Alternate boost control strategies


This is a post to discuss alternate boost control strategies for the internal boost control. Turboboy750 suggested alternate strategies. Lets discuss and try to come up with a logic flow as well as the I/O requirements of alternate methods.

I think a ramp up rate for where the 100% value was.
PID loop for maintaining boost levels.
Ramp down rate for where the overboost 0% value.

I was taking a shower and was thinking about boost control and wanted to write it down before I forgot.

-Have the ramp up rate have the capability to be a timed reaction associated with Gear Position. Or even RPM per gear.
-Have the ramp down rate have the capability to be associated with drag tool's RPM/Seconds. EXample If RPMs per 1000 climb faster then ....seconds reduce solinode stroking by .......

I have not played with a AMS 1000 but I would think that some of the control stragaties could be "altered" to work with EE/WR software.

Oh make it 237rwhp and 97lbs on E-85 100% stock motor 8lbs of boost. Thanks WIN Racing

i think that time based boost control should be the next step. i am already using the gear based on both my street and race bike and i would certainly like the ability to change it to time based.

Me too. I would not mind traction control by boost as opposed to ignition retardition in my case better also.

Trouble with active boost control and the manifold pressure source is it will spike and drop , like the initial attempt at boost control did,, i think boost control for traction could give the same results , having it just a preset DC on the solenoid gives smooth repeatable boost levels and was fairly simple to impliment at the time

, time based will work good, and i think not to hard to do ?? Justin ??

to see what else can be done with what we have available download the eboost-2 manual, its probably the closest thing to what we have ,
you could preset more complicated boost patterns , ramping in the changes or trailing off at the top end , just depending how much time Justin wants to spend on the refinements

The ramping etc could be possible, not sure about traction control.. Alot is possible, from my perspective if we have a clear definition of how it should work it will make my job easier. I still have a lot of baseline work to do in WRT first before i get to making major revisions to boost fuel but i am committed to continue developing it and possibly extending it for use across other models. Other requests i have had are to have different boost setup based on MS0/MS1 and A/B/C modes allowing preconfigured dial in for different conditions...
