Re: "flat response" knock sensors

Thanks! I'll give those a look. So far, all I know for sure is that the wiring harness that I used isn't going to work. It grounds one lead from the sensor and runs the other lead to the PCM. However I'm pretty certain that both leads from each sensor need to go to dual inputs on the PCM (four PCM p...

"Permission to upload kernel was denied."

During the flash process, we: * unlock the PCM * switch to 4x * request permission to upload the kernel That last step used to fail for me very rarely, and power cycling almost fixed it (sometimes I might have to power cycle it a couple times, but that was rare). Today it's been happening more often...

Re: Mother of all 7603 XDF files

Thanks for the info about the checksum stuff. Universal patcher sounded easier though, so I went with that. I set the new time to 1 second, out of concern that setting it zero might lead to an off-by-one error somewhere - it probably won't, but I'm paranoid. Today I tested it in the car, and it work...

Re: Mother of all 7603 XDF files

I'm pretty sure I found the parameter that causes the 10 second wait before you can unlock the PCM, but when I change it, the check sum doesn't get updated, so I haven't been able to test it yet. Does anyone know how to get TunerPro to fix the checksums outside the calibration section? UnlockDelay.p...

Re: PCM Hammer - CAN BUS Communications

Now that I’ve gotten a prototype read kernel working for the E92 ECU ... You absolute legend. :) There's work underway now (or, last time I checked in, which was an embarrassingly long time ago) to support more VPW-based ECUs, and it would be good to wrap that up before tackling a CAN ECU, but it's...

Re: PCMLogger: can't log all cyls for misfire?

I'm happy to fix this, but can someone give me the specifics of what needs to be changed?

Also I'm told that after a clean install, the logger needs to be restarted after picking the interface, and I'll try to get both fixed this weekend.

Re: P04 PCM's

I kinda started with BASIC on a Commodore PET and then C64, but didn't do anything memorable with it. The big step forward was in college when I wrote some BASIC to do some math for subwoofers and subwoofer enclosures, because my friends and I were putting loud stereos in our cars at the time and I ...

Re: reflash P59 tac module

also, do you happen to know if a pcm can be recovered from messing with the ETC settings within the red folder of EFIlive? [...] edit- popped the cover off and grounded the reset pad and was able to write entire (clone) another P59 dump I have on it using PCM hammer. so back in business. :punk: Tha...

Re: 0411PCM 5v input 12v output at certain range

You might be able to use the CAGS / skip-shift output for this.
It's a binary output, and the parameters that control it use both RPM and MAP.
