MS2 V3.0 in MP62 99 Miata

I've been wanting to do the MS2 for sometime now and finally pulled the plug. The easy part of the msextra manual is done. The board is now looking like this:
https://www.miataturbo.net/attachmen...ine=1430496374 Now the fun part. As I understand, for a 99 build, the ms2 need to be setup to control: Alternator VCIS Fans Cam and crank inputs. Since everybody has now switched to MS3, a lot of the MS2 thread picture links are getting broken and it is quite difficult to extract the good info out of it. For now, the most relevant alternator circuit i found is this: https://www.miataturbo.net/attachmen...ine=1430496374 And the best Cam and crank input circuit is this: https://www.miataturbo.net/attachmen...ine=1430496374 I was going to use middle led to control the fan relay as described here: Megasquirt 2 Mod Kits - Miata Turbo FAQ And the MK-RelayCtrl I bought for the VCIS. Next thing wil be to configure the board for PWM IAC with the MK-PWMIAC kit. Is that about right? Are there better/simpler circuits tu use? Does somebody have a picture of the final thing assembled for reference to manage Proto space? Thank you David |
return the ms2 cpu and case, buy a ms3 and expander board and ms3 case.
but there's no reason you cant use the opto and VR circuits for the crank/cam. |
Let's say I keep the MS2. Whitch would be the right way to use the opto circtuit for the cam sensor?
5.2.14.2 hall sensor / optical sensor 5.2.14.3 hall or logic sensor 5.2.14.4 ground switching |
goto this link it has a simple circuit Megasquirt Ii Opto Input Circuit - Forced Induction & N/A Power Mods - MX5Nutz Forum

I've got a 99, I need VR for 4 tooth crank wheel and opto for cam sensor. This circuit seems to be for a NA miata with CAS.

That link was if you were using the opto for crank and then built a second opto for cam. I don't like building extra circuits if possible.
