COS#3 ... Max MAP = 105kpa in the scanner?

I have a 2bar map and am running COS#3. I noticed today that I slipped while trying to log some 0.0psi and hit 1-2psi a few times, which should have put me up into the 115kpa cells. In the scanner, however, the ben table only showed up to 105kpa (I made my labels through 285) and the max logged in the dashboard is also 105kpa and not 113kpa. The SAE MAP pid says it loggs to 255kpa...

MY C6301 is 194.0039 which makes my baro reading match the local ambient pressure.

Am I missing something here?

Erik,which PID are you reading? And did you setup a custom map in EFILive with the proper KPA column headings.. copy and paste with labels from Flashscan?

I'm using (0) Intake Manifold Absolute Pressure KPA

Hey Dennis,

I'm using: Intake Manifold Absolute Pressure reading the SAE.MAP

I did set up custom BEN map, and copied the VE table map labels, and concatenated the Boost VE map labels so it shows 15-285kpa.

My idea was to set my VE table and use the same map for autotuning the boost ve table. The problem isn't localized to the BEN map, however -- my MAP guage in the dashboard (which also reads (0) Intake MAP based on the SAE.MAP) also seems to cap at 105.

What I'm wondering is if the sampling rate is too low to see these peaks.

Not sure I can help... Try switching to the GM.MAP or GM.BOOST

Keep me posted on how you get it to work.

Erik,

Do you have a log file with this problem you could please send to me....

Email sent. Thanks Ross

Any outcome from this?? Sounds like similiar problems I had they I never straightend out!

Erik,

Can you please do another log for me with less PID's selected (you have too many to do AutoVE tuning).
Please just log -
SAE.RPM
SAE.MAP
SAE.TP
SAE.VSS
And switch the scanner over to Stream-Fast mode
Edit >> Properties >> Logging.
Then resend the log file to me.

Thanks,
Ross

I'll make another log and will hold 2 psi for a bit to make sure it isn't a sample rate issue.


Is there a limit to the number of pids for autotuning? The guide just says something like "these are the minimum pids you need, you may want more" etc. Do more pids = slower sample rate?

O.K, that's not 100% clear is it.
You ideally want to run fast-stream mode, then keep the number of channels below 24, once you go above that then things slow down. That's a PCM issue, the GM programmers only assign the PCM 'x' amount of time to perform diagnostic data, afterall, I guess running the engine is more important than scantool data!.
