ECMlink Need help getting WB correct/ LOG advice.

[Alpha]

This is my first log after a few hours of tuning.

I need to take away some timing to reduce knock, but other than that i think i am looking decent.

My only problem is the wideband, i cant get it to read correctly, no matter what i do.

I have watch all the videos, and followed step by step directions and still cant get it reading right.

I am tuning by looking at the gauge and making a mental note of the AFRs so i can adjust. I would be much easier to adjust fuel by looking at the log.

Also, any tips with my general tune would be greatly appreciated.

I'm really unsure (and kinda scared) as to what's going on with your fuel sliders. I would reset them all back to zero before something bad happens.

Looks like you haven't done any idle tuning, let alone jumping into WOT tuning. Have you read these two threads?

By looking at the settings for the "wb" item, I see you have the following:

0v = .86λ (12.64 AFR)
4.9v = 2λ (30 AFR)

So by having the above settings, your wideband will only display AFR's between those two ranges. Doesn't seem useful to me at all.

Have you checked out this thread? It seems to have all the info you need.

Yea i have been looking at those threads, and using them for reference. I am just so new at this, trying to learn the software is a little tricky.

As for the fuel sliders, I just installed 900cc injectors last night, and i was having trouble idling using the calculator in link( supposed to be at -50 global/330deadtime)
So i kept playing with the global until my idle was smooth and sitting at 14.7:1 on WB. Well, with the global at -37, the idle is great, however it runs waaaay to rich under boost, so i had to go in and adjust the sliders drastically to achieve the 11:1 AFR under boost. If i bring them back to zero, it pulls timing like crazy.

How would you suggest i fix this, without having the fuel sliders at -31?

Also, that video, is what i was using to adjust my wideband, however when i put in the values he was saying, it was reading 11:1 and my gauge was reading 14.7. So i just played with the numbers till matched the gauge, then i gave up in frustration. i will go back and change them.

Thanks

Your wideband appears to be setup as log a Narrowband output if it is infact logged on the Front o2.

If you have the AEM as in your Profile and that is the issue set the rotary dial on the back to PO or P1 it is likely on P4

Have you verified your fuel pressure is correct? Turn on the fuel pump via link (Misc tab) with the car off and check the gauge on your AFPR (hopefully you have one). Adjust accordingly until you have it set at 43.

Use the values from the calculator and zero out all your sliders. Yes, it will go rich under WOT, but that's because the factory AFR under those circumstances is around 9.4:1. You will ideally adjust this via the Direct Access (DA) tables. The same with any timing adjustments. You can start out by loading in the Evo 8 mod1 tables if you'd like.

You also have no MAF Comp adjustments which tells me you haven't watched all the videos from the ECMlink website. Otherwise you would have needed to adjust the low values to get your idle tune in check. The link to those videos can be found in "PLEASE READ" link I posted above.

Good point. The raw voltage is only going from 0-1v...looks like you wired in the narrowband signal.

Lol yeah I guess the other posibility is that you wired the wideband into another pin (like rear o2) thinking it was wired into the fronto2, and now we're just seeing the factory narrowband signal...

Yes, it is on p4 at the moment, i will change it to p0, and post a new log

As for the Fuel pressure, should the gauge read 43 with or without the vacuum line attached? Right now its around 37 with and 43 without.

I am in the process of tuning the idle/cruise as we speak, i will post a new idle log soon, and we can go from there.

Good point. The raw voltage is only going from 0-1v...looks like you wired in the narrowband signal.

I have the white wire from the gauge running to pin 76(front02) on the ecu. Should i change it?

Thanks for the help guys,

That is correct.

Don't need to as long as you have narrowband sim enabled in link.

 

[c2ypt1c]

Should i change it?

No, sounds like it's wired up correctly then. The rotary switch at p4 is most likely your problem. Setting it to p0 should output a 5v signal.

Just remember, the ecu is going to kick out of closed loop thinking it's super lean, because you don't have narrowband simulation enabled (in Link). Idle might be a bit rough for a few minutes...Therefore, to avoid this, I recommend enabling narrowband sim

Ok, I think we are in business. The WB is almost dead on to the log now, just need to make it perfect.

As for the Idle tuning, i am having trouble getting LTFT mid and LTFT lo to sit at 0%.
Would it be easier to use the deadtime and global adjustment method, rather than using the sliders?.

During this last log, my LTFT lo went from -3% to 8.4% and LTFT mid stayed exactly the same.

Here is a new log,( EDIT: Log is slightly too large to be uploaded, is there a way to make it smaller? maybe cut a small section from it?)

thanks

Select the region on the graph that you want, right-click -> selection -> clip file to selection, then save it as a new file.

Ok, here is the log, Thanks
