[petert 591]

Sure. Standard or modified engine?

my map looks like this

What is the difference between TPS 100 and TPS 160? I don't understand the units.

95=0%TPS , 100=5%TPS and 160=95%TPS

 megasquirt works with a positioned range from 1 to 255 , depending on the range of the TPS sensors , you are calculating the values

[petert 591]

Ignition, TPS 100:

1000 should also be 12 deg

800 should be 20 deg, so if the idle speed starts to stumble at 0% throttle (idle), the increase to 20 deg will bump the revs up, hopefully preventing it from stalling.

 

Can you add a 500 axis? Remove the negative values, it should never go under 10 degrees. Otherwise looks fine. You'll find 26 at WOT may even be too much. Try 25 from 3000 onwards at TPS 160.

I will check with 25 over 3000rpm

the negative values are adjusted due to the easy retreat of low rpm and mid throttle , easily pulls in medium rpm
