DIY Rom tuning for exhaust pops and backfires W/ romraider - Page 30 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

New results, better video:

Still a good amount of burbles/pops with -8 settings on Engine load column 0.15. Only set it for 2000-7450RPM. Rest were left alone. That has made sure the gas smell at idle isn't there.

All I have is a catback exhaust. Everything else is stock. No flames but I'm really going for the sound only.

And will it work with uel headers and a catless downpipe

are the headers catless as well? if so full catless provides the best pops and flames

Kudos on be extra careful and double checking everything, thats good a practice
for the most part I haven't experience weird low speed jerking, if you dont like the 10km/h disable speed you could raise that to whatever you want really,
And yes, base timing b is left untouched, and you get the same results but without having to feather the gas

@eddieflyinv and @snapplepat Im having the same trouble has him - also have the same CAL-Id ZA1JA01C did what you told him - downloaded ww definitions v115 even renamed the xml just incase, some of the tables got more defined but im still missing about half of engine load higher then 1.4 in base timing B and base timing Idle(ingear)(above speed threshold) stops at 1800rpm

May be off topic but that first videos area creeps the fuck out of me

Sorry for the delayed response,

Thats how those tables are supposed to look in their unmodified form, base timing B table looks normal, and so do all the others.
in mine I changed the rpm scaling for the base timing idle. Rather than the table ending @ 1800 I just combined/ eliminated tge duplicate values and used the last 4 columns to put negative values in the higher rpm range
So theres nothing wrong with your tables, thats just what they looked like before I changed anything,

I've only seen one 86 with it and it was experimental. I'd need a standalone ecu for it, stock wont work. i did give this a shot for a bit and holy shit are the pops and flames huge haha

Can this still be achieved with stock header and edited on stage 1 tune

eddieflyinv · 06-04-2017, 08:10 AM

Not flames but I have gotten some nice sounding burbling & popping with the stock header,

works fine with stock header, stock overpipe and stock frontpipe, ive tried -8 and -10. you just have to hit the sweet spot on the gas. i got a 5zigen pro racer zz catback and resonated 5zigen midpipe. pops and burbles are loud, obviously no flames though
