MegaSquirt gurus help!!!

Ok so i have MS2 installed full stand alone and the car is running and has been for a week or so now but i have a couple questions


1) on the dash in TunerStudio the WUE is lit up green all the time, Thas is saying that its richn'ng the fuel for warm up right? should it allways be on?


2) Just today the car started going way lean right at take off and a light right next to WUE wend on and it said "NEED BURN" what the heck it that???

Ive been using the auto tune feature and its working great and i think the lean issue was caused cause i was using auto tune and was doing alot of engine breaking today and i think that messed up my VE table cause after a couple more trips around the block it was running right again

1. No WUE should only be on UNTILL car has reached Operating Temp. There is a WUE setting to tell it when to end your last value should be a few degrees under Op temp, and the value should be 0. That will shut it off right before op temp.


2. If Auto tune is running, its changing things.. it will say "need burn " because you have only updated the VE table, you need to burn them once you have stopped Auto tune..

3. you have a lot of reading to do.. these are questions that are addressed in the manual... msextra.com look up the tuning manual, read it, breathe it.

Also dont burn while driving. I am in the process of wiring ms in my boosted 420s.....now the tuning begins :/

I burn constantly... if you don't burn it won't save to the stand alone. Megasquirt is awesome but you need to do a lot of research before you start messing with stuff.

 

[SoCalK61000]

Thanx for the info guys. Yeah I have a TON of learning to do for sure. I dont plan in doing much tuning myself I'll leave it up to the dyno guy. But I do want to know what stuff means so I don't get ripped off and so I can make small changes myself.

@Glowryder I've looked thru that website and none of that stuff looks anything like my setup it makes it hard to relate that to what I have. Do you have a link to eggzaktly what I need to read?

And one more question. What should I set my req afr 2?

 

[glowryder]

required AFR? you mean req fuel?? what setting are you looking at? That site has what you need.. its not eclipse spacific, but that doesnt matter.. it tells you How the code works, and what / How to tune..

Google works bro..
Tuning Your MegaSquirt

You can burn while driving. nothing wrong with it, but try to limit it. Burn while at Idle and out of gear.
When auto tuning, the "send" changes it, so you dont need to burn every second.. just burn when your done..

Yeah I've seen all that but it's using megatons I'm using tunerStudio so it all looks different and a lot of the settings arent the same. As far as the req afr I'm looking under basic settup, engine constants, requierd fuel. There is a place for the afr what should that be?

 

[glowryder]

Correct they dont look the same. thats why you need to read.. They are the same code wise. just the interface looks different, so the settings are the same.... It will tall you in the manual what that needs to be, IIRC its 14.7 if your using gasoline.. The definitions of the terms is what you need to focus on, not the pictures..

 

[Josh97eclipse]

I was told not to burn while im cruising because it will mess up the VE tables etc. I wish someone was close to me to give me the run down on ms in person.

you and me both!!!

ok so ive been reading and reading and reading and some questions are answered BUT no matter what i do the WUE light is allways on car runs good tho

 

[glowryder]

Go to your WUE table, when (What coolant) does WUE % = O?
Whats your Operating temp?

Once you fix this, your whole VE table will be leaner.. so youll need to re-tune. Sorry. thus why its critical to get the Warm up stuff correct before moving on to tuning, like it says in the manual,.. now youll have to do more work..

You can burn while IDLING. shoundt burn with load. The tuner i use, who does most of the Neon MS's and is running 40 psi himself, does it with no hesitation. I trust him , as hes been tuning MS on 420As for a long time.. You dont want to Calibrate while driving..like cal TPS.. that will get messy..

well thats the problem my WUE never goes to zero it stops @ 113.2* and 80%

If i move it to zero the car will not idle at all, when i move it it also moves my IAC steps

 

[glowryder]

Wow. You have alot wrong..

1. Why isntbur coolant going above 132you defrees.. thats nkt operating temp..
2. Wue should be at minn 100%. 100%=0. So 120%the =mopar 20% addtion over your ve. Some how your leaning out ## ve you need to TUNE your idle bins befor you even start duing wue or even think about iac settings. Get the car warm, seems like you need to add fuel. Get to op temp which should be 190*. If ## really at 132*, you got an issue. Did you correctly calibrate ## thermisters?

Ono sorry my operating temp is 190* the WUE table stops at 113 and is 80% I changed that value to 100% and wue is no longer lit up. So now it's off. My VEE table was way rich as you said it would be but after some tweaking all is good. I didint know that 100% was off I figured 0% would be off. Still working on tweaking my idle a bit I have Evo correction off below 1300rpm and my idle is at about 1200ish any lower and is stumbles really bad. It's got crower stage 2 cams

 

[glowryder]

my EGO works in idle.. Tune the ve cells in Idle, and set the ego to work for idle so that it can copensate for baro and air temp diffs or your idle will always be messed up. WUE needs to end at ~185 then if Op temp is 190. SO 185 NEEDS TO = 100. then go up from there, so like 132 going to = 115 or something to that effect. I have the same cams. My timing in the idle bins is about 15 and ~1000 rpm to help stabilize idle and i run at ~ 14.4. butim also seqential so i can idle a little better then batch fire

Ok cool got it, changed to 180 and all is looking good idle is down to right around 1000 witch is ok any lower and the cams dont like it


turned the EGO on at +400 RPM's the idle is a little lean (I think) its at 14.5ish and then goes to 16.5 sometimes but richens right back up

 

[glowryder]

Your idle shouldnt be that lean with EGO on or off. Typically you tune Idle cells with ego off so that they stay in an ~ .5 AFR range. then EGO controlls that.. your asking ego to correct alot.. thats not tuned.. Whats yout timing at Idle? perhaps lower that..

 

[Josh97eclipse]

Wow all this makes me not want to wire my ms in.....maybe i should just wire it in and get used to tuner studios and it will be more clear.

 

[glowryder]

Its really not that difficcult.. reading the manual and understanding how it works and what things do is key..

Ok I was thinking that wasant good timing is @ 10 degrees at idle.

If i turn EGO off at idle my AFR hangs at about 14.3-14.7 at idle bit with it on thats when i get that occasional dip to 16.something.

Dont do that its not that bad man, just alot of reading and learning. Glowrider is a smart dude and has helped me out before on some other stuff so listen to what hes saying here i just wish he lived close to me

one of my biggest problems is trying to do all the reading from my phone at home cause i dont have internet right now, and i can only sneak on for limited times while im at work


And about the manual, i wish it would use tuning studio for the references cause some stuff isint in the same spot in studio VS megatune and that really messes me up

 

[glowryder]

Yea the Megatune part sucks, but There is one somewhere that explains what everything is. The manual is a quick nasty. Reading form your Ph sux.. sorry bro. Im stil alittle concerned about the 16 Dip. that means some where a bin is too lean. Are you watching the yellow dot on your VE table? Watch to see where its at when you get the 16, that cell needs adjusting. 10* is low, but ###### fine to give you a really stable idle.

 

[Josh97eclipse]

What should I read first

 

[glowryder]

Tuning Your MegaSquirt link above.. Its going to refernce megatune, ignore that. Just focus on what ther perameter is, like WUE etc, and focus on how it works and what the valuses mean. Open Tuner studio, and poke around finding all the perameters mentioned.

 

[Josh97eclipse]

Thanks a bunch Glow. A big help to all the 2gnters :thumbup:

 

[glowryder]

np. READ READ READ! thats all i can say
