It’s been a busy spring even with COVID going on. I tore down our old deck in March. Spent April and May rebuilding the new deck. Also redid a bedroom upstairs that included making new furniture for it as well. It’s the guest bedroom/my wife’s hobby room. Here are a couple of finished pics. At least I am make progress on something... the DSM has been rather stagnant lately...

I did finally get an 8” screen shipped to me. Got my money back for the other that never showed up at the beginning of March. Maybe someday it will randomly show up at the house. Who knows. So I still needed a way to mount this to the factory bezel. So I 3D printed some small tabs to go around the outside and get super glued to the back of the screen and side of the bezel. Figured this should work pretty well vs tape that will get very gooey in the heat. Time will tell. Not sure when I’ll get this in the car but hopefully soon. Should look really sharp compared to the 7” screen.

Got the 8” screen installed. Need to tidy up some of my wiring in the dash for all this but it looks and works great. Now that I have more room on the screen I’ll play around with the gauge setup some more. Maybe move some off my main screen so that one isn’t so busy.

Finally had a chance to get the car out and washed for the first time this year. Earlier this year my hot start issues came back and I just parked it for a bit. Between other stuff going on and working from home because of COVID, the motivation and time wasn’t there. I got a starter blanket and a new starter about a month ago or so. Today was the first time testing it and it seems to have helped. Only time will tell. Hopefully it fixes the issue.

One thing I have just been living with for quite some time was the amperage draw of my radiator fan when it kicks on from a dead stop. It draws so much amperage when it kicks on that the car will actually stumble a few hundred rpms at idle. To combat this I would have the megasquirt add a few steps into the IAC valve a half a second before the fan would kick on. This would help a bit... but it’s a bandaid at best.

While doing some googling I came across some info that mid 2000’s ford cars had a solid state relay to control their radiator fans that takes a PWM signal. Basically this allows you to soft start the fan and ramp it up as coolant temp increases. The MS3x I run has plenty of PWM outputs and a few guys have already gotten this unit working just fine on other platforms. Luckily for me there are plenty of mid 00’s fords in a pick and pull near my job. I picked up two different versions but choose to go with the one that is known to work. Maybe I’ll play with the other one at a later date.

Basically you just have fused 12v power, ground and PWM signal going in and then leads to the fan coming out.

first step was to find a place to mount this. Ford had these mounted right to the fan shroud and based on the looks of it... it must get rather warm with the cooling fins and just the overall size and thickness of this aluminum housing. So I knew it had to be somewhere in the engine bay.... I just didn’t want it sticking out like a sore thumb bolted to the firewall or whatever.

a few years ago when I switched to this AFCO radiator I made up brackets to mount to the factory bolt location of the ac condenser mount on the upper radiator support. Already hanging off the driver side bracket is my Calan V3 catch can. On the other side I just so happen to have the perfect amount of room to mount this relay. Got another piece of flat stock, drilled mounting holes in it, welded nuts to the backside and welded it onto the existing bracket. Now that relay is tucked away nice and is still plenty easy to access. I still need to wire it up and get it working on the MS. I’ll post that up and my settings once I have it working.

Got the fan working on the new Ford PWM module. Works very well. Still need to test it on the road with the car running but it worked fine in the garage.

Ok - I'm curious now. What computer is driving these screens? what software is drawing the graphics?
