Ivan Posted September 26, 2012 Report Share Posted September 26, 2012 Just a little background on the car, 95 Mustang GT 302 with Trickflow track heat top end and Procharger D1SC, 50# Bosch injectors, matching Pro M maf, 340 lph fuel pump, tuned with Moates QH. This was pretty much a ground up build using new everything minus the low mile S/C. I put it all together and got an email tune from dirtydirtyracing. Car started and ran ok but had a choppy throttle pull, it would break up and then accelerate like a beast on the top end. I had a buddy look at the tune while we cruised and said that one of my o2 sensors wasn't reading right. The car sat for a while and this past weekend I changed out the sensors and switched my plugs from a one step colder autolite copper gapped at .034 to a 1 step colder non projected NGK plug gapped at .023 since that's what Bob Kurgan recommended for my app. I also noticed that one of my wire boots wasn't seated properly on the spark plugs and made sure they all clicked once I put them back on. Bob is tuning my car in November but until then I'm trying to sort out any problems that may arise. Well I went around the block a couple of times and noticed that the throttle response was a lot smoother but it was running really lean according to my A/F gauge and it didn't seem to have as much power. Then I started to see a lot of smoke coming from the engine bay, I pulled over, made sure the car wasn't on fire and then I opened the hood to find the powder coating on the EGR smoking/melting. So I'm guessing the headers got hot enough to melt the p/c, the problem is I can't figure out why and it doesn't help that I have no idea how to use Binary Editor other than to write a tune to QH. Any ideas? Link to comment Share on other sites More sharing options...
itsblown93 Posted November 8, 2012 Report Share Posted November 8, 2012 are you using a wideband or just a A/F guage? get a wideband so its more accurate. Link to comment Share on other sites More sharing options...
330CubeGt Posted November 8, 2012 Report Share Posted November 8, 2012 Any cars going to run alot leaner with these cold temps, hell I know mine is. You might want to fatten it up for the winter time...Heads up and ass kickin! Using Tapatalk 2 Link to comment Share on other sites More sharing options...
revhead347 Posted November 10, 2012 Report Share Posted November 10, 2012 Usually the headers get real hot if it's running way to rich, not too lean.Kurt Link to comment Share on other sites More sharing options...
