These videos are far n few where a person say's they messed up ....Anyway 99% of problems with MS are user error ...not reading ....etc...love your videos!
I have been watching your videos back to back for the last 5 hours tonight, the engine build was awesome!! Your Wiring is amazing! I just bought a 2001 Mazda Miata for $200 for my 16 year old Son and i am trying to learn as much about these car as possible, my miata is not running yet but it will be soon. New Sub here.
Yes sir that grounding instruction is like on the 13th page of assembly manual ! Right after the pages that tell you what should have been delivered with your new toy and the table of contents for the manual and a few other VERY important notices and notes mentioned before you connect and power the system up. Another good deal would be to use some device for limiting current flow until you're sure all is right with your system. Also an amp meter and a volt meter to be sure there is no Voltage drop or excessive current flowing through the power feed wires to the MS box. Fuses are nice too. They can save a lot of Butt hurt. I think it would be a good idea to test individual systems individually at first and not all of them at one time until you're sure of those also. The relay and fusing recommendations later on in the instructions show that there is room for additional protection and isolation of systems as well, page 17. Pull out some fuses and test first then test some more. You cannot have too many grounds, factory systems have grounds hidden all around the engine to body and frame. First from the battery neg. heavy wire to the block and then from the battery neg. to the body and from the engine block to the body with smaller wires along with smaller wires into the main engine harness to the ECM. Recently I have heard about fusing in even the grounding feeds with fusible leads along with the power feeds. There is a general rule about using fusible link, go 4 sizes below the wire size.
Yup I have a 3.0 here in my collection that had a poor ground. Owner tried a wire tuck, removed all but the battery ground, cranked the car and that was it. Basically the ground was going from MS to a body stud, thru the suspension, then the hubs, then the wheel bearings, axles, trans and eventually the battery ground attatched to the trans. I had a lot of time on my hands and tried to move all components to a prototype board and then gave up.
Thanks for sharing, you sometimes learn the hard way.... I'll defenetly be paying attention to detail when i put mine together, i don't really want to have to buy another one !!! :D
Grounds, grounds, grounds! I have a strap from engine to frame, battery negative to frame, and head to battery negative ground point. Then about 9-10 grounds coming out of the ms3 box. Everything that says needs a ground In the ms3 manual, run a separate wire to a ground block on the head. I have 2 ground blocks on my head for sensors and Ms3
the trubokitty instructions utilize the oem wiring harness. but you built your own harness and didn't have proper grounds on your engine harness (if I'm gathering that correctly). I don't think going out and buying a built fully populated board would solve that issue. The chassis ground and sensor ground issues need to be addressed no matter what! Your fried board looked like it had some cold solder joints but I'm assuming those didn't really matter in this situation. I'm building a MS3 myself at the moment. Thanks for sharing the vids. Hope it's running well now.
@@BuildingTheEXOCET I'm sorry to hear man, We all have problems with our builds and we can only grow stronger by pushing past them. I understand the struggle completely
Thanks for letting us learn from your mistakes! At least one thing good comes from blowing up the Ms3x
RIP Megasquirt
NICE! Haha. No offense but I didn't really want to help you guys out that much.
Takes courage to admit your mistakes and put them out there...good on you
Thank! But honestly I'm wrong so often I'm used to admitting it 😂
Hey man, appreciated! I hope you wouldn't face any other unnecessary loss again.
Thanks for sharing your experience. I’m going to be doing the MS3X on a srt4 in my 89 dodge daytona soon

Nice video, thank you for showing us what to look out for

This is how you learn dude. I'm new to this stuff but hopefully I'm not gotta blow too much money on the way lol
Agreed, just an expensive way to do it

Please can you elaborate on "having to do a new export-to" I am also trying to resolve a no spark issue on ms2
Thank you !

Ya the ground issues were my fault completely. I screwed up.

Fuck ...but you dont have ecu protections.fuses ??
Rewiring my car cost more then an engine rebuild, lmao
Speeduino it. You can fry it 5 times until your bank feels
Good vid
Wish I hadn't have had to make the video but hope it helps others
