Midnite Tuning rollin deep in Supras!

Updates made. Going on soon so we will see how it does. I’ll have Javi look at it he’s a JB4 wiz

That seemed to fix it quite nicely! Waiting to get on the Dyno it’s 81* so we will see how it goes https://datazap.me/u/phantomx2k/bef-jb4-e40?log=0&data=1-3-4-12-14-18-19&hg=19-1-4-3-18-14-12

I did 460rwhp on stock map 5… more coming on map 6

About to find out Friday going back to the Dyno. Yea don’t use the one on Jb4 I have the updated file. for comparison I had the MHD OTS e40 tune made 426rwhp. Jb4 with backend flash did 460rwhp on stock map 5 now I have a custom map 6 that Terry created and @ColonelAdama has been helping me...

I have the MHD Dongle and it seems that works so might have to order this my dyno guy, big BMW shop, was raving about it. But damn why is the Supra iike 2x more expensive

In the top of the custom settings which ones apply to all maps? The Duty Bias?

I actually had one exactly like that, Manual in white my buddy wrapped it around a light pole at 70+mph and almost killed himself while I watched. I just sent him this as a “hey remember this car”

Quick question for the pros. https://datazap.me/u/phantomx2k/bef-jb4map6-e40?log=0&data=1-3-4-12-14-18-19&hg=19-1-4-3-18-14-12 I got this quick ramp up at 4k that maxes trims out and i want to chill it out a bit there and smooth the hump out a bit. Would i adjust duty bias up a bit to slow the...

Custom tune for sure. I don’t think it has a misfire just running out of fuel “range” it can do more stock just the DME stock tune is limited. what ratio of ethanol to fuel did you use? I use this site...

better screen shot as you get over 5500 the trims basically max out until you shift and then next gear same thing above 5500 they max out and the throttle closing causes these little boost spikes in a few places. First one shows what I mean Ideally your get the boost riding right with the...

Looks like the trims are maxing out again as you start to climb in the rev range they start climbing and then it can’t adjust any more fuel and then you see throttle closures quite a bit it seems, It’s pulling some timing as well At one point mid run it was 10.5 and it dropped all the way to...

I see an option to allow allow targets below the DMEBT but not necessarily disable it?

I know it’s been super helpful uploading these to datazap.me (it’s free) so we can run through the runs and get specific values at each point and actually “play” the run and pick out parameter to look at, if you need some help holla I can walk you through it and where the files are on your phone...

I’m still tweaking my tune to get that trim spike out around 4000-4500 I need to pull the boost back another .5psi or so I think in that range Just comparing each for something you can look at, see how the boost target and boost pretty much run right along together, AFR’s good and timing climbs...

I’m still learning my way around these logs some of the things I’ve been looking for in mine are AFR’s staying safe, Trims not maxing, timing progressively climbing toward redline without pulling back and boost riding along with the target. @ColonelAdama i’m sure peaks things like fuel and...

Oh man this makes my head hurt I have so much more research to do LOL

If anyone is interested I found this about avg_ign (this is for the N54 and some of the other N and S engines but maybe a bit different possibly for the B58 but it seems helpful and most of the settings seem to relate to the JB4 in general regardless of engine though values may be different for...

From what I read on here the common answer is yes you should reprogram it otherwise the car may potentially overcharge it seems to be the consensus. You can get an OBDII adapter about $80 and the bimmerlink software, $40, and just reset it yourself, then you can reset all your service intervals...

I see that… starting to make a bit more sense…. I’m still learning so helps when it’s explained I was just posting about that in the other thread and after seeing the explanation looking across cyl definitely makes more sense! Thank you! Having said that anyone know what avg_ign is on a B58?
