That looks pretty good IMO so thats probably not the problem. LOL. I just thought that maybe it had too big of a dip somewhere. A lot of guys run dips in their timing. Mine is very similar to yours except im up to 34

We were gonna add more timing when i got it running right and get time to hit the track see what it likes

07sick22

Tried going directly to the batt with the ground no change

Could the autometer monster tach be messin with the box by any chance??

I doubt it. Unplug the MSD box and look at the plug. Every terminal should be sticking out the same. If not, you may have a loose one that is not snapped in all the way. When you plug it into the box, it may be pushing the pin in and not making a good connection. I would take a pencil with a eraser on the end, and use the eraser end to lightly push on each terminal. LIGHTLY. You don't want to bend them. If one is not locked in you will see it easy. If you find one loose then take a pair of long nose pliers and pull it out. Be careful though. It doesn't take much. If that's not it, head to the harnesses.

I looked at it uesterday but ill double check it again when i get off work today was getting pertty irritated with the car so its very possible i might have over looked something. What would happen if the map sensor wasnt functioning properly?? Oh i also threw another crank sensor in there the other day just to rule it out

TTur1996

Don't get discouraged man. I know it sucks, but this is the crap that sometimes happens. When you do get it right, and you will. It will mean all that much more to you. Check those pins good. Sometimes its hard to see. That's why I told you about using the pencil to check them. Do you have factory harnesses for the coils? You may have to pull all the tape off and check the connections.

TTur1996

You don't know any one with another box that would let you try it do you? That would be the quickest way to rule that out. From what I read MSD doesn't get in a hurry if you send it in.

I ran mine at 36 from idle to 6700 the other day and it ran like a beast. I dialed it back down because I didnt want to melt her down or start hard but these motors love timing with the carb. Dont give up on your gremlin problem. Its probably something simple.

07sick22

Yea im gonna check the coil connectors and the main box connector when i get home. Im also gonna check the ground from where i cut the eye hook off the msd grounds to extend it to the front of the head make sure they didnt come loose i talked to msd yea there out of 6ls boxs til the middle/end of october so i pray its not the box god when its not having this problem car sounds so good just sucks and no i dont kno anyone around me with a 6010 box

TTur1996

Turn your map off for right now.

TTur1996

If you extend the ground. Don't use a but connector. Solder the connection. I even slide the plastic piece back on the loop ends. Solder them, slide the plastic piece back up then crimp. If its outside the car use heat shrink.

07sick22

Alright got rid of the crimp connection and just soldered the wires together also checked the coil packs and the main connector and added dielectric greas to the connectors also had a loose positive terminal fired it up and its not ideling the greatest still like 950 instead of the 1100-1050 its at when it sounds and runs good. I took the car down the street and made a little pull pulls good but still has the miss while cruising or moving from a light trued to launch it once had a carb backfire lol im gonna let it sit for a few mins and take it back out again. What exactly happens when you dissable the map sensor??

TTur1996

Your timing reverts to the chart you posted. How much compression do you have?

07sick22

Its a stock bottom end with a set of rod bolts. Ill post a video of it ideling in a min btw dissconnected the map and it started ideling better sounded good. So what is the purpose of even having the map?

TTur1996

Mine starts at 6 at zero and ramps to 34 at 600rpm and stays at 34 all the way. Doesn't make a full revolution and its running. Even when hot. Tried going higher at zero but the motor would spin about 6 to 8 revolutions before it would start. Tried all the different ways I saw on here and after a lot of work and a shitload of spark plugs. that's what I came up with. I had the stumble too, and after ramping clear back at 600 rpm it just came alive. And when you shut it off it just goes quiet. I'm not saying it will work for you but it might be worth a try.

07sick22

K im gonna try 8 at zero and disconnect the map im gonna throw the video up of it ideling and sounding good

TTur1996

Map sensor reads manifold pressure. I have never used one but they are used to put in or take out timing according to your manifold pressure. I have no idea how to set that up. But you can do that later if you want.

Click on the pic is should let you watch a video of it ideling
