Please help to transcript abbreviations and assignment of flags:
KAFOPTC: Air/Fuel Option Word - Bit 7 - SPKct
KAFOPTC: Air/Fuel Option Word - Bit 6 - SPKss
KAFOPTC: Air/Fuel Option Word - Bit 3 - Crnk+
KAFOPTC: Air/Fuel Option Word - Bit 2 - BLMid
KAFOPTC: Air/Fuel Option Word - Bit 1 - BFinh
KAFOPTC: Air/Fuel Option Word - Bit 0 - BPWmd
KTBPFOPT: TBI/PFI Option Flag - Bit 6 - exBPW
KTBPFOPT: TBI/PFI Option Flag - Bit 5 - VElrn
KTBPFOPT: TBI/PFI Option Flag - Bit 4 - ACSPt
KTBPFOPT: TBI/PFI Option Flag - Bit 1 - Decay
KTBPFOPT: TBI/PFI Option Flag - Bit 0 - AEaft
This is for $5D.xdf
Sorry, I am not English-speaking man

The flag has a bit assignment, 8bits to a byte, though information is useless as there is no address

KAFOPTC: Air/Fuel Option Word - Bit 7 - SPKct = Bypass spark with closed throttle
KAFOPTC: Air/Fuel Option Word - Bit 6 - SPKss = Bypass spark during stall saver
KAFOPTC: Air/Fuel Option Word - Bit 3 - Crnk+ = Crank input active high (for backfire inhibit)
KAFOPTC: Air/Fuel Option Word - Bit 2 - BLMid = Allow open loop BLM adjustment
KAFOPTC: Air/Fuel Option Word - Bit 1 - BFinh = Backfire inhibit logic (V6)
KAFOPTC: Air/Fuel Option Word - Bit 0 - BPWmd = Use BPW modification instead of AFR
KTBPFOPT: TBI/PFI Option Flag - Bit 6 - exBPW = External BPW modification
KTBPFOPT: TBI/PFI Option Flag - Bit 5 - VElrn = VE learn (factory learn code removed on 5D)
KTBPFOPT: TBI/PFI Option Flag - Bit 4 - ACSPt = Different coolant sensor
KTBPFOPT: TBI/PFI Option Flag - Bit 1 - Decay = Decay transient fuel per rev
KTBPFOPT: TBI/PFI Option Flag - Bit 0 - AEaft = Use AE after start enrichment

Thank you so much!
With your permission, a few questions:
- If I set a flag "KTBPFOPT: TBI/PFI Option Flag - Bit 7 - TBI " ($5D.xdf) can I use low impedance injector (TBI)?

- what tables adjust engine warming?

I plan to adjust a nonnative engine (1,6L, do not laugh...) using AMXY0662.bin (2.0L PFI JE (Holden Camira), $5D.xdf) using TBI.

Me more suitable $35.bin but never found $35.xdf.
Tried $54, strong enrichment, especially in the warm-up, very few settings.
Adjustment tables F56, F57B did not help.

Yes you can use low impedance injectors for TBI but not for MPI.

Also Have a look at 12P here: http://pcmhacking.net/forums/viewtopic.php?f=27&t=356
It runs on the same hardware ('808 or '165 computer) but if you wish to log it then you need a hardware mod on the '808 for high speed comms. You do not need 12P but you might decide its better.

Thank You!
Looked $12P,very impressive.
With $12P can not be used TBI, I understand ?

[Charlescrown]

Yes it can. I am using it on my Mitsubishi Starion TBI. The tuning was a bit different to multi point but it's all running very well. I still need to do some final tuning but to me that never ends.

See here for the resistor pack settings: http://pcmhacking.net/forums/viewtopic. ... t=10#p6850

[fad2629]

thanks, I will learn.
If I have netres 4 cyl TBI engine, the 12P will work correctly for TBI, I understand?

[Charlescrown]

I don't know if it makes any difference as long as you have a 4 cyl memcal. I think it's only different if it goes into limp mode but maybe someone else might enlighten me on that. My Starion has bigger injectors so I have doubts it would run very well in limp mode anyway. 12P is a fantastic program and you will find a lot of knowledge here on this forum.
