Booston Posted April 13, 2020 Report Share Posted April 13, 2020 Is there a way to have a different duty cycle in a particular gear at each rpm point ? the global gear correction is not sufficient for my needs Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted April 13, 2020 Report Share Posted April 13, 2020 Have you thought about making the boost target table gear based? Booston 1 Quote Link to comment Share on other sites More sharing options...
Booston Posted April 13, 2020 Author Report Share Posted April 13, 2020 6 boost tables ? Hmmm I don’t know how to create a table for each gear . Possible ? Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted April 13, 2020 Report Share Posted April 13, 2020 can do one table, gear on one axis and rpm on the other Quote Link to comment Share on other sites More sharing options...
Booston Posted April 13, 2020 Author Report Share Posted April 13, 2020 Cheers Brad I get that , but wouldn’t I then loose DC based by TPS / RPM ? Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted April 13, 2020 Report Share Posted April 13, 2020 The closed loop system is fantastic. WG DC table(rpm x target boost). target boost table(rpm x gear) or (rpm x tps) Then you can even have gear/iat/ect adjustment tables for both target and WG DC tables. Theres really a variety of ways you can set it up to suit your needs. Quote Link to comment Share on other sites More sharing options...
Davidv Posted April 13, 2020 Report Share Posted April 13, 2020 I've been thinking about this lately, essentially you're trying to build maximum horsepower to your cars/wheels traction curve. So you dont necessarily want more boost in 3rd gear at the same speed as second, you want the same amount of horsepower at that given speed. So I thought controlling the wastegate based on speed vs injector duty cycle would be a decent simulation of horsepower level. If you dont have enough boost in gear X to get to 30% DC on the injectors at 55kph. Here, have some more haha. (and vice versa) Quote Link to comment Share on other sites More sharing options...
Booston Posted April 14, 2020 Author Report Share Posted April 14, 2020 Hmmmmm perhaps torque management can be used ? its my gearbox they have a very weak 4th gear over all other gears and will be broken if torque is as high as available so I thought to reduce boost at peak torque in that gear but now maybe TM is for this ?

Adamw Posted April 14, 2020 Report Share Posted April 14, 2020 You can have three completely seperate boost tables, or 2 interpolated. So for instance you could have one table that is active for 1st-3rd gears, one for 4th and 1 for 5th. If only 4th gear is the concern then you could just switch to a second boost table whenever 4th gear is engaged which has lower DC or boost target in it. If you want different boost in each gear, then another option is to have two boost tables in interpolate mode. One high boost table, one lower boost. Then use gear position to blend between those two tables. Booston 1 Quote Link to comment Share on other sites More sharing options...
Booston Posted April 14, 2020 Author Report Share Posted April 14, 2020 Awesome Adam thanks. It takes away switchable boost levels but hey Quote Link to comment Share on other sites More sharing options...
