View Full Version : New to tuning just want to make sure I'm on the right track?

I made a similar post on TGO and didn't really get a response. I have more info to add but apparently since I have such a low post count I cannot put links or attach any files. I will try to add more.
I have been trying to get my engine dialed in for the last couple of months. I was wondering if someone could look at what I have done so far and maybe give me some pointers? I seem to be chasing my VE tables around. It has gotten better since I went back to the stock injectors and added pressure. I recently added 100 to my injector offset Vs battery voltage that helped a little bit.

the issues/questions I have is:
1. Timing? the timeing table I am using is based off of one I copied out of a bin for a 2000 4.3 s10 with a manual transmission. Is this a good start? the machine shop said I needed to bring my timing in earlier and that with the compression I wouldn't need as much, but this thing is kind of a gutless wonder. I am not logging any knockcounts when I use DM to log, but when i use tuner pro i get a constant 44 knock counts with no KR. is this timing enough or should I give it more, or is it too agressive.
2. I can't seem to get it to operate in CL as the ecu thinks its rich and keeps trying to lean it out when the WB is already reading lean. I recalibrated the WB and still does the same thing. the factory heated O2 was moved with the hedder installation so I think that is where the issue is, but I am now simulating NB from my WB it still does it. I think it has something to do with Rich O2 Voltage Threshold vs Airflow, Lean O2 Voltage Threshold vs Airflow, and Mean Rich/Lean O2 Voltage Threshold vs Airflow. I tried to make a history table to maybe get an average O2 voltage reading and they are all over the place.
3. AE, it seems like any slight flux in throttle will cause AE to kick in. is this normal? I think this could be scewing some of my data since I don't know how to filter out AE and DE.

I have a 93 s10 with 2001 block and heads
TBI 4.3 with a built 4l60e
16168625 with $E6 mask
Moates Auto prom
Tuner Pro RT
stock 4.3 injectors at 15psi FP
Comp cam 266hr 112 LSA 210/215 duration at .050
1.52 roller tip rockers
bored .030 over with flat top -5cc pistons for 9.8:1 compression
ported vortec heads
edelbrock 2114 dual plane intake
long tube hedders
4.88 gears with 35" tires.
things disabled in the tune (or I think I disabled),
This is my first tuning experiance so I am learning as I go. I have read alot on this forum and TGO that has got me this far, but I think I'm to the point of information overload and having a hard time determining what applies to my setup and what doesn't. Any assistance or insite would be greatly appreciated. Sorry for the long post I just wanted to make sure I covered everything, hope i didn't leave anything out.

sorry for braking it up for some reason everytime i clicked submit it said I wasn't allowed to post links until 5 posts. I don't know at what point I can post attachments so I can include my bin and logfiles. I can email them if anyone would like to look at them and see my config.

DFCO - helps keep the vehicle from possible "bucking"... why did you disable PE?

It's not really disabled I just have it set to a high tps % so I don't accidently get into it while tuning. I disabled DFCO and DE because I though it was messing with my datalogs since my WB dosen't know when it active or not, but after datalogging last night without it I am still running into the same problem of having a bowl in my ve table at low map. I cant figure out what is causing this.
