What, they were going to charge $974 USD for shipping alone over quoting $102 USD originally?

Sweet as. What are after for one of those ADC boards?

They sound like they would suit. However I think the other requirement is the output as a digital from analogue input to be set to the right pulse rate, so it would need to be calibrated as such with some on road testing. I believe the original gear driven hall effect sensor was 32 pulse per full rotation of the tail shaft vs 4 pulses of the VR sensor, so given that its not as simple as a direct ADC. This is why I've looked to use the Arduino. I once got a similar driver 2 years ago for another project but gave up because of not being familiar with the coding. I shall persist this time!

Yeah, a hall effect output is what the ECU needs to regulate the dash and some other units. I thought this would be an issue looking at the wiring diagrams and sure enough it is. This board runs a ATmega328P chip. The original hall effect sensor, 3 wire type 5v + / Signal / GND, runs a gear setup at the back of the gearbox, it gives the siginal as a 0 (low) and 5v (high reading) to the ECU and Dash. On the otherside of the box theres the VR sensor

Will look into those today Troy. Thanks! It's one of these kind of inductive sensors I wish to use as the input http://cdn2.stylincdn.com/is/image/Autos/sisc281_is?$700x700$ James, I need an square wave signal 0-5v that runs back to the dash, this is for the ECU. What is involved with using such ICs like you suggest?

Thanks for the tip Troy, wasn't aware those! One code I've found that does more along the lines of what I want is this, but it outputs to the serial display, I want to try get that as an digitial out put instead. */ // the setup routine runs once when you press reset: void setup() { // initialize serial communication at 9600 bits per second: Serial.begin(9600); } // the loop routine runs over and over again forever: void loop() { // read the input on analog pin 0: int sensorValue = analogRead(A0); // Convert the analog reading (which goes from 0 - 1023) to a voltage (0 - 5V): float voltage = sensorValue * (5.0 / 1023.0); // print out the value you read: Serial.println(voltage); }

Hey guys, Just wondered if there was anyone here up to speed on using Arduino gear & the coding? I need a fairly simple solution to a speedo signal problem. To keep it simple, I need to input a 2 wire magnetic speed sensor as an analogue input to the Arduino unit, for it to be coded to act as an analogue to digital (ADC) converter, giving the digital output as 0-5v, giving the high reading for each pulse, then I can use that signal for the ECU. The 2 wire speed sensor does 4 pulses per rpm of the trans output shaft. The original 3 wire hall effect sensor is gone since I changed the gearbox with a different model on the weekend. Any help would be great!

Looks very good. If the mechanicals check out, that would be a good buy. Condition over kms!

Looks great. Is it an M62 or M90 charger?

Is that a genuine Aplina? It does strike me as a somewhat strange combination with the manual gearbox. Pity it dosen't make a good noise either.

Seeing this replicated really does show how foolish BMW was to NOT put it into production.

Tell me more - what cars could tell you the hours run?

Very good. Meanwhile how is the driveway & front bumper situation going?

What if they were mostly motorway KMs? You'd miss out on a good car haha. As I always say, condition & service history comes before mileage.

If the tester is from Germany he is probably used to doing tests in BMW 3 series models. Another day at the office

Ouch, what was the circumstance of the dog incident?

Did you have to factor in any correction with a thicker headgasket having the heads skimmed? From what I know adjusting thickness actually alters the cam chain timing unless its compensated for.

Subtle add-ons but make such a change, your old signature pic shows that with the absent front lip!

Replaced the Vanos oil line that was leaking.

Do one in an M coupe Ray. Perfection!

Ha, Déjà vu? We had another like this crashed earlier in the year right?

Is the S62 one of the all time best engines?

That fabric roof though.

So the 850i must be the Holden Monaro coupe of Germany

Mmm yeah I like the early M60 and M62 dual chain, just less interested in the single chain type
