Sounds like a clean bill of health for your electrical system. How dd the tune file get corrupted though? I imagine it must have been on some sort of (Solid State??) Drive and maybe some of the sectors went bad??
Yes good news on the electrics! Phew. I was hoping they could tell me hope the file got corrupted after 3 years of use. They said it was getting hot so maybe the hot weather has some impact? anyway I'll fit the ECU and see if the performance and driving is drastically different.
Glad the puzzle has been solved Way to go!!! Your flip could have caused the ECU brain damage. :wink:
hahaha yes maybe the ECU does not like being rolled. On the plus side I'm pretty sure under the rally conditions and hot weather the engine would have been fried with that bad fuel. So all worked out in the end.
I wonder if it was one of the rally monkeys? Like maybe the rally monkey came by and tried to extract some of the horsepower from the MINI....:idea: Blame the rally monkey
Yeah, tunes can do weird things... Back in the day, I loaded an RMW tune over an MTH tune, and some weird things resulted, until Jan redid everything starting with a stock tune. Took 3 years to find that issue and fix it...
I'm sure there's going to be a difference. The programing can change a lot with this engine. I never thought to investigate what it is exactly but when we bought our Mini it came equipped with some performance gimmick that has a switch button. If i press it once the switch turns green and the car accelerates a lot quicker. If i press it for the second time the button turns red and the engine picks up so fast the rpm needle gets in the red in what seems like an eyeblink. I use it sparingly because i want the car to last but sometimes if some other driver is a dick because they think they can out accelerate me i kindly unconfuse them about it.
That's called a Sprint Booster. It does nothing to the tune or the programming of the engine per se. It just plugs into your accelerator pedal and changes the output curve of the pedal. Some folks claim it just mimics pressing the pedal faster, but not exactly. It DOES vastly improve the "feel" of throttle response in cars with electronic throttles and conservatively mapped pedal response. Tuners like RMW can adjust the throttle response curve in the actual tune, and make this unnecessary. I put one on my BMW E90 328i to make the pedal response feel more like that of my RMW tuned MINI, and I can't live without it.
So I called the ECU guy to see what corrupted the tune file. He was pretty vague with the answers. Saying mostly it could be a voltage thing when the file was up-loaded or some other voltage error within the ECU or a sensor feeding the info to the ECU. He said we see this as a common fault but don't really know what causes it. We replace the faulty chips, re-load the file and this cures it. Which leaves the cause pretty much wide open! Seeing as I replaced all the sensors I'm hoping the fault does not return.
I never worked on no ECM but i do have some experience with computers and i don't see how input from sensors could corrupt the file, and if was not uploaded correctly why did it take that long to develop symptoms? The voltage error within the ECU sounds plausible to an extend. Good think you have the warranty. But i wouldn't worry to much.
Drum roll, trumpets ! Plug n pray. Bummer P1656 error code! The engine turns over but will not start. EWS/EMC error
