    1G 90 No voltage to Idle Position Switch (IPS)

    Okay, sorry for the delay, but I have updates!Case is 90, board is 90. Definitely had original caps leak out, but it looks properly remanned, cleaned up, traces peeled back, etc. Dated 2003 on reman. Replacement caps still test good.On a whim I threw it back in there, but left it dangling...

    1G 90 No voltage to Idle Position Switch (IPS)

    Ahh! Good tip, I can check the MAF reset for voltage when I get home, but no, I have no idea how to identify the PCB as 90 or not.

    1G 90 No voltage to Idle Position Switch (IPS)

    Let me try to clarify by answering you in reverse order.It does now have multiple ground straps from the throttle body, as the factory strap was missing when acquired. Didn't help my hesitation off idle symptoms.So next I go to check for voltage coming to the IPS. Unplugged the IPS wire from...

    1G 90 No voltage to Idle Position Switch (IPS)

    Key on, engine off, I have about a tenth of a volt at the IPS, with it unplugged. Confirmed no short between IPS and ECU. Also, key off, the IPS wire has continuity to ground, but only so long as the TPS is plugged in, throttle closed. It loses this continuity if you open the throttle about...

    Resolved '90 Talon TSI weird ECU pinout?? No connection to diagport, no wire at all for pin 2

    Harness is supplying 5v, TPS sending back a clean signal. I had my dad hook up his oscilloscope, while I heated the TPS with a heat gun and it looks absolutely perfect. Discovered an intermittent idle position switch, and replaced it. But my main problem persists. I did not do a road test to see...

    Resolved '90 Talon TSI weird ECU pinout?? No connection to diagport, no wire at all for pin 2

    Thanks! Switched to a broken old analog meter, but it works enough to watch needle jump, she's working now. Code is 14. f***. Anyone know where to get a 90 TPS?

    Resolved '90 Talon TSI weird ECU pinout?? No connection to diagport, no wire at all for pin 2

    Yep, that's great Steve. This is what I get for just downloading the first pinout and going to town like I know everything. Headed back out there now, we'll see if I can get these issues squared away.

    Resolved '90 Talon TSI weird ECU pinout?? No connection to diagport, no wire at all for pin 2

    Oh my god. Id10t error, I double checked my orientation like 3 times and never realized I was looking at the plug backwards. Empty pin is for ABS. PLEASE DISREGARD MY CONFUSION

    Resolved '90 Talon TSI weird ECU pinout?? No connection to diagport, no wire at all for pin 2

    Hello, title pretty much sums up my situation.Just purchased this mostly stock 90 Talon TSI awd, this is my first turbo car, so it's all a little new to me, but I rebuilt my 4g37 1ga, for what that's worth.Long story short, I've gone down the list confirming everything mechanical. Fixed all...

    1G 4g63 cam gear on 4g37 questions

    People have done a lot more for a lot less. Why does this surprise you on a forum called DSMtuners? The point is to make these things as fast as possible in spite of all logic that tries to convince us otherwise. Sorry I like working on my junk.

    1G 4g63 cam gear on 4g37 questions

    Thanks! That's what I'll do.The point is just to remove a small amount of weight from the engine's rotating components. I've already milled it down, so the width is not an issue.

    1G 4g63 cam gear on 4g37 questions

    Thanks! I found that thread, but must have missed that about the bolt heads.So, I'm more confident I've got my hands on a genuine 4g63 cam gear, but what are others doing about this "between the teeth" issue? I'm assuming most people must not notice. I'm sure the motor still runs decently...

    1G 4g63 cam gear on 4g37 questions

    So, I'm going through my 1.8 and doing a balance shaft delete and decided to do 4g63 cam sprocket, since I had one laying around.The problem is that this sprocket is a half tooth off from stock (see attached). I lined up the old sprocket to TDC and slapped on the new one to find it lined up...
