GammaE climbing fast
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

What processor and code?
Can you make a datalog, this will help us to see what's going on.
In MegaTune, hit 'Alt-L' + <enter> to make a datalog. Close MegaTune after a few minutes and the datalog will automatically be saved. It will be in your 'project folder', probably something like 'C:\Program Files\MegaSquirt\car1', with a name like 'datalog200602161303.xls'. Attached that file to a replay here.

wish i could, lance
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 with MS, but I ended up buying this dinosaur just to keep in the car and not worry about. I can't figure out how to transfer that file off of the laptop so I will have to go over to a friends house and have her do it and load it up later.
thanks

Yikes spikes!

What PCB are you using? What trigger circuit (VR or Hall)?
If this is a V2.2 board, have you added the Dave cap? It really helps in situations like this. There's more here: <http://www.megasquirt.info/v22manual/mwire.htm#ignition>

Cleaner signal?
(running the spark now driven by the dizzy, but not currently connected to megasquirt)
hall trigger I think
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 input appreciated...

Dave Cap and/or shielded tach wire
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

ground xg1
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
