View Full Version : New to EFI Live and have pid ??'s

I was using the "other" tuner before, and with efi live I noticed my Map sensor reads differently, as well as my IDC is way off (like 24% when I was 85% in HPT).

In the pid list it looks like IDC is a calc, instead of OBD? Is there a E67 pid that reads IDC a little closer to what I think it should be?

The map scaler gave me a hard PCM limit when I try to scale it like I had it 255 before. I've tried the scaler both ways (I'[m using the 2.5 bar LSJ map with temp) and get the same KPA readings from the pids.

I appreciate any help you could offer..


Thanks
Jim

Jim, that would be my fault, I set the software limit to 255, most sensors don't need to be scaled above that. That was before I just learned (form you) about the LSJ sensor needing to be scaled to 270.
Let me know what OS you are tuning there and I'll send you a .cal file update.

There is no direct Injector Duty Cycle PID from the ECM, it's calcuated from GM.INJPWB1 & GM.INJPWB2, if possible can you please forward a log on to support@efilive.com and we can take a look at the odd readings.

Cheers,
Ross

Ross,
I will forward a scan to you once I get home with my laptop. My IDC % is running like 24% when the other tuner is 87-90% ish.

The error I get when I scale the E67 above 188 kpa on the Map is a hard code VCM error. It reads something like the VCM may be hard coded with a limit, and calibrating it above that limit will not affect a hard boundry set in the VCM.

My understanding from one of your posts in the VVE thread that this 2.5 bar LSJ map should be tuned as a 3 bar?
If that's so how do I get around the hard code limits on MAP scale?

I am currently using the 2 bar VVE tables, however I am worried about the scale difference and what the scanner shows for KPA etc I get 109 KPA in your scanner whereas I used to get 163-170 KPA in the other one. I am making between 10.5-12 lbs of boost (on a manual gauge) depending on weather and temp etc. The 160-170 KPA number makes more sense to me as isn't atmosphere 101.325 kPa or 14.7 lbf/sq depending on baro etc? So 170 KPA reading should be about 10 PSI which would jive with my boost gauge.

I will post the exact error later.

Thanks
Jim

I have had same problem with L98/E38....very strange injector pulse widths and duty cycle figures. Not really a problem as injectors are big enough I was just curious whilst tuning to see figures and was quite shocked.All I was logging was injector pw and calc duty cycle..I figure it must be just a scaling problem.

Ross,
My OS is 12605331
OS ID AB
Calibration 12605548
BCC YNAC

Thanks

P.S. I emailed that log file with the weird pid readings.

my OS shows: 12610013 ID AA
Calibration: 12610012
BCC: YNUN

My V VE table stock.
2666

Care to compare. I assume they are the same since we're both 2.4L LE5s, I just have a kappa.

RossI sent in the scan log in and posted my os any word on the new cal file?

Sorry for the delay Jim,
Attached is the updated .cal file.
Save in to - \Program Files\EFILive\V7.5\Calibrations\E67

I think you should set B2101 to 270, then B2103 to -1.65. I am basing this on the same parameters in the P12 LSJ tune.

Cheers,
Ross

Ross,
I downloaded that .cal file and overwrote the old one.

Do I need to do anything else to get that .cal to work?
Also will I now be using the 3 bar VVE tables once the scale is correct?

Ross,
I can't get the scanner to work now.:bash:

I just sent the error log to you.
