ok ive been doing some reasearch before i buy my megasquirt kit. ive figure dout the fuel and im working on the ignition. i found a websit with some info on the gm dis ignition for the ecotec.
http://megasquirt.sourceforge.net/extra ... gmdis.html
i read through that but near theend it says....

The factory "domestic" ECOTEC uses an up-integrated version of DIS that included an ionization detection probe for "compression sense" - way too complicated for the MS to directly control BUT the VR sensor and 7X crankshaft reluctor is IDENTICAL to the older DIS models.

what does this mean? could i run an msd ignitoin and bypass the factory dis.

im workin on this myself. going to be running 2.2l ohv coil packs and ignition module. you should also be able to use quad 4 or 2.4 twin cam ignition module, but im not sure if the plug tube spacing is the same.
