Here are a couple screen shots of a log run I did. It is in two parts. Can anyone explain what is happening to my Vf signal and my AFR's are dropping to way rich and perhaps lend some insight as to how I can correct it.
Woooohooooo MAFT-Pro is running !!!
- Thread starter chriso
- Start date
in the first pic, it looks like the vf is tring to lean out the mix some, then as the afr comes up, it goes down to around 2.5v's and then when you went wot, it droped all the way, wher eim going to assume that the computer went into open loop, and stopped using the vf signal.
Hello, Doc....anybody??? Any other ideas on my settings that would give the above results? Thanks pimp for your thoughts but any idea what I do about it?

Add me where?? Chris you getting bad advise man...don't be adding me to your tuning... lololo

Certainly not WOT, maybe mid range. I never got past around 4000 rpms due to the fluctuation of my AFR's and I didn't want to do any engine damage.drjonez said:
there ya go.
part throttle is quite tricky as you are probably falling out of closed loop @ those points. it would be more helpful to have TPS + RPM graphed as well.

i would seriously advise adding you to any one's tune moe. :biglaugh:
I record data on tuner pro, but cant play it back! It says i have mismatched ads and xdf file. I have tpro4600.bin, and tpro4600.xdf on tuner pro page, It says ... \Program Files\TunerPro RT\522.ads for definition file on aldl setup page, what do i need here and how do I get it??
I was told to connect the purple wire on the MAP (6 pin) harness to the Vf signal on the ECU and to monitor this on the Aux 1 setting. Does anyone know if I am supposed to turn on Aux 1 Mode as described on page 15 of the manual by changing the setting from "0" to "1".
Come on MAFT Pro guys.....

It doesn't really matter, since all the aux mode tune settings are 0. (unless you changed them) (well except boost control.... you running that yet?)

Bob,
Well, boost control is set up but I'm trying not to run too much boost since I can't seem to get this thing to settle out. I've been driving very conservatively. I am still having idle and AFR issues. If I sent you a logfile can you decipher it for me and make some recommendations for the settings?
That would be awesome help if you could.
Also, how much are the wires for the timing control. I pm'ed you a while back but got no response. I thought they were free, or at least at one time they were.
I updated to 4.67 to fix a bad lean spike off idle (18-20:1), but now my boost controller does not work correctly no matter where I set it. It spikes to about 6 psi higher then where it is set with the same exact settings it had with 4.40.
I didn't know there was an update to 4.65 out yet. I looked all over full throttle's site but couldn't find it. Is it proprietary???? Malloy said he was running 4.76 (typo???)bigaaron said:
Aaron, were you able to get the rest of the AFR stuff to work through all the RPM ranges??? Care to share a *.bin file?bigaaron said:

Yes, but something was seriously changed from 4.40, so my 35+ dyno pulls worth of tuning were a waste of time because the tune is way off now, which is why I didn't enter the drag races at Vegas.
