I use a Dell Inspiron tablet/laptop running windows 10 on a floor mount, in car 100% of time for logging and tuning. I also run a floating power supply (= no ground loops) for unlimited logging time....

The link above that jtrosky posted works for manual installation of usb drivers for win 7 and 10. I had to use it several months ago for all 3 of my computers, (2 with win 7, 1 new one with win 10)

Thanks. I installed an isolation transformer after the pure sinusoidal inverter. It's all good. No ground loops.

Realsquash - OK I will have to try that. By the way, I originally tried to set up the ADM FPCM like the CTS-V's 3 pressures, with the low flow region at 350kPa setpoint. With my injectors this didn't...

Realsquash - I had to bump up the MAP curve at lower range (3000-6000Hz, especially at lowest end) and also in 8000-10000Hz range. This was all using LTFT closed loop tuning. The adjustment at high...

The FPCM was changed last, and it allowed me to increase the fuel pressure, which was my goal. I also wasn't satisfied with the "hokey" way injector duty cycle was selected by ECM without it knowing...

I finally swapped out the factory FPCM with the ADM-programmed FPCM, which allows setting 3 fuel pressure setpoints that are selected based on fuel flow rate (no 400kPa upper limit). My understanding...

Thanks. I am now running the "supercharger fitted" option so am retuning from there. Temporarily running MAF-only tune until I have time to learn the VVE tuning here soon.

Copy SOLUTION from my other post:
Nothing worked to re-scan and get my grayed out channels back. I was preparing to uninstall and reinstall hptuners per tuning school recommendation. Then after some...

Nothing worked to re-scan and get my grayed out channels back. I was preparing to uninstall and reinstall hptuners per tuning school recommendation. Then after some digging I found working solution....

Ed, I followed your instructions. After saving the channels from the log, the software forces you to close the log before starting a new logging session. As soon as I close the log the channels are...

After using hptuners successfully for some time, with the same vehicle and computer, I just "repolled for available parameters" and lost 75% of my channels, including all 3 analog signals. The OBD2...

I just "repolled for available parameters" and lost 75% of my channels, including 3 analog signals. The OBD2 signal lost are greyed out and inaccessible and the analog (2 widebands and a pressure...

Schpenxel- is the manifold boost patch the preferred approach? I did some searching after your message the other day and I was unable to find the patch or any instructions of how to implement it. Is...

I tested "Supercharger Fitted" setting at WOT today, albeit carefully with spark advance limited to 10 degrees. Bottom line is that with that parameter enabled, then "Injector Delta Pressure" is...

I don't know if fuel line size differs from ZL1, or if there is another restriction in the line dropping more pressure (with respect to ZL1) at high flow rate.

I ordered ADM FPCM and will...

Thanks, will PM you

Thanks, will PM

Schpenxel- Log file is very large so not sure if can post, so here is a link to my dropbox folder if that's OK: https://www.dropbox.com/sh/d6hnqtn1b2rp77g/AAAvVN6PGgiIrVC9yFWWeU2ha?dl=0

This is just like my issue, also running Whippled LS3, supercharger not enabled in hptuners. 2ss Link - was the answer ever found?
Link to my issue - post: ...

JBZ - I have 2 MAP sensors: The RED font in the chart (and the top MAP gauge) labeled "MAP boost" is an aftermarket, properly scaled 4-bar absolute pressure sensor installed on the lower side of...

From a suggestion by austinb on ssforums, I increased the Fuel System Min Voltage from 13.5 to 14.5V for the lower half of the table. Interestingly the fuel pressure SAE didn't change - it must be...

Thanks for the replies, realsquash, etm351, and JBZ. I was already logging some additional signals from the same run and have plotted those in the new attached screenshot. The "Requested Fuel...

Boost is only about 8 psi. Max injector duty cycle is about 69% on 65lb/hr injectors.

I searched the old threads on fuel pressure drop on supercharged LS3 / E38 ECM - and possible solution with ADM FPCM... but found no final answer. Has anyone successfully implemented the ADM FPCM on...
