Tuning secondary map

8400rpm Tue Nov 27, 2018 9:07 am

Hi. Kindly advise how to tune secondary map. From my understanding the car is running off the primary map by default.

I would like to tune primary map on tps and secondary on manifold pressure.

Would i need to tune in primary and then copy the map over to secondary?

You can't simply copy them over since the breakpoints will not be the same. One is TPS. One is MAP.

You set them up as you want, control the crossover if you're trying to do alpha-n, and then tune them accordingly.

Sure. Didnt mean copy tps map to pressure.

So if i understand correctly..i need to set the conditions for map switching, lets say at 3000rpm..do this 1st, then tune in primary till 3k and then start tuning in secondary after 3k?

Well it'd be ideal to tune fully on MAP then fully on TPS, and you can then transition any time!
