Totally agree, I will be pulling mine off late next month for my free dealer service. Hour and a half drive to Winston Salem is going to suck without the JB+, LOL...

 

I won't be planning an early retirement based on N18 tune sales but it has covered it's costs and pays for our MINI which myself and other BMS employees get to race around. So I'd say it's been a worthwhile endeavor.

We continue to play with possible higher stage tunes but so far have not hit upon the right mix of power gains over the JB+, cost, & ease of install to justify a higher Stage. But we'll continue to keep the gears turning there.

 

I would to hijack a gauge to see knock retard.

I ran a full tank of VP9 , 96 octane no ethanol
At about 90% with great power .

Be carefull of those running 108 plus etc , the
Cans state continued use or over use can ruin
Cats and O2 sensors.

But VP9 was $10 a gallon

 

That's why "we" don't have cats but I do recycle

Well on my 95 trans am it was dyno proven to
Take 2% power and considering its a federal
Law your messing with I never even considered
Running catless . Just not worth it.

 

no one said you can't take it off a block away from the dealer. =D my dealer is about 5 miles away when i pulled my JB+ to take it in for service, it was kinda sad how slow the car felt in comparison. as the saying goes, "don't know what you have 'til it's gone."

 

Can you offer a water/meth kit that costs less than the HFS-4 that runs off JB type hardware? Doesn't have to be a full blown JB4 if there isn't justification for that.

 

Well I took the plunge and decided to go from the default setting at 50% to the 2 o clock position(70%) and see how it'll go. I'm gonna take it a little slow at first to check A/F and stuff. I look forward to seeing boost a little higher than 16 that I was seeing.

 

Better/ newer options for water/meth kits would be great! And even better if it were designed specifically to work with the jb. Not sure how that will work, but it would definitely be a big hit!

 

Out of curiosity, what's the highest boost anyone has seen with the JB+ @ 100 and what was the ambient temp.?

I ask because when the weather starts to warm up, boost will as well. Boost cut on MCS is 22psi.

 

It showed up at 21psi at 50F outside. Big intercooler and no cats

One potential benefit would be a fully integrated tune/meth kit. Where the tune IS the meth controller so there are no extra wires to route, etc. But overall I'm not sure what demand would be. How many of you run meth kits currently?

 

I will and want to.

OK, per Terry I tried running a higher blend of e85. Here are my reads..

Dial 60%, WOT - boost 16-17, timing 2.5, afr 12.3-12.5:1

I had power full range of the rpm, no flattening out at the top end after 4500 rpm.

I would like to know... If I run colder plugs, will that help with the timing and combustion? and if I run 40% e85 all the time will I have any issues with sensors, hoses or anything else?

So overall with my car (2013), 100% 91 octane, I have to set the JB+ at 40% and if I run 40%-60% e85/91 I have to set the JB+ to 60%.

oh...forgot to add. Temp was 75deg.

 

I was about to pull the trigger on a snow performance kit on a black Friday sale. Opted to just wait a bit longer. I've worked with snow kits on other cars and they are really good. I'm kinda glad I waited now seeing how there will possibly be a kit 100% perfect for the n18! Seems like you guys are seriously going to be running the market for tuning these n18's! And I love that! Have had my JB+ on the car for around 4k miles at the default setting and have had nothing but great experiences!!! Motor on burger! Motor on!

 

If more people get them it will be more widely accepted, similar to how well and fast the JB+ took off. People are realizing the carbon cleaning will become normal and many find that unacceptable. I would be more willing to fill a meth/water tank weekly than deal with 30% E85 fill-up (I don't have a JB+ or even an N18 so I don't have the choice).


With more demand will be more affordable meth kits too. I would do it just for the carbon purposes, not even the possible performance enhancement of running a "stronger" tune.

I needs to be priced right and needs to make noise on the forums, as well as work, and people will buy them up; as with any good mod (ie: pulley, RSB, non RFTs, etc)

 

I have plans to get the JCW ecu flash done on my car in about a week and currently have a JB installed. Will I need to adjust the JB at all? Car currently have a aftermarket intake, exhaust and Intercooler. Thanks

 

Yes that is a huge plus to the meth kit! Keeping the valves clean of all carbon! That is why I would like to get one sooner than later. i only have 13k miles on my '13 MCS. I just ordered a catch can to aid slightly in the carbon build up. But the meth will help an incredible amount to keep carbon off of my valves and head in general. Obviously I will look for more performance from it as well! Killing two birds with one insanely awesome product while putting a smile on my face and leaving others in the dust sounds like a great plan! Hahaha sl

 

I wanted an extra kick last night and it was short lived, I was pulled over 30 feet, from where I treat myself to Race Fuel. No ticket but no gas either :((. They said they have been out for a month

I'd be interested. Would it adjust the tune depending on if it's spraying or not (if you ran out, for example)?

 

dayam dude, someone was looking out for you! =)

 

I believe JCW's/GP's have a higher boost limit.


I'm curious if any S cars will experience boost cuts when the weather gets warmer. Especially with overboost on quick WOT transitions.

These cars have boost spikes at WOT shift WOT scenarios then taper down. But if you're at 21 psi and it spikes past 22, you'll hit a wall of slowness lol.

 

I'm definitely looking for 18-19psi. I don't see why you would want to push the MCS too hard when Gab's R55 blew up his engine at 20-21psi lol. But hey more power to those who can get their engine to handle the power from the JB.

What's the highest someone has seen without boost spiking?

I can't wait for 70 degree weather to see how the car responds with 60% of 93 and 40% of E85.

 

Since I don't have E85 close to me, this is something that I would be interested in for sure!
