It seems easy to work out if you have the ability to make software to run a car. It would be awesome for vac tuning

I can guesstimate the vac areas faster and better than autotune can/would be able to.

Besides, you're not learning shit with autotune. And if you've gone through the trouble of buying a wb, ostrich and burner, you might as well put some time in and learn how to tune properly.

Try hitting all cells. Try getting the autotune feature to filter out tip-in and tip-out trims. Try getting autotune to figure out what's going on with the engine when the sensors are glitching. Remove the intelligent operator from the controls who can use some redneck common sense and simple observation to notice that changes aren't having the desired effect, and replace it with a script that clobbers everything according to a statistical deviation that has nothing to do with reality.

The sort of person who wants autotune is the sort of person who doesn't know what's going on and shouldn't be fucking around.

MTZ · « **Reply #58 on:** February 28, 2010, 05:37:32 PM »

i tend to disagree, if your software knew the targetted AFR, and highest timing allowed (user would input it as a starting point for the software), temps, ect. i dont see why it wouldnt be beneficial to make a VERY close tune to what you want with an auto tune. JD you made it seem like it would be running all the time without human input well your going to be there monitoring afrs and you inputed the timing ( it could go south just like it does in real life.. but the software would be extremly conservative)

snm95ls · « **Reply #59 on:** February 28, 2010, 06:30:25 PM »

I have used an autotune feature once. After dicking iwht it for a while and letting it do its thing, it folled essentially the same trends that I observe and make changes for without it, all while taking about 5 times as long.

Just my very limited experience with it.

Anywho, anyone heard form Calvin lately? Still have a friend that cannot get a hold of him to get ectune working.

Disclaimer: I have not touched it to see what is going on since he needs to learn how to use it himself.
