    Background: Just wrapped up installing an ACF top mount kit with a PTE6062 with ADV o2 sensors, running E30 (E33 according to my ethanol sensor) fuel through a bucketed Fuel-It Stage 2 LPFP. Running the latest ST firmware, along with the BMS ST E85 TS BEF. All adaptations were reset numerous times (besides battery and throttle), o2 pressure and reset options were disabled in the JB4, ADV box was checked in MHD when the BEF was flashed. The Issue: Trims want to get stuck at 25 with no rhyme or reason, which throws AFR out of whack to 20.0+ and sets off an SES, probably causing the car to go into open loop fueling. I drove the car for about an hour this morning and threw a light probably 10 times during the course of the drive. Once codes are cleared, the car drives fantastic until it happens again; which could be 30 seconds or 30 minutes later. I've attached four logs of various driving: 1) just cruising on the highway with no issues and no SES, 2) A log of AFR/trims getting stuck randomly, 3) a quick moderate throttle application with no codes/issues, 4) a quick moderate throttle application where AFR/trims get stuck. I first thought this might be related to the ADV o2 sensors, but when watching Trims 1 & 2, as well as AFRs 1 & 2 simultaneously trims usually got stuck before AFRs got screwy. This makes sense as Chris says these ADV sensors are more fuel sensitive. Any help would be appreciated as I'm fairly certain all the hardware/software has been installed properly. I feel like I've quadruple checked everything at this point.

    A stock C7 Z06 is a strong car and a great barometer to race against. If you can top a C7 Z06 from a roll, you have a fairly quick car. This E90 335i automatic puts up a pretty good fight against the American torque monster. The weight between the two cars is actually fairly even. The 335i is on full E85 at 22 psi of boost with port injection. It also has a VFSF intercooler. The Z06 ultimately pulls past up top. If you don't want to get pulled and get taunted, you better be pushing more boost in that 335i.

    Obviously the spinning crank hub issue has been a problem for high power F80 M3 and F82 M4 vehicles. Maximum PSI themselves spun their fair share and came up with a solution that is very similar to Gintani's one-piece keyed S55 crank hub. It's not a cheap solution which involves drilling the factory crankshaft but it seems to be working. Either do it for peace of mind or don't mod your car so your factory warranty stays in place. If you're into warranties you'll never have an 801 whp graph: That is with a built S55 motor on full E85. The turbos are still the Pure Stage 2 units. Beyond that, Maximum PSI isn't saying much and they should know better than posting a graph without correction figures or RPM showing. Still, topping 800 to the wheels is certainly impressive.

    kaldyn55 started a thread Misfires and lean issues. in N54
    Good afternoon all! I have 09 BMW 335xi with JB4 and intakes and running map 5 always. My car has been misfiring at idle for sometime now.. but now I have been getting misfires at 6-5 gear. Example if i am in 6th gear doing 70 mpg When I floor it I get bad misfires. The only codes I got after my car goes to Limp mode is 29F2 and 29E2 I have changed my plugs and coils about 4k miles ago and my spark plug look nasty .. (pictures included) I did also compression test when engine was hot and I get 165 PSI on all cylinders... My car currently have 64k miles only and i always use 93 gas. I have attached picture of codes , picture of my spark plugs that have 4-5 k miles and JB4 logs (no misfires in 3rd gear) 1 log is on map 5, 3rd gear Wot Second log is map 2 after o2 adaptation reset with Jb4 (Jb4 option 1/7) Please help i need to fix this before i install single turbo kit,,,, I have Index 5 injectors BTW I did also change my fuel rail sensor from another used car trying to fix this issue but didn't get any luck after sensor swap.. My JB4 also goes to Map 4 frequently which is Lean error.

    Now this is a hell of a way to deliver some Grey Poupon. Rolls Royces are supposed to be the epitome of class and sophistication. Well, this one decided to throw class and sophistication out the window and go for a full drag build. A 462 cubic inch GM V8 takes the place of the factory 6.75 liter V8. 462 cubic inches is 7.5 liters so they went even bigger. Normally a V8 of that size would be enough but to really make a point a blower sticking through the hood is necessary. That is where the Mooneyham 14/71 supercharger comes in. Then of course since this car is going to be putting down a ton of torque so the tubbed rear gets 12x15 inch Hoosier slicks. Throw in a cage, a side dump exhaust, and a bottle of champagne for those in the back and the result is a Rolls Royce on American steroids. If you hate this you must be British. You also must be no fun at parties.

    Very cool to see the difference in acceleration between the 991.1 and 991.2 generation GT3's. Remember, the 991.1 GT3 has the 3.8 liter flat-6 which was introduced with some major problems. Porsche ended up fixing the issue and giving owners a 10 year 120k mile warranty. The 991.2 GT3 has a new 4.0 liter flat-6 with no major reported issues that pulls to 9000 rpm just like the 3.8 but it is said to offer 25 more horses on paper. A dyno overlay would be great to see but real world comparisons are also great. The first run is a roll race between the GT3's and wow does the 991.2 sure look like it making use of more than 25 more ponies. It pulls quite hard on the 991.1. Race 2 is a launch control dig and the 991.2 gets a jump and pulls away. Race 3 is another roll but the 991.2 jumps again and trounces the 991.1. Wow! The 991.2 GT3 tries the Huracan on for size next. They go from a stop and the GT3 gets a nice little jump allowing it to hold a lead until the Huracan's power takes over past third gear. The roll race is up next and the Huracan just pulls away. No replacement for displacement, eh?

    Tuppidsay started a thread Meth Problems in N54
    So before the car went down for 3 months the car ran great. Meth injection activated hard/instant in my logs. The car had a good timing curve peaking 9ish degrees (pump + meth) . I was very happy with it. Then the car went down.... Since the cars been back up, the meth system has been a constant issue. First I had check valves go bad, then the solenoid fell apart (vibration), leaks, etc. Now that i think i got all that hashed out, the meth doesn't kick instantly or close to instantly anymore. The graph is far more curved than it ever used to be. timing has had to be reduced throughout the curve to keep the timing drops at bay. Im wondering, does it look like maybe the pump is weak? I've had the manifold off with everything still hooked up and tested it. Spray patterns and mist all look good but I have a nagging suspicion that maybe sitting for a few months with 100% meth in it, it's taken a shit... Any thoughts or experience? Getting help with meth in an age of e85 is tough. Thanks to anyone that takes a look. Before she went down: Now:

    The Gen V Viper is the car that enthusiasts everywhere should love and respect. Everyone complains these days cars are too heavy, poorly balanced, do not have manuals, and that they lack race bred naturally aspirated motors. The Viper is everything enthusiasts supposedly say they want. It's a spectacular vehicle that deserves more praise than it gets. This example in the video has a heads/cam upgrade and long tube headers. It is tuned on pump gas. Output should be somewhere in that 650 wheel horsepower range. In the first run it takes on a twin turbo Terminator Cobra. The Cobra is in the ~1000 whp range. The Viper gets a bit of an early start and just leaves the Cobra. They run again and the Viper opens up a nice lead before the Cobra shows it is making 1000 whp. It takes a couple gears but the Terminator eventually pulls past easily. A twin turbo Foxbody is up next and it's fast. It hangs in better off the start than the Cobra and pulls. Next up is a C6 ZR1 with bolt ons and nitrous. Holy crap is it fast. With the nitrous that is. Without it, the Viper pulls. The final challenger is a FBO heads/cam ZL1 on E85. The Viper is able to pull it up top. A well driven and strong Viper that certainly punches above its weight. Now imagine if it had some nitrous or boost thrown on top?

    The 91 octane tuned N55 comes out on top? That shouldn't be the case but the JB4 tuned white E92 335i in the video is running Map 1 on E30. The 335xi N55 camera car is said to have the MHD Stage 1 OTS (off the shelf) tune on 91 octane. You would think the heavier 335xi with its all wheel drive would lose the roll race. Seems the JB4 tuned car needs to run a different map. Both are automatic and both have the Cobb chargepipe:

    Yes, BMW built an M5 CSL that was stripped out with a cage and no rear seats. It also had a DCT transmission unlike the SMG-III sequential manual of the street car and an S85 V10 stroked to 5.5 liters. It's the M5 BMW knew you wanted so they teased you with it and then decided to make another SUV instead and laugh all the way to the bank. If you want to replicate what BMW would not sell you, that is where Germany's Motorsport 24 comes in. They have an incredible parts catalog that will let you build everything from an E30 M3 DTM replica race car (with original DTM parts) to an E60 M5 CSL. The E60 M5 CSL had a 5.5 liter motor but Motorsport 24 offers a 5.4, 5.6, and 5.8. These will each run you 17,900 Euros. You'll probably want the headers too at 2690 Euros. Well, you'll also want the airbox kit too and that is 4950 Euros. All of this adds up fast, doesn't it? That is before you even get to the suspension and differential. The only thing missing is the DCT transmission. For that, you'll need to talk to Gintani.

    Far as routing goes, it sure looks like moving the radiator/condensor/P/S cooler to the bottom and putting an intercooler in it's place looks simpler. Then we wouldn't have to deal with all the intake bends and it looks like it'd be a straighter shot to the rad too. I just can't stand playing with charge pipes popping loose and not being able to fix on the side of the road.
