So basically still nothing for anyone who lives outside of China, and maybe soon the US. Australian owners stuck with a 360hp car or a piggyback. Bugger!

Now this is an ECU thing, we should see the exact same bhp from the 360hp cars.

If this has actually now happened. I'm in. The Lotus Emira supercar would finally be here.

Hey, no worries. I did have the P2270 (lean code) come up after I completely messed up a gear change, but that disappeared when the car was restarted, and that was just a one off. So far the spacer has done it job, and I haven't had to mess around with the spacer thickness. I only use one...

Mine was basically the opposite. PO420 'Catalyst System Efficiency Below Threshold Bank 1'.

I actually never noticed any decrease in power, just no pops and bangs..... which is definitely weird.

The warning light stops the pop and bangs. When I was getting the warning light from the new downpipe the pop and bangs stopped. I fitted 'eBay special' O2 sensor spacers, and now I don't get any codes and the pops and bangs are back.

Only this one at the moment. I'll do more videos come summer.

Ah sorry.... good old eBay!!! https://www.ebay.com.au/itm/276252733686

I have the GRP downpipe and exhaust. I am very pleased with the sound. No idea if its better or worse than others as I've not heard any other systems in 'real life' and you can never get the true sound on the computer.

How long is that mineral designed to last?

I realised I never updated this post. The O2 spacers work perfectly. No more throwing codes. The exhaust note is just getting better and better the more I use the car. Amazing.

Do Snowtech have a website?

That pipe has to be worth a few extra HP on its own.

wow.... that seems like a lot of hard work. Looking forward to seeing the gains.

But you can't fully build your own map???

Can we make our own adjustments, or run our own maps on the JB4?

Do you have any actual figures though? Have you timed the 0-60 since fitting?

Anyone with a 360bhp i4 fitted a JB4, and have any dyno runs done, or have any new performance data (such as 0-60 times)???

Hey. Do you have other parts in the same black pack colour??? Cheers

Agreed. I'd love to see a lot of these aftermarket body parts available finished in the Lotus Black Pack colour. Sometimes the carbon fibre just sticks out like a sore thumb.

Interested, if the design is right and its finished in the same colour as the black pack (saves having to get it finished locally).

I'm also interested in replacing the rear window with a carbon or fibreglass vent. I'd like to continue the black pack look from the roof so that the vent looks like it was done from factory. Hopefully more of these options will be available shortly.

Are you sure that's correct, as that's huge boost! You could pump your tyres up with that. Surely that kind of boost would give you close to 500HP.

Depends on your skills (as this piggyback has been fitted to hundreds or probably thousands of models of cars)... or the skills of someone else who wants to take a little project on. Anyway, the main point of the post was to ask what makes the JB4 so special with something like the DET3 being on...

It's not plug and play for the Emira. It's just a universal piggyback so it would need to be to be installed as a custom fit. So either cutting wires (obviously not ideal) or a harness would need to be made up. Currently out of my scope of skills (although I do have one of these piggybacks that...

But isn't that pretty much the same as this???: The DIGITAL ECU TUNER 3 is a very popular piggyback tuning device across Europe. The DET3 is probably the most capable piggyback tuning device for its size. The DET3 is incredibly versatile, user friendly and powerful. For most applications, the...

I'm not sure what's been cracked.... isn't it just a piggyback manipulating the factory ECU signals. Can't all piggybacks do this in some form?

What makes the JB4 better that a truely universal piggyback like the ECUMaster DET3?

Are these axle issues just a V6 specific thing?

'May' increase throttle response.... but mostly for sound really.

I definitely need to remove the enhanced sound from the speakers so I hear more the of real sound.

Hey. Does anyone have an image of the view out of the back window with that new louvre panel in place? Is there any view at all? I'm very tempted. Thanks

The GFB one that Greg sells will be a lot louder.

No CEL's or anything like that. Just a slightly louder, and a different kind of venting sound. It'll obviously sound different inside the car than outside. Those lucky pedestrians!

Why are you selling????..... JB4 :-)

I meant the comparison race between the stock i4 and v4. I've just updated the question. Cheers

Although, to be honest I expected way more power from the i4 with a tuning box. I don't have a clue how far these new style piggybacks can push things, but I've have similar power gains with 1.3 and 1.4 litre old school turbos with just a bleed valve!!!

I have one installed. It's not crazy loud like other valves, but it definitely adds more to the theatre. You literally don't know what to listen too!! hahah
