    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.

    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.

    Charming, the tech is away until next Monday so I'll have to wait until then!! OMG excellent customer service.

    Looking online it seems my Chinese Amazon cable could be the problem. Seems the BMW's lads have the same issues and blame the poorly made cable and software. Mmmm as always you get what you paid for. I hope the rally dude in CR can come to the rescue.

    Hollywood has got nothing on real life !! You just couldn't make up all the ebb and flows of this thread. Once again best wishes on what hopefully is the final leg of your quest.

    A dramatic friend compared this sort of maddening shade tree (+) diagnostic work to being a blind boxer. Let me see if I can remember enough to do justice to his analogy.

    You feel your way around the ring searching for any clue where to swing (or swing next). You know your opponent is there, confined within the ring, but you don't know exactly where because you can't see him. Even when you think you have him located, you can't be certain but you have to take a swing anyway, just in case. When you get so close that he's standing right in front of you, you probably don't know it. You occasionally get a piece of him but only rarely and it's a glancing blow that has no significant effect. Very frustrating until you finally take a swing that makes real contact...assuming you have enough stamina to hold out until that finally happens...

    Like I said, he has a flair for the dramatic. Still, not far off...unfortunately.

    only they emailed me to be patient! Which after a month I think I have been. Wiring harness arrived. November is my Birthday month so I'm hoping for an early gift!

    The fun begins again! I got here lunch time on Saturday but any thoughts of working on the Mini Sunday were over when my checked bag didn't show up until Sunday! The bag was delivered in the afternoon so meanwhile I took off the old engine harness. The bag arrived so I compared my harness to the Ebay version.....drat they sent me an automatic harness!! checking the plugs of the new harness which has everything I have but 2 extra plugs which I presume are to the auto box. I traced the wires back to the round plug on the air filter box which has more pin than mine.

    I cut all the wires and removed plugs/wires and pins. The only other issue is the knock sensor I have has 2 wires , the new harness has 3. So I need to follow the wires and figure out how the fix it. When I bought the harness they said it was for a 2004 manual but having to wait another 4 weeks to return it and get the manual version is not something I want to do. Just another small set back which I'm getting used too!

    I'm thinking you need to start taking more of those siestas with mucha cerveza fria to help ease the pains of frustration. True, it won't solve your ongoing MINI problems, but asi es la vida. In the meantime, :fingerscrossed:

    Done a bit of online reading as it's raining buckets. One Mini owner had multiple Tmaps replaced finding out he was over oiling his K+N filter. Another owner replaced the engine harness and fixed the problem. So I'm going to buy another Tmap and see want happens.

    I really hope that this will be the fix. No one should have to go through this many ups and downs to repair a problem.

    Maybe the intake is leaking? I have disco fog machine so I might blow some fog through the intake pipe

    Thanks for the suggestions last night I tried the fog machine down the intake which didn't do much because the throttle butterfly is closed. So I pulled off the intake and sealed it off at the throttle body,then I blew down the valve cover pipe to listen for leaks but unfortunately there were none. Anyway not getting the voltage on #4 pin must have something to do with the issue so I thought about cutting the sensor ground wire to the ECU and run it directly to the chassis to see if the voltage appears to #4 pin, worse case is I would fry the sensor.

    Yes the problem started after the bad fuel but the engine runs way better than it did because the misfire was worse back then. Now the misfire just happens in a small rpm range.

    Maybe if you drive it for a while it'll correct itself now that you have the T-Map working properly. The ECU could still be trying to compensate for the erroneous readings you were getting before. Then again, I don't know that much about these cars. Maybe a new condenser and clean the points. :D

    Ah yes I wish I could change the points! LOL. At this moment I think I'm just pi$$ing in the wind

    If the Mini is not sick I am! Got a sinus infection which grounded me all week and Saturday but I braved it today. The clutch bearing seemed better today as I could get the gears.

    I took off the intake, sealed it up and tested it for leaks. I found nothing wrong. I did find the vacuum feed to the fuel pressure regulator blocked so I replaced the pipe with the hope this is the problem. Also I tested the fuel pressure again and all was well there, with vacuum on and off, I blocked off each of the pipes going the intake which didn't improve anything.

    So seeing the Mini has been nowhere since July and the clutch working I pulled the Tmap plug and went for a drive. Engine ran fine and pulled really well, I would not have guessed the Tmap was not plugged in. I filled up with fuel fitted the Tmap plug and kept the revs above 4000rpm to avoid the misfire. Going downhill all was well but coming back up the hill the misfire happened at 5500 so I presume the engine is more loaded causing the misfire? At least I got a drive today! Next I need to buy a vacuum tester to see what the intake pressure is up to.

    I changed the crank and cam sensor last month and ran the engine with the knock sensor plug off.

    Maybe I'm losing it but last night after re-fitting the plugs when I'd finished the compression test the fault seemed to take longer to appear, also the plugs were quite sooty around the prongs. Likewise with the pre-cat 02 sensor.

    I read last night some Mini owners had a faulty throttle body causing Tmap calculation issues. I have the old one in the shed so I'll fit that tonight.
