Post dyno chart and JB4 datalog. catless DP MUST be tuned for...

Glad we found the issue! Looking forward to see the dyno gains!

Yep. Only on a car like a Supra would 440whp sound like "not enough" lol. ~500bhp from a stock flash car on pump gas?

@SupraGR3.0 , @sa90h , @mustafazumit You guys just wanna PM me your latest logs? These are all needing a bit more work and it is hard to keep track of revisions here. This thread is good for a quick review but not trial & error thru multiple revisions ?

eh if they really wanted to... I recently worked with someone who had their turbo replaced under warranty despite JB4 Map 3 killing it ? please don't run map 3, especially without tuning for your catless DP

Nah you can try Map 4 with your current fuel. Its actually more conservative than Map 2 in this case. The boost control is totally fine in the last log after the duty/ff changes, its just that your car (much like @sa90h car), is wanting to run high boost to meet load targets, and that is...

Yeah it helped, but still too much boost and timing isn't great. Can you try out Map 4 next? Make sure to set FF to 25 after you switch.

Yes it is. It saves per map, so if you switch maps, you need to set it again. I don't think anything is wrong, just that the additive map is pushing too much boost. You can try map 4 on E20, it will be less boost than what you're running now

Please drop FF to 25 and try again

No prob! You too!:drive:

Yeah give it a try. No more than 3 gallons e85

These are the settings I typically recommend for catless cars nowadays: FF = 25 duty_15 duty_20 duty_25 duty_30 duty_35 duty_40 duty_45 duty_50 duty_55 duty_60 duty_65 duty_70 50 50 50 50 50 50 55 60 65 65 65 65

I wouldn't use more than 3 gallons E85 total to do a first Map 4 log. Bit 3 makes it so the JB4 can target boost levels under stock if it needs to.

Timing is like non-existent unfortunately. Can you send a log on map 4 next? It should actually drop the boost compared to map 1. Enable bit 3 too looks good!

You really gonna make me dig up the datalog of it happening?? smh?

Yup that's it. Think the owner said it should be repairable. I've seen Supras in worse shape at the TBR shop ?

Can you send another link? not working for me Closest bet to 450 is Map 4 probably, if your timing holds up. not very likely on just 93 2-3 gallons of e85 PM me your email and I'll send you the MT JB4 firmware and a map that should work decently

Yeah sorry man, just an octane issue. Adding 2-3 gal of E would change everything

It's easier than that ;) 440whp is no problem for most 93 octane cars on JB4, just got dyno results this week posted on my thread. Expect 460 whp+ on e-blends. not all dynos are the same, of course. Gains over stock is the only number that really matters

Didn't that car end the weekend in a barrier?:( Saw TBR post about it.
