Ambient temps can make a big difference with turbo.

Well the M235i 400R+ DCT AWD that rolled against my 6 speed M2 saw tail lights on all 3 runs. I have reached out to Jaycent at Mpact about slips. And I would love to see the M235i trapping 129 mph, why don't you get me slips as well. If you know him or her personally, I will be happy to invite them out to Maryland Int. Raceway in September 16, 2016 to run.

Here is a link for reference of a M235i AWD that used the factory launch control and trapped 116mph with e30 fuel mix, DP, Piggyback. Click here

I believe you got M235 wrong, since they come with AT not DCT.
What wakeofdeath is saying is that an M2 trapping 123 from a DIG is not accurate but more from the 40 roll as the Mpact Event was for "Roll Racing" correct?

My friend M2TROLL is the M235 DP + Flash tuned that ran 12.1@111 at Atco Drag in April (DIG), was trapping 127-129 on friday (40 roll racing). I was not there friday but I was there saturday.

Anyhow, Pocono Raceway Aug 14th sounds (Slipstream) much better and closer than September 16 In my opinion?


PS.. Those slips are welcome for the public.

[Luminous]

Just to clarify these traps were of roll races at mpact more than 1/4 mile. No way this m2 would trap even close to 120 at the 1/4 mile without upgraded turbos and meth/pi.

Weren't you guys scheduled to release the tune yesterday?

Rob,

Since it appears the mods deleted my last reply to you. I know M2Troll very classy guy, we ran each other at Pocono 3 times. I texted him today and invited him and his girl to MIR on my dime, you are welcome to carpool with them and join. But I don't understand how you feel it is normal for him to trap a 127-129 but for me to trap 123.48 is unusual to you.

Also, I would be happy to come to Pocono again assuming you will pay for my runs just as I have offer to pay for you all.

Now with out upgraded turbos, fuel pump, almost full tank of e85, boost controller, upgraded fuel system (meth, PI, etc)...

Or you had a wind gust behind your car which caused the best run in history.
It might be possible...

My question is: i see the dyno chart you posted, 425 whp, very healthy...
But your not even near 400 on torque. Now i'm not saying you lying, but throwing down 425, you tq should be near 470-485 lbs.

Do you have an independent dyno on a dynojet with STD or Uncorrected set to smoothing 5 to just keep everything on the same playing field?

My 235 is 394whp / 447tq on 93 pump gas. I would think you would have much more than my car since your starting off with nearly 50whp more on that engine.

I would be happy to take it to a dynojet. But seriously what will it solve, clearly there is this idea that a m235 with dp and tune can trap 127 on a roll run but a m2 with similar mods can not trap 124 on a rolling 1/4.

Coming soon I had a few inquires and quotes already given out. If you are actually interested feel free to pm.

[Pat@sonictuning]

I can vouch for TTFS. Great group of guys and they definitely know their stuff as far as tuning goes!!

[kovsky]

Those trap speeds are pointless for obvious reason, rolling starts and non-standard distances... Also, you never mentioned it was a rolling start initially it could have easily been interpreted as a standard 1/4 mile trap speed. In fact that is what some people were thinking. Ridiculous thought of course my 545rwhp M2 might get a 125 trap maybe a shade better.

The dynograph does not mean anything either it does not show a graph similar to any other N55 graph I have seen. My car in stock turbo form made way more torque than HP no matter how much boost we were making ~395/455 on e30. Just like the other non-M2 N55's. The fundamental way the stock motor/turbo develops power should remain similar no matter the dyno. The numbers can change sure but when you see a huge difference in the way it makes power it becomes pretty meaningless as a comparative measure. IMHO of course.

This is why others have posted and asked to see results on a standard dyno and to take it to a standard 1/4 mile track. I'd like to see this done because I'd like more options out there I can trust for a flash tune. Piggy backs have their limitations.. Heck I'm in the market for a DCT oriented flash. Stock clutch packs will slip like a mofo over 500rwhp. I know there is more power to be made by a flash tune as well.

You are correct trap speed are not from a tree based race so it is merely comparing to the guy next to you or others at the event. As for the distance, it is a 1/4 mile from starting cone to ending cone. You should definitely do some runs I would love to see what she traps.

A dyno measures before after gains. Boost delivery can be controlled a great deal through the tune. It all depends on what we want for the application. customer preference and how much Frank like you .

In time we will be happy to do it, after all it will not only help the community but help us. I will see if we can get some proper tree runs at MIR, I am personally curious how she will do, I am guessing in the 115 range may be less may be more.

You are correct piggybacks have their limitations. The power delivery of the boost can help with the DCT slipping some, but it has to be tested to see exactly how much and you are on point over 500whp with stock like torque curve they will slip and slip some more.

[paradoxical3]

115 would be pretty disappointing, I trapped 113mph on a 95 degree humid day with a JB4 on map 1 trying to use launch control....launch control was a complete fail, almost as if it doesn't like the increased torque from the tune.

I was trapping 113mph literally launching with launch control..disengaging the throttle completely to kill wheel hop, waiting a second, and then re-applying the throttle.

When we run our M2 we will see how she does one way or another. trapspeed does not lie regardless of launch. I am happy you are having such good results with your piggy back and thank you for sharing your experience.

Well, generally trap speed will not change much with 95% of launches but you will see an uptick of 1-2mph for sure when launching like I did (4 second 60ft and having to restart from 0mph a bit up the track). Reason being I am shortening the available track to achieve top speed.

I dislike the JB4 piggyback solution and would much prefer a flash based solution. But I can't do that until I see real drag strip numbers, and preferably a few customers beating it on the road course. Or, shops could take on the liability of testing their own tunes on the road course. But I'm probably asking for too much out of most vendors there - actually testing their products under grueling conditions. I am not speaking specifically about TTFS here, frankly I have zero idea if you even do road course stuff. Just speaking to my frustration with this platform in general, which is full of idiots purchasing barely tested "products" for thousands of dollars that are pushed out by vendors with zero QC or actual development, which I could manufacture in China for $5 (I make automotive electronics for a living). The JB4 parts cost is literally under $10. Or for another example of what I am talking about, can you believe that people still actually buy Rob Beck and Vargas Turbos?

Flash tuning is a good start, I just wish vendors would actually post more real data. We need more quality vendors on this platform, but we need data to validate it. I'm not just taking people at their word when it comes to a $20k engine.

[TTFS]

paradoxical3 I understand where you are coming from and hopefully over time we will present the community with some better insight, with that in mind the M2 community is very small right now and I find myself reading posts in other threads by members who do not even own the car, or even driven it, but making comments. I think the M2 will be a nice car for many enthusiasts, we certainly like ours and hope to see new products by all vendors.

Correct, Thats why Fsociety mentioned @slipstream, since they have a custom timing system to measure, record, and print the start speeds. Qualifying runs have to be at 60mph

In for updates and hopefully a turbo upgrade on the TTFS M2 :P

Correct me if I am wrong - you get 21 psi with stock turbo?

Mind enlightening to which rpm can it hold on that pressure to?

No turbo upgrades at least not for another 10k. We were just talking about how we haven't put the M2 on the dyno for tuning since May. For those following the thread this was prior to Wagner's contribution with the intercooler.

The tune is not done, hence the screenshot, but as things slow down at the shop and people take delivery of their car we will spend more time completing the tune for people with bolt ons.

These new dyno numbers looks much better, TTFS what was done now versus before? JB4 being used as boost control etc?

Hope you guys are going to BeastCoast Festival of Speed DIG or Roll Racing Oct 23rd

Couple of M235's and M2's also going would be good to add another BMW

Is it possible to deactivate the auto-blip/rev matching function in the manual transmission M2s with your ECU tune?

No JB4, Terry makes a decent product but we prefer ecu tuning. I think I will entertain your dynojet numbers one of these days. As for time slip hopefully this Friday. The car will be on factory tires and not slicks but we can at least walk it out. You guys are still welcome to join us this Friday at MIR and even bring Enzo if you want (Roll and Dig) and I will gladly get two racers for free.


We will do some track logging to make sure we are comfortable for the release of the FBO tune at high boost and finally list the different stages on our website.

You know you are the second person this week who has asked, we have not looked into it. I will ask Frank for his insight and get back to you.
