After finally getting a chance to check out my ecu, it seems the previous owner had a horrible tune or he removed some aftermarket parts and didn't have it retuned before he sold it (I noticed the UICP was threaded for meth or similar).



I was considering upgrading my rom (94170008) to 0015 w/ tephra mod or similar and am wondering if it would be better just to use the stock basemaps instead of copying mine over?

With just 255/tbe/fmic/hks272s installed, would going back to stock maps reduce some of the knock so that I can get it properly tuned? The knock is to the point where I dont even want to drive it anymore let alone WOT log pulls. I know it will probably run crappy but if it helps the knock...

I also have a ix turbo/manifold/uicp/licp/dp/wideband ready to be installed and dont know if the car will even be able to do a log pull with those mods using the stock map?

Any suggestions? (meant to post this in general)

This was a 3rd gear pull @21 on 93oct

 

I can lend you my basemap for the 96420008 for a stock 04 RS the timing and fuel should be really really close to stock for you car if not exact.

Honestly I saw knock with a completely stock map though on the crappy 91 octane we have here.

 

What boost were you running at? If you can post or pm me the basemap I'd like to compare.

 

Depends on the level of mods really

Stock was 18psi dropping down into 16psi by redline.

I think my first tune was 20psi with stock everything minus a TBE which was quite fun. After awhile i got a fuel pump and a MBC and got the boost to 23psi easily. Shortly after an addition of an intake and cams and 880's had me in the 24-25psi range on the stock turbo.

Lately it was 25-26psi on a red with a large FMIC but I currently have it scaled way back to 21psi becuase I'm running with e85 on 880's which is not enough :P

 

Nice

I thought my knock might have been from too much boost but 21/22 on 93oct with 255/fmic on a cool day...

 

Definitely not but do you have a wideband?

Whats your AFR?

 

Have a aem uego on the way, until then not sure how accurate this is.

Heres the map as well:

 

holy crap thats rich

I could probably set you up close with 11.0 10.8 AFR and a mild tune. Run at your own risk though thought i can't imagine it would go boom since it worked well on 91 octane.

 

PM me your email I'll send you the base rom the forum wont allow objects over 100kb here.
