Qckslvr Posted June 19, 2013 Share Posted June 19, 2013 All I did was copy the factory ROM to the laptop using ECUFlash, no tuning, or any funny business. When I get in the car to drive today, the RPMs are sluggish; a quick jab of the throttle produces a slow rise in RPM. I noticed it the most when I went to rev-match... Any ideas?

What would I be looking for? Take an LV and post the screenshot up here. Enable DTC reader too. It will help determine any "funny business" Link to comment Share on other sites More sharing options...
ssbtech Posted June 20, 2013 Share Posted June 20, 2013 Any chance you reset the ECU? Link to comment Share on other sites More sharing options...

BlazeRex Posted June 20, 2013 Share Posted June 20, 2013 Probably reset the ECU. Give it a couple days. Link to comment Share on other sites More sharing options...
rtbrjason Posted June 20, 2013 Share Posted June 20, 2013 Pulling the rom in newer canbus cars does reset the ECU. Afterwards, you need to let it idle for 5ish minutes without touching the accelerator, or you will have rpm hunting going on for a day or 2..

So at this point, assuming this is what is occuring, do i now let it idle for a while, or do i "reset" it again, and then let it idle, or....?

Spec B Posted June 20, 2013 Share Posted June 20, 2013 Just reset the ecu while the car is fully warmed up. Restart and let it idle for 2-3 min, then do a few part throttle runs. What happens is your IAM drops after a reset - ECU needs to make sure there is no knock before giving you full timing advance. Easiest way to do this on my car is 40% throttle runs.

fahr_side Posted June 22, 2013 Share Posted June 22, 2013 RR Logger can reset the ECU, as can Learning View. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.
