No boost after engine/turbo upgrade

[newsh]

Thanks mate, now get that phone on charge!
So it seems to me that when I did the ECU pin swap I should have also swapped pins 1 and 3 on the Hall sensor plug??

Cheers for the info lads. No further forward today, whipped off the dizzy, drilled out the pin on the gear wheel and removed and thats about it. I'll strip it down tomorrow in preparation for the Hall sender arriving.

On a plus not i did repack the wadding on my exhaust on my 2004 Aprilia Tuono. Sounds better now. Didn't sound quite right at high revs previously. Spot on at idle and then during the first half off the rev range but more than that it was missing the bassey twin rumble that i so enjoy. The packing blows out from the rear of the can forward and found about half of it missing.

Anyway thats totally off on a tangent but my news for the day none the less.

Glad the 5v i am seeing is correct. I've got high hopes for this hall sensor when it arrives. Hope my fault code is cured and that i can finally experience RS2 power in all its glory.

Dammit I can't do this **** on my phone

Edit- there we go, fixed!

No boost after engine/turbo upgrade

Both the same?

5v is correct. I mistakenly thought 12v
Had a look, it's fed from pin 12 of ECU on ABY

All irrelevant I guess if John's swap worked fine using his untouched 3B G40

From my 3b

Pin 1-pin 3 4.99volts
Pin 1-cam cover 5.02v

Pin1-Pin 2
0.11v Hall sensor window closed
4.88v Hall sensor window open

Mine was inverted from the info on SJM, mine was low voltage, then higher voltage at the window open.

Hall sensor is inverted ABY-3B

Sorry it should be 5V as its referenced from the ecu!

I seem to remember the hall sensor wiring is reversed on the 3B to ABY.

This is AAN (and ABY):





Easy enough to resolve the issue with absolute certainty with the harness connector disconnected from the G40 itself. by looking for continuity between either Pin 1 or Pin 3 and ground. Only the correct on will have continuity.

When you get a chance could you try a multimeter across the Dizzy 3 pin connector with ignition on. I'm intrigued to see would values you get? Perhaps this is my problem all along??

[newsh]

I didn't change any wiring at the hall sender when doing the pin swap on my 3B.

[gmac78]

Are we sure about 12v across across 3B Pin1 and Pin 3? I only get 4.99 with ignition on? Hmmm.....

[Error404]

I seem to remember the hall sensor wiring is reversed on the 3B to ABY.

ABY is +12v pin 1, ECU output pin 2, earth pin 3
3B is earth pin 1, ECU output pin 2, +12v pin 3

So perhaps the polarity of the sensor is the opposite of what the ABY ecu needs to see?
A suitable LED across pin 1 + 2 at the hall sensor connector would tell you if/how it is working

To check whether the hall sender is functioning you would need to remove the dizzy cap to observe the window in the rotor. Essentially they should be nearly 5V when the rotor covers the sender and 0V when the sender is exposed by the window in the rotor. The dizzy connector shoul have ground/earth on pin 1, 12V+ on pin 3 and the signal out from pin 2 to the ecu alternates between 5V and 0V. The values in the real world are close.
The ign will need to be on to get the measurement.

I stumbled upon this guide last night, just what i'm looking for, perfect! Bloody good forum this.
