Useful source of Sensors?
Turbo Mini Forums

Thought this would be a handy topic, especially as i'm just looking at buying them all for my car

I'm going to be using an emerald ecu and so need:

1. Throttle position sensor
2. coolant sensor
3. air temp sensor
4. map sensor
5. lamba sensor
6. crank sensor

as the basic setup.

Now i was going to purchase 1-4 from emerald with prices being £25, £12, £12 and £70 plus the vat and postage.

Seem reasonable? I know that some are bosch sensors but i'm not sure what from. I have access to a trade acount at a bosch agent though so if someone has the numbers i may be able to do good deals on "sensor" packs as such

Sensor pack sounds good to me :)

Cosworth stuff is Magneti Marelli I believe?

The cosworth stuff is indeed all marelli.

The 2-bar map-sensors are good to around 16psi MAX i believe. The 2.5-bar (esc cos) are probably good for any of us, but there is of course the 3-bar stuff. If you can find them under £75 new, you're doing good.

Air-temp sensor - best one is the Rover Mems unit; the green one. It's a nice compact unit - a lot smaller than the Ford stuff! Get the plastic insert aswell- and you can use this as a nut, simply mounting the sensor in a piece of silicon hose after drilling/punching a hole through it!

Coolant & TPS - just go looking! Rover MEMS stuff is pretty good. Make sure you get a TPS with the sprung-loaded spindle.

Lambda - again, Rover MEMS are 4-wire Bosch, but don't pick peanuts out of poo here. Buy a new one!

Crank sensor - whatever you want! I've always found the Rover MEMS 2-wire ones highly reliable.

Suggest you speak to your engine management supplier first for the spec as there are many different resistances - so this is not a plug and play part. I found out the Intermotor numbers and went to the local motor factor but £10-12 is average for coolant/air temp

I stand corrected. You should know

Rover sensors are in the range that Emerald / DTA / Lumetion / etc work in...

and megasquirt. TPS, IAC, IAT, VR sensor all worked straight out the box.

Glad you popped up Evo!

Good work on the K-MS code BTW!

From DTA.....

THROTTLE POT

Almost any linear pot is fine preferable approx. 5KOhms

0280 122 201
Colvern or Jenvey pot
Ford 88WF9B989
Rover JZX3491

AIR TEMP SENSOR (ANY NTC READING APPROX. 2.4 KOHMS AT 20 DEG C)

Lucas SNB802
Bosch 0280 130 039

Water Temp Sensor (any NTC reading approx. 2.4 KOhms at 20 deg C)

Lucas SNB801
Bosch 0280 013 026

Crank Sensor (almost any VR (Magnetic) type)

Ford 6859702
6181945
Vx/Opel 904 514 41
Bosch 0261 210 036
0261 210 104
0261 210 001
0261 210 081 (VW)
Rover NSC100390

Lambda Sensor the following are recommended others will work

Bosch 0258 104 002
0258 006 127 (EU3)
NTK TL-7111-W1 (with amplifier TC600) P8 only

IGNITION COILS

Ford 6503280 (4 Cyl 4 ms coil on time)
Valeo V245041 (4 Cyl 3 ms coil on time)
Bosch 0221 503 407 (3 ms coil on time)
Bosch 0221 503 001 (3 ms coil on time)
Bosch 0221 503 002 (6 Cyl 3ms coil on time)
Distributor Coil 0221 118 322 (2 ms coil on time)

SINGLE IGNITION COILS

A word of warning about these. They are generally not chosen by manufacturers for performance reasons but usually some other. Just because they are fashionable, do not assume that they are better!

Audi 06B 905 115 S3 (amplified, pin 4 secondary earth, 3 signal, 2 primary earth, 1 12V, needs 2.2K pull up, coil on time ?)

ALS AND IDLE VALVE

Bosch 0280 140 512 (note this is very large for an idle valve and benefits from restriction)

Manifold and Barometric pressure (any 5 volt linear sensor will be fine)

Marelli APS05/01 (3.0 Bar)
Marelli PRT03/01 (1.15 Bar)

Turbo Control Valve

VW 0589 062 83F

Injectors (any resistance greater than 5 Ohms or described as direct switching, subject to the current rating of the ECU outputs)

Bosch 0280 150 803
Bosch 0280 150 744
Weber Pico Pico330/Pico440

Whilst you put it into the words of tech, I stand by what i said with my simplified speak.

The Rover sensors ARE suitable. I couldn't use any of the sensors when i removed my Weber Alpha for DTa back in 2001/2 either - and didn't want to. I wanted some sensors i could get from a breakers yard -not paying through the nose for Webcon prices.

I've yet to find a throttle-pot (other than the crappy bosch 'switched' type) that isn't 5K.
Also - If you pick up any senor off almost any Multi-point injection engine that isn't running a Bosch or Weber-based ECU (eg, BMW) it'll likely be fine - but a quick check is easy to do. The resistance doesn't change that much with +- 10 degrees of temp.

I've also been using a Sagem ignition coil, with no problems at all for 5 years. Again - not listed in the DTA 'specs' but entirely suitable.

The only MAP sensors to use are the Marelli ones. Thankfully - as these dfo vary greatly between different OEM's.

Hi,
The emerald system is plug and play for the Rover K series, so you can use any sensors off that engine with no problem.... However, you map sensor needs to be spot on, changing from the marelli low pressure to high pressure completly screws up fuelling!! Please let me know how you get on with the Emerald system as thats one of my possibles...
Cheers,
Gavin. :)

My Mini build diary

Agree about the Map sensor - when i switched from a 2-bar to a 3-bar it took a good few minutes scribbling on a piece of paper before i gave up and just imported the data into excell and did it that way! LOL!

Bat, I use the emerald ECU on my mini turbo, although igntion only at the moment, it works great, no problems at all.
