Standalone ECU from Scratch

[Halon]

Best of luck with it.

[Andrew7dg]

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...

[Andrew7dg]

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!!!!

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...

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...

No I would say its more of the fact that both of us have seen 1/2 cocked projects and 1/4 built dsm's where owners have decided to try something different where a tired and trued method would have been so much easier for them, and in the end, cheaper.

$800 for an ecu and wb 02 isn't bad, try tracking how many hours you have into this when you are done tuning versus just dropping in a dsmlink and calling it done. I've done similar projects, but perfer to work with projects where there are no other options. SDS systems on turbo porsche 914's, MSII's on turbo probe gt's, hydra nemisis ecu's on pro rally subaru's, haltech e6k's on svt engine swaped rs's, tech 3r's on road race bmw's...stuff that is a bit out there, requires wiring, etc.

I just don't see the point of a MS on a dsm, but thats just me. The project is great and you will learn a lot. Plus, if anyone ever decides to do it again, then can look for you to advise and help if it is well documented.

Yeah, but I blame some of that on the customer and the lack of knowledge that they have. I mean why would they take it to you if they know what they are doing? Why did you have to fix that MS system in the Probe? Really if the owner knew what they were doing they should have been able to fix it themselves. IMO

I am in the landscape construction business. When people want something "different" in their landscape, it usually doesn't work (like you're cocked projects). Maybe by a slim chance but thats if the owner takes care of it. However they never do, landscape dies and becomes shitty and lots of money was spent for nothing. They should have just sticked to hardier plants and tried and true easy care methods in the landscape.
I am sure you saw something like this in your shop and with peoples car projects. Also lots of stories to tell with this.

Unfortunately in this business, we never get the people who knows what they are doing with the impressive projects. (like to point to grass roots magazine $2007 comp with the corvette with the vacuum traction) Why? because the people who know what they are doing can do it themselves for a fraction of the cost and they enjoy doing it themselves. Do you take your cars to a shop? I know I do all of my own landscaping.

There is my landscape and customers rant...

It is true I have put a lot of hours into assembly into this ECU. Would I have been able to drop in a DSMlink and get probably similar, maybe even better results? Much more quickly even?
Yes.
Would have I learned anything?
No. <--- which then I would have probably gotten board with the car project because of the ease of plug and play...

I like to learn, if I don't things become boring really fast and I would have to switch cars. Like lots of you have already done. How many people on here drive DSMs anymore?

I am getting a lot of help from people who have already had success with the system. Plus there is already good documentation on how to get the system working. Like you have pointed out, people who have the system will just rave about it... even if there are better systems out there...
Very fun project!
