Complete newb to SD. Little help please?

[the Dragon]

Can anyone tell me all the code/changes that need to be made to go mafless?

Keep logging -12.5 terms no matter what VE changes I make. Little lost here :(

Thanks for any assistance!

Usually the changes are under 'Engine Diagnostics' to disable the MAF. Are you wanting open-loop or closed?

You might want to post up your Tune. Every OS is a little different. For a general idea on SD open-loop check out this Tutorial..http://download.efilive.com/Tutorials/PDF/AutoVE Tuning Tutorial.pdf (http://download.efilive.com/Tutorials/PDF/AutoVE%20Tuning%20Tutorial.pdf)

Good luck..

Thank you so much!

I have one important question though:
Where can I get the wire to connect my Wideband to the EFILive cable?

Is it connected to A/F meter? I've got an AEM A/F meter.

If that wire IS connected to the A/F gauge, should I just disconnect it from the gauge and plug it in the EFI Cable?


Thanks again for the help!

That one is not exactly my specialty. A lot depends on whether you are going analog or serial. If you have EFILive's V2, serial connection is the route to go.

You might want to start a separate thread if you have an unusual wiring situation, otherwise there are tons of threads on how and where to get the cables..This thread has a lot of good material:http://forum.efilive.com/showthread.php?14942-Tried-to-make-cable-for-efilive-and-lc-1&highlight=wideband+cables

Try that out first..:rolleyes:..

[the Dragon]

Ok. I've got the first V 1.

So I guess my route is pre-determined as analog.

Sorry to bother you with these questions but, just so I'm on the right track, I need to hook up a wire from the Wideband in the exhaust pipe to the EFI cable and then a separate wire from the cable to the pc?

Or just the one wire going from the WB to the EFI cable?

Pardon the electrical ignorance :)

Dragon:

Like I said I am not the resident expert on wiring either. It took me about a half a day to figure mine out, but I went V2 and serial.

I would really check out that thread link I sent you or re-post a new thread. The forum gets a little slow this time of year, so you always get better responses with a new post than an older thread.

Check out that thread or do some searches. If you get stuck there are several wideband experts on this forum.

Good luck..

Any particular section I should post further questions?

Here's my tune BTW . . . feel free to correct any mistakes made :mrgreen:

[WeathermanShawn]

I guess you could try EFILive Hardware Forum. Your pick depending on whether you are V1 or V2. A lot of times you can just ask under 'General'.

That Tune should get you successfully into SD Mode. Looks like you will be SD Open-Loop. You might change B3801 to Disable.

Also, perhaps change P0103 to 'B:2 Trips, Emissions Related'. Then on your first log check your DTC'c. To need to actually get a MAF code to insure you went into SD mode.

That should work..

[the Dragon]

I'll make those changes. Then my VE Table changes should take effect at that point and become primary?

During warm-up what table will control fueling?

Thank you for all your help so far.

Searching a research is a huge part (which I've done a LOT of LOL).

But one will ALWAYS require assistance from experts like yourself.

Much appreciated!

Table B3605 will control the Commanded AFR not only at warm-up, but throughout all operating temperatures. You might double-check the AUTOVE Tutorial and make sure that those are the Commanded AFR's you really want.

Yes, your VE Table will be determining all of the airflow portion of your tune. Airflow X Injector Flow X Commanded Fuel etc...

You won't have the benefit of Trimming, so make sure B3601 is what you want..:rolleyes:.

[the Dragon]

I was told that this would be the most beneficial way to go SD for efficiency and accuracy.

Would you recommend a different route? Haven't done much so far anyway lol. I can alter the method :)

[WeathermanShawn]

No, your method is good.

I was referring to page 6 on the AUTOVE Tutorial..http:///download.efilive.com/Tutorials/PDF/AutoVE Tuning Tutorial.pdf (http://download.efilive.com/Tutorials/PDF/AutoVE%20Tuning%20Tutorial.pdf)

Just advising to check your B3601 vs the Tutorials..You can use whatever you desire..Just noting a difference..

Thanks again for the help!If that wire is the only output from the AEM, then yes, disconnect from gauge and connect to FlashScan V1 (pins C and D, or pins E and D; D is ground), then use the AEM calc pid for AFR and BEN.

Thanks for the tip! I'll look at it first thing tomorrow!
