Kinda what I was thinking as well. Some people use a pot, from what I understand. I think the hall sensors would be a little better.

 

as far as a motor shield i havent seen anything i was comfortable throwing at this motor, looking at the stock controller its driven by 6 mosfets, one for each lead. all commercially available shields seem designed for small hobby motors and usually only 1 or 2 pwm outputs. the stock oem can chip is using 3 pwm leads to drive it

 

eh not one for each lead that was an oversight

 

i run these turbo on my lsvtec the past year.

i wasn't able to run the vgt corectly.

my wastegate was opening at the same time as the vanes open.that makes the boost to fall at around 4000-4500 rpm.maybe,the vanes was opening too quickly

i try with the vanes closed.the boost start from 3300 rpm and 13 psi at 3800.

with the vanes completely open, the boost start at 5200 rpm and 13 psi at 6000.

the result with the vanes open was 356 whp at 13 psi with an 1.8 lsvtec.

for the peaple that ask if we need a wastegate,i think you have your respond.we definitely need one.

for this summer i want to control the vgt, the gain was about 60whp at 4500rpm.

Did someone test civic tsi controleur?

maybe its the solution for my problem

 

I'm working with a company that engineer parts to get a plug and play controller made. Full electronic control that is stand alone and will work with any vehicle is the goal. I'll let you guys know when a test module is complete and running.

 

i simple wastegate actuator and a boost controler is all u guys really need.
with a few mods to the he351 actuator u can make a mechanical actuator that works on boost presure.
grantd its not as nice as an electronically controlled unit. but its cheap simpl and effective

 

yes that is a well known fact and addressed near the beginning of the thread. no to mention the many youtube videos covering it.

 

as far as I have found no one has attempted to. and I have talked to civic briefly on the subject back in December and he has shelved the project for now.

as far as your mechanical control yea it sounds like your wgate was opening too quick, perhaps you should use a larger one to move the vanes slower.

 

will it be cheaper than the $500 fleeceperformance controller? its $400 without the exhaust brake option, funny how a few lines of code and a toggle switch jack up the price a hundred bucks.

 

don't know if this has been said, but if your just looking for tune ability, why not do the wg to control it then use a electronic boost solenoid that is controlled by Megasquirt. you could then use many sensor inputs to control the solenoid automatically with say egt's, boost, and rpm! this is the option I am leaning towards.
