Can you run a Map psark map on alphaN
As the title really.
I am running MS1 extra code and alpha N but feel my spark map is crap to say the least. I have asked a couple of members on here ( can't remeber
who) for a look at theirs ( vauxhall xe with gsxr bodies and wasted spark0 but I have lost the U2U's after having a clean out.
So i have found a few maps where the spark map is rpm versus M.A.P and wondered if it would be worth trying them out (If it is even possible)
A quick answer would be good as it is a cracking day up here for a blat.
If it looks wrong it probably is wrong.

I think it was CairB who modified the code to allow MAP load for the spark and TPS as the fuel load.
So yes it is possible but a RR session will give you the best map.
But then there's the cost involved.

and spending money is against Mr Millars religion which is the church of "tight arse"

With MS2 you can run MAP for load for spark and TPS for load for fuel.
I cannot remember if you can do it with MS1 though.

Not as standard on MSI but you can with CairB's mod.
MSII is more money again

When I changed from MAP set up to Alpha n I used the existing map and changed the load settings to correspond with my TPS range.
This gave a starting point to enable me to data-log it and see where i was running on the MAP.Full and minimum load sites stay the same and the in
between rows can be adjusted to suit.

I'm not sure how you could do this, since MAP and TPS are not interchangeable. A map using TPS as the load parameter has a very different
overall shape to one using manifold vacuum.

I had read it this way
looking at a datalog you could see what a steady Map signal was at a certain tps point then set that tps point into the map vsus rpm tabel at said
point.

Thats basically what i did ,I knew the full load and idle points as they are the same for map or TPS.The in between points can then be guessed at and
adjusted with the help of data-logs or you could just start with a 2d map and work from that.
This would not work for fueling however as the map is totally different for that as its governed by the volumetric efficiency of the engine and is
very different when measured by load or throttle position.
However fueling is easy to get somewhere near right on the road using a wide band, but to get timing spot on ideally needs a rolling road as it is not
possible to tell the difference in small amounts of power variation or spread of power by feel alone although I just tweaked mine until i got it to
drive smoothly with good power delivery.
