5sfte tuning, for the people who are doing the project now or soon :) Options

[6strngs]

ok, well, I've had a couple different members on here ask me for SAFC/AFC Neo settings for when they get their 5sfte project finished, but want to take the car for a test drive, or want to be able drive it to a dyno for tuning. So, I've decided to post some. here's my disclaimer first: These are NOT intended to be final settings for your 5sfte. in fact, these aren't my exact settings. I actually am posting slightly milder settings than what I use because every engine is different, and what settings make my engine run good could be dangerous for yours, which is why no one has ever posted settings before. but, most 5sfte's run very similar settings from what I've seen, so these would be a good place to start and will give you something to build off of.

For the record, these are meant for cars using a CT-26 turbo, 460cc injectors, an APEXI SAFCII or AFC Neo and a 2bar map sensor. if you're using a different turbo, different injectors, different piggyback, or a different sensor, then these settings will most likely not even be close for you and you could damage your engine!

Throttle point: Low - 20% High - 25%

Low Throttle Map:
RPM...Correction %
800....-39%
1400..-28%
2000..-28%
2400..-26%
3000..-30%
3400..-16%
4000..-12%
4400-6400..0%

(I haven't tuned above 4000 RPM yet, but I don't really ever go past 4000 RPM at low throttle...)

High Throttle Map:
RPM...Correction %
800...-11%
1400..-11%
2000..-11%
2400..-11%
3000..-11%
3400..-13%
4000..-13%
4400..-12%
5000..-5%
5400..-5%
6000..-5%
6400..-5%

again, I haven't really tuned past 5000 RPM, so this map makes you go pretty rich right around there, but that'll be safer since detonation tends to happen around those RPMs and lean mixtures burn hotter and thus lead to more detonation. One more thing to keep in mind with all these settings is that they are all NEGATIVE, meaning subtracting fuel. you shouldn't ever need to add fuel!


Once again, I have to state that these are only to help you get your running after your turbo project is done and you need to drive it from your house to the dyno shop to get tuned. Unless you have a wideband o2 gauge, I'd strongly recommend keeping your foot out of the throttle until it's properly tuned, as tempting as it'll be with the newfound power. if you do have a wideband, keep a close eye on it if you do step on it and let off if you see anything leaner than 11.5 during WOT.

so yeah, I'd love to see some settings from other 5sfte people
