carbed ls intake and ignition box preferace - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I first looked into carbed ls conversions the only option was the edelbrock intake and msd controller. The more I read it seems the msd box has to much timing. What is the hot ticket now?

I saw the same read, but opted for the Edel intake /controller/1406 carb. On my stock 5.3, I don't see the issue? The old truck runs good, & will 'lite off" quicker than my 02 fuelie (warm)! On a carbureted setup, I would stick with a dual plane intake....especially on the street, for the low/mid performance. The Edelbrock controller is made by MSD.....however the MSD version of the controller has the option to be adjusted on a lap top. The LS is new to me, so I bring your thread TTT....& would like to hear more thoughts myself

The MSD ignition controller only has "too much timing" if you make it that way. You can choose between 6 different timing curves to better suit your application and if that doesn't do it for you, the box comes with a cord to plug a computer into the MSD ignition controller as well as a disc which will allow you to download their pro data software on your PC and with instructions provided (as well as a video up on you tube) you can plot your own timing curve and save it to a file as well as the controller, you can also run a two step rev limiter or a step retard for boost. You can also buy a harness to run the PN 6010 6LS ignition controller into a OEM Fuel injected LS and it will only alter the timing curve.

I have the 6010 msd box on a 6.0 . And it works great . I do use the lap top to tune with . In my opinion the pills are not the way to go .Thats like calling you neighbor up and asking what there tune is and using it. Every engine is different and will need to be fine tuned . The pills are fine for first start up and then throw them away . I would also encourage you to use the map sensor .

You can do the same exact thing as the dist setup . Just in a different way . Set base timing with lap top . The vac advance on the dist is replaced with a map sensor ( does the exact same thing ) . You can also monitor real time info while driving , timing at cruise , timing at wot , total timing at cruise with map advance , monitor when vac advance kick in or out and adjust . Also can adjust the timing at different rpms . Let just say you want a little more timing at idle to clean it up but dont need that extra timing up top and keep your vacuum advance the same in the higher rpm range .

In the end you can set your timing any way you want . The pills you cant . The msd has all you will need , just take the time to learn it .

homemade87, where were you when my LSx, c10 was carbureted? I went back to FI and called a professional to dial in my tune, which was exotic (LQ4, .030 over, Flat top Pistons, milled & ported 317 heads, .600 lift cam with 112 centerline). I felt the carbed version just didn't run right. But I didn't take much time to learn either. I wanted to pay someone to get right for me. I also didn't know much about carbs either. Homagemade87 is correct, take the time to learn and get it right. Clark.

I have a fuel injected motor and a carbed motor . I love them both . You can make a carbed motor run just a efficient as fuel injected . Its just that you will have to adjust fuel at the carb instead at the ecm . A air fuel gauge is a must for a carb to get it dialed in . Once you get that close you can start to work on the timing to get it fined tuned . If you are one to take the time you will be amazed how good it will run .

I do believe my carb motor has more power . It took me about a week to really get the feel of the msd box with some off and on reading and experimenting . Once I got the feel and started to realize I was doing the same thing as the old school set up but in a different way with more information and more adjustments in between with real time data it all came together .

I also have hp tuners for the fi tuning . Don't even think they are the same in complexity . Hp tuners is a totally different ball game .
