Most sequentials come with a gear display to hook up to the pot ? Which would be active at all times.

Dont think they're too expensive, so if there is a pot they should be able to work.

I have posted here before about the abrupt on/off nature of fuel cutoff on overrun. I have just found that a technique to overcome this used by Honda (and possibly others) is to incorporate a 0.5 second delay before cutoff is activated. Would it be possible to add a configurable delay parameter to the fuel cutoff on overrun feature?

As a minor point on this feature, when cutoff is activated, the system still logs fuel utilisation according to the values set in the main fuelling map - it doesn't recognise that fuel cutoff is active.

Thanks, Richard

Not on the current hardware, we don't have any timers left to implement that with.
It's something I'll not for the new hardware.

I use the fuel cut on overun and it is barley perceptible. Just needs setting right.

Mine is also very smooth transition from normal running into fuel cut and back on again mine is set at 1800rpm i think it may be down to how rich or lean you are at specific rpm that it comes on or goes off.


Im at 16 afr on most low load sites so i can try get good mpg when in following trafic :D

Is there a possibility that some extra data could be added to the CAN stream, particularly the status of fuel pump and fan it would be handy for people wanting to use a PDM. launch control, traction, pit limiter, map 1/2 could be useful to have too.

That's all fairly easy to do. I have most of that already on the dash stream, so adding it to the general stream is no problem.
I'm planning some firmware updates this month, so will add those in.

I have notice that when a car stays a long time at idle the wideband goes richer, i suppose its because of hot air that make fuel mixer richer...

so is it possible to have a table like idle base advance map but for fuel only at idle with water or air temp user selectable se we can map fuel separately for idle when we dont use idle valve ??

sire the air temp somewhere less affected by heat soak...or closed loop.

closed loop does it just fine. heat soak on the air temp sensor can squw things up but closed loop sorts it out any way in my Experience
