Question on speed density

[LastCall]

Is the code the concern? Or are you trying to run a MAF tune? I would think that turbo would quickly max the MAF range without scaling it.

I need to run my MAF tune for a day and then flash it back to speed density!

Try the tune attached below. I adjusted many of the parameters back to stock, there were some very unusual things in your tune. PE fueling was set to stoich, idle timing tables were very high for such a small cam, injector flow rate should be a flat line (manifold referenced) unless you are not using the factory fuel regulator, etc. Do a compare and you can see the changes I made.

Do you have wideband? Can you go a log of maf freq vs LTFT or Wideband BEN?

Are you on PT.net? Your screen name look familiar.

There were a lot of things different than stock, there's a lot going on there...

as LastCall alluded to, it is best to start from stock and to edit only those tables that need to be.


Try LastCall's tune, and post some logs.

Hi Silly question - How do I open the .ctz file.

Its been over 12 years on the PT.net forum - seen quite a few mods! And you?

Thanks

The Ctz format replaced the bin format a few years ago. Sounds like you have an old version of efilive. There should be a "check for updates" in the Help Drop down menu. I would start there. And then check for updates on your BBX/V2 firmware in the eFILive scan and tune application. Those two things should bring you up to date.

Cool. I've been on there about the same amount of time. Since the days of it being a subforum on ls1tech. Time flies.

From V7 tunetool, go File->Open and select the .ctz file.


Or, setup your Windows to associate .ctz with the V7 tunetool, then you can double-click on a .ctz file.
