MAFT Gen 2 - Anyone? - Page 22 - 3000GT/Stealth International Message Center

Is it recommended to setup the lm1 like the lc1 where it's 0-5v not 1-2v as it is setup by default?

Hey,

What were your basic settings for the 560s? I just got em in and the car is running horifically, might be tune, might be bad injectors, not sure yet..

I adjusted my mainscale to -35 and fired it up (all previous fine tune settings were left where they were) Car started up ok, idled ok, but was "knocking" like you wouldn't believe it! LOUD!!

I then reset the GenII, setting the MAF in, MAF out, displacement, wideband, and the mainscale to -35

After a while of running like crap, the car now doesn't want to start, in the rare chance that it does, it dies pretty quick. still making the horrific knocking sound.

I did change the lower manifold and gaskets, and am looking into possibly tightening that, etc.. but as far as the tune, what settings did you go with right off the bat?

Thanks!

I usually do, it improves the signal/noise ratio.

How can I improve the sampling rate in tuner pro logging? I only got about 10 data points for an entire 2nd gear wot.

TurboBob · 07-26-2008, 03:18 PM

It should sample at about 10 frames per second.

How fast is yours sampling?

I would be interested in a complete tune writeup for the 560's as well I have those. 19t hl's, and using a 85mm maf with dajon blow through. With LC1 wideband. I Havent installed yet though till I fix all the vacume leaks. A good tune setup would be most appreciated.

I no longer have 560's, but may mainscale was at -36 if I remember correctly.
I always had to pull fuel in the High load page starting at 3K...all the way to 6K. Like a bell curve peaking at 4500....lo and mid I could pretty much leave alone...if anything richening in the lower rpms...
Take with a grain of salt, as you turbos are different....I have aTD04-16G set up...no HL wheels (yet)...

-36 worked pretty good for me....."knocking" doesn't sound good.
Are you sure the two are related?
Edit: Should start and run decent at -35 though...

Not exactly sure. I'm looking at the exported data from my session. This is on an 1/8th mile track so I'm only getting 1-2 with a touch of 3rd. I attached the csv. 2nd gear looks to be at around 1560. With 10 frames per second I should be getting more than only 10 frames for 2nd gear.

Here is the csv.

The knocking is something else.. not a good thing, but I won't get into that...

I just wanted to make sure I had a good setup on the GenII

Thanks, I will make my adjustments and use the experience I have had to get her right
