I have a modified Mini R53 engine (aftermarket Thumper TPR2 head, TVS 900 supercharger and Schrick Cam) for which I recently had a G4+ installed. For reference, additionally to the ECU the following components were also installed prio to the tune: AEM X-Series Breitband UEGO AFR wideband controller 30-0300A CatCams 469 cam 550 injectors smaller SC pulley (60mm, coming from 70mm) The car was running fine with the OEM ECU and previous parts. The tune it got on the G4+ + having the new parts installed obviously helped it a lot and it is also running well overall and I am really happy so far, BUT the way the engine now comes back to idle after coming off the throttle is quite odd IMHO. IDLE Questions The following idle issues occur (please bear with me as I am firstly a noob to ECU tuning altogether and my technical/engineering background is limited - so basically some of the worst credentials to be doing a deep dive into this whole topic in general): When coming off higher engine loads (throttle position usually > 50% & always > 3,000 RPM) and letting the engine "run out" (throttle position = 0) idle rpm drops well under 1,000rpm and the engine almost dies/stalls (EML light shortrly lights up as when it stalls). It then feels like it tries to counteract that by reving up shortly with a short "blip" up to 2.000 rpm. The engine/ECU keeps doing that over and over again if I let it. When @ < 3,000rpms and laying off the thottle it only slightly dips under 1,000rpm and then also only slightly goes up as above but only once and only up to about 1.200rpm - and then is stops doing it (as opposed to the above described behaviour). With this I could live - the afore mentioned issue #1 is a real pain though... When in lower rpms (<3,000rpm) and during mellow driving / cruising and changing gears and as soon as I lay off the throttle, the rpms shortly "blip" up or hover before I change into another gear. I've tried looking at idle control but can't seem to find any anomalies. Could it be realted to the wideband sensor/controler? (.pclr file and log attached for reference) Knock Count question Also, I've gotten a global knock count of 10 on my last logged drive (including spirited revving up to the limiter) Is this something to worry about or can I disregard this? I'm told these knocks can be disregarded - if so, the only question is how can I tell when it's becoming critical? For me personally, any number > 5 in my global knock count after a short drive is critical or am I being to picky about it?

I just bought my i88, and its on it way to me. I have a couple questions about retaining some of the Factory Function of my MINI. I have the following features that I would love to retain: Chrono Pak GaugeAir ConCruise ControlI understand that the AirConditioning will still work with the auto Control setup (which is in my car), is this correct? Cruise Control - Is there a way to use the factory buttons on the Steering Wheel? Is there going to be an update that will make the Chrono Gauges work? The car is a full build: Block from the 2006 MINI Cooper SCrank – Factory (but machined and polished)RMW RodsRMW Pistons 77.5mmRMW Big Valve HeadRMW 450cc Injectors (aka Doge SRT4 Injectors)RMW Camshaft (Dominator)RMW Baffled Oil PanKing Race Main BearingsKing Race Rod BearingsATI Crank Damper17% WayMotorWorks Supercharger PulleyRMW Header (with Catalytic)JCW ExhaustGTT Stealth Cold Air IntakeAquaMist Water Methanol Injection SystemMC40 Style Gauge Mount (AquaMist Gauge/Controller & Boost Gauge)Wayland Shift Knob (thank the wife for this one)JCW SpringsJCW ShockR56 Rear Trailing Arms (GP style)R56 Front BrakesR56 Front Rotors Drilled & SlottedBBS/MINI R90 WheelsNM adjustable Lower Control ArmsHotchkis 22mm Hollow Rear Sawy BarPowerFlex Rear Bushings for the R56 Trailing ArmsPower Flex Front Lower Control Arm BushingsPower Flex Lower Engine Mount Bushing Also is there a special way to wire in the water/meth control to the ECU?

Hello, I have a G4 Plug-In (G4 Topboard Extreme, Firmware 4.10.2) for my 2003 MINI Cooper S, and I am setting up Knock Control. The diagram in PCLink Help labels Pin 8 as Knock 1, and it is the pin where the MINI Knock Sensor terminates. But when setting up Knock Control the only option is ON - DI Knk Interface. Is selecting ON - DI Knk Interface all I have to do? TIA Alan
