Gen 3 GM VE for dummies! How a cam can change Volumetric Efficiency

This video displays my way of looking at VE (Volumetric Efficiency) in a Gen 3 GM ECM. I explain the relation of VE to torque and how changing the camshaft will change the VE Table.

I’m trying so hard to learn. Watched a lot of your videos and some watching over and over. Thank you for putting these videos out. 👊

[@ericsmcmahan]

Matt Sanford, u r sharp. Thanks for posting. That was very interesting and I learned quire a bit.

[@adamthatguy454]

This is one of the best explanations I've seen so far. Excellent!

[@wheresmy10mm]

The torque curve guesstimate for ve adjustments in invaluable info. Thank you!

[@jonathanmarton384]

Can you show step by step on how to tune the VE table using data log

[@Matt_Sanford]

Yes. That video will be coming soon.

[@bluecollarhotrods9781]

That's what I need... I'm afraid to change anything until I learn the how and why.
So far I've gotten comfortable with changing shift points, recalibrating my speedometer after a gear swap, and now I "think" I have my efans sorted out to work properly when the AC is turned on.
Baby steps...

Honestly the best explanation and tutorial for VE that I’ve found in the last 3 weeks since I started my tuning process for my personal truck. Thank you sir!

[@Matt_Sanford]

You are very welcome!

[@CorEdmonds]

Yes.. He is good! I had to sign up

[@promobass77]

nice

[@ChevyDoc352]

Currently tuning Speed Density and was freaking out when I started seeing numbers go over 100 on the table, I’ve got an 05 Chevy 1500 with a truck Norris cam and 8.1l injectors just trying to dial it in

Been watching your videos since I got my mpvi3. Do you have any good ones for gen 3 scanner histogram explaining how to use it to tune the ve table?

[@jeffz6137]

Great video can you do one for the sloppy stage 2 cam ?

[@Matt_Sanford]

The video would basically be the same. The SS2 would just have lower VE down low and would have higher VE at higher RPM.

WOW
I can't wait to actually try this.

Thanks Matt this helped alot.

[@ohfugit]

Thanks for the excellent content!

[@charlesbaranski1860]

Any possibility you have a basic tune for a 6.0 LQ9 with the BTR Truck Norris cam?

[@Matt_Sanford]

I could make you one pretty easily. Email me at [e-mail]

[@Matt_Sanford]

You will need larger injectors though if it has the stock truck injectors.

[@charlesbaranski1860]

@@Matt_Sanford my engine has the 42 lbs injectors from a 8.1l marine engine. I wanted to keep the same injector plug with no adapters.

[@charlesbaranski1860]

Also tbss intake and a LS3 throttle body

[@1fast72nova]

Probably the reason your math on HP didn't match is because the peak numbers provided on the dyno graph weren't at the same RPM but on your ve table you use the same RPM

[@pjtherealdj]

Great video!

[@Matt_Sanford]

Thank you!
