2007 STi Speed Density/Flex Fuel - Another Cobb Refugee

badwheel · **Posted:** Thu Sep 08, 2022 12:16 am

Hello,

I have an 07 Sti with a BCP X500+ on e85 that i was just about to convert to speed density when all of this Cobb stuff went down. I was using Acesstuner and am familiar with open ECU and have switched the car over to open ECU without issue. However the maf limit has severely limited me on boost. Is speed density an option for this car (a bonus would be having flex fuel as well - but i currently don't have a flex sensor installed)? The only other option I see is a big maf intake but I am not sure how well they do at idle. I would be happy to pay someone to get me a base map/defs for speed density. I am familiar with tuning speed density as I did it on a evoIX a while back. If any one has any guidance on the quality of running a big maf intake i would be all ears as well.

Quick edit - my ECU ID is A2UG000J

Have you heard anything on this ?

There's a speed density tune available for your STI. Not sure if it has flex fuel, but I can have a look if you're still looking for it.
