  1. Yeah looking at MHR's engine bay pics is straight 13b pornography.
  2. This is the main reason right here. I ponied up to buy the racing beat pre-silencer with the rationale that since it's made for the job it will survive right behind the header. So, while I reaaaaally like the idea of flames on decel ultimately I just want my exhaust to last since it is mainly just a daisy chain of mufflers welded together. Ugh, I can't even imagine how frustrating that must have been. I have been waffling as to whether or not I feel like cutting a vent in my hood. This may have sealed it for me though. Any way to get heat out of there. Nice mounting BTW. I also have a GM sensor but it spins the wrong direction so I have to mount it on the throttle cable side, which is crazy annoying. Also the drive type is just those two little triangle nubs, which is also crazy annoying. This is why I bought the ford one, because it is a slot type and more or less fits in the end of the stock rx-7 throttle shaft. I just can't keep fabbing up random bric-a-brac every single time I need to do anything. I work in a single garage with no bench space, no room, no place to sit... I'm not complaining but from a simple time standpoint it's just not efficient to sit cross-legged on a carpet remnant trying to dremel out some sort of adapter all day. Sigh.
  3. Thanks for posting the pics. Interesting that the tps has just the two tabs and the shaft drive is flat spade type. guess I'll just suck it up and cobble something together with the tps I have.
  4. Wow, Thanks for the offer. I am not really looking for a specific year as long as it has the rectangular slit type shaft input. I wouldn't necessarily mind paying for a $50 version if I thought it would be a nice sensor. If it seems they are all pretty flimsy maybe I'll just try it out and see what I get.
  5. Trying to find a TPS that fits my rx7 and it seems the Ford type with the slot fits the best. So I ordered this one from Amazon. ...Now when I say this is cheap, I mean I literally couldn't wrap my head around it. Whatever it's made of is fascinating because it has no weight to it. There is just no substance. And the dial section in the middle doesn't even seem to be attached to anything? It just rattles around and I can kind of pull it half way out. It also doesn't turn well, it gets hung up and kinda clicks around. This might be fine but it doesn't even seem to be turning any sort of mechanism? Did I get scammed? I am seriously perplexed. It's insane. I haven't tested it since I have to make a custom bracket and didn't want to bother with this insane garbage sensor. So, is this just a cheap 3rd party TPS? If I spend $50 on the same sensor will it be a solid unit that spins well, or is this just what a Ford TPS is like?

    EMI Shielding question

    Not the threaded, its the little black plastic one with the mounting tab. I got it specifically because it has a pullup built in.

    EMI Shielding question

    I did pretty extensive testing with the JimStim (ecu stimulator board) and checked most of the signals with an oscilloscope. Fingers crossed it all seemed to be working how it should. Hall sensor is the one sold by DIYautotune (company that sells the megasquirt) so it should be optimally compatible. It has internal pull-up so no need to worry about that. Another 20 hour wiring weekend and I'm very close to finishing up the wiring. On the plus side my soldering skills have improved 100x over the past few weeks 🙄

    Moved to S4 intake as well. Can't wait to get it all running and out on track.

    EMI Shielding question

    Yup, I have run all new GM sensors and switched to 4x420cc rx8 injectors. A lot of work up front but hopefully will make future maintenance easy.

    I am starting with GSL-SE motor so I am using trigger wheel on the front pulley. More than hoping it's the best money I'd ever spent I am hoping it's the best for the amount of TIME I have ever spent. I am easily 10,000 hours into this project. First timer, but still... sooooo much to do. That would be fantastic if you would. Motor is GSL-SE with a large street port, which I think you have a slightly different setup but should be close enough. At least give me a better base line.

    EMI Shielding question

    Thanks for this. There is A LOT I would do differently the second time around. But I think that's true of life in general. Also, in my head, the wiring portion of this project was to be a negligible expense... 10 trips to pepboys later I spent about $400 bucks this weekend between 35' of battery cable (Sure, move the battery to the back, oh yeah weight distribution, oh yeah) and then drawing everything out on paper (wait i need HOW MANY relays!). You want HOW MUCH for those shitty Chinese fake copper terminals?!!! Also, I budgeted like one day for wiring. Run some wires, what's the big deal? Let's just say I have adjusted my timetables.

    EMI Shielding question

    Interesting, I thought I was trying to avoid interference from the general engine bay. Say, if the wire ran close to the alternator or ignition coils. For what it's worth, I initially fully twisted the whole bundle (and got a massive blister) and then tried to thread the whole twisted set through the shielding, which didn't work. I then shielded just the signal wire and tried to twist the set and the twisting started mangling the wire shielding so I figured I would just let it alone. All my wiring for the various sensors and coils etc are all run separately in there own plastic split loom. ***Followup question that just occurred to me!!! I am running 4 individual LS coils that are fed a 5v square signal. Is it an issue that the coil power and ground wire for each coil are running in the same bundle as the signal and signal ground??? I only shielded the hall sensor since the megamanual told me to... I really didn't consider other potentially vulnerable circuits.

    EMI Shielding question

    So, I can't find EMI shielding that is wrap, only the continuous sheathing. I can get why that is but the sensor is all wired into the harness. It's possible I'm overthinking this. Plan is to start the car next weekend so just wanted to make sure there are no x-factors.
  14. Calling all electrical nerds. For my megasquirt install I am using a Hall sensor and trigger wheel. I bought a roll of 1/4" EMI shielding for the wires but it ended up being an insane PITA even to get it over one 5 foot wire let alone all 3. So I shielded and grounded (to the ecu) JUST THE SIGNAL WIRE, and not the power and ground wire. Could this be an issue? could interference come into the power wire and translate through the signal return or something like that? It is 12V so maybe not a huge deal?

    There are a lot of people on this forum that have lots of knowledge. For what it's worth, I knew ZERO about electronics when I embarked on the project. For a reasonably smart person who isn't afraid to read the technical manual it is very doable.
