Tdc sensor polarity

[clee]

I'm rewiring the Adapt sensor to go direct to the ecu instead of joining into the std loom wiring .
Reading through searches for TDC the std Ren sensor polarity effects the advance by 4 degrees .Would this also be true in this case ? Same sensor type as far as I know .
I don't know which pole is which on the tdc sensor as there are no markings :scratch:

Clee, my advice would be to bin the renault TDC (same as the 5gt one?) and purchace a nice cosworth jobbie. It will require you to make a bracket for it, but you will save youself a lot of grief. I had nothing but pure problems relating to the TDC and so have a few others that i know of.

Already done that Matt .
Pulley mounted trigger wheel and EFI-Parts style VR sensor .
I've had it up and running for ages but have always had cold start issues .The lump seems to want to run backwards if that makes sense .
Once warm it runs no bother but does occasionally play up after a good thrashing .
I had just spliced the sensor into the old loom and then it connects via the standard Renix big multiplug to the Adapt .
What I want to do is wire the sensor direct to the Adapt avoiding the std loom and plug altogether .
I'm just trying to improve the signal but then remembered seeing something about the polarity altering the advance ?
I can't identify which is which on the sensor ,not sure it matters but ....

Rewired direct and it started a lot better from dead dead cold :)
Only thing is , I then noticed I had no water temp signal as I'd managed pull a bullet off the sensor :rolleyes:
I will have to see how it does it tomorrow from cold to make sure the temp sensor isn't having an effect .It shouldn't but you never know .

fingers crossed :) Im quietely hoping it was just a cruddy cas signal that was not strong enough at cranking speeds to trigger the ECU properly, causing some irratic ignition while cranking.

Hopefully .

I have run it away from any HT ,in fact it now goes in from the other side of the bay away from all other wiring :agree:
