I'm having problems getting the car to start. I've had my ms for a while now, but just got the confidence to install it. I've been playing with megatune for quite awhile. I kept reading about how you can only learn so much and then you needed to experience it, lol. Well, I thought I was to that point, I mean I've had this for like 7-8 months.

~It's a Version 2.2 board. I'm running 450cc DSM injectors, Aeromotive fpr, Megatune 2.25, only running fuel.
~I have my req fuel at 7.4 top and bottom, inj characteristics all at default, inj controls: speed density, 2 injs per cycle, alternating, 4stroke, 4 cyl, port, 4 inj, 250 kpa, and even fire.
~Cranking pulse 2.0, pulse @-40 6.5, @170 1.7.

My problem seems to be with the tach signal. I have it wired to b32 for the crank sensor(I get a tach signal on the MS. Also all connections are soldered), but when it is wired it also kills my spark. If I take it off and hook up the factory ecu to my injectors, I get spark and the car runs. I know the tach signal has to be connected to b32 but I tried the tach signal wire anyway but MS doesn't read rpms and my factory tach dies.I thought it was grounding out so I wired a new wire all the back to the MS. No luck either way.

Looking for some help, fellas. If you need more info, just let me know. I promise you I searched a heck of a lot, I didn't want to get flamed, lol nor look like a fool, but I think it's time for others insight, positive or otherwise, Thanks Guys and sorry for the long post.
