EBL Flash-II Tuning Out EGR?

[Majoraslayer]

I'm not entirely sure what I'm looking at on the VE tables, but here's a couple screenshots of the graphs if it helps to show where I am. It looks like a pretty consistent curve, but I don't know how to quantify if they're actually good or bad. I just figured out how to look at these graphs from a YouTube video.

I've attached my bin file (if the system allows it to go through) if anyone would like to take a closer look at my numbers.

The shape of your 3rd table for low speed looks pretty good but, you shouldn't need that much fuel @2000 RPM. Save it for higher RPMs/MAP The other 2 are backwards. You should be commanding more fuel as your RPMs and MAP go up.

Kinda like this 2000 - 6000 RPM table

FYI - I have my rev limiter set @5800 RPM right now...

SBC TBI rev limiter is 4,800 rpm on the trucks that had one. The stock valve springs start floating before you ever get to it.

Wow, Really? What, did they make them out of rubber bands?

How exactly do they end up backwards? I used the Vortec bin's tables, then ran VE learns off of that. This is without editing anything manually, so it's the result of the learns.

EDIT: Dumb question, but are you sure you're not looking at the graph values backwards? I spun the view around to show a better angle to see the shape of the curve, so the view itself is technically backwards. Here's the default view. Because of the 3D nature of it, it was hard to see the shape for the 3D curves at the default angle without moving it around.

Also, when I checked I also seemed to have my rev limiter set to about 5500. Either it adjusted itself during learns, or I forgot how I actually set it lol

Yup, that's backwards. VE should go up with load and RPM.
Sump'in ain't right! Post the tables instead of the graphs.

I'm starting to worry I'll never get this figured out. I think "it drives" is the best I'm ever going to get out of it unless I get some kind of engineering PhD.

It doesn't take a PhD, just some practice and understanding what you're looking at.


At your lowest demand box (20MAP @2000RPM) in the blue arrow you have a VE value of 61.57. In your highest demand box (100MAP @6000 RPM, you only have a value of 58.82.

Now, in this example, we have 49.41 and 79.61 respectively.

Now, if you flipped your values over, top to bottom, you'll have a properly populated table - low to high values at low to high demands.

How do I go about doing that exactly? Do I have to manually edit every cell, or is there a function in Tuner Pro to do that automatically after changing the high and low? I don't really understand how it ended up inverted in the first place.

Maybe go back to your original .bin from the EBL disc and run VE Learns again.

Did you copy a table from another ECM/PCM? Some of them are structured that way.

You can copy the values to a .csv and copy/paste 1 line at a time but, it'll still be way different than what you've been learning on.
