For those who have an EGR delete, was the throttle butterfly left fitted or removed? Also, do you know if the remap only prevented the EGR valve from opening during engine running or were fuelling tweaks included?

My car was left unmolested except for an egr blanking plate. Mine also had a power boost remap as well as egr delete because why not

I cannot say what they do to remove the egr from the map, but know they do something to stop the errors popping up if blanked. I was told the map does stop the egr from operating so the blanking plate isn’t necessarily needed… but decided to get one fitted just in cast the egr was gunked up and not properly closed. Maybe unnecessary, but no harm and simple to remove. Currently driving: 2012 L322 SE Overfinch 4.4 tdv8

Does anyone know of (anyone) who makes a map that can be uploaded with the Gap IID tool?
I seem to recall I've read about that being possible with other models/engines.

How "strong" is map sensor? Is it possible to damage it when cleaning with compressed air for example?

It would throw a fault code if damaged as the ECU would know if a pressure reading was outside expected parameters for RPM, load etc and it throws a code if disconnected straight away. 2012 TDV8 Vogue (L322)

Thanks FFRR-lover for your comments - much appreciated.

I found a local tuner who will do the re-map of an evening to get the updated map from the UK while I wait. He recommends the economy upgrade which brings the power and torque specs to about the same as the L405 4.4 for the same price, which I've decided to get. The ecu has to be bench-updated.
I'll install a blanking plate in case of future valve leakage once I'm happy with the update and at the same time will remove the section of pipe protruding into the airstream.

I’m curious… if the diaphragm was damaged, would the car know? Would it generate an alert?

I’ve only ever used a cleaning spray on mine at least… but who knows from a previous owner?

No DPF on mine but possibly on any vehicle that ended-up here that was built for another country.

@Telly-addict and @Ffrr-lover have you guys looked at exhaust gas temperature sensors readings after EGR-delete? Especially B1S2 and B1S3. Would be valuable information. I have pulled lots of data from my properly working OEM system for comparsion. Would be very interesting. I'm planning on deleting EGR too to improve engine health and longevity.

I can't say I have no. I'll try and have a look when I next get the chance but I'm pretty tied up with customer cars atm. Cam

Thanks, would be great 🙂

Mine had its EGR mapped out coupled with an economy tune supposedly taking power to a little over 250kW this evening. First impressions are that it is nicely responsive off the mark, upshifts occur on less throttle and at lower revs and it still idles through mud at 1000 rpm in either normal or GGS just as it did before as far as I can tell. Economy around the streets is improved and 100 kph cruising in undulating terrain might have improved a little, but I look forward to longer term usage.

@GraemeS same request to you then. If you have an IIDTool or any other interface for reading live values, maybe you can pull live data from exhaust temp sensors say at highway cruising speeds, now after EGR delete?

The only exhaust system temperature sensor on mine, which doesn't have a DPF, is in the left manifold and it doesn't work. The temp sensor in the EGR valve won't get any recirculated exhaust gases.

Oh, sorry, didn't know the system build-up for non-DPF vehicle. So you don't have any temp. sensors directly before or after the catalytic converter?
