The map you posted is TPS vs RPM, not relevant to the thread. And looking at that map without knowing any compensations applied...the map is meaningless unless you can verify there are no other compensations.

And all load sites should be tuned on the dyno. That applies for fuel and ignition, but especially ignition as you can see and monitor any torque increases from timing changes

only air temp compensations on timing just for safety...

If you have a query about your setup, I think it more appropriate to start a new thread, as yours is not relevant to this thread.
But you're timing everywhere looks very low.

Just a quick update,
I've managed to write my MAP as load based map using log files from the tps map, to my surprise it worked almost perfectly just needed a bit of a tweek at idle.
One question though does the start fuel map still take its reference from column 1 row 1? As my start fueling seems to have gone lean but I made sure the figures in that cell stayed the same
Cheers

on cranking it will be pretty much atmospheric, so will be that cell instead on MAP, not 0%TPS.

Now got it to run through my ipad or iPhone so when the oxygen o car stereo arrive I can have the real time info on the dash

Is that the DTA software running on the ipad ? How is it communicating ?

It's running on my netbook using an adhoc network and Remote Desktop software so the net book can go in the boot and I can use the touch screen ability of the ipad, less wires in the cabin and more mounting options for tuning on the fly, the new knobs box from Martin is a great little addition too

How did you find running with MAP as load over TPS? What are the benefits?

I'm running TPS but as it's a supercharged engine which was run from MAP on the factory ECU I'm thinking of switching.
