have you had the fc tuned silly question but i thought i should ask anyway, if not that

willbe your problem ,what other probs are you having.

does it idle and does it miss when revving

cheers

it miss's when i rev it struggles to idle and no it hasnt been tuned but it never did it whe i first put it in?

Firstly get the PFC tuned, sounds to me like it's dumping too much fuel in as black smoke is an indication of burning fuel. Even though it "is" a plug and play unit it will always benifit greatly from a good tune. Also put in copper plugs instead of platinum. Coppers make a better spark. Platinums are good for n/a cars not for forced ones, IMO anyway.....

but it still blows smoke with the old ecu in

[race_snooze]

plugs will be fouled to the shit house. They cant burn the fuel properly now.

does any one have the part number for the copper plugs and the gaps please?

[mad082]

either bcpr6es or bkr6es (not 100% sure about the s on the last one, but i have a set sitting on the back seat of the car)

they are the copper plugs, should be gapped standard at 0.8mm, heat range of 6. the bkr ones are the V groove version of the bcpr's.

fixed original problem the got in the car and drov it 15kms it stalled and wouldnt start just cranked no fire so i put the stock ecu in and it does the same thing any ideas?
