My SDS temp sensor is right next to my temp sensor for my stewart warner gauge.  The stewart warner gauge sits at 190-200 cruising and/or sitting while the SDS reads from 158 to 176 back and forth.  Since I don't have the stock temp gauge hooked up, I can't tell if 200* is normal or not.   ???  And why does SDS not read closer to aftermarket electric gauge?

for some reason I cant find the thread about this... we can use teh 1g radio adapter harness when installing a new radio right? someone chopped  my pigtails off and I have another one coming so I cant tell yet if the 1g adapter harness will mate up.

I'm looking to get my 4E reflashed with the current updated software.   01/11/05 Version 14 Software Release for EM-3 Systems   V14 software for EM-3 systems is now available as an upgrade chip which you can install yourself. EM-3 systems cannot use the nitrous or a/c functions but have the AFR data logging capability. Changing the chip will involve writing down your existing values and transfering them to your new chip   SDS is offerring data logging WBo2 readings...look how slick that is...

I have hooked up my EM-4D system (no ignition control).  No i,m trying to make the stock ignition work with the sds.  I have supplied kO pwr, and gnd to the module and ran wires from the detonation sensor to the corresponding wire on the module, as well as the black and white wires from the distributor to the module.  Now I believe a few wires can be removed (ones concerning altitude adjustment).  Now does the black with yellow tracer wire coming from the distributor signal generator need +12
