Ecotec ECM Program and Harness trimming

[@Wood-Renovations]

I don't know how your videos are not getting views like they deserve!! You're attention to detail and the thought and quality that you put into the build is astounding!

[@DougBugBuilder]

Very kind thing to say, thanks. It's a really small channel and I think a pretty specific audience. As long as those who are watching are taking something away from it then we all win. ;-)

[@TheEZGZ]

Priceless experience and shared info. Thanks

[@tonyweir4]

I wish I would have watched your videos as you were posting them. I literally just completed a ecotec sand rail build and was doing everything as you were, on my own. Lol your experience would have really helped. Except I found someone to program the pcm for $80

[@DougBugBuilder]

Wow! That's a great deal on the reprogram. That must be a rocket in a rail!

[@stevenmark8156]

May we ask who you found to do that for $80 ? That is a super deal! I'm hoping to find a engine and wiring in the near future for my baja bug. Doug has really inspired me in that direction! Thank you both!

Doug, fabulously done videos,so far you are the go to for info I'm learning to do this to my rail, currently running an1800 VW bus engine,bug trans, looking to install an lsj/ super charged ecotech

[@DougBugBuilder]

Hey dude thanks for the kind words. That sounds like that rail will have plenty of power! lol At some point I want to turbo or supercharge my Ecotec. But for starters I just went with NA. Good luck with the build.

[@randellgribben9772]

I am putting in a n/a 2.2 ecotec in my alfa romeo spider..just came across your site here.i was surprised the you took a similar direction on the harness on paper and hardware as i did..i used c.b.m. motorsports to program my ecu..good louck on your build..i am still working on my set up..but going from 115 hp to a bit over 200 hp on a 2300 pound car should be cool.i did a lot of head work and polished the conrods to a mirror finish...

[@somedude0505]

Thats awsome! Im currently working on a sandrail with a 2.3L ford. Not nearly as complicated as your baja since mine is carburated from the 70s. I recently subscribed and im watching all your previous fabricating videos.

[@DougBugBuilder]

Thanks for Subscribing, good to have you on the team. ;-)

[@jorgemadrigal8780]

I love your passion man, can't wait to hear it run.

[@DougBugBuilder]

Thanks! It's getting pretty close to starting her up.

[@DirtGearTv]

Channel is such a great wealth of info!! It appears alpha fab does mostly eco tech ecm programming, any ideas on who might provide a similar flash/programming service for a Mitsubishi? I might just have to get on the lancer forums 😆

[@DougBugBuilder]

Pretty sure Alpha Fab does not do Mitsubishi programming. Most likely need to check the forums for that. Although might look locally first. Then you don't need to send off the ECM. 👍

[@mandfmarine]

What the hell do you for a living? You make me feel dumb! I would be so lost. Super inspiring, learning a lot from your channel.

[@DougBugBuilder]

No way man don't feel dumb! I started my career as a welder and then evolved into HVAC service. So you can see welding and electrical plays right into my professional wheelhouse. Thanks for the comment.

Hi Doug, Outstanding work. I have been following the videos adamantly. I have a E37 PCM 2008 Cobalt L61, for which I am planning to convert into a Mini Stock Oval Track car. Rather than purchasing a new harness, I am wondering about building my own standalone harness using the OEM harness and trimming it down, similar to what you're doing in this video. I am wondering how you determine which connectors and sensors are still required, and if you have the pinouts for an E37 L61 2.2L. Thanks in advance!

[@DougBugBuilder]

Can I assume you have seen the shared folder? drive.google.com/drive/folders/1i0qTcN-1BB5_Lu6umgi9OrvRJKr-0vz3 Check Ecotec pinouts, also check the Harness connectors. That shows basically what connectors you'll need. Minus the VVT plugs. Now differences between the E67 and E37 I'm not sure of. Only way to know that is to get your specific pinouts. Did you see the video where I show how to get the 3 day subscription from GM for your pinouts? If not let me know and I'll link the video for you.

[@BoyesFamilyMotorsports]

@@DougBugBuilder Hi Doug, I have since logged in and read through your entire folder. I have also removed the harness and labelled each connector. I am now ready to start. I think my main confusion is understanding which circuits turn the ECM "on", and where battery power, ground, and ignition control needs to be run. I have read the schematics and see the main control from the ignition switch seems to travel to the BCM, before I'm assuming sending 12V to the ACC VOL connector on ECM Connector 1. I am then assuming this powers on the ECM. I also see which pin sends "Starter Control" voltage out to the starter and/or starter relay, but I'm unsure which pin into the ECM actually tells the ECM we want to begin cranking. Thanks for any help Doug.

[@IllusoryRedoubt]

Awesome Doug, you will be ripping the trails again soon 👍🏻

[@DougBugBuilder]

Hopefully yes! Very excited to see how this motor feels on the dirt.

[@MrKingofcomfort]

Thanks for the information

[@DougBugBuilder]

My pleasure, thanks for the comment.

[@vicferrarisgarage]

In you wiring, did you find a tach signal wire or pin for the older neg coil type tachs?

[@DougBugBuilder]

No I didn't. And I looked, I was never able to find anything to hook up a tach to. The only thing I have for a tach is the digital dash setup I have. Which basically displays info from the OBD port.

[@timvandermeulen7265]

Excited to see how it goes! I am assuming you will be eliminating some wires from the original harness with the programming changes to the computer. Great Video as usual!

[@DougBugBuilder]

I'm working on removing the wires right now. I'll do a recap of that in the video when I start it up. Thanks for the comment bud!

[@8.2deck]

What ecm do you have?

[@zoompixelofficial]

salam saya senang menonton vidio di chanel anda dengan membahas soal mesin 2,4 ini dan kebetulan tahun lalu saya baru saja memiliki mobil bermesin yang sama. saya tertarik dengan buku yang anda miliki bolehkan saya mendapatkannya karna ditempat saya tidak semua bengkel paham dengan mesin ini.

[@dalejrfan820002000]

How do you know what to use and what not to use?

[@DougBugBuilder]

You need the pinout diagram for the ECU you are running. This will tell you the sensors it's using and where the wires are landed. Then you can remove the wires you don't.

[@dalejrfan820002000]

@@DougBugBuilder Ok I appreciate the information . Thank you so much.

[@jaimelopez3598]

I have a 2.2 ecotec engine that i would like to put in my dune buggy. Can you tell me if i will have any kind of issues with putting it in?

[@DougBugBuilder]

Hard to say exactly but the Ecotec doesn't take much more room than the air cooled motor. It's a couple inches longer, so depending on your cage setup you might need to extend it a little.

[@jaimelopez3598]

Ok thank you ! Is there advice you can give me for the wire harnes installation?

[@DougBugBuilder]

@@jaimelopez3598 If you are really handy with wiring you can do it the way I did. Download the wiring diagram and modify a factory harness with what you need. Then you still need to send your computer to Alpha Fab and have them flash it for you. That'll cost about $350. Or Alpha Fab sells a complete wire harness kit with relays and a computer for $750. With that you just install the harness and you're good to go.

[@gordonellisjr331]

I have just started doing my own internet research and pouring over wiring diagrams, connector pinouts ect. for my project. I just came across this youtube video. I am building a 2005 Cobalt 2.2L & 5spd manual into a dirt track racer to race in the mini stock class. What was your donor vehicle? (year, make, model) Your ecm is completely different than what I have. I really hope mine can be reprogrammed for standalone. Not sure what to do if it can't programmed? Do you know of a web sight that has a list of ecm's that can be programmed standalone? The service # on my ecm is 12589998. I really appreciate the info and effort you put into making these videos. I have subscribed to your channel and will definitely check out your other videos.

[@DougBugBuilder]

Gordon, My ECM and engine is from a 2007 Cobalt. My ECM is the E67. Yours is the older version (not sure what it is called). I'm very confident it can be programmed for stand alone. Alpha Fab did mine and it's working great. I'm sure they will be able to tell you what can be done to yours. This video from my Ecotec series has very valuable info on a website that will get you 3 days of access to GM wiring diagrams for $20. That's where I got most of my info. kzbin.info/www/bejne/fanRaYKrqM9nZpY I hope the videos help, don't hesitate to ask me any questions. Good luck with your build.
