Would be very interested to hear your results on the piggyback tune as this is what I have been trying to find for mine ( also with the sports cat fitted)
The truth is, there's none yet.
Very interested to see how the piggyback tune goes.Just intalled the downpipe and drove back home. Haven't really pushed but slightly reved a little.
Quick thoughts: faster throttle response, obviously more torque now (the torque meter clocked to 430NM very early and obviously it's more than the frozen 430NM, I would say 480NM is quite a fair number now.)
It's a proper beast now, sound is better roar if not wild. So far no CEL and no smell, but will see if it can sustain a 15mins sprint mountain run in the weekend, even the stock condition will have CEL if run it hot enough.
Happily, in the tour mode the sound difference is negligable, because it's my wife's daily shopping car...
Conclusion: satisfaction!
Next: will do a piggyback tuning after my tuner sort out the cable connection part modifications.
If pops and bangs disappeared after CEL is on, I'd say the power might be detuned a little bit.
Just to give you a heads up there are over 10 cars that have defective injectors here in China, and if you get caught using a piggyback, warranty will be declined to replace the injector by Lotus England. All warranty claims have to go through Lotus England to get approval and the local dealer has to provide a full diagnostic test. One of my friends got rejected for the injector warranty claim for his CAI and piggyback which he had them replaced before the warranty claim and still dealer was able to find out from a full diagnostic test, so he ended up paying full price for a new one.Just intalled the downpipe and drove back home.

Downpipe that triggers CEL will not detune power, however exhaust that triggers CEL will detune power because most likely it is related to the value mechanism and the software is very strict on it. What brand of downpipe and exhaust did you get?
I went with GRP for both downpipe and exhaust. I'm extremely happy with the sound, it's mad. Just need to work around the CEL.
I am amazed Lotus approve any warranty work that they can potentially lay at the feet of an after market modification.
Is defective injectors very common in Emira now? Is that fuel quality related or just simply the product defection?
The exhaust valve is super sensitive on the I4 Emira. After I had my exhaust valve recalibrated (Ti Aerie Exhaust and Aerie Spirts Cat), I’ve not had any more CEL. It also seemed to sound better too.
Could you elaborate on the recalibration effort? what was done, and by whom; dealer/independent?
So I'll need to take the car to Lotus to have this done? No other way around it????
To calibrate it, you’ll need to go to Lotus. However, the Milltek valve control may solve the issue, as it will avoid the ECU getting any more errors. You should also be able to clear the CEL with an OBD tool.
@Andy H did you see post below?
Upgraded Intercooler
An upgraded intercooler helps a great deal, intake temperature cuts in half from 80 to less than 40, outside temperature is around 35 degree. .www.emiraforum.com
A new intercooler will reduce the heat and with a JUBU rear window swap the power could go as high as the A45S.
I have the Milltek controller already!
More than ten were known from our little owner circle and I suspect more are in the wild. Not fuel quality related, most owners pump BP 98ron, and since dealers replaced it for owners who do not mod, its obvious a product defection.
There is a tool who will stop any CEL from flashing but only for V6. Your CEL, if associated with the value mechanism, might detune your power and you don't want to get it hidden.
That should work
