    Has anyone successfully gotten both ZT4 channels to display? I would like to be able to see them in chart vs time and then also in the graph. I am assuming if I can get them in the graph, I can do...

    Thank you! An interchiller is on my list of strong maybes down the road. I have attached a log of your tweaked tune. It was better but still fell almost to zero once and did fall all the way at...

    Yes, you would think so but mine is not having any issues. If and when I need a new pump, I will probably go to a Fore setup unless I found a good deal on another OEM pump. The OEM ZR1 pump is a...

    Thank you for the reply. Upon further looking into this, I did speak with one of the tuners. I was told the sensor still will not allow the reading of higher than 255kPa but does seem to live...
  7. 3.5 bar MAP sensor on a ZR1 to report over 255kpa

    I know of two people who are successfully doing this. The issue is they aren't tuners and cannot tell me what the tune settings are for the new MAP. They said their tuners input the sensor's...

    You can change the commanded duty cycle. Mine has been set at 99.5% forever. I have a lean spike upon sudden WOT. I have spoken to some well known tuners and was told there is nothing that can be...

    Although the file link shows .hpl as the extension, when you download it, it downloads as .hpt (the actual tune) not as the log. Therefore, it won't open in the scanner, only the editor.

    Quick update, it is getting there. I just don't have much time (about 1-2 hours a week it seems) to do anything with it. I was able to get some more logs and make tune changes over the weekend. What...

    Yes, the headers were removed and new GM OEM gaskets were used when reinstalled.

    I noticed the voltage too.

    Tomorrow, I am going to switch the O2 wiring to see if that makes a difference.
