I'd suggest 1,5,20,40 may be a problem on the Rover if you're using the standard throttle position sensor - it's quite noisy on mine (by one LSB), and always triggers the accel enrichment.
I use 3,7,20,40 instead.
I am having a head ache over this as well
I have just come back from a holidy in Cornwall in the Mini and encountered little problems other than the engine cutting out in the second lane on the up side of the Avon bridge crossing on the M5, lol, thats another story. Whit this did allow me to do is watch what was going on, when the screen wasnt playing up, again, another story.
It was clear that the suggested 1 5 20 40 bins were causing AE when the throttle was almost stationary. The Mini is not the smoothest of rides and every small bump caused AE unnecisaraly. Having read this topic before we left, I altered the bins to that that you suggested and the problem dissapeared. I do however still need to sort out the transient fuel amounts.
Slow acceleration is almost perfect, only issue with sudden WOT situations where a massive lean period causing the engine to cut and recover. Im finding it difficult to tune as i really dont know which bit im altering.
So, in AE for dummies, can some one help me understand, its a real killer on the drag strip and its showing on times.
OK so far i understand the acc bins as the rate of acceleration, small number gentel acceleration, large numbers hard acceleration. I also mildly understand the acc amount as being the extra, added ontop PW?? to that of the base PW??
Im thinking the acceleration duration is the time the 'lean' peariod lasts??
Now after messing about, the larger duration time i use, the larger the rich dip is on gentel acceleration, the better it gets on hard acceleration, so the duration and amount need to be tuned together.
Am i correct in thinking as I increase the duration to get the hard acc sorted, i need to reduce the lower acc amount to stop the rich dip.
Or do i just increase the hard acc amounts, in which case where dose the duration fit in
the longer i think about it the more i'll understand it
, i now have a week to play with it without relying on the car to get us home
