ECMlink setup going ok BUT could do with some extra advice as im going in circles i think (limited knowledge)

[FIBA M - EC17PSE]

Hey all im back and I have been trying to read up alot and it seems i been reading wrong as i started again from scratch based from ECMtunings data sheets and details but its not what the car liked and infact made it completely undriveable!!! I was on my way to get my inspection to make it fully road legal but i did not make it due to the bad data on ecmtunings site so im going to ask why they suggest those when its way off and wrong. maybe things need updating from when it was likely put on the site back in 2010 maybe.

so ecmtuning show most FIC injectors had dead times of 330 bar a few, so i decided to use that and sort global out to suit but i could not drive it without it going super lean and sputter!
So I started again from scratch and setup the injectors and adjusted them till LTFT was good, so global is now at -57.8 which is showing injectors as 1055cc??? and deadtime is set to 95 and currently this seems ok and i can drive it but im getting ever so slight lean LC1 reading upon small throttle usage but seems to level out ok but AFest shows at that same time it should be richer by 1 point or so, I seem to have combinedFT decent also but the LTFT and STFT seem to be cycling nicely around the zero mark so i hope im back to where its happier but this is where im stuck as i now do not know the best way to adjust (see below) if the global and DT are ok now it means fine tuning will be for SD i assume.

now currently I have not touch the SD charts as I believe I am understanding them wrongly. I based what i knew from jafros videos but i have been told differently so im here to confirm this also as I dont find any specific details on what the numbers do vs alterations which is kinda shocking since we have some of the best fine detailed threads going on the web!

so from jafros video he states air is fuel and lowering the number means less air and richens it up? but i have been advised that the higher the number the richer it gets. so is someone able to confirm this for me please



here im going to upload 2 logs. one from friday with there 330 deadtime as i read from ecmtunings site and the second is todays which is not alot of driving but it actually is able to drive better without running super lean (18+) from the previous log

small drive is fridays and un drive able and tweaked is sundays and driveable and no way near as lean.

I should note that from my previous posts on tuning i have gotten better cold starts and i am still tweaking them as im almost there now! its about 4 cranks to start and run rather then 8 ish and then trys to start and stalls so another few points on that will help out as its doing ok thus far.

one thing i CANNOT find out still no matter what is air smoothing in the DA section! everyones is different! what do you do to get this right? stock is based on the maf and is about 80 something % away so i did a rough calculation on mine and im about 20 ish % away maybe more like 15% but no matter what i do in this nothing seems to make a difference so why is this here and what do i really do in this part as it must be vital to tell the ecu how fast to react correct?

again sorry for the long essay on this, I want to get out all of what i have done in one message so i dont forget and its all readable in one post to be read over and not hlf the story missing etc

When you increase the values in ve table, you're making it richer. I see it goes super lean when you hit the gas. Assuming the injectors are good and none are stuck, try increasing the 0 value to 2 in BaseTipinTPSadj in DA.

Idle looks great at the end of the log.

So is the VE table fuel or air? Maybe thats why i was messing up assuming it was air? So higher number is fuel thats what i was told so thanks for also confirming. I must re watch jafros video and try to understand why i understood it wrongly.

The idle does seem to be wayyyy better now. I still dont get why my deadtimes are very low or even the whole thing since they sell them as 1200's now! I had them cleaned locally buy an evo chap and they were good to begin with but gave them a bath and got them a smidge better over them all for the machine he has. So i want to say negative on the sticking on injectors.

I read the tipin section so this adds fuel upon throttle! So when i adjust this from 0 to 2 this should richen it up and what will i look for as a result? Making sure the LC1 is not as lean anymore. If it needs more then 2 do i have to mess with any others or just see what TPSDelda is telling me.

I wish I had the smarts to be able to understand all this stuff.. Okay ... give me your brains before I blow out your wallet..

Im on a hard learning curve, when i think i got it going ok im hitting a brick wall not knowing what to do next or what i look for! I have gotten better but im still very new and cannot get out of dumb mode currently on this

When you increase the values in ve, it’s making the mixture richer, lower the values makes it leaner.
Don’t worry too much about deadtime now. You just want to set it so it’s drivable because once you set the global (after wot tuning), you’ll have to go back and adjust deadtime and everything for idle again.
I saw on your latest log when you blipped the throttle, it was lean. Increasing that value in tip in will injector more fuel. When you increase the value, look at your wb. It should richen up so it’s drivable.

thanks for these tips, i shall look at doing the minor adjustments sometime this week. im going to leave the VE table alone till i have some cruise logs and then i can do the adjustments based on those. i think for idle its not as critical until its all tuned upto WOT and then as you said idle will be readjusted again and so will the idle cell's in VE. let me know if im getting this plan wrong

Yup. That’s it Bobby!

 

[FIBA M - EC17PSE]

Yup. That’s it Bobby!

Thanks dude, anything else you think or see thats might need tweaking let me know. I watch and read as much as I can but i think sometimes it confuses me over cramming it in

Yeah will do. Just post a log any time. We’ve all been there. It’s a lot to take in all at once but the information is there and just take it one step at a time. It’s without a doubt overwhelming but you’ll get it. It’s just like seat time

some info is wrong as i found out and thats from ecmtuning themselfs listing deadtimes! so when they dont get it right and i follow them then we know somethings off! while the basics they do maybe right it makes me question everything if its useable as right now im questioning everything and just sticking to dsmtuners for the info vs there. I know its not the right way to think but its either wrong or old data that needs updating and if it needs updating what else does!

With deadtime & global, they’re only starting points since every engine/setup is different from one another. It’s a starting point that needs to be dialed in but shouldn’t be too far from that.

so you think once the final WOT tuning is done the deadtime will end up close to 330 were as now im currently set to just 95

Possibly. Won’t know until then but even if that is your final dt, that’s alright because 95ms vs 330ms is not a crazy difference in real time. I wouldn’t worry about it too much tbh

question on this DA adjustment comment, you said to raise 0 to 2 but its already set at 2 stock? do you mean raise it 2 more so 4 in total?

 

[AWD-Tony]

Yes my bad. Raise it to 4. Was 1at 4? If so raise that to 5

 

[FIBA M - EC17PSE]

Yes my bad. Raise it to 4. Was 1at 4? If so raise that to 5

yes thats all un touched and stock values. im just looking through the log and tpsdelta blips up a few times as 1 so i assume thats telling me this section needs an adjustment so i can bump those up.

thanks for confirming

 

[FIBA M - EC17PSE]

so this was the last log i did of the day (hours ago before my first post here) and did a small bit of driving up the road as i was trying to sort an alignment out the best i can and logged each drive. so i can check this against the new Tipin next time and see what happens. but at least i can actually drive down the road ok vs friday

Sure. I don’t have my laptop but when you blipped the throttle and went lean, tpsdelta was 0. Iirc 0 was 2 and 1 was 4, correct? If so, change 0 to 4, and 1 to 5

 

[AWD-Tony]

Part of the drivable issue is that it goes lean when you touch the throttle. The tipin should fix this.

thanks. im going to see when i got some time to do this and go around the block, depends how late i get home as its a loud car and too late i will be hated haha

Any time!! Haha I’m the same way and my car isn’t super loud. Post a log when you get a chance.

Bobby, think of tip in as an accelerator pump squirt from a carburetor. Maybe that just makes it easier to understand what it does. Your doing great!

on this section the tipin what do the numbers on the left mean from 0-8 mean? is it % of throttle opening? so the first 8% of throttle is counted. or am i not even close

It’s not percentage. I think it’s just a value given of how hard you press the throttle. You’ll see if you mash the pedal, it will give you count of 8.
