Hello out there in TB land. Quick question/problem about the popular wasted spark conversion. The car in question is my 1990 765, of course with lh2.4.
I ordered the Buchka wasted spark board from the CFloMoTo website and it promptly arrived. Today I finally mustered the courage to actually solder on the teeny board, and inside my ezk (with tlao chip)
I have all the components to finalize the install, but I?m working out the mounting point for the coil and igniter. Today was pretty much wiring up everything, running wires out of the ezk etc. now although my car is currently an auto, I?m still wanting to use the launch control feature, as a future manual swap would be nice/ might happen I got everything completed, including a momentary switch for the ?set?, and a regular toggle switch for the ?arm?. This is when my problems arrived...
I tried testing the launch control at a modest 1200 rpm just to see if it worked or not, which of course it didn?t. Out comes the trusty voltmeter. At first I was thinking I didn?t solder something correctly so I checked the 1-4 and 2-3 wires, and found something strange. Both wires were fluctuating between 0-1vdc. I assume that these wires should have 5v at all times, or maybe even rhythmically between the two. Just for ****s and grins I checked the wires coming from the set and arm pins, and surprisingly found a constant 5v on both of those. Does anyone know where I screwed this up at...if anything is screwed up. I?m horrible with electronics, but something doesn?t seem right with the 1-4 and 2-3 wires. Will the launch control even work without the igniter and coil pack hooked up?
Thanks in advanced, fellow brickers, for probably bailing me out yet again!
