    Motronic expert needed

    Now sorted. Old Oem ICV was tested cleaned and refitted. Now idle’s like a dream. The new one is going back, as you say, utter rubbish. thanks

    Motronic expert needed

    Ok, I have the old idle control valve so could swap over. It definitely feels like there is too much metered air getting in as it runs very smooth, just too high. Especially as the throttle plate is new and definitely fully closed, so there isn’t any air getting past that, the only other route will be the icv or the bleed in the air flow meter for CO setting (but that is close to closed). If I force the idle speed lower by riding the clutch it sometimes stays around 1000rpm...odd thanks. ian

    Motronic expert needed

    Car is 535ise with Alpina cam and chip, Motronic 1.3 Problem - when warmed up the car wants to idle at 1200 rpm and is eager off idle to say the least. Other than that it runs absolutely fine. here is what I have done but to no avail. 1. New TPS, adjusted and confirmed correct signals back to ecu plug for idle and WOT. 2. New CTS, tested back to ecu and shows correct 300 ohms when warm 3. New idle control valve - confirmed operating 4. No air leaks, new vacuum hoses, inlet gaskets etc. 5. Separately I had the throttle body bored out to 68mm, new spindle and throttle plate, fitted, adjusted to fully closed but still a high idle speed. It had a high idle speed before this was done. 6. I have an afr meter fitted (AEM) and idle air fuel ratio is set to 14.8 I know the Alpina chip raises the idle speed to 950-1000 rpm i also know that the ecu sets idle speed The ecu seems to be requesting a high idle speed (as if it thinks it is a cold engine?) even though the CTS is telling it that it is fully warm, and TPS is closed. i am running out of other things to check, unless you guys can suggest some other things to look at. thanks, Ian

    E34 Buyers Guide?

    I have recently restored a 535i se, loads spent on it which might put you off! But I can pm you the list of jobs and cost so you can get an idea of what things cost and what might need doing, mine was in very poor state when purchased and needed pretty much a full restoration. It will include the costly mods I have done too, which you should ignore, and no labour costs as apart from paint I do it all myself. best advice I could give is to buy the best you can, and with a good body, especially the sills, jacking points which are a pain in the Ass to rebuild. pm on its way to you. ian

    What have you done on your E34 Today

    Afraid I don’t have a project thread for it. I am on job 157 now with 4 left to do... 2 and a half years it took me but I do work away in the week. Biggest job was repairing/ replacing all 4 jacking points, weeks and weeks that job took. I’ll post a full list of “what I did to my e34 today” for the previous 700 odd days! Ps was your v8 engine knackered then?

    What have you done on your E34 Today

    It was fairly straight forward to do the engine, just a little expensive for the cam as it was brand new. Luckily I was able to re-use high compression pistons with new rings, the cam sprocket I slotted myself, engine rebuild was done by me, apart from machining work. A V8 install would be nice mind, maybe the next one I do...

    What have you done on your E34 Today

    Over the weekend I finally got my Alpina spec e34 mot’d. It passed! Recently had to change the block over due to oil in coolant issue, caused by cracks between the water jackets, oil gallery and head bolt hole in between cylinders 3 and 4. The M30 is such a heavy engine...big job but now done and back in the car. It’s now got 50 miles on it, runs very well and NO oil in coolanT. couple of pics below of the block rebuild. spec - Alpina cam, original Alpina ECU chip, slotted cam sprocket, high compression pistons, new rings, fritz bits complete exhaust system.

    E28 m5 timing chain

    Did this a number of years ago on my M635. it’s 2.5k if you do the chain sprockets and head refresh and get someone to do it. Parts for the chain only (that’s all parts - tensioner, crack sprocket guides etc) were about 850-900. You can do it without taking the head off if you are careful. Biggest problem is getting the crank nut off. It’s practically welded on it’s that tight. Big breaker bar and scaffold extension was needed. I did did mine at 152k miles. The chain was stretched and absolutely knackered. 2 rollers had actually fallen off. they do wear so at 139k miles it’s time to de-risk your engine.
