What sort of things do they change if you have an injection mini set up on a rolling road?

You asked this before?, no? why do you ask? is it not running right?

Nothing I dont think other than finding faults with the system, the ECU is adaptable and tunes itself, if its working correctly that is.

I may be wrong but no one knows. I'm just waiting to get mine on the rollers.

yeh i might have asked before. Im not really happy with it at the moment, it isnt particuarly smooth, and i occassionally get flat spots, i adjusted the valve clearances and it went from a loud tapping to a quiet tapping.
My fuel economy doesnt seem too great either there might be a vacuum leak or something similar, ill have to have a look

I was simply wondering if there was anything else i could check that would improve the driveablity of the engine.

It still feels great at higher revs its just at slow speeds its a little twitchy

sorry if i am repeating myself from another post i may have made.

Have you replaced the oxygen sensor? Do fit the genuine Bosch item

When do you get flat spots?

Have you adjusted and indexed the throttle?

Do check the thin vacuum capilaries, replace the ends with the new rubber ones

Do replace the fuel filter

Do fit the right spark plugs

I have replaced the oxygen sensor although at the time i was unable to obtain the bosche item.

flat spots in second gear between 2000-3000rpm medium throttle

i have indexed the throttle and will shorlt be greasing the throttle cable.

will check the vacuum lines.

i havent replaced the fuel filter i dont know where this is, will be shortly getting a new air filter elelment.

Shorty changing spark plugs, which are the right ones to get for a spi mini? I have seen copper core and v-grooved advertised. Whats the difference? Which is the better one?
