Have got interference from somewhere, my throttle enrichments ars spiking all the time. Have had a look and found that my power to ecu shares the same circuit as the feed to the coil . Also my loom from the wideband goes under the coil is this ok.

Are you sure its not just the threshold set too low?

You using sheilded cable grounded only at one end?

Cheers

I would not use the feed to the coil for your MS.
A seperate fused feed (ignition switched) wolud be best.

Have good look HERE if you have not allready done so.

set the threshold at 20.00 and it still did the same so i know its not that, have been trying to map car for two years, have got it close but not quite there because on cruise it jumps between 14 and 16 i do believe this is the problem.
