Give this a read - fueling section: https://ecutek.atlassian.net/wiki/spaces/SUPPORT/pages/170557464/B58+Tuning+Guide TLDR: The B58 will target lambda 1 (14.7 AFR) unless things start to get hot and it sees conditions that can cause knock. If you are seeing your AFR drop into the 12s, you are...

Going lean down low. Give this map 6 a try. No need to change duty bias yet.

It was like $75 to DIY in 30 minutes with the FCP Euro kit. ...and $300 for race ramps

E25 is a blend. It is approximately 2-3 gallons of E85 mixed in with your pump gas.

Actually hilarious. The first time it makes sense to have the JB4 linked to a single phone ?

Holy hell, me too ? 490 whp is a lot of ponies for a 15 year old. I'm sure he'll do a fine job of convincing his dad he keeps it in Map 0.

i don't really see the reason for the hate. I would love to add a M3P to my garage someday and think its a lovely EV for daily driving. It's just not even close to scratching the itch the Supra does, so I don't see the point in comparing the two. @Phantomx, whoever bought your supra, did it...

Nah, that is set automatically and you can't change it. JB4 identifies your TMAP. Appreciate it man!

Log says it is FF 50 still. Since you got a downpipe too, i would drop Duty 4500 and below by 5.

This is so cheap, surprised no one has grabbed it yet. bump for anyone who hasn't seen.

Looks good. All the info is in the log btw, so no need for screenshots.

Nah, he was saying to turn it up, but I wanna see map 0 first

I'd be curious to see a map 0 log too dyno graph would indicate a similar ecu_psi based on the torque curve

Appreciate it bro! Definitely recommend E85 for if you track it, just keep the same map. Your car is wanting to run a lot of boost, so IATs are going up quick. heat soak likely I figure you are high altitude. Car doesn't hit boost threshold till a bit later, and the higher PSI. That's what I'm...

Yeah your map 1 is the best bet until ethanol then. It will be less than 52 hp for sure. Lots of torque though. I'd guess 30hp?

Eh it is pretty solid. Are you on 93? You could try Map 4 with the same FF

Looks much better now!

Overboosting at lower RPM, can you drop FF down to 40 and try map 1 again?

No sorry. Don't think it is JB4 related. Everything looks good except poor timing. The log you sent was definitely Map 2, shows in the log.

Boost control seems fine, but yeah it is simply too much boost for the octane so it has poor timing. Want to send a map 1 log?
