Hi there guys.

Im wanting to control my boost using the stock ecu on my 30R with 44mm Tial external to @35psi.
I have wired in a Mac valve N/Closed to the top of the wastegate, the same as when using my ProfecB. Everything is working okish as long as I dont want to boost too high.

I basically just want to run on duty cycle only and not worry about error correction etc at the moment. I thought that increasing the Load Offset to allow for running up to 400load would let me just set the duty cycles as i want.

I set the Load Offset to 200 and increased all the Boost Desired Engine load tables to 159.4, BUT the ecu keeps reducing WGDC as soon as the load goes over 220-240 ish. When I first hit into boost the load gets to 300 then gets massively corrected down to 220 then the WGDC goes higher again and allows the load to pick up again then gets dropped again.

Also at idle the WDC is like 78% is that normal????

My vehicle is a Mitsi Airtrek Turbo 83540008 rom

Could someone check thru the def below and make sure the address for load offset is correct.

Thanks in advance!!

If your correction table is zeroed out it should run on base wastegate duty cycle.

 

On the log above it isnt zeroed out, so I did a couple of runs just now with it zeroed out and it made no difference at all

 

Run on the gate, remove the EBC, and then tell us what happens. Logs would be nice!

 

i run a 30r with a 38mm tial. I have a prodrive BCS and run mrfred's direct boost control with no issues. my WGDC is about ~40% which gives 27 psi.

 

Wastegate spring is 18psi and is running fine on that as Im doing that while I get the control sorted.

I know that it should work fine hence the reason that I think my definition is wrong somewhere and not allowing me the control that I should have.
