Standalone ECU from Scratch

[Halon]

Best of luck with it.

now that good weather has arrived I have made some progress on this setup (that and the fact my stock ECU is giving me problems is speeding up this project)

So I purchased some things that are going to be helpful

one is a zeitronix wideband that will be installed into the car pretty soon I hope. This will be used for the MS. I am keeping the Narrowband in place for the stock computer right now. I am going to be running them parallel for a little bit. I am thinking I might even start the MS system just running fuel and the stock computer running spark for right now just to see how that works out.

The other toys that I have is the fuel injectors FIC 1150. Reason I started this whole project is because I needed more fuel

Here is something I built that I think is really helpful. I didn't want to hack into the stock wiring harness. When I went to U pull I found a 1.8 ECU that the stock clips can plug into. Also in the yard was a 90 laser and I hacked off the plugs off of the wiring harness. Put the two together and you have a wire harness extension!

I thought this would be really useful for tapping all of the lines you need and still not have to tap into the stock lines. In case this doesn't work I wanted to be able to plug into the original harness

Also what is helpful about this is that you are not in the car when splicing into the original harness. I don't have enough room in the car to splice and solder stuff. I can splice and solder connections in my own house before putting it in there. I love this thing!!!! plus now I can label what goes to where. I have tested this and it works. My stock ecu sits on the passenger floor board. Another thing is that if I even have to convert my car to 91 harness, flipping the two wires will be easy!

Can't wait to re-read this thread when I am sober.

You sound like a very smart man, and I hope the best of luck with this system!

Wow, just fucking WOW! Jungy, Im gonna be needing some help when I decide to install my MSII. Im hopefully gonna get that bitch in as soon as I get a new turbo manifold...

Just to keep updated on this project,

I got it to run on the MSII system!

It took a while but now I believe it is going to pay off.

I also got it to run on the 1150cc FIC with no prob on 92 octane fuel! E-85 soon!
Sandalones are great. I mean running on 1150cc would be impossible on a SAFC.

This is so cool!!!!
:haker:

You can run 1600s on a chipped factory ECU...

I love MS. I am running it on my turbo'd 420a with 1660cc injectors and E85. Steap learning curve but once you figure it out it makes you feel you rally accomplished something!

Shit... O well better take my factory ecu and just have it chipped...:rolleyes:

Why take the proven ground when you can re-invent the wheel for much more time and money involved?

Why do you even bother taking the time to post? I know both of your opinions about the system from the first couple of pages... both as expert shop tuners have taken the "proven ground". To me, this is a freaking hobby...

This is how I look at it as posted in previous

Time- yes there is a lot more time and knowledge that has to go into this instead of your plug and play system. It has a steep learning curve to it and there are a lot of things you have to figure out on your own.

Money-
You have to buy or find:

MS2 ECU<-- forgot to add, I had to upgrade to a 4 bar map sensor with altitude correction

$247.00+$65.00

GM IAC, CLT<-- I did splurge and bought new ones... guilty... wanted to make sure they worked...

$17.25 + $16.25

Knocksense <-- uses the factory mitsu knocksensor (or bosh or whichever knock sensor) plus comes with a blinky bulb to show when it is reading knock. can be set for sensitivity. Expensive but better then no knock sensor. I think it is a must for a turbo car

$65.00

WB O2 <-- which I think you should buy even with DSMlink or AEM EMS but that is just my opinion.

315.00

Wire<-- really expensive from radioshack...

um... $20.00 maybe...

Soldering gun <--- however used this to make other proper connections (radioshack again)

$20.00

ECU wiring from another car (Hyundai car worked) + relays

$3 <--expensive....


748.50

make it fair $800 for a ECU+ with WB 02

there you got me...
