Terrano 'Speedbox' for sale

[Kishada]

I've gone for a more complex system so this is up for grabs.

Suitable for both Zexel and Bosch pumps, the instructions cover both.
I've been running it with a Bosch pump, details in signature.

In theory this simply increases the fuelling by the same percentage irrespective of rpm and while it will go from idle up through the revs without an issue, the thing I cannot live with is the engine shudder as it drops back down from 1250 to 750rpm (ie idle) when coming to a stop. My head has been double skimmed as outlined in previous posts and as it transpires my thermostat is stuck open! possibly leading to it running rich at idle to start with.
All i can say is please don't hold me reponsible if decide to take it and suffer the same problem!
It is adjustable and i've currrently got it set at -1.75 turns from how it was sent.
It causes just a minor shudder when returning to idle but gives some boost.

If no one wants it we'll see how it runs on a Zexel pump on veg courtesy of arcascomp as he'll become a test pilot if he wishes
