2000 NB1 new MS3 Brain built, cranks/pops, sync loss31&32 and humming sound
I'm getting the same exactly symptoms as the thread above, except no humming noise.
Backstory: '99 has been running on a DIYPNP for years and just switched to an MS3+MS3x V3.0. I built it using a combo of the assembly manual and Westfield MX5's manual. ID1000's, LS2 coils, pretty much everything else is stock.
When I first tested cranking signal, I got a few counts of sync loss, then nothing after that. Checked again, no sync loss. No start, so I started tuning crank pw. It always had the weird popping noise as described in the thread above, so I knew something was up. Checked diagnostic tab and there was sync loss. A combo of 31 and 32 codes. Below are the evidence of good signal, then sync loss.
So I dug into the case, and checked voltages again on cam and crank circuits. Cam sensor sees 2.4V and cannot be adjusted higher. Crank sensor sees 2.8V. I saw in Franks guided that he installs a pullup between the left hole of R13 and right hole of R45. I have mine built to the manual with both R13 and R45 populated (and all other resistors for that matter). I also have the R52 pot populated instead of a fixed resistor. The jumpers I have in place go along with Franks guide. Pictures of my board are below.
I then found the thread I linked to above (and the one linked to in that thread) and tried falling edge capture. It cranked smoothly (no popping) but there was a ton of sync errors and no RPM.
Any ideas? Thanks in advance.
