So i recently finished VE learns on my EBL with a Wideband 02. Decent idle and no back fires with i floor it. AFR reading look decent.
I began my tuning with a 5.7 Vortec BIN. my engine is a 5.0

At this point all that i have done is VE learns. I have not messed with SA tables or any other tables.

My current setup is
1991 305 L03
with 5.0 vortec heads
5.7 Vortec .BIN (i had to fuse a stock L03 BIN with Vortec BIN. Not what i want but the best i could get )
long tube headers w/ true dual exhaust.
3.73 rear end
comp cams 08-500-8 cam

two questions:

What should i look at next to continue tuning my EBL

one of the only things i haven't worked on is the tranny. should i look into upgrading torque converter now? shift kit?

i feel like its still a dog when i gun it.

thanks in advance guys!

Not sure what you did regarding the BINs. But as long as these were EBL Flash BINs it is OK.

Did you copy the Vortec SA tables from the provided Vortec BIN? You mentioned that no SA work was done. If not that is why the engine is lazy.

Double check that the distributor base timing matches the SA - Initial SA in the calibration.

Work on getting the higher RPM areas tuned in. This is fueling wise.

I did do this. I took the SA Tables off of the 350 Vortec BIN and copied them to the L03 305 BIN.

I also checked the timing just to be sure.

When it comes down to smoothing the VE Tables, how should i do it? Do I smooth one number at a time or should i smooth a whole row at a time?

if i should smooth a whole row, do i smooth the RPM row of the VAC row? in other words, should i smooth the tables going left to right or top to bottom?

Thanks for the reply!!

Let the WUD do the VE table smoothing. It is the best way to go. If you want to force smoothing, can use the VE Learn function without even connecting to the ECM.

Just start a VE Learn, give it the BIN that you wish to smooth. Then stop the VE Learn, the newly created BIN will be smoothed.

I tried WUD with VE Learn without connecting to ECM. It did help a little but I think my tables are too rough that it would take a bunch of these to get it to smooth out.

This is what my current High Speed VE Table looks like. My Low Speed looks a lot like the High. When I start a VE Learn, I usually get the same areas being adjusted. I cant ever get the areas that show to be missing data.
I feel that if I could get it to do this, i could end up with a smoother table.

How can I force VE Learn to learn those areas?

Some areas are never used, while other areas are difficult to get data on. The PE/WOT areas can only be learned if a WB set up is used.

As for the high load, low RPM area, need to do some traffic crawl. An office or industrial park on weekends or after hours works for this.

The low load, low RPM corner is impossible to hit. This area just gets flattened to match above it manually.
