So I have been struggling to get my Galant VR4 to run well since I reinstalled the motor after rebuilding it. GST with PSI's build & restoration of 1813 | Galant VR-4 > General VR4 Discussions | GalantVR-4.org Mitsubishi Galant VR4 Forum Problems I am currently having:
- Car overheats, even with both cooling fans running. In short, I do not believe this is because of the cooling system, nor the fans. I think this is related to how crappy the engine is running. Cooling Issue (updated). Need help, pics inside. | Galant VR-4 > Technical Discussions | GalantVR-4.org Mitsubishi Galant VR4 Forum
- Car will not start again after it gets hot. It cranks, but wont event try to fire.
-Car has a high idle, and will not go into closed loop. It runs pretty smooth, but the throttle response is garbage.
I found out today after logging a bit with my DSMlink that my coolant temp sensor is not working at all. I reads a constant 9 degrees Fahrenheit. This would explain one of the reasons why the car won't go into closed loop. Additionally, the timing seems to be way to advanced at idle. I'm just getting into what expected values should be, and what to look for while logging. If I'm missing something blatantly obvious, It's because all this is pretty new to me. I'm sure there are lots of problems glaring at me, I'm just too much of a DSMlink noob to realize it /ubbthreads/images/graemlins/dunno.gif Could some of you guys with more ECMink experience here take a look at this log and tell me what you see?
***At 105.5 seconds on the log I grounded the timing connector using the link feature. The car subsequently started running like crap, and eventually died. It wouldn't restart afterwards. So, just as a heads up, that's why there is the durastic change in the log at that time.
Car info:
Everything is pretty much stock...
Stock motor
Stock 450cc injectors
2G MAF (I switched this on Link)
Walbro 255 with fuel pressure set @ 37 PSI
Thanks!
