- Troubleshooting ECU drivers and the ISC - GalantVR4. org
I'll test the ISC tomorrow to confirm it's bad, but suffice it to say something bad happened and completely fried the ISC driver The ECU seemed fine up until recently, when I installed the WB I mentioned this to Thomas, who seemed to think the WB install couldn't have caused the issue That was a relief
- Lets talk FIAV and ISC block off plates! - GalantVR4. org
The ISC did just fine, though as stated already - took a few more cranks and sometimes a second of throttle to get it idling normally Btw, 3 out of 4 adjusters were easy as pie to adjust down the runt of the litter was a B*tch! Blow torch and all it took like an hour and a half to get it all of the way down
- What throttle body for GVR4? - GalantVR4. org
Yes newbie question here What other throttle body will mate to GVR4 I am looking to get one locally to remove the isc and plug the coolant line Would N T throttle work ok? or not because of the TB elbow? detail list would be greatly appreciated
- Setting BISS and ISC Range - GalantVR4. org
You want the ISC in the middle of it's range, while adjusting the BISS for optimal setting (Our idle should be 800 RPMs) But what exactly is the middle of it's range? If you log it, I think it goes anywhere from 0-100+ Does anybody have hard evidence on where it should properly be set @ idle with a logger using MMCD?
- ecmlink v3 1g idle settings question? - GalantVR4. org
I have 280* cams, and with the ISC set to about 30 steps at warm idle, I can reach in through the window and start the car even at 15-20*F outside Throwing the deadtime and MAF readings way out from a base number, just to achieve what looks good on the screen, probably isn't going to make the car run better right
- ISC open too much during idle - galantvr4. org
Hey guys, I have been having trouble getting a decent idle recently I have been running a few months with the ISC unplugged while I try to figure out the problem Stock 91 VR-4, using TMO to datalog The ISC stays around 76 or 77 steps during normal idle, while the engine is around 1500 rpm
- Ecmlink Idle issues - help please. - UPDATE - GalantVR4. org
Let me know if this sounds right or wrong I have tested resistance to the ISC coils and they all check out okay The TPS sweeps cleanly from 0 63 to 5 00v and it looks stable in the logs The MAF was working fine prior to the valve cover change, I removed it with the coupler and air filter attached and sat it on the bench until re-install
- Test ECU Injector Drivers - GalantVR4. org
I had a 2nd ISC go out this weekend and I'm unsure how to determine if it took out the ECU driver Is there a test I can do on the ECU to determine whether coil pair A and B are still good? The car is idle surging even with the ISC unplugged, so I'm leaning toward the ECU is fried again
