My custom OS does not have OLFA, it has a A0008 file. The A0008 states its a multiplier. Is this truely a multiplier or is it a divider?
Thanks,
Glenn

It is a multiplier. I'm going to assume that your display units are AFR or EQ Ratio , and that the commanded AFR is 14.63:1 (or EQ Ratio of 1.0) for the example.
- A multiplier of 1.00 the commanded AFR will be 14.63:1
- A multiplier of 1.20 the commanded AFR will be 12.19:1 (Richer)
- A multiplier of 0.80 the commanded AFR will be 18.29:1 (Leaner)
The multiplier is for enrichment (richening the mixture) and the lower the AFR numbers are richer the mixture.
Hope that makes sense.

how is 0.80*14.629=18.29 a multiplication? i'd call it a division

If you look at it on EQ basis, it's a multiplierOriginally Posted by redhardsupra

This is the key.Originally Posted by Garry
It multiplies the current EQ to get the target EQ; the current EQ equals 14.63 divided by current AFR.
AFR = 14.63 / EQ = 14.63 * Lambda
or
EQ = 14.63 / AFR = 1 / Lambda
EQ, Lambda, AFR are all units of how much air/fuel.
A008 is a multipler in the sense that it multiplies current EQ to give target EQ.
Like Tordne said, the higher numbers are richer.
Edit: the more I write here, the muddier it is becoming...

Okay, I am going to try what Tordne said and see what happens.
The whole multiplier/division thing confuses me; however, I understand what is being stated!
I will let you know how it goes.
Thanks for all of the help!

Thats what i am trying to wrap my head around...lol. My commanded AFR is 14.70:1 and my multiplier (for a specific cell) is 1.0229. 14.70 x 1.0229 = 15.036 which equals a leaner AFR. So regardless of the table description of "multiplier", if i put a number larger than 1.00 in there, thats going to equal more fuel right?Originally Posted by redhardsupra

All I can say is 'whatever', a higher number is more fuel. Multipliers generally give 'more', which in this case is fuel.
Either way, that's how it works.
