kevindurb Posted August 28, 2015 Share Posted August 28, 2015 Hey guys i've noticed something pretty scary about my 2008 LGT lately... When I'm in S# and i go to WOT when my revs hit ~4k they will very quickly and suddenly drop 1.5-2k... fully stock, original turbo, stage 1 COBB map... any ideas??

08 LGT Posted August 29, 2015 Share Posted August 29, 2015 Try resetting the ECU by disconnecting the battery and then pressing the brake pedal for a few seconds until the brake light goes out, then reconnect it and drive again to see if it still happens.

BrianEarlSpilner Posted August 29, 2015 Share Posted August 29, 2015 I'm guessing you can reset the ecu with your accessport if your on a Cobb map. Or just disconnect the negative cable for a couple minutes. No check engine lights or anything with that? Sounds like a fuel cut or limp mode. Could be over boosting or a battery issue. Here's a thread with some discussion http://legacygt.com/forums/showthread.php/power-cutting-off-4-000-rpmi-151162.html I'd possibly try reflashing maps.

kevindurb Posted August 29, 2015 Author Share Posted August 29, 2015 Ya I'll try resetting and re flashing, the weird part is if I'm not trying to push my car I can easily accelerate past 4k and I've not throwing any codes... Link to comment Share on other sites More sharing options...
