Re: Data Log channels & gauges
i did a pull request. I didn't add it to the gauges as it's probably not needed there.

Re: Data Log channels & gauges
Is it possible to add the injector phase angle to logging? I didn’t see it in there.

Re: Honda B20 CRV #43
I’ve made a couple trips now and it runs great when warmed up. The running and driving tune is pretty close. I’m having troubles with cold startups, I see no rpm in console or tunerstudio when cranking cold, if I pre warm the engine it works fine...... I will post the error log from console in a bit.

Re: Honda B20 CRV
Alright, I went and got a quick video:
The video is very dark, but i have to prove it's working! I can't wait to get a wideband O2 in this and start getting it tuned up.

Re: Honda B20 CRV
It Runs! I got it to start and idle today while on my lunch break at work. I need to get a video of it to post. I ended up with a 95 degree TDC offset value. I think with the distributor it's possible for me to be off by +/- 180 engine degrees off of Cyl 1 TDC when using a timing light. I think i'm ...

Re: Honda B20 CRV
the 250 rpm was without plugs in, maybe the starter isn't weak. I get about 190 rpm with the plugs installed. I believe i have the spark configured correctly now as single coil, not wasted. I took out all the plugs and laid them on the valve cover with the wires connected, all 4 would spark, and it ...

Re: Honda B20 CRV
Looks like it! ~250 rpm but I believe that because the starter sounds pretty weak. I went to the Honda 1 + 24 decoder instead of the custom with VVT, and now it picks up the front edge of the 1 pulse reliably as TDC. I’m working on spark now, I get spark on cyl 1 but it seems to be occurring every 1...

So with CAM signal flipped, everything is looking pretty good. This still has the 2.7k across the CAM terminals, but no more pull to GND:

Re: Honda B20 CRV
I think i'm getting close to having the 1 pulse working. I read in some of the other Honda threads that there are possibly issues with long VR pulses. Here is the sniffer with a 2.7k across the CAM terminals, seems to have eliminated some noise: with_2.7k on cam.png And here is 2.7k across, with add...

Re: Honda B20 CRV
So i swapped the 4 pulse distributor signal out for the 1 pulse and now everything looks worse. Sniffer attached.
I put the settings to do the 24 pulse only, and that one still looked good. So i'm not sure why my 1 pulse cam signal is having troubles.
Time to double check the wiring...

Re: no lift shift (NLS)
Alright, so i grabbed some logs. This is actually the first time i''ve looked at a log of the NLS. The RPM does not seem to drop when i clutch in? it goes up and hits the fuel cut. Either way, here are some logs of the fuel cut in some 2,3,4 gear pulls. Also if you don't feel like plotting, here is ...

Re: no lift shift (NLS)
I believe that the TPS > threshold would be very important to avoid getting the fuel cut during rev-match downshifts.
I have NLS on my Evo, and in that application the fuel cut works well. I would be able to provide some data showing it in action on that platform if it helps give insight?

Re: Honda B20 CRV
Finally finished assembling the board. The power supply works and i'm getting ~4.89V. At first i could not install W23 as the other side was connected to ground. I found that i accidentally soldered two pins on the VR chip together causing this. Once that was fixed up i installed W23 and JP01 to boo...

Re: Honda B20 CRV
Thank you for the direction guys. I basically want to populate everything, all inputs, outputs, knock sensing, CAN, etc.
I'll go through the schematics and make sure i have the components for each installed.

Re: Dual wideband?
For the best efficiency of a 3-way cat, a mixture of both rich and lean conditions are required. That is why closed loop fueling in an OEM application is always going back and forth between rich and lean, and it does not just stay at 14.7. A simple 2 parameter way to describe the control strategy is...

Not really any performance goals, just would like to test out this platform for use on future projects. First step was buy a 0.5 board kit. I've got the kit in hand and everything looks great...

Hello everyone
Just checking in. I have an evo that i tune myself, and i'm looking to get a Frankenso up and running in my Honda.
Got the kit ordered! can't wait until it gets here and i can dig in on the assembly.
