Just prepared the tune file, what's the best way to get a good set of data? Just gradually increase the throttle, using a lower gear on the highway? How high should I go on the RPM? How many % throttle max?

Since you guys are on the subject of doing the AutoVE, I just done quite a bit of work on my truck and am now preparing to do this. I have everything setup, but am at a standstill at step #16 (disconnecting the MAF, but still keeping the IAT signal to the PCM) because I have the 5-pin MAF. How do you go about doing this, or do you just disable the MAF completely and leave in? I have read that suggestion a number of places, but wasn't too sure of it since it is not mentioned in the tutorial. I have been reading/searching now for going on 2hrs and just can't seem to find the right piece of information.
Any help would be appreciated.
You could try leaving the MAF physically plugged in as long as the PCM throws any of the following DTC's: P0101, P0102, P0103;
any of those DTC's confirms SD mode (not OLSD, but SD; to confirm OL check that your LTFT's are always zero, but that is not related to what is being asked).
To get a good set of data, just drive around as you would normally, being aggressive every so often (lack of traffic helps)...
Try to get:
low gear WOT
low gear steady PT range (low-mid-high MAP high RPM)
high gear steady PT range (low-mid-high MAP low RPM)
Helps if your wife eyeballs the BEN map on the laptop in realtime so she can tell you which cells you're missing.
I thought in the setup you turn those codes off?Quote:

Okay, I'll try that. Thanks.
One thing I noticed while preparing the files ... on the tutorial, it says to use the backup VE table for 2000 models instead of the main VE table. Now, this one has a lower resolution and less range than the main VE table (15-105, 5 increment vs. 20-100, 10 increment) - what's the background on this?
OK, here's my result from the AutoVE-run ... took a nice long spin, was able to hit most of the cells on the BEN-map (based on the Backup VE) up to 6000rpm ... the NB O2 seem to be partly a bit off, but most of the KR is gone with the 15% increase on the base VE values ... anyway, most of the BEN cells are in the 0.85 area - which seems to mean that the correction of the VE table would then remove the 15% increase ...
Any comments on this data??
Seems like you used extra fueling to eliminate KR with the 15% increase on the VE table. Might want to decrease timing in the areas where you got KR and continue dialing in the VE table correctly.
Just a quick thought although I'm new to this right now and in the process of hooking my LC-1 up today preparing to really drive some here nuts with ?'s.
Then again, I usually learn quick. :cheers:
