    ItalianLegacy 3.6R Official Thread

    We all spend so much time and money on our cars things always seem to go wrong most shops make excuses why things wont work or why its doing this or that. What ive learned and can stand by 1000% is that tuning and putting in the proper time to tune under multiple driving conditions and weather conditions makes all the difference. Logging and refinement is key to enjoying your car/investment headache free. This kind of support is hard to find im very happy to have XRT in my corner during this build. Its been very fun but its also far from over. I have many more goodies up my sleeve before this season is over!

    The tuning is going very well and exciting sometimes due to expectations of the owner and being build up to race through all the gears. I am waiting to see the final power and a log showing completely a race from stop to fifth gear and beating up the car to show stability.

     

    There have been extensive logging. Logs upon logs. So far the tuning directory is 200MB of logs. 67 logs taken so far. It has been good research and I am happy to share that with potential tunes to the 3.6 Boosted community. Every step was met with a limit that had to be exposed and removed. Some very subtle and only extensive logging and reviews highlights them.

     

    He is trying to get rid of the mental locks and blocks and only now doing stuff with the car that he couldn't do before for 1 year and in some cases, never did. This sometimes affects logging results, but it is good. It allow the building up of confidence and relationship building.

     

    The 3.6 Boosted tuning is interesting and I leave it for Italian to post his thoughts on the rebirth of his car through XRT. Attached is a small review from him and any reviews he will post here. http://xtremeracingtuning.com/forum/viewtopic.php?f=101&t=657#p1992

     

    So far working with XRT as been extremely fun every little thing he dials in changes the car. The power and transmission feel is dramatic over previous tune. The car feels much more refined the power comes in earlier and just keeps pushing! Since the second day of logging the car to me, and those who know me will testify that i am very sensitive to my car.. the car to me feels like I went out and bought a completely different car. I was nervous at first to beat on the car because of mental blocks i created over time on a bad tune, but lately i sad F-it and i have been driving like ken block stole it and is smooth as can be. no rough idle after spirited driving , no oil burning , no funny ticks from abuse. The car is much more able to put my mods to work now. Its nice to finally feel the difference my investement has made and i am looking forward to one day becoming a tuner myself.

    i haven't posted my most recent updates but here is a few photos so far ecu calibration thanks to the master at xrt and a custom fmic built by the probably the best fabricator on the east coast Brian Cotton of Cottons performance. more coming soon as well as video courtesy of the Flat4Crew.

    Gio, any rasp left? How does she sound above 4K RPM?

     

    Looks like your current setup is very similar to mine.

    Are the o2 sensors wired upstream, inline or downstream of the cats?

    Did you go with 100 or 200-cell metal or ceramic cores?

    zero rasp bro its the high flow vibrant obd2 cats not sure exactly the specs off hand. its much deeper now and so so smooth

    Giovanni...please clarify for me.

     

    Did they do a baseline with OE TB first or is that dyno sheet from your previous tune before the new motor?

     

    EDIT: Okay, I see it says Headers. I assume run 2 is after you added headers. Is it safe to assume that the boomba TB made all that difference? Is that what ECS said? I see boost increased. I suppose they were able to do that because they had more airflow through the TB?

    yes safe to assume that plus higher compression made that difference

    I know dude. I've discussed this with AMR and they'd need the car in the shop to fabricate a Y for it. They'd use the same basic components, but the design would need to be slightly different from 3.6R to 3.6R. Few reasons behind this, I'll outline a bit (what I know) below. Yes, this would be ideal, I know. With the revisions we've done at AMR we learned a few things that could make creating a PnP design tricky.

     

    1. The header runner flanges are angled a bit different depending on if the header spacers are used or not to clear the FSB

     

    2. Stock cats will start to fail (its just a question of time) with the headers installed. Exhaust flow and EGTs (especially without a tune) are too high for them to take and they start to collapse, substrate separates from the housing walls. Symptoms: initially some bogging down, sluggish performance, eventually overheating front substrate surface, back-pressure spikes, random mis-fires, random knock.

     

    3. The solution to 2 is either to go a. catless or b. replace OEM cats with larger ID metal core (higher temp tolerating) units. Catless is easier and cheaper, nets a slight performance gain, but calls for a retune (to realize it and to run safe), but results in a RASP >5K RPM that doesn't sound good at all.

     

    Catless: Exhaust fume smell is minimal (potentially thanks to the tune).

    Using baffled resonators in place of the cats causes pinging within the y-pipe and doesn't eliminate the rasp, using perforated straight through resonators doesn't eliminate the rasp either but eliminates the pinging.

     

    Catted: Using 100 cell race/metal cats only partially eliminates the rasp.

    Only 200 and 200+ cell cats eliminate (or rather muffle) the rasp enough to make it livable, streetable.

     

    4. With the y-pipe design figured out (2.5" ID piping throughout, 2x 2.5" 200-cell metal cats), the location and way it mates to the catback is also different from car to car. All depends on what exhaust we're running (stock 3.6R CBE, modified LGT CBEs in either 2.5" ID, 3" IDs, resonated, non-resonated, flanged or not). Depending on the CBE, the inlet can be offset by as much as an 1-1.5" making coming up with a PnP y-pipe tricky.

    I ran that idea by AMR, but because of above they didn't feel it would be viable for them. Give them a call and if enough of us contact them about the header/y-pipe or just y-pipes, maybe they'll jig something up.

    bro have them duplicate it ill worry about any changes that need to be made... please!
