OK so today Shiv installed his Proceed and Meth kit on my 2011.5 M3. Lets start with what has been done to my car. I have a magnaflow cat back, a resonated xpipe with high flow secondary cats and OE tune. Everything else is stock. My car ran good, felt strong and ive been driving it happily.... Or so i thought.

So we get to EAS and strap the car onto their dyno. We do a couple of base line runs to to see how my car has been running. You can see in the dyno sheet what my car did with my mods and a OE tuning tune. Im not sure if something changed, or what but the results are on paper. You can see these results in BLUE.

Since Shiv wanted to get a stock car/tune pull, i had EAS reflash my ECU with a stock tune. Absolutely awesome. Took an hour and worked like a charm. Again we dyno it with my mods and with the stock tune. You can see the results on the dyno sheet in GREEN.

We then plug in the Proceed and power up the meth. Shiv worked on the tune a bit and the results are shown below in RED. You be the judge.







The sheet shows power, but how does it translate to driving it. Like i said earlier, The car made noise, pulled good and i thought i was doing good. WAS I WRONG! After i left EAS with the Proceed and Meth it felt like a complete different car. Not a yea i feel it.. More like WTF is this the same car. I had more tq, as the needle reached redline i was like omg. As i shifted into 3rd i see the traction light start blinking in MDM mode! It feels like the car is happy to rev. The motor feels smoother even. Shiv did his magic.

Now as you look at my sheets, remember, this is a stock car with high flow cats and exhaust. Nothing else. Stock intake and no pulley on 91 octane pump gas.

I would like to thank Shiv. Amazing customer service, great product and cool dude. I would also like to thank Tom at EAS for helping us out with the dyno time and the reflashing back to stock.


Also, a special thanks to Kenya. Good Girl!

nice job OP... seems like the OE Tune made you LOSE power vs gaining any. strange.

On these charts it says "OE Tune + Procede, Meth 50/50" . I thought the 'Procede' portion of this is a tune itself? So shouldn't that replace the 'OE Tune' ?

The OE tune was removed right after 2 runs. It was no meth or no proceed.

Ok makes sense. The Dyno charts are labeled incorrectly. The labels make it seem it is all on there at once.

These high compression motors seem to be octane and heat sensitive. Meth addresses both.

Hi guys,
Great fun today. Thanks again to Tom at EAS for his time today. And for Donald and Rudy for taking care of Kenya while I was on the dyno

I finally got a chance to look at the data again. As mentioned, the labels for most of the runs were wrong. I also noticed at the stock tune run in Donald's dyno graph was done in 4th gear while all the other runs were done in 5th. So I found another 5th gear run of the stock tune and used that for reference instead (it made 2whp more). I also applied an STD correction and forced scaling so that both axis are scaled from 0 to 400. I also edited the run info to reflect the tunes:



The car only has basic exhaust mods, so there is still a good deal of power left on the table. With pulley and intake, we are hoping to see north of 420whp.

Here's a pic of where I mounted the nozzles. Usually, i put them in the charge pipe but this time I wanted to hide them completely in the airbox and move them more upstream:


I'm flying to El Paso Texas next week to install a Procede/PWM meth kit on two fully modified m3s and hopefully we can get some bigger numbers

Cheers,
Shiv

Am I seeing this right? Your car made 13whp more power with a stock tune over OE's Tune for all of your mods? Power delivery of the stock tune also looks much smoother than the OE tune. Seriously, the OE Tuning power delivery looks very bad.

Looks like the end results are very strong. Sorry, I am still confused on which runs are which.

Would it be possible to signify which are which on the latest dynos posted by Shiv?

The problem is quite simple: I had that AFR problem / curve with my stock tune almost exact to that OE AFR. It was based on a primary 02 fault I was experiencing. I had to clear the 02 fault first. When that lean the car will lose a ton of power from timing retard. I rectified the issue and it's a brand new car.

Glad to see you're coming to Texas, Shiv. We run 93 octane down here, and I'll be interested to see the results of a 93 octane-based tune.

Is the windshield cleaner fluid bottle used to house the meth mixture?

BTW, I'm sure I'm not the only one curious about pricing

If I were you I'd stick with the green HP curve. That's the only one that has a correct A/F ratio.

You're getting the extra power from the red curve by running it lean.

Sure. Blue=original tune, Green=Stock tune, Red=Procede tune w/PWM Meth

We were all a little stumped by the first runs. I even checked for/cleared all codes. Even did a few DME resets and logged lambda. Both bank1 and bank2 were on target and running ~15.x AFR under load. So we definitely weren't dealing with a bad sensor.

Yes, we are using the windshield water bottle for the meth/water mix. Should have pricing finalized after the Texas trip.

There really is no "correct A/F ratio". But rather a correct one based upon supporting mods/conditions. In the case of the Procede/PWM meth combo, the operating conditions change dramatically: Intake air temps drop 40-50F and effective octane jumps to 100+. So targetting a slightly leaner AFR is perfectly safe and desirable. It's also worth mentioning that dropping AFR targets down to ~12:1 only reduces power by 6-7hp. Most of the power gains come from the IAT drop and substantial ignition timing bump.

Regards,
shiv

as long as it's a safe tune, then it's all

So it was a tune equivalent to stock? Because OE has his original file no? So to say this "stock" file made more power then the OE is just going under the assumption that the tune EAS used is in fact stock? Because it NOT the OPs actual stock file correct?

EAS coded the DME to factory specs with their Autologic diagnostic tool. Took 30min or so.

Thanks for the clarification, can't wait to see a more moddified car with water/meth.
