I know what you mean.....and I've had that relationship with my bmw dealership but I'm not there with my local lotus service center

That's cool but I'm pretty sure every dealership will tell you how not to get claims rejected....it'll be a resounding " don't move away from oem"

I would hope any tuner, including piggyback developers, would measure injector flow rates....increase boost, increases air which in turn increases the need for more fuel. Not enough fuel causes lean conditions and eventually problems including the fuel pump, quite linear...but you guys prolly...

So you removed the TDI and replaced with JB4? Did you loosen AC compressor belt to get that difficult sensor?

v6 and i4 at your disposal and you don't line them up? I'm not buying it. It's my read they liked the i4 more than expected BUT will lean towards their own book. Always love their perspective but the conflict pops for me.

I get poor reception as well....

August

That's exactly what's happening....all my M cars did this and my emira every now and then.....at wot the dct on the emira is excellent but any other input it's lazy. Slurs into gears and just not visceral. This car is in dire need of tcm tune.

Could be.....

Looks good but need to make sure moisture doesn't get to it.....I've been down that road.

You can see a bit of the champagne color with the lighting.....photos don't capture how deep and striking this color is in person. That said, surface shaping for this car is the win.

Per TDI instruction they mention loosening the AC compressor to access that sensor.....

Mine does exactly that.....going in next week with a couple of other things

Any issue with R, N, 1 selections?

Either they don't recognize their competition or don't care.....i would expect to pay that for full ecu tune.

Well here comes the first stupid question.....even though 0-60 times were similar box vs no box, did the torque come in a bit harder or earlier?

burger could figure out if you have obd plugged in....if not, could be faulty piggybox.

....and I wish I could buy you a beer!! Looking forward to your performance comments. It looks as if TDI instructions have you move ac compressor to get to that difficult sensor.🤔

Hi, this may have been covered....is there a bracket for the I4 or one in the same?

Positive impression for me....installed today, flutter remains and big pssssh when coming off boost. I'm like a one man band driving around and loving it. This may also be placebo but I've noticed a positive up tick in throttle response. I'm going for the jb4!

FYI.... Directly from GFB Tech Dept. help you with? Hi, Purchased this bov and excited to get it installed. Is the item dialed in from factory at correct setting or do I need to adjust screw for optimal performance. Thanks Ray Hi Ray, There is no adjustment to be done on that valve. The...

Spoke with lotus engineering about that.....very few turbo cars across the country are experiencing the casting sand in coolant. Those that have, however, are having a tough go of it.

See if you can test drive both....once you go WOT in track mode in the I4, you're decision will be made.....

Not sure if it's the turbo's exhaust note that's superior to the 6 or the myriad of other noises that come with it....waste gate, turbo flutter, bov, plus the exhaust whack you get on wot going through the gears.....a lot of theater imo.

I believe i hear the flutter on Kaz's video although rock n roll has killed my ears

My kingdom for an I4 jb4 review!!

Great suggestions above and would also add that you pull the VIN for full details on work completed PRIOR to purchase.

Is the owner of the blue turbo on here? If so, can you comment on the performance?

Hey Was your car the blue i4 at bms? Curious what your thoughts are with the jb4

I think I'm going to do just that......problem is there fetching 10-15k over, my ego won't allow it!

Louder than oem? Worthy mod?

Hi, did you make that yourself?

Thank you for this! Really cool touch

excellent report of findings Doc! Curious how/if throttle response is improved? Have been looking for throttle controller but none exist for Emira. I'm assuming an intake will assist with that.

looking forward to your build...

Right around break in, 1000k or so. A metallic sound, correct?....maybe there was a software update for that...lol. I'd go and push around the door card and adjacent panels.....make sure seat belt clip isn't banging around. I was getting a noise behind my head where headliner meets rear...

I did, in an I4 .....then it mysterious disappeared

If I go with piggy, I believe I'll choose jb4....they've been great in the past. Side note.....I was doing full throttle runs in track mode last night and I can't believe the sounds coming from the blowoff valve and waste gate.....a piggyback and updated bov would make the turbo exceptional!

Actually that was the exact opposite of my experience with the two brands. I'd advise to call yourself and get those questions answered.
