I have TSI kit. It comes with black box (MAP hack). You have to tap in in to OEM MAP for voltage, groud and signal in/out.
I suspect it doesnt work in my car. Connected or disconnected - no changes, harsh/low idle, stalls when slowing down after run.
I saw there is a thing calld Missing Link and Chack valve thing.
Post #14 - follow link for the Check valve unit:

See attachmet.
Cant the Check Valve thing replace TSI map hack?
Can you replace black box with something else?

Is this what tsi black box does? Its intersepting and changing voltage #'s on that (I dont know name if it, I thought it was MAF, so its MAP?) sensor.
BTW: Plug for the sensor I'm talking about, located on the drivers side off the TB, little below vacuum lines?
Can I substitute it with a series of check valves as attachment shows in the main post?

My idle is fine when i strat/restart engine.
At start idle will be fine, with this idle car will drive very well under boost or no boost, WOT or partial throttle.
Then on neutral will rise it will rise to about 1500-2000 after 1-2 boosted runs. Then with this idle I cant take off, engine coughs and then shuts down.
Have you have same thing?
May be black box - 2 peoplewith new kits?
