A question is, under insite, it says that you can lose up to 21000 psi on the leak test. I read in here that this is a misprint and according to me Rawze that you should not have more than 4000 psi drop. Is this correct.
...

yeah.. its supposed to be 4,000 psi on 60 seconds. That is the original spec.. and I suspect the red engine maker changed it to have less warranty claims?.. but one never knows why it was changed to that.

In any event, 21k psi on one minute is a disaster waiting to eat up a cylinder after a while. Seen many cylinder failures due to injector(s) leaking.

- As far as finding out if there something holding the fuel back, Insite is almost useless for this. The Calterm software is needed for actually determining what is going on. Here is a screen file on what to monitor...

Get some desktop recording software up and going, and then set the screen up in CT. Record it into a video, and then it can be played back moment by moment as it acts up.

The fuel control state and a few others is the thing to monitor in particular. Let me know what the value is while its acting up, and I will tell you what system or circuit is holding the fuel back at that moment.

The next question.. is it De-Mandateed?... and if so... who did it?... as more than 90% of all de-mandates are bad + harmful to the engine. This even before anyone adds any power to it.

Use the CT software to copy the program from the ecm and e-mail it to me for a proper review of what someone did in there. That is how someone moves forward if they have a de-mandate program.
