LS Motor Tuning

Someone wanna put on a school? Where's the best place to find info on LS motor tuning and modifying computers to run older transmissions ect.? I was looking at the cost of software and it seem quite expensive.

I always look to Moates first as they live what they do and are excellent with tech support!

I'm starting to get my feet wet with the LS PCM project. I'm working on converting an old school SBC to sequential EFI. The software is expensive! I'm leaning toward EFI Live software. EFI Live offers a demo version.

The '427 is an excellent PCM, which can control either the 4L80E / 4L60E and with some internal mods run port fuel injection in batch fire.

The '0411 LS VCM does everything a '427 PCM is capable of, but can be mounted under hood and is sequential port fuel injection.

The LS is very quickly becoming the next "replacement" engine of choice for the old school SBC. Quite often a vehicle project builder will decide to go with a good low mileage LS, instead of a "crate SBC". The LS has a real performance advantage over the old school SBC, and the LS has an underhood "cool factor" than many vehicle project builders are looking for.

It might not come as a surprise to the members of the injection section, but I support my auto hobby addiction the old school way of "buy / sell / trade" of auto parts / services. I figured I'd better get with the LS learning, or my source of funding my toy's will be less and less.

Doesn't the 427 come as an under hood version? I worked on a freinds 4.3L Vortec that had one and I thought it was a 427, have to look harder next time...

So here is an update on my LS ~ '0411 VCM progress. The list of things done is longer than the list of things to do.

Cool. I for sure wont be replacing my engine with another Gen1 if it ever fails. Factory HP and reliability of an LS motor is just too good to pass up.

I hate that I have so much time into my current engine and it's still no "waaaapow" motor.

I would really like one now but am gonna fix my more power fix with a doubler build asap. Still have more tuning on my TBI to do though.

Hey Dave, keep up the post's!!

I'm learning more every time you do. Next spring, I'll be 500$ a month richer, so I'm planning on efi'ing that Vortec with the Edelbrock 3505 multiport I've been sitting on since my divorce......I can't wait. I'm already drooling....Thanks for all you do.

3505
