peyton Posted January 25, 2014 Share Posted January 25, 2014 I have been doing a bunch of reading on the 83 turbo dizzy and megasquirt setups and I just want some verification that it's input voltage is 12v and not 5v reason being is my setup was getting really erratic spark I was wondering if I was feeding the dizzy too much power since there are two different vvalues to use for each voltage My set up is as follows Ms2 v3 Extra code Stock l28 83 dizzy and an msd blaster Dropping resistors for the stock low impedance iinjectors Quote Link to comment Share on other sites More sharing options...
Metro Posted January 25, 2014 Share Posted January 25, 2014 It's 12v with a 1k resistor, so it will be around 6-7 volts. Quote Link to comment Share on other sites More sharing options...
Dan_Austin Posted January 25, 2014 Share Posted January 25, 2014 The question is a bit unclear. The CAS does use a standard 12V connection to power the optical pickup. You also need the 1/4W K resistor connected to the output from the CAS to the MS. Since you mention the blaster coil you are likely only using the 'crank' pickup in the CAS, but if you decide to go full sequential you will also need a pull up resistor on the 'cam' output as well.

peyton Posted January 26, 2014 Author Share Posted January 26, 2014 Dan- I was asking because in the megamanual it states "for hall effect only-(EDIS, VAST, luminition, etc): a) Link OPTOOUT to TSEL Solder a wire between TACHSELECT and XG1 c) For 5V inputs fit a 470R resistor into the position of R12 For 12V inputs fit a 1K resistor into the position of R12" I went the 12v 1k route and was wondering if I choose the correct resistor for the trigger input.

Dan_Austin Posted January 26, 2014 Share Posted January 26, 2014 Gotcha. My unit was pre-assembled so I did not have to go through those steps, other than installing a pull up on the inputs, which was also a 1K resistor, so I think you are on the right path.
