Unlikely?

0-100 was 3.5s. It was a racechip with custom tuning for evaluation purpose.

That is a mechanical gauge, how could it be wrong? I am just saying stock is running 2 bars inline with what Lotus claims whereas JB4's data seems low.

We have 4 Emira waiting to get injectors replaced at the Guangzhou dealership. I dun want to get caught with injectors failure with a piggyback on so they can deny my warranty.

Have a track event at the end of month, I will wait after that, dun wanna have the injectors quit on me lol

That's strange, we hit 2.5 bar on another piggyback.

In that case, I guess we can throw that off even for consideration right?

I haven't heard of it but from what you described this piggyback could be even better than the JB4, so does it support the Emira?

They didn't crack the lock on ecu but the CANbus connection. Without CANBUS for logging, other piggyback will only up the boost just slightly for safety reason. JB4 is able to achieve higher boost because using log they are able to tell what the limit is for each individual car with it’s...

Without CANBUS for logging, other piggyback will only up the boost just slightly for safety reason. JB4 is able to achieve higher boost because using log they are able to tell what the limit is for each individual car with it’s different variables.

Depends on your fuel quality, IAT, AF , and among other variables, you might need to tweak a bit to run a higher map or not at all. This is why I keep telling everyone to start at the lowest map, log and check the data before you run a higher map. What works on someone else’s car doesn’t mean it...

Too bad you already left before the Lotus free track day and pool party, but no problem let me know next time you come and we will cook something up.

You can export it in an excel format, with numbers that are easier to read.

I have known more than 10 cars that got injector replaced by the dealers. One guy got rejected for injector warranty replacement because he had a BMC and a generic piggyback. I am still going to install a JB4 because I don't care paying out of my pocket if that happens.

Chill out man, like I said many times before I like JB4 from my previous experience and I have ordered one myself. I am just pointing out there are defective injectors cases out there, from what we have known in China has more than 10 cases, so giving a heads up to other owners to keep an eye on...

With more and more JB4 installed, I have a feeling more cases of defective injectors are going to surface, at least for the Turbo.

Please post your log data so we can compare.

Yes, I believe this is possible. You can do your custom tweaking by limited boost in certain rpm range. So let say you use map 3 or 4 for instant boost at lower rpm then cut the output in half once it is over 4k rpm or whatever you choose.

Milk242 (forum member) is going to Boomgear with me to pick up some parts this weekend. Maybe he can make some video of the parts they have.

I can ask my tuner (Boomgear) to place an order. PM me if interested.

But I like to point out once again, unlike many would believe a piggyback is undetectable by dealers or manufacturers, this is far from the truth. Modify at your own risk.

And Audi

Piggyback basically just fools the ecu into thinking it is under boost so it up the boost. What separates JB4 from others is the ability to run real time log through CANbus so it knows where the limit is, while other generic piggybacks will be running much conservative for safety reason, hence...

From my previous experience, they delivered, with wonderful customer service. I just ordered mine a few days ago and hopefully Boomgear can tweak it even further.

All modes.

Not the correct way to install a downpipe, there is no need to touch engine mounts nor the turbo, you can access the whole installation by removing the top cover and the service panel in the trunk. A proper downpipe will not throw any code at all, NONE! Mine was installed for more than 6 months...

For those of you who do not like CF or prefer oem style, a new version using metal and shapes like oem with curve is out. Slightly more expensive than the CF because it is a new mold for metal but it also feels much better than the CF pieces. If you already have MadTrace installed, you can just...

Btw, China has one of the strictest smog regulation in the world so most of you will sound even louder than mine above and more drama. We do not even have burbles and crackles from OE.

To really have any decent exhaust note for an i4, the most significant upgrade part is the downpipe. Different manufacturers have totally different output, we have tried more than a dozen downpipes and even HJS is no match to Mach5 that majority of Chinese owners are using; 200 cats, no cel...

Yup that's how mine got done, just from the service panel.

haha I will let him know

Probably SnowTech, my tuner Boomgear has been using it for more than 6 months in a few hundreds hot laps with good result. He is bringing his car with the Snowtech setup to Nurburgring for further testing.

That's what our experience is tracking in China for more than a year, I have been telling ppl here the potential risk but nobody really listen. If you track a lot, the safest approach is SS exhaust with heat shield, OBD value controller, and move the value motor to a cooler location.

Yeah still waiting to bring you to one of our local mountain drives!

To be honest, China's economy and its business owners do not rely on oversea markets as much as a lot of westerners believe they do. For instance, there are so many good quality aftermarket brands for brake calipers, suspension components, cooling components, CF stuff and etc that they focus...
