Re: Fluctuating RPM: Ignition Box Tach Wire to MS2 Fuel Only

megasquirt201003041451.msq Dick I'm happy to share my msq. As a caveat I am far from an expert, as I only make time for the project in spurts, so it's hard to remember the details in between. The VE table is a combination of the default table (set up for a small block 350) and the table I had been ...

Re: Fluctuating RPM: Ignition Box Tach Wire to MS2 Fuel Only

Re: Fluctuating RPM: Ignition Box Tach Wire to MS2 Fuel Only

Dick, I saw your other posts and that prompted me to see if anyone had figured this out yet, since I'm not the only one with the issue. I meant to list my distributor, it's an MSD 8361: Pro-Billet with Vacuum Advance made for use with ignition boxes - it does not have an ignition module, the 8361 is...

Fluctuating RPM: Ignition Box Tach Wire to MS2 Fuel Only

I really, really hope someone can help me with this, I've put so much time into the project and learned a lot, but this problem is unbearable. I have a 10 to 20 RPM fluctuation that causes the engine to be rough at any steady throttle. The issue isn't noticeable when accelerating. MegaTune 4.00 MSII...
