Just downloaded the latest 7/03 firmware from Terry.
Interestingly enough I did the first run, and was kind of disappointed that it was barely 122mph, when yesterday I got a 122.4mph on dual nozzles. After doing the first two runs, I realized I had been running on only one nozzle. (Valve was shut) the first two runs. So I opened up the valve to the second meth nozzle, wondering if the traps would go up or down.

Timing on the 2nd run was pretty poor. I am thinking the first run was still on adaptation from the 2 nozzle runs from yesterday. So perhaps after the 1st run today on the single CM10 nozzle, the DME saw there was too much advance, and therefore timing and traps went down the 2nd run. On a hunch, I did a couple full throttle 3rd gear pulls before the 3rd and 4th runs on dual nozzles. Amazingly, the timing looks way better, and traps hit 123mph. Two runs in a row!

Yesterday was the first time I really noticed an improvement with 2 nozzles after giving it more time to adapt. Today confirms that again fairly strongly. I don't know why it was so obvious today. Don't know if it has anything to do with the new firmware?

91 Chevron. 100% meth, CM10/CM7 testing
Map #3. 50 additive. Meth max: 99
New 7/03 Firmware just installed.

Single CM10

Run#1 11.8 at 122.0mph 1.9 sec 60'. CSV 0732
0-60: 3.6 sec, 0-100: 8.1 sec,

Run#2 11.9 at 121.1mph, 2.0sec 60'. CSV 0741
0-60: 3.7 sec, 0-100: 8.3 sec

CM10 + CM7 Nozzle

Run#3 11.7 at 123.0mph, 1.9 sec 60'. CSV 0754
0-60: 3.5 sec, 0-100: 8.0 sec

Run#4 11.8 at 123.0mph 1.9 sec 60'. CSV 0802
0-60: 3.6 sec, 0-100: 8.1 sec

And yes, 123mph Vbox would near record traps (with the +2.7mph during the Sacramento hey days) for a stock turbo 335i, and without the 10mph tail wind of Sac, and still using the stock catback, stock intercooler, no lightweight flywheel, Race fuel, etc. Also consider these consecutive 123mph trap runs were the 3rd and 4th of back to back runs. Pretty impressive. And it all makes perfect sense, since a 11.7 with a 1.9 sec, would be right at the 11.5 with a 1.7 60', all things being equal.

This is testing is very effective of showing even the smallest gains. That is over ten logged 0-130 pulls since yesterday, same temps, etc. Just look at the last 2 runs...exact 123.0 mph traps..how is that for consistency! And though I could short shift and perhaps get a higher trap, these runs are all auto shift, DS manual, 2nd gear launches with no warmup burnouts for the sake of meaningful test results.

So, Sac's trap speed is accurate now?

[Irishace]

Has nothing to do with SAC. 123mph is more than achievable on stock snails, I have done it in Toronto with my car. HR's car has some weight reduction which puts it right in line with my 135i weight.

Solid post HR, I am dropping in the new firmware tonight and will be doing some testing.

I have an even newer firmware now, with meth boost additive auto tuning!

Sac was actually the opposite now. Slower by a couple mph I believe. So you would be a whopping 4-5mph slower now! Well thats when Mr. 5 checked it with his Vbox lately. Hopefully they corrected it some more now. Maybe someone can go out there with a Vbox and verify. ETs seem to be correct though.

I wrote and got a response back from the track. They said the traps were artificially inflated during their period of renovation:

The Infrareds were moved temporarily, shortening the track, for construction purposes. This project started in spring of 2009 and ended in fall of 2010. Your times would have appeared slightly quicker. The new boxes have been built, to avoid misalignments during events. The top end was resurfaced, removing some infrareds. The timing equipment is calibrated twice yearly by NHRA. They were corrected shortly before the ET finals in October of 2010. Each mph reading on individual cars can very slightly due to their equipment, tire and wheel size.We cannot change or adjust speed conversions through computer access. It just does not work that way. The only calibration we can make is with the roll out, which can affect your RT, 60ft. times, 330. You are now experiencing a true 1320 reading. If you have more questions about how the timing equipment works you can speak with Tony Trimp, he was there during the whole process. Unfortunately, this makes ET's, for some drivers, and mph slightly slower but is a true time. While it was great ET's and mph its as useful as buying a trophy instead of winning a trophy. If that makes sense. This passed weekend NHRA held their 3rd annual Sportsman National Open. All timing equipment was calibrated and cars set 7 NHRA records. Sacramento is said to be a fast track in general and has been that way for 41 years due to the air reading. We are one of three track in the world that is at sea level. Take Care.

Where can we get this 7/03 update? Nice trap speeds!

[Brey335i]

You know what I like about your posts, Hotrod?

You always write an informative post backed up by quality data.

Very nice. What was the highest trap speed of the coupe?

I second that, always very informative... nice job and fantastic results HR.

There is going to be nothing left of that car when your done with it !.... you should consider an on off switch instead of a gas pedal.

[Dr. G]

HR, you always have the greatest posts haha.

I'm the one who messaged you on the other forums about the meth setup, and you showed me a DETAILED post with TONS of testing showing the results of meth w/ and w/o downpipes.

Love reading your posts, very informative and detailed.

[Irishace]

Firmware is limited release at the moment for those helping Terry with FSB testing.

[hotrod182]

Thanks guys....with hundreds of qtr mile passes...and dozens of 130mph+ nitrous passes....I have always said the DME.does a remarkable job of protecting the motor.FYI, I had the CPS module and never used it except for a few test runs.

All I see is the 6/4 update?? Where is the 7/3???

Great post hotrod, I like to see this kind of detail in testing. I don't know if you have or not but it would be interesting to see you test different meth mixtures such as 49/51 and 70/30 then compare those to 100% meth to see how big of a change it makes.

for sure... that would be great to see.... how much of a drop for less risk of 100% meth - maybe do 75% meth and see what happens to your times.

[ZTZ1010]

guys.. RELAX. you'll all get the firmware once it's been thoroughly tested and tweaked. HotRod is typically one of the first in the limited alpha group, which usually saves the rest of us a lot of headaches with preliminary testing as new firmware isn't always perfect and ready to be released fully to the public. Chill. it's coming.

Nice Results HR, can't wait to get my hands on the additive meth AT as well.

[Turkeybaster115]

Hotrod, did you end up replacing that slipping AT?

[hotrod182]

Nope, never had to replace any BMW trans. They seem to work flawlessly in the 123mph trap range. When on N20 and 130mph+ traps, the trans is very strained...however the JB4 with shift cutout, etc...has been doing a very good job with dozens and dozens of 130mph passes.

All you have to do is look at the RPM graphs in my first post to see how nice and crisp the shifts are after the RPM drop into the next gear.

I too am very interested in trying a diluted mixture of meth, but it will have to wait till I get some more tests on the newest firmware from yesterday, as I don't want to skew my baseline results...

You mean you didn't replace the trans after this?:

Looks like blown clutch packs to me.

[hotrod182]

Nope...trans works perfectly at lower power levels. You can always get the trans to act up under certain situations where it upshifts, then regains traction, down shifts at the lower rpms, or hangs at a certain rpm. But that is more trans shift logic than clutch packs. Also, when the trans sees slippage, or something it doesn't like, it will go into the default mode, which is 3rd gear. And of course if you are going over 100mph, then it will rev the engine.

But again, as evidenced by how nice the car shifts, and runs in the mid 11' second range, 123mph traps...I don't think most modders will see any problems. Nitrous..(130mph), RB Turbos (127mph traps). Are probably exceeding the normal limits of the trans, so you need fail safes for cut the N20 or need to beef up your trans. There is a trans buildup thread on the other forum for the guy with the RBs, we will see how that turns out.

Hotrod, since you have the most 1/4 mile experience of anyone here, what time and trap will my 6AT run at the dragstrip (70 degrees), with just JB+ set to 50%, everything else stock?

[Irishace]

Just executed this log today, T is really dialing it in with the new firmware and FSB integration. 3rd gear pull, 90/10 meth mix, 94 octane pump gas and 17.5 psi.

[hotrod182]

Have been driving around exclusively on the dual meth nozzles. Downloaded the latest 0712 firmware. Tested again, to find the traps averaging over 123mph. The two runs at 123.3mph would probably be among the fastest recorded runs for a 335i on 91 octane/meth/stock intercooler/stock rear catback. Again...123.3 would have been 126mph at Sac. And there is no stock turbo car that has trapped 126 at Sac even in the glory days. Certainly none with stock intercooler/exhaust. And as you can see on the video no attempts were made to short shift. 11.7 with a 1.90 60' as I drive the car on the street is not too shabby. (No warmup burnout whatsoever, 2nd gear launch) Also note how perfect the auto trans shifts are. Again...at sane power levels...trans has no problems whatsoever.

53F Calm, 91 octane Chevron+dual nozzles 100%

Run#2 11.8 at 123.3 mph, 2.0 sec 60'
0-60:3.6sec, 0-100: 8.1 sec,

Future use B set back to 0 (enable meth boost limiting)

Run#3 11.8 at 122.9mph 2.0 sec 60'
