I will be heading to the track after work today in an attempt to improve my stock times. The conditions (as far as I understand) seem to be pretty good.



I've purchased Bm3, VRSF IC and Catless DP. Once I receive my OBD connection for BM3, I'll run stock once more the next time I make it back to the track. Then I'll flash STG1 just for a fun comparison with identical conditions.

Nice! Yah those conditions are great. Also, good idea to run stock and stage one same day, though I'd just caution you against making your first flash the one you do at the track. Flash the car maybe a week or more before you do the comparison, and then flash to and from stock while you're at the track. This way if you have any issues with the tune when using it for the first time, you don't have to deal with them at the track.

Good call. Also, because the ECU will need to "relearn" and I'd rather have a clean "learned" pass on the stg1 rather than on stock tune.

Right. So flash a week or whatever before, make a pass or two on the tune, and flash to stock for comparison. Curious to see what the results are!

Well, I've got a slight bit of bad news. In my stupor of excitement (this track was only 10 minutes from my work, so I was hyped) I didn't realize this was an 1/8th mile track.

None the less, I wasn't going to make it a wasted trip and I had a blast. Took down a big tire S10 looking truck (he wasn't spinning, it was just disappointingly slow for the "hot rod" look and sound it had going on, the slips at 6:09 and 6:19 are vs the truck in the picture) and a somewhat modified 2016 Coyote ( he spun bad enough for me to win while he trapped 10mph faster than me) and a few others.

Once again pretty impressed with this thing(being stock and all). Weather conditions definitely made a difference but still didn't improve the 60' that much. I again had no spinning, traction control off, brake boosted as 2nd beam lit.

Now, I don't want to be "that guy" I was mocking in a previous post...but if we we're to calculate the rule of thumb with 60' fts (1 10th less on the 60' = 2 10ths in the 1/4), I may have ran a 13.9ish in the 1/4...theoretically. Obviously I'm not going to stick a flag pole in that time as we can't know for sure. But I will certainly be giving it another shot stock in this good weather on the 1/4 at Bradenton.

Ssssoooo....

As an update to this thread:

The weatherman was calling for rain today so the Sacramento Raceway was closed...

It was supposed to be the closing night for the season but we are in luck!

Track management has decided to try one more time, next Wednesday to get a final night in for 2018.

We are all crossing our fingers hoping to get out...

AFAIK, N26Ghost and Diegov209 are planning to run which will initiate some action on the N2X Speed Rankings!

Special thanks to Dheeth-F30 for getting the info for the group

Haha 1/8th is still fun! Nothing for the board but good data and thanks for contributing nonetheless. Looks like you did pretty well too. Those times are pretty good for a stock car, especially the trap speeds

Flashed stg1 (91oct to keep it safe)last night. Nice little bump in power. Though if I am looking at logs right, I hit 25lbs of boost at one point...hoping I am wrong, lol.

I'll be heading back to the 1/4 this Thursday, so we will see what stg1 looks like on a timeslip. Weather will be alright, but not as good as the other night.

Doesn't BM3 allow you to set a max boost target?

How does one prevent against overboosting the engine (like you may have done)...

General consensus is to not push this motor over 22psi. I plan to keep mine at 20psi max.

Not entirely sure to be honest, but I would hope that these parameters would be set for an OTS map. That's kind of the point(of an OTS) really. I have to believe this was a faulty reading, because my stock CP survived, I got no overboost codes, and the rest of the pulls showed around 21-22.

Just found the log - unless "boost pre throttle" is not the right parameter to monitor...definitely shows 25psi.

BM3 sets the boost targets for you within the tune (naturally) and that is not something that you can configure yourself. Overboosts are prevented by the DME itself and the programming within the tune, though it's near impossible to actually overboost with a true flash tune, or at least I've never seen it happen. Overboosts are more common on piggybacks where there is a bit of latency between the piggyback getting the info on what's happening in the engine. This can allow boost to get too high, and the piggyback will realize that eventually, but because of that latency, sometimes it recognizes it too late. This is what happens when you hear about overboosts, almost always with piggybacks and for this reason. Because a flash tune modifies the table within the DME, an overboost is near impossible or at least very unlikely. And if it were to happen, the DME would be quick enough to recognize it and rein things in before anything bad happened.

I think what you experienced was a mis-read and/or generally artifactual. Typically boost pressure is monitor with MAP [psi] no pre-throttle, and because the MAP psi looks good, I would say that you just had a little mistep in the log getting data. I've seen some really weird numbers in my logs (AFR's > 100) and those just happen sometimes when the logger spazzes out. Just like anything else, the software is not immune to glitches. If you got consistent MAP psi readings of 25, then I would be worried.

Good to know. I was worried

Managed to only get one run. It was a disappointing 60 as I haven't ran since the STG 1 flash(had lots of wheel spin this time). I was hoping to run again after adjusting the boost by gear reduction for first, but too many messes on the track prevented me from doing so. Definitely an improvement. A good 60 would net pretty impressive numbers for a tune only set up.

Not too bad! Definitely could go quicker but that's a good start

Get that 60' down to 2 seconds and you'll run a 13.4 or better.

Updated.

Let me know if you see anything that needs correction.

I think below 13.4 is a stretch, as in, I think 13.4x is the best a stage 1 car can do. When I was still on stage 1 the best I could do was a 13.46 with a 1.94 60' in good conditions.

To be fair, if I replicate my 1.9 60 then theoretically I should be able to do only slightly better than a 13.4 as you were able to get 13.4 at 99 mph. Being rwd, little less drive train loss should equal a slight higher trap speed (with right conditions/right launch).

Lots of if's of course. So hopefully next time I go, I can get more than one run in.

Good point, you might be able to eek out a mph over my stage 1 times being RWD assuming you launch well. Good luck if you end up getting back out soon

Car: F31 xDrive, ZF8. 4020lb with driver.

Track: Maple Grove Raceway, PA in Oct 2018

Mods: Dinantronics Stage 2, Dinan IC, aFe drop in filter.

I ran the same (crappy) 60' just about every time. I used launch control as I was 'bracket racing' with coworkers so consistency was key. Next time I need to experiment with the launch as I see many people on here with significantly better 60' times. I really wanted to run a 13.5x that day but my 60' fail stopped me.

Not bad! Thanks for sharing, first wagon entry. What were the conditions like when you made this pass?

No problem. How do you recommend I launch next time?

10/18/18 I ran my best pass around 330PM. If I'm using the drag times calculator properly DA was -589.
