When I supercharged my 408 (5.9 magnum) I installed a Hughes intake. Not long ago there was a fellow that was making a SRT4 MAP sensor to intake manifold adapter. I bought one and installed the...

That's good to know.

This might shed some light on what your questions are. There are more Youtube vids that might help as well.

Everyone knows that there isn't any love for JTEC from HP Tuners. Years ago my tuner asked for added parameters to be added for tuning the JTEC to HP Tuners and it fell on deaf ears. It amazes me...

We're lucky we got what we got with JTEC from HP Tuners. My tuner who is well known has asked for more parameters be added for JTEC but HPT just ignored him. Still there is a lot of JTEC vehicles out...

Did you ever figure it out. I'm getting the exact same thing you're having. If you have any info it would be greatly appreciated.

You might be on to something. I had to raise the RPM as well along with raising the temp to completely disable DFCO. If I remember correctly I could be wrong. Think I might disable it again and do...

Yes

Are you sure that internet was available at the time? I did the same thing couldn't figure out what it was. It showed "timed out" then it hit me.. check the wifi connection sure enough it wasn't on.

My old tuner guy told me to always have a battery charger hooked while flashing ECU. This was using SCT tuning handheld. Now I see where HPT recommends not using a battery charger while flashing....
