I gotta wonder how this flex tune actually works if insufficient octane literally provokes the car to target 42 psi at redline lol. My understanding was that flex tunes kept boost levels similar and adjusted base timing based on E%. If it compensates timing corrections with boost to hit the...

Don't click any rage-bait reels and you may be fine ? Platform is just full of clout-chasing posers, but plenty of good people too.

I'd love to own one but hard to justify 4-5x the price of my GTI when it's similar enough of a car (for daily purposes)

Real. Considering a Model 3 to replace my GTI as a daily next. Supra scratches the "driver's car" itch for me. As awesome as the GTI is, would rather auto-pilot to work some days for nearly no travel cost, and save the fun drives for the Supra. Needing a 4 door for the growing family, will...

Instagram is the worst I've seen "fake toyota? get your money up and get a real M car" ~some dude in a clapped out financed F80 the general rage-bait all over the car scene is unbearable

They probably won't show you the log for that ? not letting anyone here run shitty timing.

prob not! I'd just stick with the JB+ unless you want to switch to E30.

You'll definitely get a lot more midrange power. Top end is a little extra, but yeah 91 octane is pretty limiting. If you are stock DP, you can probably just run Map 1 on default settings V28 firmware.

Definitely worth it to get octane up. power capability is much higher.

Yeah timing isn't super clean so I still wouldn't exceed Map 1. It will just have more timing corrections and rob any power from the extra boost.

typically the +6psi ask is a bit much under 5k rpm for the fueling so trims usually max out (because E30 is needed for clean timing). Its a better fit for the non-M40i b58s that run 3-4 less psi than ours factory. You can probably get away with it if using 93+ octane booster. But generally...

Yeah I'd be less inclined to enjoy being followed to my house... But its hilarious, now this group of kids wait at the front of my neighborhood for me to drive back after work ? Just to hear it rev. I really do have hope for the next generation loving proper sports cars. Neighbor has a new(to...

Yeah it can round a tenth or two, no worries. Won't make a difference.

Great, so stay the fuck out of my thread then. Trying to help people here.

ngl man, it is pretty annoying because you assume everyone already knows how to fully dme tune any car, or has the time to be trained on it I don't have enough hours in my day to learn to self tune 2 completely different platforms for negligible gains. Especially when the risk of fuck-up is...

IATs are a bit higher, May be worth running a map 6 somewhere in between map 1 and map 2 on that fuel. FF to 45 after switching to map 6 map6_15 map6_20 map6_25 map6_30 map6_35 map6_40 map6_45 map6_50 map6_55 map6_60 map6_65 map6_70 1.3 1.8 2.3...

I got the JB4 in 2016... lol, been doing this a while. Car is a 2015. I don't unlock cars till they are paid off. Drove a "stage 2" unitronic GTI. Mine was much faster, easier to log and switch between E30/93 maps. Never cared to flash it after that. Only if going big turbo, but I have open...

yet... lol. Terry is working on an O2 spoof but not sure how brave I'd be ? ? ? bias it into the 13s its like biasing a knock sensor... like uhhh idk. He's only trying it since that dude in this thread ran no O2 sensor and it fixed all the MT injection-monitoring issues Damn now that I think...

Timing is already being pulled so no point in exceeding Map 1. Yeah the FP upgrade just raises rail pressure a little so trims stay under control when you blend ethanol. which I would recommend if you want more substantial gains.

Need to see all ignition timing (all cylinders) on the graph for map 1 first
