MAF delete
So, I picked up a used MS2E rev built, and I just have a quick question regarding the MAF... I'm being told by some friends on another car forum that if I want to VTA with my BOV that I'll need to pick up a MAP in order to ditch the MAF.
I understand the issues with a MAF and VTA with running rich and whatnot, but it was my impression that this was a non issue with a MS. My MS2E has a little boost line connector on it, does this essentially replace the MAP? Also, I see that DIYAutoTune et all sell a GM IAT sensor, should I worry about upgrading to that? Or is my stock one okay? Is it PnP, or do I need a different bung welded? And I assume I'll need to re-wire the harness? Sorry, I know these are noobie questions.. |
Heres what you do. By an IAT sensor and run your MS and be done with it. Run the IAT right after the Intercooler cold side. VTA the BOV all day and win. That "Boost Connector" you see is for your MAP line.

And this is the sensor I want, right? GM Open Element IAT Sensor with Connector DIYAutoTune.com Isn't it just plug and play in the stock IAT spot, or do I need a new bung welded? |
are you seriously trying to set a record for the most amount of stupid questions asked in the shortest amount of time?
I swear I'm gonna pay Scott to ban you. I mean how do you plan to tune your car when you don't even know literally the most basic things in the universe concerning MS? And I PROMISE you I'm not saying this to be mean or flame you or haze you. I'm genuinely stunned |
Please just pay someone to set your MS up and tune it for you. Otherwise DONT TOUCH ANYTHING on your car or on the unit you bought until you at the very least know what a megasquirt is and what a car is and how the two relate to one another

Right, so I don't need an additional MAP sensor, I just run a vacuum line to the MS, correct?

Sorry I'm so annoying to you, but if you'd read my post again I'm basically saying "hey guys, I've been doing quite a bit of research, but some of my friends are telling me that I'm wrong. I believe my MS boost line replaces a MAP, and that I can put this GM IAT in place of my stock one, is that all true?"
Yes, i've read through megamanual, yes I've read through the directions Rev sent me, and yes, I've searched and I've browsed the stickies, and no, none of those places provide me with a direct answer to these questions. |
And yes, I read the stickied "MSPnP FAQ" and many of the "Super important megasquirt threads" and still haven't found the answer.
Before you get all huffy and give "negative props", find me a clear-cut answer that's somewhere that a *noob* would know to look, or a search string that finds the right answer--not one that you know of because you were here 4 years ago when it was discussed in that one thread that's now on page 9. Also, I do have a mate who has agreed to show me the ropes when it comes to megasquirt and tuning. I'm just trying to get all my parts together. |
I'm not annoyed with you, and I'm not negative propping you.
I'm genuinely concerned for your car, because the amount of knowledge you're displaying is literally next to none, and I genuinely don't think you should even go near the car or the MS you bought until you actually know at least the bare essentials. And I 100% beyond a shadow of a doubt don't believe your claims of "I've read it all, still don't understand"........There's so much detailed info even my dog can learn to do it. Unless of course you're less intelligent than my dog...... ......anyways, to answer your questions: -the "boost line" you're referring to IS a map sensor built into your ms -yes a gm iat replaces your stock one and you need to weld a bung in for it I suggest you go on the DIYautotune site and msextra and start by reading "WHAT IS A MEGASQUIRT", then "HOW DOES IT WORK", then "SETTING UP MEGASQUIRT IN A MIATA".....basically the 2+2 basic knowledge that is so entry level, most of the threads on here assume you wouldn't need to even waste your time reading them |

Do your friends have turbocharged/megasquirted miata's? No? Then stop listening to them.
Good luck. And I really mean that. |

Forget your friends man. Never second guess a huge community of miata turbo owners majority of which are running a MS.

Also your friends and you are saying the same thing, except they don't know that your ms has a map sensor, and you don't know either.
The fact that you called it a "boost line" tells us everything that we (unfortunately) need to know about your level of knowledge. So here's what you do (to fix this problem): Read up on MSextra and DIYautotune on the basics. Then read the threads here. Then read rev's "manual" on hooking up the ms (if he didn't give you one I think there is one Scott posted somewhere here too, if not I'll post one). Just those things alone will get you to the level of knowledge where you'll be asking intelligent questions and we can actually help you out |

If all of us were so insecure that we made a thread each time one of our idiot friends told us something vague or misleading, this forum would be in the billions of threads by now. Sack up and do some research. I'll give you a +prop just to make you stop crying :) |

all of them that run speed density (basically all that delete the maf) run a map sensor and ait sensor. setting up an ms2e and ms3 basic should be almost exactly the same

Also, to be clear, this is the thread that really threw me off when it came to the IAT.
https://www.miataturbo.net/megasquir...ow-what-76953/ From Post 5 in that thread, which is a quote from instructions from rev on the MS3 "7. If you want to use a GM IAT sensor, it must now be wired in. • On the 99-05 (Non-MSM), simply replace the stock air temperature sensor found " "If it's like my 2000 model, it's pretty simple. Run a vacuum line off of a T at one of your existing lines. Install and wire-up your WB. Unplug and remove the factory ECU, and plug in the MS3 and zip tie it up under the dash. You should be able to use your factory IAT sensor, but if you want to place it with the GM part that's a superior sensor. Start the car and begin tuning/tweaking with tunerstudio." |

Sorry, vacuum line then. As I mentioned earlier, I've read the instructions he sent me, and they didn't mention the IAT at all. I found a similar list of instructions which DID mention the IAT, but those were for an MS3 Basic, which I don't have, and I assume following instructions for a megasquirt that's not the same as mine is a quick way to blow stuff up.
I will continue to dig through the forums at DIY and MSextra, and I also discovered that there are some decent tips in the "making and installing your own MSPNP" thread which I originally overlooked as I thought it was strictly for the soldering/construction of the MS board, which I'm not doing. |
trust me, you don't wanna use the stock ait sensor unless you are n/a.
to get any sort of proper reading, it must be in the pressurized piping not the inlet that's on nb's on na's to retain the stocker you have to retain the stupid maf. so that's even more fail. so pretty much everyone uses the gm iat |
so I need this one: MSPNP and DIYPNP IAT Sensor Kit - Aluminum Bung DIYAutoTune.com which comes with an aluminum bung, and then I need to find someone who does aluminum welding to weld that into one of my charge pipes downstream of my IC.
|
yup.
or you can drill/tap the coldside end tank and screw it in there requiring no alum welding |
You all rock. Becomming a site supporter is on my "parts list". There's no way I could do this without mt.n
|
Technically yes, but it's much easier to drill and tap the thick aluminum on the cold side of your intercooler. That's what many of us do, and requires no aluminum welding and you can save a few bucks and get the no-bung included AIT sensor.
Edit: too slow... |

Edit: too slow... Its a win win win. 1 win for no welding, 1 win for no heat soaking and 1 win for being resourceful and not spending extra monies. |
