I have a near stock manual swapped '93 SC400 and need a map to look at. Anybody have one I can use?
I'll be getting my ms3/x soon so this is very useful for me. Cheers
I have a few questions you may be able to help me with. First was which cam sensor to use but it seems G2 is the answer to that one.
I'm at work at the moment so I can't look at the map file yet but does it include the calibrations for the stock temp sensors? (I'm leaving the AFM in place to start with and just using THA signal from there)
when I get home I'll check this but, will I need to lay individual wires for the injectors or are they already in place?
Did you install the megasquirt parallel with the stock ECU to retain control of the other systems, and if so did you have any issues with sharing the sensors with it? I hear the temp sensors can sometimes be and issue.
As I say, I'll probably answer most of my questions myself when I get home. The difference in my setup is that it'll be completely stock otherwise including auto transmission. My stock ECU is dying and replacements are rare (I have a soarer) and I planned to get MS eventually anyway so I'm doing it first. Lol. I'll eventually install a GPIO as trans controller too.
Thanks

Thanks for the quick answers. I plan on using only the air temp sensor in the AFM but not the Karman Vortex flow sensor as I'll be using the MAP sensor as you recommend.
I have the UZZ31 1991 Toyota Soarer which is fitted with climate control, it only turns on the heaters when the coolant reaches a high enough temperature so I guess I'll loose that. I can live with that though, I'll just manually control it until I eventually fit a carputer which will take over control.
It's looking like I'm all set for the arrival of my megasquirt now, I can't wait!
Is it easy to get the vac tube through the firewall? I assume I just route it through the rubber grommit along with the rest of the ECU wires.
Do I just setup the Megasquirt in the default way or are there any resistor values I need to change? My research seems to indicate that it'll work with the standard values.

The Megasquirt arrived yesterday while I was at work and I've spent around 12 hours constructing it.
I just have one or two questions before I move on to installing it in the car. Am I correct in thinking I don't need any pull-up resistors for the crank and cam VR sensors? There are about six ground wires on my DB37 pigtail, do I need to connect them all into a single ground wire? Whats the point in having so many wires? I didn't install Q16 as I'm using the MS3X for spark output to my stock ignitors, is that right? What gauge wires should I get for the injectors to wire them for sequential?
I have the latest firmware so when I imported your map it complained that I had definition file 0095.000 whereas the MSQ file is version 0091.000, it imported still though so it wasn't a major issue, I'll just have to double check everything before I try it in the car as it may have lost one or two settings.
I jumpered JS6 and JS8 to SPR1 and SPR2 to provide a CAN connection later on when I get a Megashift, that was interesting as the MAP sensor was on the underside and a stack of chip holders for the MS3 daughter board on the top. I managed to thread the wires just under the daughterboard but next time I would use the Protoboard area to pass it through to the top.
Otherwise, it all seems OK at this point. Fingers crossed the rest of the install goes as smoothly, These things never do though so I'm not getting my hopes up. lol

I have the tune you uploaded in post 7 of this thread, my initial target is to just get it hooked up and running before I worry about perfecting the tune.
I have the MS powered on ignition switched 12V and grounded through the earths at pins 79 and 80 of the stock ECU. The NE signal works great when being shared with the stock ECU but it seems my G2 sensor is faulty (my initial issue with the car as stock) as it stops giving any signal after 3200RPM and, once warm, under 800RPM. I spliced the MS into G1 to test it works and I get a working signal but the stock ECU doesn't! It seems I can't share the cam sensor but once I fully take over engine control that won't matter.
Is there a value I can change to get it timed correctly with the G1 sensor or am I going to have to take it all apart and swap the sensors? I'm hoping I can use it as it is.
I'll be getting some vac tubing tomorrow so I'll be able to continue with the install. Is there a way to temporarily run injection on the standard 4 channels (wasted injection) as it's my daily driver so I like to do a bit at a time?
I you have a more up to date tune could you post it on here?
Cheers
Robert
