Ecotrons is looking for someone to do the 1st DR fuel injection kit - $250

14 posts in this topic

Matt from Ecotrons is looking for someone to do the 1st DR fuel injection kit install and he's offering 1/2 off so it's $250 to have FI on your DR. Read this thread:

It's not feasible for me to do this (being in MX) so i'm passing this along.

Jeff from Procycle , MXRob, others ???

you must have an A game as far as working on bikes and with computers.

OK, I'll call shotgun if Jake cant hook up.... :smashpc:

matt is looking for 2 people.

another guy was in too dropped out.

I have worked in the automotive field since I was 10. I have rebuilt carbs trannys and engines as well as diesel injector pumps and converted several jeeps to fuel injection.

Next in line!!!

I am in Australia. Been reading the website for the FI. Seems simple enough to do in that PNP kit form. Is same price as goimg to a TM40. Will be making a final decision very soon.

guys I e-mailed Matt this morning to bow out. I told him to pick whoever he wanted. I simply don't have the time for a project like this. My bike is my DD and I can't afford for it to be down for any extended amounts of time. This looks like a doable project though, and hopefully soon we will have an affordable PNP EFI kit!

Jake alerted me to this FI prospect. :thumbsup: Looks quite promising for a PNP system. I've been in contact with Matt @ Ecotrons over the last few days. There are a lot of issues to work through with fitment of their 42mm throttle body in the space available on the DR650. The base length of their 42mm TB is 125mm... we have 98mm to work with... give or take a bit. I've sent him pictures and dimensions of the Suzuki TB's I modified for my FI project. He also needed a bunch of other info concerning the degree placement of the stock VR lugs on the DR650's rotor and coil input info... I've committed myself to supplying him any info necessary to make a DR650 PNP FI kit a reality.

I've been studying their web site.... these guys have a lot going and are committed to building an affordable FI system that has no technology short cuts. They are using all of the latest FI technology in their ECU. It's a tiny thing compared to to the MicroSquirt unit I put under my seat. :smashpc: They have addressed the sequential mode operation using MAP. Speaking of MAP they have assured me they can provide a system that can work even on the DR650's radical MAP signal. That would be fantastic and what is required to get the best fuel economy.

Their system will be designed to use the stock VR and rotor lugs but I told him about the major improvement my machine showed in low speed running having a 36 tooth wheel for the sensor to read. They are fully capable of providing the firmware upgrade to read the 36 tooth wheel. A toothed ring would need to be installed on the DR's rotor in place to the two stock lugs. It was my plan to do this on my system anyway to eliminate the need for my hall sensor and utilize the stock VR. It would be a lot easier to remove the two lugs and press on a 36/2 water jet cut ring on the rotor than what I went through machining the teeth in the flywheel weight on the back of the rotor.

I've also communicated to them that the system has to be very reliable and spare parts can't break the riders bank account if they are ever required. Spares "on hand" was another point I told them was important.... riders can't be waiting for months for parts to arrive. Matt assured me all of these items are in their capability to provide.

I received a reply from Matt a few days ago that he accepted me as a second. I have lots of spare time to devote to this and a fair amount of experience. Eight years as a motorcycle mechanic, twenty years in moto racing, and about the same as a computer specialist.

My DR has a hot cam and titanium exhaust among other things so it should be interesting to see how it turns out.

mx_rob,

did you use an O2 sensor or sensors for your project ? If so where did you mount it ?

I'm not thrilled to mount one anywhere near the front where it's so exposed. If I go in the dirt I don't think it will last long. Matt prefers his O2 to be mounted 3-5" from the flange.

Go to my web site. Click on the DR650 Mods button then the DR650 FI Link. Lots of info there on my project. The msruns link is a digest.... the TT link is War & Peace. :busted:

But in quick answer I chose your "preferred location" for the wide band 02 sensor as well so it wasn't hanging out in harms way...... and looking stupid. I did have to deal with sensor latency though for which the Microsquirt and Innovate's LC -1 wide band controller had a work around. We'll have to see if that is going to be the case with Ecotrons firm/software. For SD control it would be best to eliminate as much latency in the system as possible. I'm certainly game to move it closer if necessary. Glad to see another DR650 FI guy on board. :smashpc: Ecotrons has certainly made the likelihood of others jumping on the bandwagon a far more likely occurrence. :thumbsup:

I mounted mine in the same place, as suggested by mx_rob. Just be careful not to weld the bung too close to the cylinder. If you do, you won't have enough clearance to put the head pipe back on :smashpc: I was lucky :thumbsup:

Well after talking to Matt, he seems pretty convinced that for his system it needs to be 3-5" from the header flange.

Reasons 1 - The O2 sensor would not be as accurate for combustion AFR

Reason 2 - The O2 sensor would take longer to heat up therfore longer to obtain Closed Loop Control.

Reason 3 - To get the O2 sensor to peak operating temp, the ECU heater would run continuously with a current draw of up to 1 amp.

Anyway, I'm going to try to set it up without an O2 sensor to start with and see if I can analyze the mixture the old fashioned way. :smashpc:

I am currently fuel injecting a dr350 and the total cost came in just at 500. Got good deals on the throttle body, pump, computer too. If he can plug and play for that price he is doing a good service for the DR community.

There is not much room to position the O2 sensor where it doesn't hit the engine or throttle body like msiddalingaiah said. I bet with the bigger 650 engine the margin is even less.
