grimmspeed 3 port tuning help

I know there are threads about this but they are so spread out across the pages that I can't follow up with them. So far I've got this:





Both, low gear and high gear correction intervals are set to 0. The tables are set up according to what I've read on the forums, or at least what I managed to get from whatever I read. Is this correct? Or is there something I'm missing here?

yea going all that crazy isn't necessary
set correction intervals to 3
cut the compensations in 1/2 and start tuning
also change TPS added WGDC to 4
instead of 10

the three passive wgdc tables are correct. you zero those out with a 3 port.

i've never seen anyone zero out the reactive wgdc tables before in the partial throttle area (the columns from 28.8% to 69.2% TPS) before. this means you will be running pure wastegate with no input from the 3-port. should be fine but the car is going to feel sluggish in part throttle.

you have posted the 'target boost error correction' table (direct boost) as well as the 'reactive solenoid turbo boost error correction' (load boost) table. if you are tuning this using direct boost, just ignore everything in that load boost section. they are the same table but just scaled differently.

baka is correct (of course), set your correction interval.

also i wouldn't zero out the boost error correction table (especially in the higher positive numbers). the only thing this might do is save your motor in the even of severe overboost.
