14.12 programmed into the lc1
0v=9.59
5v=19.19
and the 1v and 2v did as well

That still leaves the same expression as mr.prick gave. So you can program the 14.12 setting into the lm-1 & use mr.pricks expression in a calc pid to give you the correct AFR on both.
ute.
this is what joecar came up with
Based on the LC-1 being programmed for gas being 14.7, here's what I come up with:
GAS (stoich 14.63): {EXT.AD1} * 1.990 + 9.952
E10 (stoich 14.12): {EXT.AD1} * 1.921 + 9.605
E85 (stoich 9.78): {EXT.AD1} * 1.331 + 6.653
So for example, if the LC-1 was reporting 2.35V those equations would give:
gas AFR = 14.629
E10 AFR = 14.119
E85 AFR = 9.781
ute,
this is what mr.prick came up with
({EXT.AD1}*1.9203)+9.602
2.35 volts = 14.12 AFR
2.35 volts = 1.00 Lambda
and joecar
E10 (stoich 14.12): {EXT.AD1} * 1.921 + 9.605
pretty close if u ask me...
The PCM will not have 14.12 in {B3601} it will be 14.12xxx
Joe may have went the extra mile and did the proper conversion,
I used 14.12
If you want it perfect copy and paste {B3601} here.
Thanks.
I think this is a subject that gets overlooked.
It makes serial WBO2 that much more of a selling point for EFILive. :)
mr.prick. I can verify that the pcm uses B3601 in calculating the pulsewidth. By using the RR in emulation mode at idle & first increasing B3601 to 18.1 & then decreasing to10:1 the idle was clearly affected. Check out around frame 350, where pw increases while commanded EQ stays constant & commanded AFR also changes.
This proves that
1 the pcm uses EQ in its tables.
2 that commanded AFR is a calculated value between whichever commanded fuel table is active & B3601. Hopefully this will clear up a few issues.
Sorry for making this thread go off on a bit of a tangent WHYTRYZ06 but I believe this is important information in relation to the original question.
Mick, in that log commanded AFR went lean & IBPW went up :confused: although
IBPW only went up a little.
WBO2 was not present, it would have been interesting to see if that changed as well.
ECT was low & high commanded EQ what happens in closed loop?
The RR sure does come in handy for experiment like these. :)
