Here are the links to the "instructions" The Hoedar for my Zuma just shipped today. I will hook up to the one on my Z125 and play around and see if I can learn anything. I will post up some screenshots of the map and anything else that looks useful

 

Problem is, no instructions, no info, no link to software, no anything, just an ecu in a box. There is 100 times more info on a $4 bag of tater tots.

I thought you were just kidding :grin2:

 

ya .......... i goggle everything :nerd:
.
so I had to see what whats involved with all Mapping ?
.
download link is legit .
.
first folder (pic 2) lists Z125 and Zuma , so ?

 

I had to create a new account to get back in here, the one i created yesterday would not let me in no matter what i tried.
Thanks for the help, i was able to find the downloads with the link you posted. Unfortunately the translation makes most of it impossible to understand or comprehend.
It's just a $530 bad joke. Looks like i will be leaving the bike bone stock, which is a bummer because it won't climb the 50 mph hills around here at anything over 40 mph, and i have a ssp-g 138cc kit, Hindle pipe, Otb intake and kitaco cam in the garage that will all have to go back.
Fuel injection is really making ownership a disappointment.

 

"nor am i interested in having someone else set it up for me. Apparently everyone with a hoedar is at the mercy of having to contact this guy and "link up" to be able to use it? Completely ridiculous. I don't do facebook, have no idea what "whats app" is, and do not have a cell phone..."

Well, I have a Hoedar ECU on my track bike and it works great, but due to the complexity of such an open architecture ECU the initial software setup is daunting for a first time user. Thankfully the US distributor is a wiz at setting it up remotely over teh internet and he had my engine running smoothly in no time. The Hoedar ECU is not for everybody as it requires some knowledge about EFI tuning and it's infinite tuning options means it's easy to get it wrong. Sounds like you should have done more research before buying it. Several other forum members on here are running them successfully.

I also have used a Dynojet PCV and Bazzaz ZFi in the past and they work well so I'm not sure why you have such an aversion to them. They are used by the majority of bike owners and their wiring is pretty easy for the average DIY owner to install and they are up and running in an afternoon. There are plenty of Z125 maps available for both to get your particular engine combo running in no time.

Maybe you can find a local tuning shop/mechanic to help you install it and your engine parts on your bike? Otherwise you might be right to just keep it stock. Good luck.

 

saw your post in engines , but leaving that to the experts here.

but Re-Gearing to -1/+2 could also really help for those hills

I only have an aversion to scotch locks and posi taps. If i go the pcv or bazzaz route i will buy another factory wiring harness and rebuild it to incorporate the controller within the harness.

I have scratch built over 15 motorcycles in my life, mostly top fuel drag bikes, but several street bikes as well. I can install the parts and ecu fine, i can tune fine. The problem is, if this guy suddenly becomes unavailable tomorrow, i (we) would be s.o.l. with out the info readily available.

That said, he did contact me today and has agreed to hook me up with the info so i can handle the setup myself. Turns out, according to him, 99% of people don't care how to use it and would rather have somebody else do it. That baffles me to no end.

So, we will see how it goes from here.

 

So if you don't like posi-taps or scotch locks, just straight wire it in. It's literally one wire. I have my PCV with autotune module wired straight into my tps wire very carefully so if it needed to be taken off, it could be covered and sealed back with the other wires cleanly. Had connection problems with the posi-tap, did this and haven't had an issue since. If you need instant access to info this is probably your only choice if you don't want to watch Chris at Hoedar do his thing setting you up, and then going from there. I'd say if you set up those types of bikes in the past though and have done efi tuning, you can get over this learning curve no problem.

 

Larger tires and the Hoedar are the 2 top items I've done so far.

 

Did you Receive enough info to set it up and use it yourself?
That's all i am wanting, don't want to be dependent on knowledge that is only stored in someone else's head. Hoping they will get back to me soon.

 

I'm looking at picking up a Hoedar as soon as I get my ECU recall done. I agree with the OP and would prefer that I had all the info I need to change things to my liking. I don't mind having someone do an initial set up, but I don't want to be dependent on someone else to update settings if I go BBK... mostly because I have to 'borrow' a laptop to do so. I've downloaded and archived the software and Z125 map from the link above, but if @dodge has a manual/tips/help guide, I would appreciate a copy.

 

Well, after multiple emails with Chris at RC scooters it is pretty clear he is not interested in putting anything in writing. I even offered fifty dollars for 30 minutes worth of beginner notes and he did not even respond to that part of the email. Bummer but I am sending it back. The only way to get info is to set something up to get him on the phone. I guess this would be ok if you were planning to set it up once and leave it, but I like to play and Would like some written reference material on the system, I can screw with the tune to my detriment or amazement, would not expect info on that part, just on system use. I told him I would pay a hundred dollars more for a new one if he ever develops a manual.

I am looking at the sp takegawa controller which is 100% direct plug in. Unfortunately the description is translated and it looks like it may not drive the factory tach? Does anybody have any first hand experience with that one?

 

Will Chris take the Hoedar back? I would think you would lose less if you sold it vs paying for return shipping...

 

He sent me a return shipping label and has promised a full refund. I really did appreciate that.

 

I don’t like how Chris makes multiple claims about how much power a hoedor ecu makes or how good his tune is without data to back it up

 

My take is that if you are going to spend big bucks on Bazzaz or other piggy-back style fuel modifiers, you might as well spend a tad more and go the Hoedar route. You can really dial your fuel map in with this thing. Got mine to the point where its running in open loop thru out the rpm/tps range. Starts great...never dies as it once did..pulls strong with afrs around 13:1 at WOT and is set up to run between 14.7:1 and 15.0:1 in the cruise cells of the map. Got 125mpg on my last tank of fuel. I'd get one for the Buells and VFR if they were available.

 

My Hoder is having a cold start issue... Too rich, have to crack throttle to start. Any idea how to change cold start ratio? I'm sure Chris would help, he's been great in the past, but don't want to bug him for every little issue! Also, should this ECU's not be learning? Saw someplace the auto tune settings are from 1-100 quicker to longer.... what is everybody setting them at?

 

Exactly why i sent it back, Should have at least a basic reference manual so everyone is not at the mercy of trying to contact him.
I don't get it, In the amount of time he spends with just a few customers, he could do a few basic reference sheets.

 

Someone should start a Wiki page....

 

@dodge, can you post that publicly for others' future reference? Seems like everyone is hush hush about the Hoedar configurations. Makes me think that nobody really knows what is going on...

 

No hush-hush here...be glad to share my ecu file to anybody who has a Hoedar. 143 cc, aftermarket ex and intake. Runs like a champ.

 

I have to wonder, why produce something that is supposed to have the advantages of being infinitely adjustable..... then withhold any information on how to use it to make adjustments. It's like a delicious looking plastic cake, looks yummy but you can't taste it.

 

I have a hoedar installed on my z125 and have one on order for my Zuma 125. Its got a 192cc big bore and needs all the love that the hoedar has to offer. I will post up any info that I can. A friend has the z125 now but I should have it back this week. I plan on playing around with the interface software that I have to see what all I can pick up on myself.

 

I just ordered my Hoedar through Chris. Not sure how long it will take to get here, but I'm stoked... if anyone has some reading material, I would like to familiarize myself with the unit before it arrives.

 

That's the problem, there is no reading material to familiarize yourself with. It does not even arrive with a link to the software download, just an ecu in a box and an email not to start the bike after you plug it in and to call him so he can set it up. If you want to operate the system yourself, you are in for a long haul of trial and error because there is just no info available.

 

Talk to Tommy

 

I have basic instructions with the program that I downloaded to interface with the Hoedar. Let me see if I can find the link and I will post it up.

 

That would be awesome. I did some asking around and it sounds like there is no 'official' manual (which is super wierd). Those who really know the intrecate details are those who spent time with it through trial and error. They don't want to give away their hard work for free (don't blame them) as they (could) charge for the tuning services.

 

I think much gets lost in the translation of these basic instructions. They have proved useful though. Chris really needs to find someone to work with to develop a more detailed instruction manual.

 

X2, I totally agree, and would happily buy another Hoedar (and would even be willing to pay a bit more for it) if he were to get this done.

 

Just finished having Chris set up my Hoedar. I have a MNNTHBX MTake intake and Zoom loop exhaust with baffle. Rest is bone stock with ~900 miles on the motor.

We moved the rev limiter to 12k and for the life of me, I couldn't get the bike to rev over 10.5k in 3rd. I'm 170# and tucking seemed to make no difference. It sounds like I should have been able to hit 11 or 12k pretty easily... Just felt like the motor petered out.

What says you Internet? Does that sound right? I've never run the bike without a baffle... Was installed when I bought the bike (used with 300 miles).

Bad plug? Tight valves? Poor break-in? Loss of compression?

 

Lack of power to pull the higher RPM. A stock motor peaks around 8000 RPM and drops after that even with an intake & exhaust installed. Here's a dyno chart with a bone stock motor curve and one with just a pipe added. Look how much power there is at 10K RPM to move your 170 lbs. and push against air resistance. Not going to happen just by raising the limiter. You need more power or a nice big downhill to rev it that high.

 

I'm one of the few but growing Hoedar peeps needing info!

New Hoedar ECU owner in Wisconsin. looking for help. Will try the links/downloads i see here on the forum. One big question......while I'm learning this system, how do you go back to "factory Hoedar setting" if i mess something up?
Thanks guys!
Brian.

 

There is absolutely no reason to have a stock bike rev to 12k. Chris should no better.
