I've been looking around and maybe not hard enough for Megasquirt support. I've heard talk about someone possible selling VR sensor brackets and offering a trigger wheel installation service.

I'm putting the piece together to consider switching to mega squirt and it seems for various reasons the ford EDIS4 setup is a good choice. I don't know many people that could make the bracket or mount the trigger wheel and it seems to be to much hassle to get this stuff done on my own.

Also I heard talk about making the stock Nissan coolant sensors ocmpatible with megasquirt.

Is there anything going on with any of this?

The trigger wheel will have to be done by a machine shop.

Just remember put the crank pulley at TDC which is 2nd notch from left. Keep it at TDC and design where you want the VR sensor to go. It doesnt matter where you put it as long as the pulley is top dead center. After finding where you want the sensor to be take the trigger wheel and counting 9 teeth left from the center missing tooth thats where the VR sensor goes, so mark the trigger wheel and crank pulley.





Are you planning to keep P/S or A/C.

Anyways heres my write on MS.

As for using the OEM coolant sensor. This only works for Megasquirt II

It functions much like EasyTherm did for MegaSquirt-I.

IMPORTANT NOTE: Do NOT burn tables ('Calibrate AFR Table' or 'Calibrate Thermistor Tables') on a running engine. Even idle is NOT allowed, because these tables ONLY exist in flash, so once a table is erased, there is nothing but garbage in there until it is re-programmed, one word at a time. Until that reprogramming is complete, operating the engine is unsafe.

Thanks for the reply. Thats great that we can use the coolant sensor. I was planning on using MSII anyways.

I don't have to drill and tap my intake

I just wish I could use the CAS and COP. But I know this is not possible on MSII. Time to go find some escort parts

Chosen One,

I got a spare crank pulley and I'm going to take it down to the machine shop with the escort trigger wheel to see what they say. Can I ask how much your guy charged you for this? it should be like 50 dollars or so? Also where did you bolt the VR sensor bracket to?

Shouldn't cost more than $20. Its not like its a lot of work. I got mine done for free by the machinist for Marshall Space Flight Center.



Notice where Ive got the timing marks and the missing tooth lined up. Exactly like The Chosen One's. I mean it should, since I followed his instructions.

I paid $200 for mine, yes it sounds a lot but from what other shops told me its about right. It was $80/Hr for the machine work and it took 2.5 hours.

The place I went to was reputable so I didnt mind paying $$$$ to know that its gonna come out perfect. 2 years later and no problems.

You guys are lucky I had one of my co-workers do it for $90 bucks but he took a little while since he had to fabricate some equipment to get the work done. But my 240 runs with just the trigger wheel, sensor and COP. So far atleast.
