Nosram ISTC v2 cogging ?

[tc3nitro]

I have a Nosram Pearl ISTC v2 that I've just fitted to my 4wd and I am having issues with it cogging at low speeds.

When you go for the gas it seems to cog a little then boom it off !

I have changed the sensor lead and checked everything and I can't find anything obvious.

Has anyone else had this problem or can anyone point me in the right direction ?

I have spent a few hours trying to sort this now !

I have tried cleaning the motor (even though it's only about 5 mins old)
Changing the sensor lead to 3 different ones
Changed the cap and associated wiring.
I have unplugged everything else from the receiver
Battery's are fully charged

Now it only does it under load. If I pick the car up it runs perfect !
Once I put the car on the floor or provide a little resistance then it just stutters/cogs.


Anyone any ideas as I'd like to run this tomorrow ?

I've tried that !
In fact I've tried changing all the settings on the speedo and no luck... :-(

I can't understand it as it was fine in my 2wd last weekend.

retune esc to tranny for new channel and see if that helps, unless your on the same channel for both

Thanks for the reply but I have already rebound the receiver.

I'm fairly certain this is a speedo fault, think ill have to return it to Schumacher and see if they can find a fault.
