Quick question, on the logs with the pedal at 100 and the rpm's climbing (1st log right away almost and second in the middle) why does the trottle drop out so hard and then come back during the pull? I have noticed this sometimes on my car and just curious as the car doesnt seem to slow why does it do it?

Hey terry if all I have access to is 91 octane, can I still up it to +4 on the Stage 1, or should I only up it to +4 if I have 93 or some e85 mix to up the octane?

Also there are spy photo's and blogs about the X1/X3 20i as well as (don't laugh) the 420i. That's one car I would not de-badge. Not sure if the US would get the 420i due to the price point and lack of ponies but this N20B doesn't seem to be going anywhere soon. **'s would help this car out a lot. Terry has already pulled more then 30 percent more power out of our shop car with just tuning alone.

They are scrapping it in favor of the B48 (currently in the 2014 mini cooper s).

Sorry for the late question, but I thought it'd be better answered here. What octane was run in these dynos? Hoping to hear the Stage2 run was 93 octane or something....

The 320 likes E85. Start with a 30-40% mix.

Ok, so just picked one of these up as a work car to put mileage on. It looks like there is one map specifically for the 320. What is the advantage to getting the JB4 if I'm not looking to do any additional tuning? Does the stage 1 include EWG control etc? I do want it to drive as smoothly as possible. But not looking to go full tilt like I have on my 435.

Hi Terry,

Any updates on the N20 for the 320i yet?
You mentioned about trying to hit high 11's for the AFR's.. is it possible to be done just with the JB4 alone with the flexfuel wires? Or are you potentially looking at new injectors?

Would love to be able to hit those richer AFR's, then maybe that could unlock the potential to run on Map2 with 22-23psi boost..

260whp compares to approximately how much "manufacturer claimed HP" at the crank? I think I saw a dyno graph where the stock 328i made 230whp for 240hp claimed. Is there a formula or is 275hp a good guess based on the comparisons?

How come 320i gets whp=hp on this dyno test?

No the 320i runs in the high 13s.

Looks +3psi is a bit better than +4psi? For +4 the peak torque 250 is on 2800rpm. It's not very useful for an AT car because of kick down. Map5 17psi looks similar, peak torque on low rpm. From 2000 to 5000 rpm map5 keeps around 250 torque while +3 or +4 psi has about 230-240 torque. For daily drive the difference between 17psi and +3psi is not obvious. Maybe I should lower the boost to +3psi using map6 for daily drive, and use map5 in more aggressive situation. Is it a good practice?

The knock problem finally it's fuel problem. In Shanghai the highest is RON 98 and it's hard to find. So I was using Ron 95+MMT and knock. Recently nearby gas station supplies RON98, now map5 is working with 20i.

Gscale,
I've been running with RON97 and Map1 since i swapped out my stock ** with a ******* one. However, I set the boost safety to 21psi.... not had any problems since... i'm currently trying out Map2 with boost safety at 23psi....

Yes, 8at won't have any problem, I believe. 8at wont let rpm below 3000 when WOT at any gear(except gear 1). For 6mt, I need to carefully choose gear before WOT. When RON95, it's very difficult to avoid knock, such as gear 3 below 3000 rpm. When RON98, it's much easier to handle.

Hi Terry

Have you made a new Dyno test for the 320i with the B48 engine?

Hello terry and guys. Need your advise.
Currently my setup is jb4 without the ff and ewg wire(ordered waiting for it to arrive).
******* ******** with full exhaust system. On the current map3 (which is additive +6psi) only manage to get 230whp on dyno. Care to share how do u get that figure. And what are your user adjustments setting for jb4. Thanks terry and guys.

Default 320i N20 w/ Methanol Injection - 06-21-2018, 12:09 PM

Hi All - I hit the dyno in the 320i w/ Meth. Huge thank you to Ando @ Burger, he has been tremendous to work with on reviewing logs and overall support of the many questions I had.

Also, dynoing a car in Chicago is damn near impossible. Josh, ***hy, and Chris were all a pleasure to work with at P&L Motorsports (Subaru WRX shop). Very knowledgeable, and they were able to support my exact dyno plan in a quick hour over lunch. From setup to multiple runs on different JB4 maps, it was quick and efficient all from my iPad and the JB4 Connect Kit.

Car Details:
Model: 320i, RWD
Engine: N20
Intake: AFE Momentum
Turbo: OEM
Plumbing: ER Turbo to Intercooler & Chargepipe
Intercooler: VRSF Street
EDP: OEM
Exhaust: AWE w/ Mid-pipe
Tune: JB4
Meth Kit: Burger Tuning w/ CM7 Nozzle (Stealth Tank, Pump, FSB, etc...). WMI Boost Additive Setting of "55"
Methanol: Boost Juice
Fuel: 30% E85 / 70% 93 Octane

I did 3 runs of each JB4 map to make sure results were accurate and repeatable.
Map 0 - JB4 Off
Map 5 - JB4 320i Autotuning Map
Map 3 - JB4 Methanol Map

The boost levels achieved on each map were the following:
Map 0 - 8lbs
Map 5 - 16lbs
Map 3 - 22lbs

HP / TQ Numbers (Wheel) were the following:
Map 0 - 191 / 189
Map 5 - 245 / 254
Map 3 - 270 / 291

Overall I'm happy with the car. With the 320i being stripped down and RWD, when it goes into "Meth mode" you can certainly feel it. Watching the IAT decrease in temp vs. increase is great too. I hope to move to a 340i in a couple of years, but where I'm at in life, I'm certainly happy with the gains.

Happy to answer any questions for anyone considering the installation. I think I was able to complete the install quite cleanly between the trunk and engine bay.
