Use MAP only above 70kpa

Post by arraydude » Mon Nov 23, 2015 6:43 am

A saw in the new version the posibility to set the MINIMUM pressure for speed/density...

So is it possible using the AFM for part throttle and left the MAP for the WOT side of the table ?


How this works????, and a last question, in the changelist i saw the 'ignition retard and fuel add for launch control' but i cant find it

Yes, it is possible!

AFM for part throttle for smoother, more comfortable driving and using especially if the engine is naturally aspirated.
MAP for WOT for spontaneous, more sporty driving and using especially if the engine is boosted.

Especially for supercharged/turbocharged engines and with DBW, this is very good, to reduce jerky Throttle, etc.!

MAF is only present when no boost pressure is there, or if part throttle (depending on where the threshold is set!),
MAP is present when boost pressure is there, or if WOT (depending on where the threshold is set!),

For example, i have this exactly at my supercharged FN2, its a Hybrid Map.

To understand as an example on my Hybrid-Map (AFM-based with MAP-fueltables):
Fuel -> Fuel Table Type -> hook at "AFM enabled"
+ hook at "Use speed/densitiy (MAP) fuel tables"
+ Minimum pressure for speed/density 1,15 Bar:

The lower VTEC-switch-point is on 3200 rpms.
The lowest point where the VTEC-window-pressure is, is set to 1,15 Bar @2000 rpms and 3000 rpms:

So i have fixed the switchover from MAF to MAP also @1,15 Bar.

If i run on part throttle and below 1,15 Bar, i run on MAF.
If i run on WOT below 1,15 Bar, i run on MAF.
If i run on WOT over 1,15 bar, i run on MAP (MAP is better for boosted engines and boost is present from 1,00 Bar manifold-air-pressure upward).

Is your car/engine also supercharged/turbocharged?
I think yes!

Interested in an answer for you second question also. I can't seem to find the "ignition retard and fuel enrichment" that was listed with the latest update. I know it's supposed to be under rev limits, but nothing has changed in my FlashPro Manager.

I believe this is only available on the US Civic SI calibrations.

Is there any way to add an indicator as to whether is ECU is using AFM or MAP fueling? Or we just have to trust that the set switch point is working?

My car is stock and gets better gas mileage on my AFM cal (+/- 1% strim on the highway), but feels like it pulls stronger at WOT on the MAP cal. I am planning to use the AFM for closed loop and MAP fuel tables above 0.85 bar.

There is no way of making an indicator for this. Whatever setting you set tit to is when it will change.

Thanks man for your very complete response, yes my car is turbocharged now , and i'm using this hybrid configuration... Thanks again!

Awesome and complete response R-12914! Thx!
I see that you have TTS Supersport kit, which Im interested to buy. And also saw that you had some problems with injectors, etc
If you can, I would like to ask you few questions about this. Not sure why (probably post limit) I can't send you a pm. If you can, please start a private conversation to hear your thoughts about this kit and how to prevent some problems you learned on.
