I should also note the CBR 600 ecu on the Russian site appeared to have the exact same problem, though the translation doesn't quite come out right.

Skip to 15:23 if you just want to know where to dig to find gold. Here's half an hour of me rambling about it in case anyone else wants to try this fix. But at least now I know (and the second one only took an hour to fix because I knew where to dig). It appears that these resistors were not spec'd with enough power capacity and degrade over time (or they are just low quality).Īnyways I have two working ecu's again for $3 in resistors and wayyyyy too much time picking away at rubber. 5 volt or so) and if you short a coil pack the voltage spikes, and the ecu shuts off the transistors rather than burning them up (high voltage at this area = very high amperage through the transistor). The ECU monitors this voltage (should be less than.

They are very low resistance (.25 ohm or so total) and are there to hold a little voltage on the ground side of the coil packs. These resistors are on the ground side of the transistor, and no ground = no spark. The coil packs (coil on plug) are constant power, switched ground through the 4 transistors on the heat sink. One of them went very high resistance and it was the same issue on both boards. So the (sort of) short version: if you look in the last picture, to the right of the second and third transistor from the bottom, there are two SMD resistors missing. So it was possible.incredibly tedious, but possible. Then one day scouring the internet I came a cross a site, in Russian of all things (thanks google translate), where a guy actually managed to de-pot and repair a CBR 600 ecu. Kind of disgusted with the whole thing so I just stuffed in a corner for a while.

Do a stand alone and learn how to tune? Pretty much everything is expensive, risky, or a lot of work. Do I start a collection of expensive black bricks? Do I swap the motor just because the ECU's are garbage? A 954 ECU would be almost plug and play except all the plugs are different, and I don't know that they're any better. Anyways a couple months ago it ate another one and I was back at square one. So, I bought another ECU and it ran fine for the ven years? (has it really been that long? ). If this is happening there's a very good chance it is the ECU, assuming there is power to the common side of the coil and the ECU is grounded correctly (both easily checked if you have the wiring diagram). Basically the symptoms are it will fire the injectors (easily checked by looking down the throttle bodies while cranking) but won't produce spark on any coil. I found a couple other people had also had the same thing happen while I was looking into that. The very first issue I had when I bought a salvage 929 to use the motor ended up being the ECU that was dead.

I'm just obsessed with mods and customizing.Haven't been on here in a long time, not much a forum guy these days but some of you guys helped me out huge in the past so figured I'd try and give back a little! Maybe someone will find this useful somewhere along the way. I am extremely happy with the performance as it is and has a very noticeable increase in power from 5k to 9500 rpms than it was stock. If he alters it now I will probably have to get it altered again in 4ish months. It's just that Florida weather changes so drastically twice a year I don't think it's even worth it. But like I said I think I'll just go with my dealer for the price of lunch. They promise a 2 day turn around after they receive it and if i'm not happy with they results they would flash it back to stock for free. The company also takes into account where you live and request your sea level. Looking into things asking questions and learning. But like I said I am only researching options. So I would feel comfortable getting the re-flash for a cbr300r/K&N/MGP vs my cbr300r/k&N/danmoto. The growler is a totally open system the same as mine. They do have a 300r with a K&N(which is probably the #1 performance AF everyone gets) and as for the exhaust they don't have it for my specific system, they have it for a MGP growler. They will only flash if they have the correct settings and bike. The place that does the ECU re-flash doesn't just make it up.
