ms3 coyote v8 install (MS3-Pro)
Hello
I just finished physically installing a f150 sourced 5.0 tivct engine into my 92 mustang and am setting up a ms3-pro ecu. I also have purchased the MS relay board, a GM map sensor [unknown if this will be necessary] and (2) quad sparks. I have been following along with Ashford s build but have a few more general initial questions before I direct any specific software or application specific issues at individuals.
I have been using the pin description for the relay board which correspond to about half of the wires, I think, I will be using for this. The relay board instructions online state the referenced pin layout for the female db37 is for an ms1/2 install. Im assuming that the sensor leads, grounds, switched power, etc would route through the relay board in the same configuration for the ms3pro, correct?
For the shielded cables [crank, tps,etc.], Is there anything specific that needs to be done for the shielding [i.e. drain termination]? -Or can these be terminated onto the board/ sensor normally.
Im hoping to have the wiring done in the next few days.
I have not created any run files yet. For the future reference, where will I find the "MSQ" tag? This is my first Megasquirt install. My previous experience with this sort of install involved electromotive and performance electronics [FSAE, many moons ago]

Re: ms3 coyote v8 install
I think you may be better off wiring up your own relays and fuse box instead of the "relay board" - that's not really ideal for use with the MS3-Pro.

Re: ms3 coyote v8 install
How so? What are the areas you are initially concerned with?

Re: ms3 coyote v8 install
The relay board was designed for use with fuel-only Megasquirt-1. It is designed to use a DB37-DB37 cable that plugs into the Megasquirt. The screw terminals are likely to be unreliable if exposed to moisture (like most automotive installs.)

This is my personal favorite for MS installs. Gives you a main, fuel pump, injectors, coils and cooling fan option

Re: ms3 coyote v8 install (MS3-Pro)
I can deal with working around that type of issue. As it sits, all electrical connections that are non OEM sensor connections, starter solenoid or in a new weather pack will be enclosed in a "box" extending from the shock tower to the rear of the headlight mounting cup
Any feedback on the shielded wires?

Re: ms3 coyote v8 install (MS3-Pro)
For the crank sensor wiring I would suggest that you bypass the relay board totally. In fact as you have to make a harness up, I'd bypass it for all wires possible. e.g. MAT, CLT, TPS, O2, TPSVREF, SENSOR RETURN.Tripod02 wrote:For the shielded cables [crank, tps,etc.], Is there anything specific that needs to be done for the shielding [i.e. drain termination]? -Or can these be terminated onto the board/ sensor normally.

Re: ms3 coyote v8 install (MS3-Pro)
Engine is back in the car with custom oil pan and custom tri-y headers...It now fits
I just finished the coil and injector wiring. Now onto sensors:
Im a little confused on the cam position sensor/ phasor wiring. Im trying to take Ashford's suggestion about using all VR sensors to potentially avoid issues with the intake cam Hall effect units. Having taken the VR suggestion, [if I interpreted that one correctly] What are you using for the wiring for these?
Digital in? 1 to 3 and...?
medium current out? 1 to 3 and...? wires for spare injector? coil?
I am under the impression that there is only one built in VR conditioner for the ms3-pro Would I use this and 3 additional external VR conditioners? All external? Any suggestions on what VR conditioners to use?
I had asked about shielded cable in an earlier question about a month ago but Ill be more specific now. Does anyone think that using shielded pair [16/18 with shield and drain] would be necessary or at least helpful for the valvetrain sensors/phasors as far as noise control? If so, tie the drains to power ground? So far Im directly using the MS3 PRo harness and the factory F150 Coyote harness, which does not have shielded cam sensor wiring.

Re: ms3 coyote v8 install (MS3-Pro)
i am still using the factory hall sensors on the intakes, if i were to do it again i would use all 4 vr. i am not familiar with the ms3pro's hardware but am aware that there are 2 vr inputs 1 crank, 1 cam. vvt1 or right intake cam needs to be on cam input. following suit left intake needs to be vvt3 right exhaust needs to be vvt2 and left exhaust need to be vvt4. in tuner studios vvt2,3&4 can be determined by the drop down menus (only 4 available and vvt1 is locked to main cam)Tripod02 wrote:Engine is back in the car with custom oil pan and custom tri-y headers...It now fits

for the outputs just use at minimum a medium duty output the ouputs need a flyback diode i put mine in the oe harness a few inches away from the actuators. without them control is very scetchy and overloads the internal flyback( i almost desoldered/ fried the component on my ms3x that handles this runing it for a few minutes) the options available for output ports wide open meaning you can select just about anything available.
i would prefer shielded wire i just used a twisted pair as shielded wire is not readily available to me. i am also using the oem harness i just added a few to it and changed the plug as the same my last motor had( so i could just drop in my old one if i didn't like it with no rewiring) the twised pair on the factory vr sensors is good enough, the hal sensors shared a common ground and power with the rest of the harness and would need replacing if going to vr. for grounding the shield there are 2 schools of thought on this
1. grond at the engine block
2. ground at the ecu power ground
hopefully somone else will chime in on this either or is fine with me as long as it is grounded only on one side.
as for external vr conditioners you could get 2 external vr conditioners from jean belanger as it uses the same chip ans ms3pro and microsquirt. that would leave a spare to be used for vss
getting your setting right will take a bit of experimentation( resistors, which input polarity) i am not familiar with the ms3pro stuff and others may help better with it.
as far as gettig the cams to work this will need some expirimentation as well. for starters leave the phasers unplugged, getting a good cam comes second, get crank figured out first and a runnable base tune, the engine will run on crank sensor alone.
