racelogic traction control

[cerber]

with this system it can cut the injectors by sequence so it don't cut the same injector every time
it's look safe for the motor

[cerber]

someone know where i can take the rpm signal?
i don t know if the ecu have one output for the rpm signal
have you somes pics of the sensor brackets?
thanks

This guy seems to know a lot about the MBE

Hi Simon,
be good if you could keep updating this thread with your progress and findings.

Are you not going to use the trigger wheels on the rear wheels to determine wheel spin or is the rpm in addition to the trigger wheels.

[cerber]

yes i can update the thread when i get more information
the traction control need the motor rpm in addition of the speed wheel sensors

[m4tti]

The crank sensor is in the bell housing, with a trigger wheel behind the fly.

[cerber]

ok thanks but i need it in rpm
i think it s the pin 33 of the ecu (tacho signal)
and the pin 15 of the 24 way interface connector

[m4tti]

Pin 33 is what's quoted in the varley manual.

is GV manual is Tuscan II ?

[m4tti]

No. Good point it's sagaris. Which I presume on the ecu would be the same, but couldn't guarantee it. The fuse board in the tuscan 1 for example definitely has differences.

[cerber]

the ecu is the same it s the mbe 941
and the pinout here http://www.sbdev.co.uk/Info_sheets/MBE/941-970%20P...
so the pin 33 looks ok

[Walford]

Do you have the pinouts for the dash

[cerber]

no i dont have the pinout for the dash
but i think the 24 way connector com on the dash
and i have the pinout here

Sorry I haven't replied to your mail, I was hoping to take some pics of the brackets for you but haven't had a chance.

Front brackets are L shaped and screw to the front up rights and point to the back of the wheel studs on the hubs. So 5 counts on the front wheels each.

Rear right hand side uses the wheel speed sensor bracket which is drilled to take the new TC sensor just below the original speedo sensor. Both sensors JUST fit on the one bracket. Rear left bracket is a reflection of the rear right and bolts to the diff rear cover and the sensor points to the left toothed wheel.

I picked the RPM signal up from the engine wiring loom main plug, it's in the passenger footwell, the Cerbera wiring diagrams will show you which wire it is.

As your diagram above the system cuts a different injector each time but always by more than 50% so theres never a chance of a lean mix misfire causing any damage.

I made up a wiring loom which plugged in at the injectors so if there was any problems I could easily unplug and re-plug in the original loom easily.

I'll try and get some pics up this weekend.

Rich.

Hi Simon,
I know the cost would almost be double, but have you considered just going to Syvecs engine management. You'll get traction control along with a bunch of other features like knock sensing?

[Walford]

Was talk some time ago about Emerald doing plug in and play modern ECU
think they did AJP8

[cerber]

Thanks booster cerb for your answer
And if you have time to take pics of the front bracket
I have take a look on my car and i think i need drill the side of the front hub for fix the bracket?
I don't have a lot of Space

I think the syvecs ECU or the new mbe can be a good improvement but you need time for do the new fuel map on the ECU and it isn't cheap
And i am in France so the racelogic looks the best solution for me now
