yup i upgraded my pump to a TU pump and the limit of the TU hpfp is around E30 or E35 anything 40 and up at WOT will max out the Fuel table on JB4 from what ive seen with the logs. Only a BEF will fix it and we would able to do E50 no issues

Unlike older engines that have static boost tables the B58 works by calculating cylinder fill volume from requested torque values. It may decide to run low boost high ignition advance, or higher boost and lower timing. From what I've noticed over the 100s of logs I've done with the M240 and Supra is that it'll run higher boost and lower timing as IATs increase.

Anyway, here's the link:

Yup just got into this stuff last year when i got the car, very interesting too see the differences. learned a lot working with Terry at JB4

Everything else is stock on this car other than the tires. I replaced the factory P7 A/S RFT with 245/40 19 Conti DWS 06+. Plus a K&N drop in filter.

Runs were map 2 at about 3/4 tank of gas (E20 or so) and I weigh in the neighborhood of 210 lbs for the math nuts that want to run calculations and whatnot.

Impressions: Car has ridiculous amounts of grip from a dig. The launch control programming is bananas. The car is a bit heavy and you really feel it up top. If it were 500 lbs lighter it would easily be a 10 sec car. Regardless, 11.35 1/4 for 4000+ lbs is super quick with this minimal level of mod. These times (11.35 1/4, 7.21 1/8, 3.18 0-60) are getting real close to stock G8x xdrive numbers.

The more I drive the car the more I like it. Recently did a 1000+ mile road trip up in the mountains through the snow, and the car handled it like a champ. I'm going to make another thread for that review.

Here's the dragys:


EDIT: Caveat, as the dragy says, it was 29 degrees at sea level and a -2500 DA. results not typical lol

Hendo, I understand you was only on e20 and map 2 plus weather conditions, but how many attempts did it take you to run a 11.3?? I know you said if the car was about 500lbs lighter it would be a 10 sec car all day, but do you think with maybe a lil bit more ethanol, map 4, and maybe some like R888R tires it would do like a 10.9/10.8 not even on a prepped track???

Hopefully Femto comes out with the ODB unlock soon, MG flasher is already on board and all we need is MHD and Bootmod3 to hop on as well. then its bye bye JB4 and check engine lights

Only did like 2 runs lol. Map 4 isn't playing nice. It's maxing fuel trims and pulling boost. I also don't think tires are going to make the difference to get the car into the 10s. I was putting down 1.6x 60 foot times in a 4000+ lb car at 29 degrees. Prepped track is good for a launch, but is also higher rolling resistance. People tend to put better times down on the street assuming you aren't straight traction limited without the sticky surface.

The launch in the G42 is really good, its the weight and top end holding it back. So either weight reduction or more power is needed to hit 10s. Anyone in a warmer location or higher elevation is going to need a lot of help.

Oh, and there is a 130 MPH governor on the car if you got all seasons.

I've reached out to a few people and try to get clarification. From the look of this post it seems that all bosch ECUs are eligible. It would require a bench unlock at FEMTO, but after that you can flash from your phone.

Yup was talking to femto in another thread they indeed do have an odb unlock but doesn't want to release it to do other claiming it as their own.

If your maxing out ur fuel maybe you need to verify it's e20 you have. Get the test kit and measure your e85. The one at my station is pure 85, measured at that so i get an accurate measurement. I say do an e30 mix. At 12 gallons you can do 8.8 93 and 3.2 e85 providing its measures correctly on your test kit. Once you do that give a go on map 5 and see how it runs.

I'm nowhere near that much E. Unless someone at the gas station accidentally put E in 93 tank! I put 2.5 gal of E85 in and topped it off with 93. Should be about E20 assuming winter blend. Map 4 maxes out. I top off 4 gallons with 93 next day. Still maxes out. Run down to a 1/4 tank and top off with 93. STILL MAXES OUT!!!

At this point I went back to map 0 and did some logs. Everything looks normal. And I'm back to map 2. If you want to look at the logs there's a thread over on N54 tech. Same user name lol.

The weird thing is the super aggressive amount of timing its trying to run. 10 to 15 degrees of advance when trims are maxing out in mid rpm range. The car wants to go fast, injectors won't let it

That's why i cant wait for the dme unlock so we can get rid of the the piggy backs. So this was my problem and i eventually did logs back and forth and set on map6. had to make a lot of adjustments to my boost levels and duty bias but all was stable in the end. Thing is i can send you the settings i did but your car like every car will be different. and the most fueling i can run now is E40, if i try E50 it will max out and drop to map 8.

i say drain your tank and fill it up with 93 then do some runs on map4 and map5 and see if your fueling is still hitting the limit. Once it's not move to an E10 blend and log then do E15, E20 and keep logging. once you are stable you should know the sweet spot for your car. it took me one full year to do these things and going back and forth to not have it max out.

also in the end support told me the only way to fix the fueling is BEF with MHD i said in my mind, i would switch in the blink of an eye to bootmod3.....they have an E50 map stage 2 plus giving you 600 tq to the wheel and 510 hp to the wheels. stock turbo, catless dp and upgraded TU FP

Link to thread? I hope it's not Mission Performance's BS article from last yesr interfering with an actual solution that would save time/money for us.

Are you sending logs to Burger?

Don't know how to copy link in the app, once i get to my pc I'll paste it but this is what they said

Our unlock will be copied and claimed by "world 1st'ers" as their property once we will release it to the public, so.. we'll hold it for now.
This was not initiated by us, so hope for your understanding.

Open a case with support and see what Terry says he's really cool.

[Hendo741]

Yup. Made a few adjustments they recommended and the car hated it even more. Reverted those changes and went back to map 2 until nicer weather.

Personally I prefer map 2 to 4 even before it was acting up. I also take every log and plug it into virtual dyno. Map 2 has produced the best results for me thus far.

[kumizi206]

You made any runs on map2 and 93 octane?

[Hendo741]

You can run map 2 with 93. I just put a little bit of E as an octane booster more than anything.

wow the other maps should work fine with the correct fueling. i guess when the weather gets better just use plain 93 and do logging with the other maps, then start introducing E into the mix. who know maybe by then we will have an ODB unlock and we won't have any issue anymore

I know you've moved on to the M4C - sweet - but do you remember what E amount you used with map 2? Any final thoughts/advice for those you left behind? lol

Would you feel comfortable running the G42 M240i with an AA DP, E30, 93, and JB+ in the default position (~4 psi)?
