PE Spark Advance $OD w/16196395 using DIS

[corvairnut]

Thanks for your input and help.

My problem is NOT going into PE mode, but when in PE mode, there is no timing advance is present. I have verified with logs and also on a running engine, I have boosted the PE spark advance 12 degrees so I will hear plenty of pinging if it does work. I did increase the fast PE settings as you suggested without any change in spark advance, but the system does go in and out of PE mode based on TPS.

Just for my edification, "TPS for PE" is for PE mode with delays built in based on other factors. "TPS for fast PE" bypasses those delay factors and puts it into PE mode without question. Correct?

Thanks in advance.

I had the same issue with $0D when not running a knock sensor and bin setup like you have...
I would try a resistor on the knock input and enable code 43..and retard...you may be able to just alter the min/max KS volts in the bin.

I have an XDF with these added if you need it.
L4E6A: FCB 160 ; 16 SEC'S. HI VOLTS CK PERIOD
L4E6B FCB 230 ; 4.5 VDC A/D UPPER VOLTS LMT
L4E6C FCB 20 ; 0.390 VDC A/D LOWER VOLT LMT
L4E6D FCB 23 ; 4 DEG, KNK FAIL RETARD

Made the changes and made no difference at all... but I do now have the knock sensor up and running. I quit using the knock sensor because of faults knocks I get on the corvair engine.... its a little noisey.
