bmw e30 m50 swap dies when i give it gas
I have a problem when i give my e30 m50 about half throttle it stalls but when i let go off the throttle it runs good. I thought it was because i had no exhaust and the lambda was not pluggd in but today when i hade made my own exhaust i tried it but it was the same :? But i had a exhaust leak betwe...

Re: bmw e30 blower motor problems
WD40 is not going to lubricate the fan shaft for long, all it does is wash the old lubricant and crap out. Might free it up for a while, but it is not a permanent fix. I have never had much luck reviving my fans either, but at least you need to re-oil after the WD40. I have 2 fans, I stand the fan ...

Re: Bmw e30 m50swap tach problems
Aftermarket tacho. should work, as long as it's the type that will work on 'low' voltage pulses, rather than the type that picks up high voltage pulses from the ignition EHT. If you're measuring a varying voltage with engine revs on the black wire, then the ECU is probably OK. Can'y you borrow or b...

Re: Bmw e30 m50swap tach problems
If you're sure that the black wire is continuous, all the way from pin 47 of the ECU to pin 7 of the blue plug of the instrument cluster, and is not shorted out to another wire somewhere along the way, then either the ECU or the instrument cluster must be faulty. If you have access to such a tool, ...

Re: Bmw e30 m50swap tach problems
One of the two versions of the SI circuit board (which also hosts the tacho. circuitry) has two NiCd batteries on it, which provide memory power when the engine is off. These batteries have a limited lifespan, and when they fail, tend to go short circuit. The batteries may hang on for years in norm...

Re: Bmw e30 m50swap tach problems
SI leds = Service interval display - the 5 green LEDs + 1 amber + 1 red in the lower middle of the instrument cluster. I think I probably know the answer to your problem from the second answer you gave. An '86 E30 will probably have the tacho. signal (and fuel rate signal) going from the ECU to the...

Bmw e30 m50swap tach problems
My tach dont work but i have read online that it can be the coding plug but if its the coding plug thats wrong does the tach move at all or can it be dead because i have read that you need a new coding plug if the rpm dont read right but havent seen anything about the tach not move at all

Re: m50b25 vanos fuel but no spark
Today i got the head back from the machine shop and 5 valves was bend
But now that is fixed so the head is like brand new. And i think that it was the timing thats was off a little that caused it so im gonna correct it when i put it back togheter.

Re: m50b25 vanos fuel but no spark
If you suspect the valve stems are bent (thus causing lack of seal in the valve seat, and low compression), then they will have to be replaced. Find out what caused them to bend in the first place! If they aren't bent, then remove them and replace the valve guides and/or valve stem seals (if fitted...

That would normally be down to either a failed head gasket or extremely worn valve guides. Okey i have new head gasket so.
