I just tried a Map0 run to see what they look like stock and I still get this throttle cut off around 4-5k rpm. Not sure what that means but I believe the other data logs on Map1 had them too. What Fuel and Duty Bias would I have? Any other settings I should touch?

Okay sounds good! My last question is do I need a flex fuel kit or anything to run E85 with 91 pump? Or can I just pump 2 gallons of E85 and fill up all the way with 91 while the cars completely stock? I’ll send a data log of the Map 6 and a Map 4 when I get E20/E30. Thank you!

I could try that map6 shortly. Would running that E20 blend solve the timing issue? I’d rather run Map0 on days I don’t have access to E85 and Map1 for days that I do

There was some wheel spin on some of the runs yes. I believe one of them is a sport mode and when I floored it, it went to 2nd.

Gotcha, I’ll make sure to run that E20 Map 1 tomorrow. I’ve gotten 3 more runs in today to see if the logs are still reliable. Sorry for making you do more work, just kind of worried about how much boost it’s hitting on Map 1. https://datazap.me/u/weeritn/2021-supra-jb4-map-1-day-2?log=0

Thanks a ton! I’ll most likely be staying Map 1 for a while then. I’m satisfied with the increased power while staying reliable. When you say putting 2 gallons of E, does it matter how much 91 is already in the tank? I’m assuming it’s the 1/3 ratio.

Gotcha. Yeah in Utah there isn't more than 91 octane anywhere. There is an E85 station somewhat near me that I could try to blend E30. With my power being limited, do you think that even Map 1 is unsafe for me? I don't want to make the car unreliable for just a bit more power. On another note...

What are the timing corrections? Is it okay to have a few of them? I’ve been told that 91 octane in Utah should be equivalent to 93 octane elsewhere due to elevation. I don’t know how true this really holds. Also I noticed that I had boost as high as 22 on the third pull. Is that safe?

Hey guys! First post here. I've had my 2021 Supra for about 3 months now and I've just installed a JB4 with EWG. The only modification it has right now is an Armaspeed CAI. These are my Map 1 logs. I don't think I'll be going higher than Map 1 or 2 but I also don't really know what the other...
