I'll try that -- still trying to figure out the correct MAF range for it; I also lost redline flames when I added that little bit more fuel on the last revision.
There's no real way to tell if I need more fuel/air/timing or less fuel/air/timing for a larger flame than what i had before, right? What I had was the slightest little bit of orange, which is cool and all, but for all I know its inconsistent anyways.

I might be confusing things but seems like the revision prior to this one had 18ms of fuel compared to 17.5ms you have now. In both lc and hard cut limiter I’m running more fuel than you and I get bigger and more consistent flames with both so you probsbly should just add some more fuel. Also you’re at a lower elevation so you are getting more air so that should hint you might need to run more fuel than I am to match the higher air density you have in your area. I wouldn’t be surprised if there is calculated information of afr’s that help or hurt flames but I don’t know them. My guess is that your lc is pulling air at a rate somewhere about the 550-600 maf range which you seem to be targeting but you got to add more fuel if you want to see flames. I don’t know what your ignition retard for lc/ral is set to but you might want to mess with that too. Mine is set to -35 degrees

The only tune I have with the small flame is the screenshot from post 472. That's where I'm starting each revision from here out. Flame went away when I added more fuel & when I added a little fuel.
My carrier bearing broke so I'll be fixing that within a week hopefully -- until then I'll be ghost.

HI!

may I ask for some clarification on the 5 timer maps? I had the idea of replicating the short burbles in modern M cars and such, so I tried timered maps, but to my surprise the timer acts like a delay for ignition retard? fuel cut switch stays on zero in logs for the duration, but iga slowly walks down to -22 deg for example, instead of 'switching' to it early in the timer. is it supposed to act like that, or am I missing something? tried altering ignition change limitation maps to no effect.

I'm on 069.

(I'm competent in making cars burble and make flames otherwise, but this is confusing to me.)

Timer maps are supposed to delay trailing throttle fuel cut. Car will enter trailing throttle state, but will only cut fuel after timer expire essentially. There’s an ign map for trail throttle that you may not have modified yet that controls ignition timing on trailing throttle without fuel cut. I have never personally tried the timer pops but that’s how I presume them to work.

Yeah ms42 is a bit different than ms43 with the maps and it sucks on the bin that the parameters aren’t sorted. I’ve been working on sorting them for on my own but I’m not quite done yet, but once I finish that ms42 tuning should be easier for people just getting started


Mucho fuego es bueno.

Hey can u help me with ms43 tuning for gunshot like pops i get pops but minimal thx

Try enriching fuel injection for decel

 

[J&J Prestige]

Thanks so much man! Im still amazed I’ve gotten the flames this big. The tune I have has ghost cams and a vanos tweak for catless headers and intake with a modded injection map and throttle tweak. Tune is safe and I daily drive with it. If anyone wants the file I will share it if you pm me

hey R,
Hoping you can PM me the files ?
Wouldn’t let me PM you
Cheers

@mcollinaren I contacted you at youtube about the V3 tune im trying to get, maybe V2 i do not know which i like more. I got some flames working using pops & bangs mod with ac-off, gear 0 hard limiter set to 4000, using ignition cut hard limiter and both hysteresis set to 96. Got 2 or 3 pops with flame but not fast enough, if i set both hysteresis to 32 the little flames disappear and doesnt pop that loud. My LC is set to 2, RAL retard to -30.0. My tests are done with old sparks ill replace them today since 2 of them are bad and my car is running like a tractor. Below is my result, i did not change any
fuel enrichment related tables.

v3 and v2 were set to 4500rpm. the only other differences were the amount of ignition retard for the ral, but i dont remember how much I had. Also I had crappy spark plugs that were misfiring at the limiter which i mention in the video description and somewhere in this thread as well

Yes i saw you mentioned that in this thread. You wrote that you fixed it with some extra retard. When i have new spark plugs ill set the rpm to 4500 and ill test again. If not good ill post another video and upload my bin file so you can take a look at it. Did you also already find good settings using RAL in combination with LC? So that ignition cut is not needed, lot safer for the car😂
Oh and this is my setup btw:
Schmiedmann catless headers combined with their 400cell sport cats (mid car) and an novus rear silencer

You’re messing with stuff that will destroy your cats. If you want them deleted then that’s fair but I don’t think you do. You have to use ignition cut with or without the lc to get the results you want. I have settings that work alright for lc but I don’t think you’ll want them because they’ll melt your cats fast

Okay, thats good to know. I know this is bad for my cats but i assume the ignition cut is more friendly for my cats than your LC settings. I am thinking about making a small pipe i can fit where my cats currently sits so i can swap between them. That wont be a problem. Did you achieve the LC results using fuel enrichment? And does it work without ignitioncut? Also are the results V2/V3 like or is it totally different?

Btw i did not test yet since my coil on cyl5 is bad as well. Still a missfire on that one, it changes cylinder if i swap them so definitely a bad coil. Sparkplugs are new, NGK BKR6EQUP.

It’s all bad for your cats because it’s all ignition cut. Ignition cut is bad for cats. Ignition retard is also bad for your cats. Anything that causes combustion in your exhaust is bad for your cats.

Yes used additional fuel enrichment but also works without. you must get a hot exhaust though. Enrichment makes the flames bigger. Does not work without ignition cut with the little testing I have tried, but it might work with tweaks but won’t be nearly as loud or impressive.

Still not the results I am looking for. Maybe you could check my bin file and take a look whats wrong. check my settings for pops and bangs retard (ac off only), my hardlimiter settings and hysteresis. Everything else is done in the community patchlist. Currently it isnt popping very loud if its even popping. Its sounds more like a normal limiter. in the video I turned off the AC, hold the "-" of the cruise control and full throttle, I released and repressed the buttons 2 times in the video, seems to do better when I do. What i am looking for it your V2 or V3 video, loud pops with a little flame. I think i more like V2 since its a bit slower.

I reason your cats are the biggest issue preventing the results you want from happening. Cats do a good job at burning fuel trying to combust in the exhaust and as a result get very hot and melt when you are trying to shoot flames. I also went ahead and tweaked your tune a bit. Changed the launch control settings and hard cut and hysteresis. I recommend trying out both the launch control and hardlimiter with the RAL. I just made this folder, i think i will start assembling tunes in there I feel like sharing. public tunes - Google Drive

Nice, I will definitely try ! I let you know.

I still dont have the right results. However the pops do sound loud. In the video your tweaked file was used. Its another car but same setup, same engine but catless and still no flams only when throttle released at the end.

Maybe try -38 degrees and 4500. You should try your own tunes though. Worth more in the long run to do your own thing and not ask others for advise. I know what I did for those tunes, and even if you copy them exactly it won’t be what you want. So thats why I’m throwing out numbers.

Okay, ill experiment a bit and let it know if i have any success.

 

[JakeMarkus]

these are my values for a slightly more recent version of the tune with a little more fuel. Has two different 2-step things depending what im in the mood for. It also has an aggressive rev limiter that shoots flames and stuff. Think of my tune more as a template to do your own thing with. any of the changes I made can be transfered to other rpm ranges. you can copy if you want but experiment as well.

Would these values work on a m54b25? i see you have a b30 but i don't know if these values would only work with a b30 or not.
