Burger Motorsports JB1 Tuning Module + Cable

[ringo]

Nice detailed description Ringo. I wondered how the over boost function might work with the JB1.

Was the Golf R stock or did it have a JB1 fitted too? The extra weight of the R would hold it back compared with the trim 40th, especially if it was stock.

R had just a resonator delete but otherwise stock. With my foot far away from the overboost switch and custom lower boost @4k rpm on map 6 (was actually out for testing, the run was completely unplanned) I reckon I must have hardly had 320ps at the time. The extra weight is negated imo from the fact that starting from as low as 20km/h and especially 1st gear, I had to battle wheel-spin (during the 1st run) while the R driver just floored it and launched forward and I wasn't going faster than him before 100km/h. On the 2nd attempt that I went easy on the throttle I managed to launch quicker, stay ahead and have an ever-growing gap to my favor.

If it was attempted from say 50-60km/h and 2nd gear I agree that I would have had a huge advantage as the car just instantly goes at anything at and above those speeds (which are of bigger real-life importance).

Launches and drag-races don't really concern me and I never do traffic light racing etc. the fact that run took place was merely down to the curiosity of the R driver (which was very impressed in the end). But it just shows that over-boost complicates things and needs to go.

Few conclusions and observations so far about the Clubsport + JB1 combo in particular:

I have experienced some non-linearity on both map 1 and 6 but only for a moment when I suddenly floor it. It's as if the car instantly hits some boost or torque threshold and holds back for a split sec before the revs continue to build up. If I go more progressively on the throttle it does not happen. No lights flash, this is not related with traction.

The Clubsport's over-boost function complicates things and hinders consistency. Sometimes it comes on sometimes it doesn't (I don't always remember to try and drill a hole with my right foot on the floor to activate it) so you don't always get the same amount of extra power. I've timed 60-160km/h accelerations with racing GPS device (no smartphone GPS) and I've seen some map 6 runs being almost identical to stock runs with the map 6 only winning maybe 0,5" at the upper end, while on others the JB1 shoves 1" off the stock time, all other conditions identical. That clearly shouldn't be the case if the car had gained a permanent 50-60bhp/100Nm across the entire range.

In a way, with the JB1 you ensure at least that you get the full stock power of 290ps+++ (more like 300-320) every time and if you always remember to bury your foot as hard as possible and are in 3rd gear and above you get close to the 350-360 mark. This is why you either need to code out the over-boost completely or use a piggyback that controls absolute pressure and makes up for the non-overboost situations, which is what the JB4 will hopefully be able to do.

Also, at least on stock Bridgestones, don't expect to bury your foot and go at anything below 60km/h, the torque overwhelms the tyres easily. Losing a few tenths and going easier up to 3rd gear works better. With that sort of modulation that might sound slow, I was ahead from a stock Golf R from a 20km/h 1st gear roll with the gap increasing (in my favor), and that was on map 6 and without over-boost activated (didn't even hit the kick-down switch). Considering that was 1st gear and I had to beware of the wheel-spin I was quite impressed. From the way it looked, if we rolled from 2nd 50/60km/h it wouldn't even come close.

All in all, I'm happy to have it on the car. Certainly gets the car to the next level of performance that coupled with the car's handling/cornering ability makes it impossible I think for almost any non-hyper exotic to escape from it on road or track. But, there are some complications to fully exploit it, that should be sorted with the coming JB4 upgrade and a set of better tyres.

Michelin PSS going on the car in 2 days time and the 034 dog mount in about 7-9days. I'll report back in the next couple of days on the difference the PSS makes to wheel spinning/hopping.

I'm still on Map1 coz I haven't had a chance to fiddle around with the map settings. Just out of curiosity, what Map6 settings are you on at the moment if you don't mind me asking?

Map 6 asks for less low end boost to begin with, and I've further dropped the boost at 4k rpm by half a psi after contact with BMS, to see if it cured the momentary hesitancy, but I don't think it did. It has to do more with how suddenly the throttle is requested than with specific rpm so I switched back to map 1 and will re-do those runs.

Still worth it at the regular price... Definitely!

I'm pretty sure it states that ignition should be on when connecting to the unit via the usb cable. As above, flat screwdriver and twist, super easy.

Switched mine to map 6 which runs lower low end boost and it seems to lack a little of that initial push back. However for an extra piece of mind and since I don't usually need all that low end torque I might keep it there.

One more thing, launch control with JB1 in this car is pointless unless probably if you run semi-slicks which have got up to temp. Tried it yesterday, and that was on the lower map 6, immediate smoke and stink of burned rubber while desperately trying to keep the wheel on a straight line. I know Potenzas have never really been up to the job but that was almost scary.

Not that I really bother with launches but I tend to try all my cars once or twice in that. Also, maybe the 3K rpm that the LC rises up to is too much, 1.5K seems a better option but I doubt I'll try it again until I switch tyres.

Needs more 4WD.

I've gotta say though - the launches with the JB1 in the R are ultra efficient, at the risk of being a little 'boring' since they're so undramatic! That said - less than 4 seconds 0-100 is certainly not boring for anyone in the passenger seat who's not used to it! Scared the life out of my girlfriend, haha.

Obviously, but I'm against the whole idea of launching 2/4/R/ wheel drive regardless. It feels (and probably is) brutal on the drivetrain, less challenging than shooting a paper ball in a bin and well... pointless really. A motorcycle can provide that sense of accelerating from standstill at a fraction of the cost and to a much more intense degree. I know for some, this will be as much of a "driving fun" as they are ever going to experience but to me it doesn't even classify as one.

Having experienced a few hard launches on 4WD, none of them even comes close to one flying lap around a track, neither in terms of challenge, thrill or satisfaction. Probably the reason that despite my love for motorsports I never understood (and that's being polite...) drag-racing.

JB1 Fitted love the power difference ... Fitted RAMAIR silicon hose and filter (btw recommend these guys highly cheaper than other filters but by price only quality is great) they will produce turbo intake in the next month or so. Happy overall I am on Map 1.

I hear ya, but no, the launches aren't as brutal as you might think. The DSG does a masterful job of providing enough slip to prevent drivetrain shock. It's more of a building rush, than a 'snap' of acceleration.

Totally agree about a flying lap of a racetrack - I've been to countless track days over the years, but never to the strip. In this day and age of DSG and traction control there's really not a lot of skill involved. That said some people enjoy it, and if that's their thing, so be it!

You talk about 'fun' on a racetrack - a FWD ain't really gods gift for enjoyment on a racetrack either. High powered RWD with no traction control has been my most enjoyable combination on-track! Blows everything else out of the water. Oversteer > Understeer

Sort of agree. What you are talking about: power oversteer and adjusting the tail with fine throttle inputs is surely fun, but more effective and ultimately faster? Not necessarily. I'm more of a time-attack guy so my idea of fun is how I can shove that extra tenth off my best time although my lap might not look that spectacular from the outside.

A well-balanced, sorted FWD with proper suspension, lsd and tyres that has a neutral-to-mild oversteer behaviour, can work (actually: has worked) wonders in embarrassing usually more powerful cars with either rear or all wheels driven when you look at best lap times at the end of the day.
