In general the MS DC-DC converter is of a pretty poor (not robust) design, as is the Microsquirt VR sensor hardware input filtering/processing. I literally could not get Microsquirt to reliably pick up a noisy VR crank sensor (worked fine on a number of other ECU's). Universal 36-1 toothed trigger wheels. All our trigger wheels are laser cut from 5mm thick steel for the best possible sensor pickup and are compatible with the following systems:
LS1 24X “modified” MicroSquirt® ECU comes pre programmed with the “Sloppy Mechanics” LS1 turbo tune! This ECU has internal modifications to work specifically with GM LS engines. The harness is intended for use with the MicroSquirt ECU and fits LS engines with a 24X reluctor wheel using all factory sensors. If the crank sensor is setup such that the 10 th tooth after the missing teeth is at TDC, position the cam sensor such that it's between 110° − 250° before TDC on cylinder #1. This will create a proper position. This cam sync input can be configured as a Magnetic or Hall-Effect (Digital Rising or Digital Falling) input in the software. I have a sync loss /reset at 5000rpm. I have an ady bottom end with the stock VR sensor and stock 60-2 internal trigger wheel. The microsquirt has no vr trim and I've tried fitting a variety of resistors to the VR signal line, but this just moved the sync loss rather than eliminating it. Moved it down as we'll, which doesn't really help! If you are using another trigger source feeding the VR input circuit (say the EDIS PIP or some Hall sensors) the polarity may need to be changed, this is when they use the other op-amp output (VROUTINV) instead this polarity follows the VR sensor so a negative-to-positive VR sensor yields a ground-to-positive digital output.

I have a VR type crank sensor and I'm not sure how to wire it to the harness. Its a Bosch sensor typical on Mercedes cars. I assume one side is ground reference from the ECU then the output or signal is wired back to the appropriate input of the ECU.
Aug 30, 2019 · Remember I said way more features with this ecu compared to microsquirt? Here is the list of features: Four pressure sensor inputs if you use the internal 2.5 Bar MAP sensor which is good for 22psi of boost, for the MAP sensor. If you opt to use an external MAP sensor you go down to 3 pressure sensors. Feb 24, 2008 · This is the GTS1000 crankshaft trigger detail, the camshaft trigger is the camshaft lobe passing close to a variable reluctance sensor. If you look on the MicroSquirt forum, there is a link to the MSextra section. Hi all, I'm in the process of finishing up the installation of an ignition only Microsquirt V3 install. I'm using EDIS with the Microsquirt. Per the wiring diagram, I see the VR sensor shield wire connects directly to pin 7 (shield pin) on the EDIS connector. On the same wiring diagram, the PIP and SAW leads show a shield as well. The Microsquirt has 2 VR sensor circuits that are shielded because of this. I decided not to use a VR sensor because I did not want to deal with noise issues that a lot of people run into. And I did not need VR because I am not using sequential ignition which there would need to be one sensor for the cam and one for the crank. Hence the 2 VR ...
