Still working on the spreadsheet generator.

I had this weird bug where I could select a number of cells, even all of them for that matter, and the first value in the array would get dumped. No matter what I did, it only got worse. I eventually made it so bad I lost the abilty to reliably select cells. I couldn't figure it out. So I deleted a bunch of code, started over and approached it a bit differently. Now I can successful copy a table to the clip board that is pastable to almost any spreadsheet that accepts tab separated values. This is a huge step since my editor is a long way off from being able to have forumlas in the cells. I need to be able to cut and paste between google sheets and my editor because the vast majority of my math is done in sheets.

Pasting back to my cells is going to be a totally different matter.

I actually struggled quite significantly with assembling a multi dimension table. Getting the arrays to organize all the cells correctly proved to be difficult. Mostly due to me over complicating the solution instead of accepting simple answers.

More big progress tonight.

I added a bunch more ways to manage the selection process, added a clean way to edit individual cells. Copy and paste works now. There are still a number of bugs and things I haven't looked into, like if I try to paste a table that is larger than the available space... no idea what would happen with that...

There is probably another day or two of messing around with getting this spreadsheet/table to work correctly. Then I can combine it with my input validation, the single value parameters and start seeing what it can do.

Exciting! Also... I'm trying not to think about how much time it's taken me to get here.

Longevity V2.41 - Current

Data logs look good so far, though only a few people have actually updated to 2.41. This is an important update as it gets the turbos completely under control.

V2.41 is giving me the confidence to say, I believe I have the best tune for the health of our engines available on the market.

If you've been following along with this project, you like what I'm doing, then please support my efforts by purchasing Longevity for your truck! ~$315USD or $420 Canadian. Private message me for details.

I can get Nissan parts but nothing else yet.

That’s AWESOME news. Keep up the great work.

NOTICE!!!

There is a bug that I didn't catch until now. V2.41 will not turn on the fuel pump without the engine turning over. This is a critical flaw and I'll be releasing a proper fix as soon as possible. In the interm, I have made the stock calibration available. It is needed to prime the fuel system until the hotfix is released.

My sincere apologies.

Update

I have some appointments I can't get out of tomorrow. I won't be back on this problem until tomorrow evening. This is a bit of a massive undertaking, as there is nothing obviously turned off that would effect the lift pump. However, putting the stock calibration back on the truck brought priming back. This means an arduous task of going over every single parameter that has been changed and chasing back what those changes effect down the line. This could very likely take a few days to sort out.

So if you have to do your fuel filter change, you need to have the stock binary installed to prime the pumps. Longevity will not prime the fuel system. Longevity also will not give low fuel pressure warning, which at least gives me somewhere to look.

 

[NavyCuda]

Another Update

I'm just getting ready to head out for the day.

Some minor issues have been found in the calibration but nothing yet to explain why the lift pump is not pre-charging. I'm going to try it out anyways to hopefully eliminate these changes as a possibility. There are over 300 parameters that deal with low fuel pressure in one way or another. Some sensors were turned off that shouldn't have been and that might have an effect on charge flow, so I might have to go through a series of validations on my charge air/turbine maps again... oh yay!

Anyways I'm working on it and a solution will be found.

 

[NavyCuda]

V2.43

Well sadly, this has not solved it. Back to the grind.

I'm quite sad I didn't realize this sooner, but now that I know, it's obvious that the fuel pump isn't lighting up at key on.

 

[NavyCuda]

V2.44 FIXED!
Preparing HotFix V2.45

I need to make a few more tweeks but we found the problem. I will have the hot fix released a little later this evening. The problem was deceptive in its nature. It was one setting, that's usually related to fuel level reporting to the emissions manager, it seems Nissan uses it to manage the fuel pump when the engine is not running but the ignition is on.

When released HotFix V2.45 should be considered a mandatory update.

CRITICAL UPDATE!!!

Longevity.V2.45 - Current

Effectively drives the same as v2.41, but the fuel pump priming issue has been fixed. Some more small background fixes, improvements to cold weather warm up.

 

[NavyCuda]

Longevity.V2.45

I see there are still a few people running older versions of longevity. All previous versions of longevity have the fuel pump priming issue, please update whenever you can!

Editor

Well I am technically on my 5th rewrite, but just like with every other part of this project, each rewrite my code gets cleaner, shorter and my overall progress creeps forward. I've experimented with a number of different methods, I've had copy and paste working, selection by row, column and keyboard shortcut. Now I'm to the point that I can actually start feeding an array of different data types into the editor and it correctly generates the right parameter user interface.

I'll post a screen shot at some point, but right now it doesn't look any different than some of the engine document attempts I've posted previously. I keep juggling so many different projects but getting my editor working fully and properly is key to me making the next major advancements on longevity and to realize future opportunity.

Editor

Well I have made some serious progress. I know it still doesn't look like much, however every mock parameter is generated with data provided from an api server. I am now officially working on first, sending the configuration to the editor and then the combination of the configuration and the calibration. I want to be able to do things in layers, so for example all of the charge air settings can be one layer, all the egr settings another, all the dpf settings another, etc. etc.

However, before I can do that, I need to do a bunch of documenting. I'm going to make a blueprint library that I import into the react project and the api project. Previously each had their own blueprint, but I need to combine the blueprints into one document so that both projects can have access to each others type casting. It's a little overwhelming to be at this point, so I had to distract myself by making this post.

Business

The datalogs and reports coming back has V2.45 looking like a stand out. If nothing major needs updating over the next little while I might start pushing sales harder.

I'm also at a complete loss as what to use for a company logo. I know it's kind of ridiculous that I still have the profile shot of Stan as my avatar now that this is a business account...

 

[Two Yeets]

all the egr settings another, all the dpf settings another, etc. etc.

Are you making an emissions-friendly version, or just a spot to shove those tables under the rug?

Also, just make company logo a chicken. Problem solved, and your chicken gets to stay in the spotlight. Maybe the logo chicken can be carrying a wrench with his beak.

The emissions systems are everything that's wrong with modern diesels. If anything, I'm out to prove that a modern diesel can produce big power without billowing big clouds of smoke. If the regulators have their way, our days of driving internal combustion are numbered anyways.

I've thought about it. I don't think it's catching enough. I want to eventually have vinyl stickers with my logo, company name, etc, for anyone that wants to fly the flag. I'm not sure Stan stands out enough, handsome as he is.

Kory over at PPEI has perfected this over the last few years, so it’s definitely already been proven.

I have all of his tunes and the emissions in-tact tunes can makes just as much power.

Additionally, he’s figured out the tuning on Aisin transmissions, to include ours. He’s supposed to roll those out by summer.

I would love to see some ppei datalogs. I know a few other people have proven it too, namely banks. Yet, however, there are people that gobble up low boost fuelling tunes, when our engine specifically doesn’t benefit from that. A big single, or big vgt that is hard to light, okay, fine. Our engine and turbo doesn’t need that, at all.

I have not looked into transmission tuning at all and the way it has responded to changes in the engine calibration means it’s not a priority.

I'd rock a chicken on my truck. Might even give a rooster-themed name, like The Cock Wagon......wait a damn minute...

 

[NavyCuda]

You've certainly got me thinking on how to make a rooster work...

Editor

I've been busy doing errands and getting other things done... like servicing my beautiful truck. I've managed to find some time to work on the editor however. Made another big bit of progress.

I've not successfully taken all of the parameters from the ecfg and parsed them out according to the manager abbreviations. This is now in a nice big array, ready to send from the server to the client. I need to do a bit more cleaning to it before sending it out to the editor, then I'll be able to see if react can handle all 17600 parameters being displayed at once. Currently the document file is 3.4mb, which is within reason, since that's the same size as the calibration itself.

I'm really starting to see the light at the end of the tunnel for the editor. Yeah, it'll never quite be finished and I'll keep making it better, but once it's a useable tool I can focus on some other projects.

Just installed my longevity tune what's a huge difference! It's like a brand new truck again can't wait to put my 1st 200 miles on it. Sounds amazing running a FTE 30 inch resonator up front
