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
ISC replacement options. - GalantVR4. org Seems the ISC driver kursploded from a short, which explains why it was unplugged The OEM replacement seems to be big money Has anyone had any luck with the one offered by Rock Auto? Are there better options I'm not finding? I have yet to OHM mine out but with the motor unplugged and the damage I'd say there's a good chance it's bad
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 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
isc not working - GalantVR4. org So replaced the ISC after my last ecu blew a driver, I replaced the ecu and rewired the pump as some of you may remember, I have a bad idle surge now, and I adjusted the biss all the way in and still idles and fluctuates around 12-1600 rpms, The ISC I pulled out to see if it'd move with the key
What is Proper ISC Voltage and where to check? - galantvr4. org Have you pulled your ISC and make sure it moved like in the youtube video I keep linking on Tuners? After bootim the ECU homes the ISC by stepping it all the way out, then back to 0, before moving to the position for starting the car Remember that idle surge is caused generally caused by too much air bypassing the closed throttle plate
