I'm using the basic accel enrichment with 60% tps, 40% map. pretty much that mix because that was default. i think i'm pretty close on my values.

on seq, i'm still running wasted only. question i have, is that the enrichment bins are an absolute millisec amount. when i swap to a cam sync and run full seq, will there be any adjustments in the code for half the amount of squirts and larger required notional amount?

to have same enrichment in seq, do the amounts need to be doubled? if so, perhaps an adjustment should be in the code for any reason that cam does not sync or whatever?

Because ReqFuel only multiplies the fueling part of pw and not the topen part in which very little fuel is actually injected, you should be ok to double ReqFuel when you go to sequential, provided your topen number is reasonably good.

If you started out selecting cam sync, but just didn't connect the cam sensor, then you wouldn't have to change ReqFuel since the code automatically halves the calculated fuel (without topen) as long as in wasted - which can be forever.

However, the accel number is added to the topen number, so that probably needs to be doubled when you go to sequential. I will think about this and if I can't think of any reasons not to, I will double/ half that according to wasted/ sequential in the next code version.

Thanks Al - that's what I was trying to confirm.

Interestingly, at first, I tried to have no cam sync but could not get it to work. I can't recall the details of what wouldn't work, but I don't think it even recognized cranking. I had to configure for an expected cam sync (which never comes) and it worked fine.
