See Dave Cap thread above

Datalog and .msq file

the Dave cap is in and things are a bit better. I am still getting spikes and resets, tho it starts better, revs pretty smooth, idles at 1200 and drives a little. Until I cure these spikes tho, it is really hard to tune.

Today I will attempt to get a trigger off my MSD6 box's tach adaptor signal ...

Dave cap installed, seems to run a whole lot better but still seem to have a few spikes and resets.

Have a look...

Hi Lance,
So if I ground XG1 today and install the dave cap when it comes, they will be fine together?

It will take a few days to get the part for the dave cap so I would like to keep working in the meantime.

thanks for responding
Bill

So does the Dave cap modification work along with grounding the shield from the tach wire to pin 25 and on to xg1?

or is it one or the other?
I was about to install a grounded tach wire (grounding back to xg1) but was unsure about the Dave cap mod (just ordered the part for that)

thanks
Bill

Can someone tell me if I can pull a clean tach signal off my MSD 6 box. ?

Right now I have the MSD Tach adaptor to send the signal to my 1971 Volvo Tach, so I was thinking of trying that signal to trigger ...

I am getting major spikes from my coil connection.
Which wire to use?


Yes it is a 2.2 board and NO dave cap yet
any ...

even tho I can't post my datalog, I can look at it and I did and WOW do I have SPIKES!
around 1100 it goes crazy, right off the top of the chart!

What to do?

MS-I 2.25

I sit here racking my brain for a way to get a datalog off this IBM thinkpad laptop.
My home network is Macintosh/Airport usb firewire etc.
this thing has none of those ports! Not even a network connector! Can't write cd's, only reads 'em.
I hae a USB to serial connector I bought to use my ibook ...

Hello All,

Just got my first MS vehicle started (VOlvo B20 2liter, 4cyl)
MS 2.2 megatune 2.25 fuel only

If I blip the gas and keep the revs up over 1200 or so it runs pretty good but if I do nothing the GammaE rises rapidly til it stalls?
Can anyone clue me in here?
thanks
Bill
