ok my mods are turboback,intake,uicp,licp,MBC,flash and i get codes from OBD and in the past it used to be only exhaust codes recently this came up: DTC P0234: Turbocharger Wastegate System Malfunction my boost is fine my mbc is set at 22 pounds and it stays there, it used to boost spike during winter time!!! or do i need a new MBC?!! thanks i appreciate it! and i used the OBD scanner cleared the code came back after 100 miles. car runs fine i ran a 12.5409 with the code on my car.

 

Do you have the electrical connection still connected to the factory BCS. It needs to be the simply cap off the ports

 

the solenoid thing? not sure but how bad is this code?

 

The stock BCS needs to be plugged in.

Be sure your boost limits are set high enough so that you are not exceeding the load limit in the ECU.

 

the boost stays at 22 (where it should be) so when i open my hood where can i find the BCS?

 

In front of the battery usually under the intake box. Some aftermarket intakes require you to tweak its position. Its gold with 2 ports and an electrical connection.

 

Thank you^^

 

hmmm cant seem to find it i have a small batt kit and diffrent uipc cant find it anyone got pics?

 

I cannot fine it because it is not there i remember the guy threw it away when my clutch was done!!!!!

 

i do not have it

 

Likely that is your issue then man. Do you see the plug just dangling there somewhere?? I don't believe any harm will come to the car being that it just stays capped off anyways but not having the connector plugged in will surely **** off the ECU

PM russellm from mitsubishiparts.net It can't cost that much for a new one

 

no we do not i remember the guy that did my clutch threw it away, i have a hard time findint it on mitsuparts also

 

here it is http://www.lancershop.com/customer/p...8&cat=4&page=1

even when we had the solenoid on the car last year it was unplugged(mbc install) never threw a Code. what if it is not the BCS

 

Thats not what the EVO piece actually looks like but if he did throw away your BCS like I said the electrical plug will still be in there dangling off the main harness. Just get a new one and plug it back in.

I know that even when going MBC/EBC the ECU still needs to see that electrical connection to keep happy and code free

 

Not doubting you man but I'm positive the ECU will throw a code if the stock BCS is unplugged.

If this is not the issue you'll be looking to the tune as Scott from TTP mentioned. You'll need to look to the Boost Limit, and other boost related mapping to ensure they are set high enough
