Well dang I just tried and your right. I'll go back and change them

Take that back for some reason it's giving me this flag. But not sure I even edited anything that recently. Guess I'll have to wait and see if it clears and then change the photos out

Ok
Maiden flight in to work. I've got an intermittent misfire. I'll do some troubleshooting through the week as I'm back at work. It's not bad but it's there. I did a lot of connector work obviously for the change. So I'll keep everyone posted on my results.

Well good news bad news.
Good, is that the miss has been cleared. Took the PCV out of the loop and misfires gone.
Bad, PCV seems to be the culprit. I'm suspecting a grounding issue.
The system has 2 ground wires one is the box/system ground black
The second is a digital ground Black/white tracer. Under normal operation you can tie them both together. But if your wanting to sample say a TPS or MAP signal you should tie the digital ground into the sensors ground. This ensures they are both seeing the same ground plane.
So I'll do some more testing. I'm very confident this PCV will work. That's another reason I went this route
It's a proven system on the 01 and up. So it should here as well.

So does that mean undoing the the ground that you splice and using one or two of the spare plug holes for a separate grounds.
I looked at loom pics and seen the later bird has a extra plug in the injection harness.

Not sure just yet. I'm thinking that I need to tie the black white wire on the pcv to the ground going back to the ECM. Our earlier FI's have what I suspect are 2 digital grounds at the ECM. Still investigating. I don't think we'll need to populate more ports in the connector but having 3 blanks may be an option to use. We'll see I have an old harness here I'll untape and chase out the wires. And I'll get back with my results.

So did some more work with the PCV plugged in. What is happening is I am getting a spike in the Injector signals and in the rpm. I can see the injector signals on the POD 300 and the tach signal on the laptop running the PC tune table.

Took an old harness apart, man there's a crap load of tape. I traced each Black/White trace wire out and verified both harnesses ring out identical.

So tomorrow I'm going to swap out PCV's as I bought 2 of them one for mine and my son's bike. I'll swap in the other one and see if the symptoms change.

Then I'm going to install the factory 01 Injector harness and see what happens.

The last test will be to tie the digital ground off the PCV to the BB's digital ground line of which we have going back to the computer. I am hoping this is the problem and why it's spiking.

Test bed Engine set but hasn't been fired in so long injectors are acting up. Gonna let the rail set overnight charged and see if it clears it out went from nothing to hitting on at least one after about 10 minutes of fuel soak. Hopefully the others free up overnight.

Getting a break up in the system running the PCV's. This is a 01 engine and ECU complete so the plug in is 100% to this setup. So I want to make sure it's not the bike reacting badly. See my earlier posts for more info.

Well overnight set did it. She's running smooth as silk on all 4. So now we'll swap in the PC's and see how they act.

Not good news I'm afraid. The Second Gen BB's use a higher primary coil voltage on the trigger wire. It's actually almost twice as high as the Gen 1. So the PCV is causing the Tach voltage to jump to 20 volt signal into the Gen1 computer when it should be 5v and it's not happy about it. The PCV also does not like the lower Coil trigger voltage. This in combination is creating a false rpm count and making the system glitch causing the tach signal to bounce extremely high. This in turn cranks up the duty cycle and injector duration only for a split second. What then happens I believe is the ECM trips off for a split second shutting off fuel and causing an injector misfire. I can see this with the AFR operating because it spikes high for a split second as well. Telling me injectors are being shut down, if it was spark the AFR would spike low. It hasn't popped anything in my ECM yet but over a long period I can't say. And I'm not willing to take a chance with an extended running test.

Now there is a possible solution, find a Gen2 computer to run the system. We suspect there aren't any issues because the bike and the spare engine both run with either computer installed. IE Gen2 computer in Gen1 system or Gen1 computer in Gen2 system. The only thing is the temp sensor which should be a simple swap out for the appropriate gauge. The stickler is the FI indicator. There are two options for this on the Analog dash 1. Sourcing in a LED bulb for the FI port without a load resistor. 2. Would be a digital relay controlling a 12v source. Because the Gen2 runs at 5 volts or nothing. The Gen1 needs 12 volts. The 3rd option is to convert to a digital dash. I am ordering a Gen2 gauge harness and sensor for my son's BB as he wants to convert over gauge sets anyway. Once we have the harness I can verify there aren't any any FI faults. Then I'll run it for a week or so with the modified FI indicator. If all goes well then I'll install the PCV and start tuning.

I was hoping this would be a straight swap over but alas the curse of customization is that sometimes it doesn't go completely to plan RATS. But it does look doable albeit a bit more involved than originally thought. At this point I would probably go down the CBR1000 path some others have done to adapt in a PCV. It's not as involved as this route morphed into. My plan is to continue down this path given my outlay and parts involved. I am very confident it is a working solution. I know one member has ordered the connectors and at this point I would say to go the CBR1000 route at this point.

Nah
More like a tinkerer that can't leave well enough alone and sometimes that gets me in trouble 😂. Luckily I have a very tolerant misses and some dumb luck.
This mod didn't turn out the way I hoped but at least it's not a total loss🙄
