My Coober Power Kit is supposed to arrive tomorrow, so I did most of the teardown this morning...





I will update this thread with more pics when the Coober arrives and I start actually installing it.

Haha... Coober says this thing takes 6-10 minutes to install. It took me 1/2 hour just to get the plastic bits off and loosen and raise the tank.

After another hour of disconnecting and trying to move stuff, I have exactly ONE of the 12 connectors hooked up (TPS) and even that one is only one of the pair. I have it plugged into the TPS connector, but have not been able to connect the other 1/2 of the pair to the OEM connector. There is no room.

I'll get it, but this is a MAJOR PITA to install.

OK, got both sides of the TPS connected. It's really hot in my garage, gotta take a break.

6-10 minutes, my ass.

Got the ignition coils hooked up and the crank sensor. Decided to remove the fuel tank completely to give me more room to work. At this rate, I should have this done in no more than 2 or 3 weeks.

Sheesh!

I'll finish it in the morning. It's about 95F in the garage, it will be cool in the morning.

When I installed the PCV, I fully removed the tank as well. You really have to. There is very little space in the engine compartment, and the 2 coil connections were the most difficult for my fat hands. Are you going to eliminate the charcoal canister while you're in there? It's a good time to do it, if you have the info and parts to do it. Good luck and thanks for the write up.

I cheated and ran one of the TPS wires outside the TPS unit - Wrapped in black tape.
The bugger being the first time I ran the wires it went in first time.

MAKE SURE YOU GET THE COIL PLUG DONE PROPERLY - they will go in reversed - Match the wire colors.

In hindsight - I wish I had removed the tank too.

And definitely wish I had a lift!.

I was very careful with that. It appears the connectors have changed because you cannot connect them wrong, I tried. And the wire colors in the Coober harness do not match the OEM colors.

And definitely wish I had a lift!.
I agree, the lift is wonderful.

No, I'll leave it in on this bike. I removed it on my SDR because it gave me storage space. On this bike it wouldn't give me anything but a tiny weight loss, so I will leave it.

Got it all back together. It won't start. Displaying an MTC error. Exhaust smells strongly of raw fuel. In about 10 starting attempts, got one pop.

Barbagris warned about the ignition coils being possible to connect wrong, and although I was very careful and tried hard to get them right, Coober does not make it any easier by using their own totally unrelated wiring colors in the matching plugs.

Oh well. Tear it down again. This job has been a nightmare. PCV is way easier to install.

Removed the tank and the inner right side cover again to allow access to the ignition coil connectors. Now fighting again to get them unsnapped from the metal brackets they are on so I can inspect the connectors.

I wrote to Coober USA and they also think one of the ignition connectors could be plugged in wrong. Not sure why that would cause an MTC error. They also offered to give me a return label and 100% refund. I may take them up on that and just put it back to stock.

I'm going to return it to stock and send it back for a refund. I've seen enough.

True - but it does less!.

Start connecting up other wires to get map/gear - MAP pressure input - temp input and it soon turns into a rat's-nest-clusterfuk unless you are fastidious about wire coding and shielding. Add Auto-Tune and the POD and all of a sudden it is a real PITA to remember what wire is what. Ask me how I know :unsure::whistle::coffee:

I don't like using piggy-back devices of any kind. I'll wait for Shiv at OFT to finish mapping this bike. Then it will be a simple matter of flashing the ECU in about 5 minutes, with the ability to go back to the stock map in another 5 minutes. No taking half the bike apart to install, connect one plug, that's it. A piggy-back device cannot do what a flash can do; it's just that simple. I have the OFT for my Super Duke R, and it's flawless. I realize you had issues, but I didn't.

I never had OFT on my SDR. I had PCV & AutoTune on my SDR and it was fantastic. OFT was on my Tuono, and it was nasty, really rough at small throttle openings, and they would not even ack my requests for a fix.

I'm glad it works great for you on your SDR.

OK, stick a fork in me, I'm done. After several more hours disassembly, checking / troubleshooting and reassembly, same thing. Won't start, has a "TC!" error on the display.

I am going to uninstall the whole mess tomorrow and return it to stock. I don't need this kind of grief. Sending it back for a refund.

Wow! I had no idea the install was so involved. I thought you just had to remove the pillion cover and plug it in.
That's what they'd like you to think. They told me:

"actually there is no install manual at all inside the ecu box. installation of the ecu on the 890 duke, takes normally between 6 and 10 minutes. its only 12 srews, 2 ziptie and that's it. only tool you need is torx 25 and side cutter"

BS!!! The only thing true there is that there are no instructions in the box. If you take the tank off (which is completely necessary for me with my large hands which now have cuts all over them) there are about 30 "srews", and it takes a T30 Torx, not a T25. Oh the side cutter part is right, but there are four zipties to cut and replace not two.

Ho maan, I hope you get it sorted/installed, with all that effort you put in. Hopefully others’ who’ve done it could chime in?
Nobody's done it before in the USA, at least not on an 890. I got the first one.

I was set to buy a coober for my 790 but just about everything they put out smacks of marketing B/S, including the continual rubbishing of their competitors products. At this stage I am going to give it a miss. Be interesting to see how their comments
on 890 oil issues plays out.

Totally what puts me off of coober.

The guy at Coober USA (Aaron) is great, very responsive. But he is dealing with the Coober EU guys who are pretty unhelpful.

I agree, I smell lots of marketing BS here. Even their own dyno chart with their unit installed shows pretty poor performance numbers, although it does fatten up the midrange. I was never able to get a straight answer out of Coober EU about the small throttle / low RPM stuff other than this:

we have fix the closed loop are to a certain level, to still keep the piston expansion. the bike become bit more smooth in the bottom and mid range.

Pretty vague answer, IMO. Anyway, I'm done with them. I uninstalled it again this morning and have it packaged up ready to go back.

Got it all returned to stock with the Coober stuff uninstalled. Fired right up, runs great, no errors.

I had zero issues with the PCV I installed.
Power Commander for the win! (Jut kidding)

Yep I have installed several PCV on several different bikes. Worked great on all of them and they were way easier to install than this thing.

In general, on the 890 what is the desired result(s) of installing a fueling kit? More power? Fix a fueling issue? Aftermarket exhaust fuel modifications? The only fueling anomaly (being really picky) on my bike is that it's a bit fluffy right off idle in first gear pulling away but it's very minor. Other than that, it fuels great everywhere.

Before buying my 890, I looked at a local 790 with an Akrapovic and Coober. When the guy started it up, it fired up only on the third or fourth try and then he had to hold the throttle open manually to keep it running. He said it runs great once warmed up.

I walked away.

I was looking for improved rideability. The bike in stock form has quite a power dip in the 5k to 6k rpm range, and is rough at very small throttle openings and low rpm. I don't care about a few HP more at redline, because I seldom wind in up that high and seldom run at full throttle. I might do a PCV for this, but won't be using a Coober.

I have no wish, here anyway, to be classified the great satan. I may be his advocate however - rather often too.

My Coober didn't work first time either - so I took it off. Breathed deeply (rather annoyed), and spoke with Coober (albeit via WINGS).
Refitted it , being very very careful with all connectors and it fired straight up. The difference is notable.
There are four ignition connectors and any one of them reversed will stop the blighter starting.
It's like Gregor Johann Mendel all over, just reversed.

imo worth a second try. It is designed to address EXACTLY that weird mid-range bit.

It's NOT a fueling solution. It cannot be as it has zero access to the AFR values.

And for those dissing it - what other Coober solutions have you seen.? - Seriously! - Because prior to buying a KTM I'd never heard of them. I am always open to data.

Interesting that the AR ATOM is the same box and nobody has a go at them. Well not that I have seen.

I suspect language support is the issue - and oddly (maybe not) it seems to be more an issue in non-German speaking countries. YES! - I do speak German.

In France it seems to be a defacto recommendation from KTM dealers.
Here (Spain) we tend to be more Catholic than the Pope - so if the EU says no add-ons, well no add-ons it is. But my dealer took one look and winked (conspiratorially).

Still, we all have to learn from our experiences, and decide accordingly.
