I'm looking for ANY AND ALL links to .msq files, wiring info, work arounds, anything usefull....
Also looking for someone with experience to help make a fairly well laid out guide to setting up a MS3 on the renesis, please and thx!!! ^_^

(ONLY LOOKING FOR REPLIES THAT WILL HELP WITH THE PROGRESS OF THIS PROJECT, NO CRITICISM OR RANDOM COMMENTS *unless it's praise :P*)

Will be starting this project in mid to late November and I'm trying to build my knowledge on this AS MUCH as possible before hand.

cars stock, except I`m looking at a ignition coil amplifier (2 stage) for stronger sparks and my cat is hollow if that makes any different, I`m mainly doing this because I know I will be switching my engine for the 16x when it`s released and I want to start preparing by ditching the stock ecu and learning how these systems work before I go and drop a brand new engine in it...

Are you planning on using the stock trigger wheel...or going with a different trigger wheel?

Brandonien

iTrader: (2)

the trigger wheel is 36-2-2-2 to my understanding (*rotarygod had a thread on this*) however in MS3 36-2-2-2 is an option now so I should be able to use the stock trigger wheel

the problem I keep coming accross is the throttle body since MS3 doesn't support drive by wire I need to find a suitable replacement for that..

You can buy a throttle body from a pro formula Mazda car, star race cars I believe. Then a second gen rx7 pedal with cable, fits very nicely. You need to fab a bracket for the cable, I had mine done for me and it looks oem. The throttle body comes with the tps.

That site is amazing! Thx, I wish I'd known about it MUCH earlier!

How are you planning to control the APV function?

Why didn't you buy an ECU that supports direct injection then?

Brandonien

iTrader: (2)

O.o I'm fairly sure megasquirt 3 does support direct injection and I haven't bought it yet! :P which is why I posted this thread, to find out all of the things I may need to work around ^_^

bse50

In the end they're still injectors so you're right
I was just pointing out that getting an ecu before even knowing the future engine's specs may be overkill! The new megasquirt looks like a fun tool though, swap or not if all you want to do is having fun programming it then why not?
Isn't it better to get an accessport though and download the free tuning application to get started? MazdaManiac's web seminars are a good specific starting point too!

This exercise in pointless foolishness might be better appreciated on the MS3 forum ....

Brandonien

iTrader: (2)

I'm actually ordering the accessport right now, and the MS3 will be piggybacking the stock ecu since it won't try to change the maps after the AP gets at it! :P later in the year I'm switching my fuel lines, pump, and injectors and adding a flex fuel alcohol sensor, so the MS3 will take over when it detects anything other then normal fuel ^_^ this engine is like my test bed for tuning before the 16x gets released (*because I'm DEFINATELY swapping engines when that comes out >: ] *) PS. decided to keep the stock ecu in as well, my initial concern was not being able to piggyback it and then I was told to research the AP

Please keep posting here! I find it interesting but I don't want to join a million forums. I am now subscribed to this thread and I would love to here what you need to do, and what challenges you face while exploring the application of the ms3 on the rx8.

PS: if you start a thread elsewhere specific to the ms3 (and the rx8) please share it here. Thanks!

Why be fixated on an MS3 when it's not the right choice from the start?

Even if we ignore the 16x BS and "I'll buy one some day" dreamer fantasies the fact that you've chosen an efi system without doing the basic research first is an automatic fail.

sblethen

iTrader: (3)

What are you using?
What have you tested?
What are your dyno results?

I am keeping my stock engine based on the ruleset of the class I am racing in. ECU and everything that goes with it for sensors (other than injectors and throttle body) is "free" to change per the rules as written. Most people that race are using the megasquirt system or the motec. I am open to both and megasquirt "if it will work) is significantly cheaper. If it yeilds 5hp and better tourque its probably investmentfew thousand $$ investment. (For me anyway) the motec is about 10k!

Well at the moment I'm in Afghanistan, So if your going to tell me the money I'm putting aside EVERY paycheck for that engine is BS then please don't post on this thread, cause I don't feel like having someone tell me that the work I do in the INFANTRY doesn't pay well enough to fund my ideas. And really... IS PLANNING AHEAD A BAD THING, this thread is for MY RESEARCH, if I deem it's not worth my time I'll stop but as of yet theres nothing to prove it's not a worthwhile project..

Brandonien

iTrader: (2)

sorry to be rash but I don't much appreciate you telling me my ideas are childish or bs

also I haven't bought this system as of yet, so yeah I should have researched other systems, however I have a friend who uses MS2 on his fi neon and has shown me the basics of the program and some of the features its capable of, so considering I don't want to spend 10K on an ems unless I have too and the low cost of this system even if it turns out to be a failed project I will be down less then 1K so I'm not too concerned

Brandonien

iTrader: (2)

all in all it will be an interesting experiment
and I'm not going forced induction right now because I would rather save that money for the new engine, and all the fun times that will be had trying to get that to work in an 8... (*haha*) I guess you could say the 13b is my learning platform for tuning so I have a base when I do start dropping money on the bigger things

Brandonien

iTrader: (2)

you say I'll buy one someday fantasies, gee maybe the reason I HAVEN'T is because it's not out yet! (*light bulb appears above head*) how arrogant can you be!

sblethen

iTrader: (3)

I assume your talking about teamrx8 and not me. I honestly am interested in your findings. I race against several people using the megasquirt system but I know nothing about it and I was thinking the motec was my only option. I am starting to read up on this type of stuff.

And don't let post addicts get to you... I ignore them. In reality a post addict can't help it (honestly) and will post something rather than just move on to something they are more interested in.

good point, ^_^ unfortunately this will be a slow moving project as I'm about to get my hands on an accessport and plan to find it's limitations before I start wih the MS, however as winter comes to an end this year you'll start to see some actual progress :P figure I'll take the winter and plan my attack of wiring and make sure I have everything I need

Salamanth

Bradonien, what team is saying does have some merit.

You seem to be jumping into this half-cocked without doing much research... for example, ignition amplifiers are nigh-on worthless on our cars, and in fact, cause more problems than they solve.

A hollowed out cat most certainly does make a difference as well.

These are basic facts anyone should know before starting on a project of this magnitude.

My personal advice would be to buy an FC (they can be had rather cheaply these days) and swap that over to a megasquirt if you want something to play with. It is not a project I would want to undertake on an RX-8.

This advice is coming from someone who is currently 'squirting a turbo 2 swap done into an FC vert.

However, if you choose to continue down this path, though I and others think it's foolish, there is a wealth of information to be had on the rx7club forums in the megasquirt ECU section. In addition there is a lot of info over on aaroncake concerning the MS2.

http://aaroncake.net/RX-7/megasquirt/index.asp

There are many things to consider:
- How will you handle the piggybacking of the stock ECU and the MS3(X)
- How are you going to deal with the fact that the stock renesis has 6 injectors that it stages and the MS3X only supports primaries and secondaries in staged mode
- How are you going to control the APVs
- How are you going to control the oil metering pump

I have answers to some of these questions, however (as ******* as this may sound) I want to know what your thoughts are, if you've even considered these.

I would encourage you to stay on this path, just be aware of the challenges you are likely to face and know the limitations of your knowledge if you're determined to continue.

Ahhhhhh, the sweet sound of reason .....

Brandonien

iTrader: (2)

Hey SWEET! Someone finally presents some encouragement :P Anywho Yes:
-I will be using a wiring harness as per RG's thread for all my splicing to make a clean and convenient setup that allows room for error..
-primaries on one stage, and the remaining four on the second stage, it's been done and works
-well I was thinking of mixing oil in with my gas initially although I would like to use a mechanical OMP once I research it a little more...
-throttle body issue is sorted out as I plan on using a gm tps and tucking my stock tb away somewhere
-and since both secondary and auxiliary injectors will be going at the same time, so will the apv


I know this is going to be a steep learning curve but I've got nothing but time for it, I also figured I would play with the 13b-msp before I go and F*** up a brand new 16x engine... only problem I can see with switching from one to the other on the MS3 setup will be the trigger wheel and the injector and spark timing since it will be a DFI engine... but I guess that means I'll just have to wait out till then... Still getting it regardless since I can use e85 with MS :P
