hey guys I need a little help, I have a 4.8 with a 625 cfm street demon and the edelbrock msd box with the chips.i also put the gm hot cam in her this winter,the msd box does not hook to the lap top anyways she runs great starts up cold, hot right away no problems but every so often she diesels a little bit when I shut her down. now if it had a distributor I would back off a little on the timing, so what do I do now

 

You can increase octane, but pulling timing is a thing that you should be able to do with a lap top. You need to figure it out. It would run better with a custom tune anyway.

 

What do you mean the MSD box does not hook to the laptop?

I thought the entire line of MSD 6ls boxes hooked to the laptop for timing setting?

 

He probably:

A: doesn't have a USB to serial adapter

B: has a newer version of running software that doesn't recognize the input

 

I bought the edelbrock kit 7118 the msd box does not have a usb port it does have some kind of a port it looks like the port on a computer that your monitor plugs into so if anybody knows what I can do to hook this up to a laptop don't be shy help me

 

I have this exact same cable for mine and it works perfectly.

plug it in while you are connected to the internet and wait for a minute or two and windows will get it installed for you. Then get the software from the website for the MSD box.

install the software, connect the laptop and box together, THEN start the software.
The rest is pretty much point and click. If you are NOT running a map sensor, then you will want to zero out the MAP table.

Made just for you!!

 

Running premium fuel or regular?
I have a boat that likes to diesel if it doesnt have premium gas

 

I do believe the box that comes with the edelbrock kit will only take the pills. it is not programmable with a laptop

 

+1

The edlebrock version deleted the serial port.

More octane is a sure fix. Timing like you said. Worse case turn the car off in gear or floor the pedal to get it to stop.

You can try leaning out the idle mixture. sometimes that helps. Colder thermostat too.

 

Have you tried all of the timing pills? Mine diesels with 87 octane I run 93

 

What is your idle set at? Perhaps it is just too high. You could also fatten up the idle circuit.

 

thanks guys I am just putting hi octane and no more problems, and yes I did try all the pills I really did not notice any difference. I put the GM hot cam kit in her this winter the car only weighs 2200 lbs and I am running 3.93 in the rear so I put the number 4 pill seems ok

 

Jesus, there would be some folks in serious trouble if my car was 2200 lbs.

 

Id like to see you in his car. "MGB" From seeing the size of you in your S10 video, it would be a tight squeeze at best. Lol.

 

I'm sure, lol. I know mustangs can get that light of you throw the cash at them for the light weight parts and gut everything.
