ECMlink first timer timing is way too high

[Scoobystyl]

I just got my car running again and went for a little drive after tuning idol in my driveway, but on the drive my timing was going into the 30's even in boost, what should i change. Btw no knock when it was in boost and at 30* advanced

I noticed upwards of of 7psi on the gm3bar. You have a tremendous amount of work to do. It is so far out of whack. You really need to dial in your afrs and afrest. Its a mess everywhere. Your timing is fine, i mean you barely hit any loadfactor worth mentioning. which i have to say is wise considering how messed up everything is. Your global is a -56 and deadtime is over 1300usec, im not sure but that seems high. I have pte 1000s and deadtime is 440. You have 1550s but i wouldnt think theres THAT much difference. There has to be something off there. I dont know where to start. But, i was in the same boat, not quite as rough but we all start somewhere. Just do a ton of reading please and try to get your fuel, combined fts, and afr and afrest lined out before you go doing real pulls. Its all about studying link and getting the first things done first then working up. You have a killer setup capable of crazy high hp numbers. Nice job on that

edit: ecmwiki says for fic 1600s global is -72 and deadtime 450. Thats more like it. Unless you didnt mention youre running e85, maybe that would make more sense. Still the deadtime has to be off.

yes e85 that why the injectors are set the way they are, but deadtime did seem high to me also, ill have to do alot more reading whats making this so hard is speed density, when i was using a maf it seemed link did most of the work for you

 

[boost97gst]

I assumed it was SD. Yea that changes it from what ive heard. Makes it a whole lot more difficult to tune. Im a 2gmaf guy, know nothing about sd......yet. GL to you and im sure MY1G,sno,craig or someone will pop in and help

 

[Scoobystyl]

Yeah its totally different, i wish i had a working maf before i installed sd so i could use that to make my tables

have I dealt with you before?

No offence But, I know you didn't build those maps... . So who's maps are they

Why do you have dead time set that high? 1875 WTF Also why do you not now why it's set that high? Why is your AFR so Low? Or should I say why do you have EVO maps loaded if your running E85 ?

I don't see a problem with the timing... . 19* at 8 psi is not 30*

Looks like it just needs tune right if that wideband is set right your looking at 11:1 readings at cruise 13:1 under boost while targeting 11 or 10:1 WTF

 

[Scoobystyl]

no ive never dealt with you before, first time looking for advice. The maps are either calan, or turbosax2's base sd maps, from what id read they were both good starting points, deadtime is set that high to get the afr closer to 14.7 and it really just made it run smoother, is it really set that high? Are the evo maps whats killing my afr's whats a better starting point for e85?

Check around, theres a recent thread in the newbie section about e85 with a great link in it. 2nd post i think. The afrs for e85 are a bit tricky. Its weird, you have to dial down your globals(like you did) but the target afr iirc under boost is actually leaner than gas due to the higher octane rating. So you will be shooting for around 12 to 12.5:1 instead of the 11:1 you want with 93 oct. You still have work to do obviously but i would do some reading after you get things lining up right.
Im considering the switch to e85.... after i get this damn lc-1 issue worked out grrrrrrrrr.

There really is no VE "base-map" every motor is differant and it's not something that will ever work correctly using some "base" map in the aspect of things like a MAF and sensor specif ranges like what you do when you pick from the drop down menu the MAF sensor your using or calibrating a linear range like people have to do with there wideband(in regauds to MAP sensors) as it's not the sensors signal you're adjusting for But volmetric efficiency of the motor hence the "VE"... .

Anyway with out getting into that to much... .

Deadtime should only be set with aftermarket injectors In DA per PER voltage , If you having to add that much deadtime at Idle and you're that far off of your target AFR under any load I'd be looking at you global or Fuel pressure to be adjusting things along with your VE map(among other things)... . I didn't look to close at the log as some of the settings looked almost arbitrary... But, I didn't see the car Idling at all from what I recall it looked as the car died in the log trying to idle on it's own.

I'd shoot for setting you AFR under load closer to 11.4-11.8:1 range for e85 After getting things dialed in at idle correctly. As it is now if you where not running e85 going that lean you would be even worse off and setting the Target AFR leaner with out any other adjustment is going to just make things worse(even leaner).

You need to do quite a bit more reading IMHO. An Before making any more adjustment in link. As great a UI Ecmlink is an easy to make changes in there is still a lot to understand before making any changes.

As said above I'd start after doing so reading on E85 and some basic ideal gad law for SD and gettign thing adjust at Idle then I would do some reading up on E85, See here http://www.dsmtuners.com/forums/newbie-forum/59040-alternative-fuel-e85-ethanol-corn-gas-e70-beginner-merged.html and Here http://www.dsmtuners.com/forums/newbie-forum/372386-alternative-fuel-e85-e-85-ethanol-corn-gas-e70-advanced-merged.html

Keep in mind also if your Logged AFR isn't corerct your going to be having even more work and will literally chasing your tail going off of wrong settings... . Hopefully I didn't just confuse you more and some of this helps

That actually does help out alot, something that im having a hard time of understanding is, when running speed density how do you get you combined fuel trim to come up or down, if deadtime isnt fixing it?

Also in tables, ve,timing, etc, what does each column mean going up and down and what do the colomns going side to side

As I said you should do some reading on how Ideal gas law works and how your Volumetic efficiency relates to it... .

Ideal gas law

Definition-volumetric-efficiency

This may help little more in perspective as well Ecmlink sd101

 

[Scoobystyl]

Thanks for the advice, i also bought/read engine management advanced tuning, my biggest problem is im much more of a hands on learner, as i probably would have the gist of this if i had someone to help me through everything and explain why im making the changes im making, is that something you do when someone comes to you for services? or tell me how you do things.
