Biggest Duration @50, 95 LT1 24X with 0411 pcm

Whats the most/biggest Cam shaft you could run using the 0411 pcm?

[ElecTech]

Bigger than what 95% of LT engines out there would need, IMO.

Really very few limitations from an NA standpoint.

[ElecTech]

I've tuned LT cars using stock LT PCMs that were in the 240's.

My recommended cam is in the 280 @ .050, will the 0411 pcm work with that?

Sure. I would run the 1 Bar SD custom OS for that one. It has an Alpha-N base VE modifier table that will help gain some resolution in the fueling because you'll have very little MAP to work with. Also the 0411 is only reall good to a little over 8000 RPM. What displacement is the engine?

[ElecTech]

I should say that there is no table resolution after 8000, but I think it will still run the engine above that.

[WhiteMike03911]

396, it should'nt go over 8000.

[WhiteMike03911]

I've never tuned any efi stuff, I had a shop thune the car last time it was toogether with the 95 pcm and opti.

[ElecTech]

That seems like a ton of cam for a 396. I hope you have a single plane on it. I'm not trying to question your intelligence, but are you sure that is @ .050 lift? Is it a COMP cam lobe? That's going to be a pretty healthy combo for a first timer.

Where are you located?

[WhiteMike03911]

Single plane, 13:1, 300 shot, AFR 227, Bullet camshaft. Just first timer at efi tuning.
Located in Flint, MI.

[WhiteMike03911]

Also on E85

Just first timer at efi tuning.

That's what I mean. Definitely go with the 1 Bar SD custom OS.

Thanks for the info.
