Progress Thread finally tuning (and more)

Yeah the base timing is 10 with spout removed. Additionally, the only thing I’ve done with idle is set the physical base idle as per the standard procedure and slot the TPS to get .98v at idle. Even though Harrison goes through a bunch of stuff on idle and correcting for problems, I’ve not needed to do anything with that. Idle wise it’s now better than ever with stock settings.
Am I see'n a yellw wire nut over there?I’ve got the scaling equation ready. For PLX its voltage x 2+10. In the picture you see the thin green wire that id the analog from the PLX. I’ve got it connected to the pin 27 location on the EGR plug. In the picture I’m back stabbing the harness plug to verify the voltage making through my connections. 2.33v x 2 is 4.66. 4.66 + 10 =14.66. My wideband reads 14.5 at this idle status so close enough for me. Just can’t figure out how to get it displayed on the data log
Did I work on that junk??
You know I don't understand most of that 'puter crap but I'm hang'n.
Wait'n for those WHOOOOSH sounds and road strip'n
Yeah I used the wire nut because the data log hookup for wideband is temporary. I’m not going to leave the Quarterhorse chip in permanently so when I change it for the J3v2 chip I won’t be able to data log without pulling the EEC and putting QH back in anyway. So, I’m borrowing the EGR circuit for tuning purposes but when I’m done tuning I’ll be putting the EGR back in service. I’ve cut nothing on the factory harness so the EGR will be back in service as if it were never messed with. Hence, the wire nut for temporary use only.
