Does anyone have any experience with this new product? I want to use it with my digital 6 box basically to help control wheelspin off the line.

Is this illegal like the 7531 box with NHRA and IHRA?

we are currently working with the nhra tech guys as we speak.

and yes, myself and a few others have this unit and have been doing some testing with it .

ok - just want to make sure I got it - the box is illegal but you (MSD) are working with NHRA and IHRA to see if they will allow it?

MSD staff is working with the box to get practical experience with it?

Since both the 7730 and the 7531 box are illegal, who uses it? The 10.5 guys and ..??

we dont have an offical yes or no just yet.. so it is not banned ! repeat
IT IS NOT BANNED ..so i dont care what you read on forums..this unit has not been banned !

as far as the use of the box myself along with many other tech guys are avid racers .. from quick 8 to bracket racing......we even got some die hard circle track guys in here :001_smile:
yes, there are some of us here that have had the units and currently still using them ( one of the advantages of working here ).

and yes, there are some big name hitters that are currently testing with them.


what class do you run?

I am a bracket racer - IHRA no box and NHRA pro. I don't run a delay box and have a terrible time getting the car off the line. Pretty much the track mgmt does a poor job of prep. I break loose a 29.5/11 slick above 3500 rpm. The 7730 box looked to me to be the cure w/o having to back-half the car.

the 'logger" feature does not accept external inputs ..( like wheel speed-egt's--air fuel ratio's)--
it only records ..timing ,rpm, ( just like a 7531) .

here is another example:

a post made by our marketing staff:

Hey YB fans! We just wanted to clear up a few questions we saw on the thread here to help you all know more about the upcoming Power Grid system.

First off, there are currently NO plans to get rid of the 7531. It still has it's place!
Secondly, yes, the MSD-10 is being obsoleted. We will continue to service them though. We seriously recommend checking out the 8-Plus to anyone that misses the 10, it will cover pretty much everything.
Next, the Power Grid will work with all MSD legacy ignitions, but the rev limiting features will work much better on boxes that have rpm chip plugins (Original 6AL, 6BTM, 6ALN, 6M-2L, 6HVC-L, 7AL-2, 7AL-3, MSD 8-Plus, MSD 10 (obsolete), Mag 12 / 20 points box 8106, and Mag 44 points box 8147). This design was chosen specifically to work with ignitions that are not already programmable (such as the Digital-7 series). The 7730 can be hooked to those items, but none of the rev limiting features will work.
A few other bits: Yes, the Power Grid has a VNet connector right on it for a simple connection to RacePak systems where you can get all recorded data in one place. The 7730 is potted to aid in vibration and weather protection.
Finally, the Power Grid is on a VERY limited number of test vehicles right now, but will not be available to the public until the end of February or early March. Suggested retail pricing will go as follows:
7730 - Brains - 407.10
7720 - Muscle - 442.90
7751 - Manual Launch Control Module - 171.40
7761 - Slew Rate / Time Based Rev Limiter Module - 250.00

Good afternoon. Can you please help with understanding the new Poweer grid. If I buy the 7730 and the 7720 do I need any other box such as 7531 or do those 2 do everything? Do these have data acquistion and if so what does it have? Does the new Power grid have the "dots" option of the 7531? For a BBC Big Chief Nitrous Stock Suspension ride will I need the 7751 or 7761 either? Just looking at purchasing a 7531 this month but if these do the same thing if not more then I may wait. Will there be a wait to purchase when they go on sale or will there be a huge supply? Is there a way to pre-order now?
Thanks

all you would need to buy is the 7730 and the 7720. if you look a couple posts back.. you can see what the acquistion of the powergrid.


as far as the orders go on this system. It is first in...first out... so i would get my order in right away .

Thanks for the additional input - I don't plan on using the additional devices - all I want to be able to do is to back off the timing off the line and then have it come in after the tires hook up. Am I thinking correctly about this? I would add it to a digital 6 ignition..

is all this controled by timing or by soft touch rev contol
traction control
launch control etc. etc.
how well will it work for blown alcohol as far as the soft touch work part

Can MSD Post an example dqi file to review in the MSD ReView software? There isn't any examples in the MSD View distribution.

Also on another note - I don't see anything related to the 7761 time based rev limiter module in the current MSD View software 7730.mff file Is this something to be added as a new version release when you have it available or ?

Thanks... Ok, now who do I call to bug about how to figure out how to use ReView. You guys didn't put anything in the help files...

For example, how do you turn a trace OFF. I figured out double clicking on one will get it on, but if I do it again it just adds another of the same trace?

NEVERMIND ...

FIgured it out, just right click on the trace itself...

Thanks, John

Hi There,
I was just wondering what the small plastic collet/ferrule(?) is for to the left of the main plug on my new 7730. :w00t:
Out of the box it has a plastic stepped pin installed, should it stay or go?
Thanks, Dave, Australia.

i.c.t. ...that uses the fiber-optic lead 7555.

msdtech1955
08-03-2011, 10:29 AM
INDIVIDUAL CYLINDER TIMING
Note: To control ICT an inductive pickup, PN 7555, is required.
To accomplish timing changes per cylinder the engine’s firing order must be entered first. Firing order is
programmed in the tab Ignition Timing – Individual Cylinder – Firing Order by numbering the order into the
Value column. Many common firing orders can also be imported from a database within the software; to do
so simply go to FileImport and open the “firing_order” folder where an engine description can be selected.
Similarly, if an engine uses a firing order not included in these options the settings can be exported to be
saved in the same file.
After the correct firing order is entered individual cylinder timing can be created by editing rules. Up to 10
rules can be entered to control various aspects of timing for a single cylinder at a time. Each rule has six
(6) values that can be controlled; Cylinder, Retard/Advance, Timing, From Gear, Delay, and Ramp Time. To
make a rule the first four control values must be entered, Delay and Ramp Time may be left at the default of
0 if desired. When timing is changed on an individual cylinder, in order to bring the cylinder back to original
timing an equivalent amount of timing must be used to offset (DO NOT use 0°). I.E. If cylinder two is retarded
by 3° in RULE 1, in order to put the timing back in the cylinder must be advanced in a later rule by 3°.

Question about both - does this product have to be used with just a crank trigger or can it be used with just a distributor pick up (ex: 85501)? And is it capatible with HVC coil # 8251? Are all digital 7 unit going to be available in the future? Is the power grid unit taking over for good?

no sir, but if you want stable timing ...the crank trigger is the way to go.:001_cool:

is their a separate wiring diagram for this or does it wire the same as an MSD 8? Thanks.

msdtech1955
11-10-2011, 09:41 AM
would be the same as the 8....but...

1)make sure that you have all the zero degree chips in all four steps of retard on the 7al-3

2)plug the rev-limt from the power grid to the race limit on your 7al-3

3)also remember that ..now all your launch and burnout controls will be done through the power grid ( lt- blue and dark blue wires).

4) start retard, should be graphed on the powergrid also.

rcecarbldr
11-10-2011, 10:14 AM
I've got the box all hooked up to the 7AL-3 but I'm getting an Alert that says 12V Output error? What is that about since it's not shown in that exact wording on the installation instructions. Also just to be sure things are wired correctly. When I switch on the Main Power in the car the Box shows a green light, when I turn the "Ignition" switch on it goes Orange for a second then steady Red. Is this correct other than the steady Red? Also, is it required to use the Noise Capacitor with this setup. (This car didn't have one)Thanks.

Lastly, this engine runs a max timing of 35 degrees. Is this where I set the Max Timing Reference? It uses a crank trigger.

11-10-2011, 11:41 AM
No, not yet. Wasn't sure about the Max timing deal. And the pop up window on the MSD View software says "12V Output Error" when I turn the Ignition switch on. With the switch off it's Green as long as the USB cord is connected to the box and my computer. If I disconnect that cord it's dark with the Ignition switch off.

OK, It won't start. Does this Error message have anything to do with it? Prior to wiring in the 7730 it would fire immediately with just the 7AL-3. I get "Blinking Green" when I'm cranking it but it goes back to steady red when I stop.

Does the 7al-3 need to have all the "Zero" chips in the retard steps to just fire it up? I only have them in 1 and 2 right now as that was all I had in hand. More coming but won't be here til Monday.

Please post a sample screen showing on launch, retards -15 degrees from static which is 33* ramping in off release of transbrake over 2.00 seconds.

Also exactly where do I have control over start or ignition retard/rpm.

Simply stated Is Max Timing Reference the highest you want timimg ever to go?

Tried out that import curve feature in the 7761 setup, worked pretty good. I was able to build a driveshaft curve from a datalogger file, change it to CSV format and import it into MSDView to see the curve to work with. Worked pretty good!

One note for the feature wish list on software updates, please add a "ZOOM" feature for working in the Driveshaft Curve window. That would be helpful, especially if you're working on a small laptop screen at the racetrack.

Is the SPARKOFF feature still on the wishlist? I didn't see it in this last build.

Thanks, John

Beyond
01-16-2012, 12:44 PM
Well that was interesting... I think I understand now.

It appears that the SPARKOFF feature is something enabled in the .mff file, it's not part of the main program MsdView.exe, it depends on what release level .mff file you open, an old one or a new one.

So, with the new version of the software if you open the old (1st release) .mff file, it's not there. But if you open the latest 7730.mff , the SPARKOFF Feature is indeed there.

Glad to see it in there!

I think I'll get rid of those old .mff files so I don't get them mixed up with the new ones.
