Tradewind Posted August 28, 2015 Share Posted August 28, 2015 Check clearance around all point of exhaust from front to back and make sure there is no stress or excess pulling at any mount points. It is an installation issue and I experienced it myself several times when I first developed the product. It not the headers themselves, it's how the entire system is fitted. Inspection and small adjustments will eliminate the rattle permanently Link to comment Share on other sites More sharing options...
Perscitus Posted August 31, 2015 Share Posted August 31, 2015 Check clearance around all point of exhaust from front to back and make sure there is no stress or excess pulling at any mount points. It is an installation issue and I experienced it myself several times when I first developed the product. It not the headers themselves, it's how the entire system is fitted. Inspection and small adjustments will eliminate the rattle permanentlyThe low RPM rattle issue was fixed on mine this past Saturday. In my case it turned out to be a loose clamp on the mid pipe not too far upstream of the rear axle and diff. It must have vibrated loose over time or was not torqued down well enough the last time the exhaust was off the car. While here, we inspected the entire exhaust like Tim suggests and found one other 'minor' issue. One of the Bank 2 exhaust port pins was pulled out and never threaded back in by the shop that had the headers off most recently. You can see it in the attached pics, the pin all the way over to the left... compare it to any to the right. We locked it with another nut and fed it back into the block. Re-checked all points from exhaust ports to the muffler tips out back. Tightened all bolts, nuts, etc. And did a smoke test to check for leaks. None found. She's as good as new, no rattles, no strange noises 800 to 6.4K RPM Link to comment Share on other sites More sharing options...

NavigatorsLegacy Posted August 31, 2015 Share Posted August 31, 2015 Ok i feel better that it's not me. Mines 1800-3500 I feel I should go hang out with the Honda crew. LOL...that is how I feel... like a tin can or oil can exhaust ricer when the noise is reverberating..... Link to comment Share on other sites More sharing options...

It is no different even on my own car - the system must be fault free to be rattle free. Impressed! Link to comment Share on other sites More sharing options...
Perscitus Posted September 5, 2015 Share Posted September 5, 2015 Quick update on XRT (Xtreme Racing Tuning) e-tune progress. We are on the 4th, 5th revision now and the car runs better than ever! As smooth and linear as she was in stock form with less than 100 miles on the ODO, but of course far far stronger. Very crisp, quick throttle response all around Great low and mid RPM torque and power delivery in any gear Strong high RPM and WOT pulls (she pulls hard well above 6K RPM) Butter smooth idle Drastically better 5EAT behavior (gear selection, holding, engine braking, shifts in auto and manual mode) Improved sensor readings and ranges (IAM, A/F Learn and Correct, MAF voltage vs g/sec scaling: happy engine, happy ECU) Further refined engine sound (likely as a result of AVCS, base and max knock additive and cruise timing table changes) The tune has rounded out all the mechanical mods and even stabilized Bank1 and Bank2 AFRs, especially at idle and under CL driving... exactly where I need and want them to match. Hats off to Ed for his work! We are almost done I bet, just refining at this point. Link to comment Share on other sites More sharing options...

I'm using 89 tune now using EcuTek(278hp/276lb) with the headers installed and seen fuel consumption take a hit. Still make long road trips from Toronto to Chicago every year, so I'm interested if your changes and it effect on your economy.

Perscitus Posted September 8, 2015 Share Posted September 8, 2015 Hey JT_36R. Thus far its fairly consistent, I'm averaging 23mpg in mixed (mostly city) driving. All highway I typically see 29mpg now. Keep in mind we are still working through the revisions and I'm flashing, resetting my ECU every couple of days... plus not driving it each day. So with each revision the ECU has a. limited time to re-learn (enough for the tune, perhaps not enough for stable MPG stats) b. is learning as the MPG stats build up (which I bet isn't helping them stay high).

nadracer Posted September 13, 2015 Share Posted September 13, 2015 Same here. I haven't been driving mine much. I take the train a lot or need drive my wife's 2015 Forester Touring; great car btw. The new 2.5/CVT are mated well. Just went I thought the tune was over, Edward contacted me with some rapid fire updates. It was like he read my mind solving an irking issue I was having with power delivery at low rpm between 1400-2000. In 4-5 gear there was some power loss too. Much of that is solved and then of course more timing and ignition on 92 octane. Still logging to refine the car if I can just get to actually have time drive it. Seriously Edward needs a standing ovation Hey JT_36R. Thus far its fairly consistent, I'm averaging 23mpg in mixed (mostly city) driving. All highway I typically see 29mpg now.

ananto Posted September 17, 2015 Share Posted September 17, 2015 Are there any aftermarket fuel injectors for the 3.6r? I have been looking for such a long time... \ Link to comment Share on other sites More sharing options...
Perscitus Posted September 17, 2015 Share Posted September 17, 2015 (edited) Yup, we talked about them at some point. Mucho dinero. I will try to find the link. Update: it was actually the set of plasma coil packs for the 3.0R and 3.6R. http://legacygt.com/forums/showpost.php?p=5125195&postcount=733 Coming back to injectors, Supercharged 3.6Rs need bigger injectors, I believe they source them from a 2008+ STI. They fit without issue but require a tune (injector size, PW, DC scaling). For NA, I doubt you need bigger injectors. Ive never seen either my fuel pump or injector DC exceed 70%. Now, some nice aftermarket units might be nice but the stock ones are good enough... most importantly they just need to work properly.

Perscitus Posted September 20, 2015 Share Posted September 20, 2015 Lol, Ed is talking about injectors and coil packs I believe. Headers, exhaust mods, intake chambers and sealed airboxes help this and the 3.0R engine breathe better and make power, tuned. Link to comment Share on other sites More sharing options...

Golferdude1087 Posted September 21, 2015 Share Posted September 21, 2015 (edited) KFC: Perscitus jumped off the ECUTek tune and onto the XRT life. I want to follow him when I have the money but right now I am stuck until I close on my house. And yes I am very jealous of his tune.

KFCConspiracy Posted September 21, 2015 Share Posted September 21, 2015 Do you know if I need to buy a new cable? What's the deal with it? I'm willing to drop the 300 it lists for an etune, but what else do I need to flash? Link to comment Share on other sites More sharing options...
west_minist Posted September 21, 2015 Share Posted September 21, 2015 Any opensource tuning down uses the Tactrix Openport 2.0 cable and free software (Ecuflash & Romraider). Link to comment Share on other sites More sharing options...
