Default MoTec M4 ECU / MoTec engine harness product review

Well I have been playing around a bit with this new MoTec M4 and engine harness.

The reason for this post is to illustrate the quality of the work. There is nothing on the market today that can compare to what I have in front of me. If you are in the market for a new standalone ECU and are concidering anything from AEM EMS, Haltech, Accel DFI, FAST XFI, ect.... this is your answer. MoTec carries the name of being expensive too, but in all reality it's not that much more than the AEM EMS. I won't lay down what was paid, but it was only a few hundred more than the AEM box. The harness, which was not cheap, was made by MoTec as well. You can get the Honda harness from MoTec or you can use their "DIY" type harness that you can make yourseslf. If you want to save almost 1k, then I would suggest you do it yourself. In my opinion it was money well spent.... look at the pics and see for yourself. The quality of the hardware is second to none.

For what it's worth this harness will be the last harness.... ever. My reason for this setup was because of problems that I had on the dyno. The engine harness that I made, was custom, but copied what Honda had designed. I mimic'd 100% of shielding, wire gauge, ect.... and still had problems. I quickly got tired of what "could" have caused my motor failure and this was the end result.

The company that sold the MoTec and provides great customer support was none other than T1 Racedevelopment. Tony had modified the harness to accept his T1 cam trigger setup, to accept the M&W Pro 12 and to accept my AEM 5-bar MAP sensor. All work done by himself was perfect as well. Everything is "plug and play". I had talked to Tony about what I wanted and he made it happen. Too easy. Just gave him my debit card number.... lol

Before the pics I just wanted to say thanks to Tony for the support that he has provided with this product. I had spent many, many DAYS speaking with him via PM and phone calls. All my questions were answered and if he didn't know the answer then he researched it and got back to me.
That's customer service.

Alright, here are some pics that most don't get to see.

Enjoy....

LOL.

Go figure.... I laughed when I saw that my first time too.... I don't know if that was MoTec that did it that way or if it was Tony being a wise ***.

Either way that relay may be used for something else.

I recently used MoTec's flying lead harness and added all the provisions I wanted for my application and it turned out great. The quality is top notch. MoTeC and raychem FTMFW.

Ya, it looks nice, but what is the actual difference between the harness you made and this $1k one. Is the wire different guage, different clips, the fact that the wires are all covered/labled? It looks like the wires are held together by twisy ties in the 3rd picture.

It is guarenteed to work right the first time. lol

The wire strapping is what I use in the military on ARMY helicopters. It is a wax coated nylon string that is used to tie wire together. Doesn't dry rot or breakdown in the elements.

The difference in the DIY version and this is that it's assembled. The DIY loom is just a mess of wires, no wire covering/lebeling and is time consuming.

BTW I fixed the lableing issues. Now it's right and it matches the yellow on the rest of the harness....

OCD FTW!!!

Good stuff man! I would have gone the same route you did! I just keep hearing more and more great stuff about moteC! Great quality stuff. Nice to see the T1 trigger wired in as well!

That's pretty cool. I noticed you're running the Pr0-12 so I'm guessing you're going w/ a wasted spark coil on plug setup?? Good luck w/ you're new setup. Seems like you'll have a true condendor next season.

Great quality bro

But I have seen a few post lately where people have stated the cost is not much more than the AEM. Well I have to disagree with that because there are a lot more AEM EMS running around than the M4. Getting a cheap AEM EMS is easy these days. I have never paid more than 700 bucks for a box. If the M4 was more popular than I can see that. It's a great system, but still more expensive. You get the T1 trigger, and it is still quite less. Were talking both used and street price. None the less, you have a great system right there, but affordable is still not in the same category.

come on now.......

you cant compare the "street" price of used boxes.


thats like comparing the used value of a ford escort and a honda civic. the honda civic is a better car, so it holds its resell value much better.

if you notice most of the "high end" products in this industry dont sell for much less used than they do new.


stuff looks real good

Why not, that's just pure fact. Any one of us can get a box for that cheap, and that is a viable option as well because the fact there are more boxes out there in our industry. If the motec was more popular then I can see that as a comparison. But the fact that there are more AEM EMS out there, does make it cheaper. Because the consumer has more options to him. The motec m4 is still something that is very out of reach for many people, the AEM EMS can be had much easier and CHEAPER because of its popularity. That's all I am saying. Also the Motec seems to stay at a certain height in price. You don't see many lowball prices on the Motec system, where anyone can go to ebay and get a AEM EMS for a super great deal new. It's just the reality of things, not taking anything away from Motec.

Dude Motec is a better system FLAT OUT! Why is the person getting rid of their old aem unit? Probably because the upgraded, moTec/Haltec and others.

Alright.... how about this....

Have you had any problms with your AEM EMS? If not you soon will. lol
I have friends, and many of them are H-T users, that have had nothing but problems with the AEM box. I don't want that. I would rather spend a few hundred more so that I don't have to ship it out to get it fixed. That's just BS and is not tolerated in my book.

I agree though the AEM EMS is the best bang for the buck tuning solution, but when it comes to quality and being trustworthy that's where the MoTec shines.... Hands down, no arguement.

PS: and I was comparing a new AEM unit to a new MoTec M4

I guess I am just the lucky few LOL. Cause I have only had to send my box in 1 time, and that was years ago. And I have had it from the very very beginning. I bought it used with a bad coil driver. It's the other stuff they make I have problems with. But the AEM EMS, no problems for me, and I have tuned quite a few of them with no issues. I don't know why people selling them, that's not the point. I have had more problem with there wideband than anyting LOL. No one knows why, but I know how to use it, and I am confident with it. Maybe someday down the road I will upgrade to the T1 Trigger, but I have yet to need to like some people on here. I am sure my time will come, if what you say is true. But it hasn't yet.

I understand your comparison, and I have nothing bad to say about the Motec. But the way you make it sound, it's like only a few hundered bucks more when in all reality it isn't LOL.

That's what you're not understanding. A new M4 is only a few hundred more than a new AEM EMS. Not everyone needs the baller harness. And who buys used crap anyway? lol

I do understand, I have researched this very thing myself. Who buys used crap, well everyone, probably including you. This is the honda scene, everyone does LOL. Glad you got the M4. It's THE SYSTEM, the baller system, and that what it is baller $$ period. Trust me I know, I live 10 minutes away from RRev. John Reed is not only a great tuner, but also both a motec dealer, and a AEM EMS master. Maybe I have been blessed with good people around me, and people on this board that are helpful that you don't see me throwing my AEM EMS out the door or on the classifieds. I'm jealous, but u are right, it is the most cost effective system out there WHEN IT WORKS. The Motec is still $$ no matter how many times we talk about it.

Wowza, that's some hot **** right there.

One of these days I will get rid of this Dseries and end up with two cams and a MoTec.
