Boosting/Electric Problems with the 91 tsi

[driftn1g]

Ok so FINALLY we have another dsm on the road, hes some background of the car, 3.5 maf-t setup, 450s, 190lph, 2600miles, china ebay 16g

Now to the fun part, The car at first would not start due to a bad ecu. We replaced the ECU and it fired right up.. now were stuck with an ignition problem, (hard to explain)
Now picture in your mind sticking the key in the ignition and turning the key to the start point in-return hopefully turning on your car, this is our problem, we do exactly that but when we turn the key to the start point, nothing happens, besides the idiot lights flashing, for it to catch we have to turn it off then to start, repeating this process finally gets the car to turn over.. we replaced the starter 3 times, so we know its not that, its something electrical in the whole ignition system, what that electrical problem is we dont know..?? as far as right now we have to click to wires together to start it...

now on to the boosting problem, the car now idles at 2k, which I think is the ECU again.. anyways the car will start to go into boost, as the needle pushed passed 0psi it hits a flat spot kinda like when a IC pipe blows off.. we think the MAF-T could be wet, also it could be out of tune being its a 3.5"..

Update: were going to throw on a 2g mas and plug to see if that works.. we'll be at shell gas station on brooklyn blvd in the cold

2g mas fixed everything.. still the electrical problem

Check all wires and load test the battery.

does the key just make a click like sound??? my car did that and it was the ignition column thingy... whatever you insert the key into.

yeah!

try that... i was having problems and after that it was perfect. you can always just check the voltage going through it to.

I have the same problem. I think my ignition switch is going out.
