How much driving at IVA?
Hi guys.
Just wondering how much my car will be driven at IVA, as i've never experienced one?
If my megasquirt map is drivable but the acceleration settings etc aren't mapped, will it be ok? As to map it properley it needs to be driven
and the rolling road is fully booked for 6 weeks.
Also, if i set up my tracking roughly myself, will that be ok?
Cheers
Dave.

Dave,
I had my IVA last week and the tester drove it around the yard to test the turning circle, it was only driven for 5 mins max. Bear in mind
you will need to hold the revs steady for the emissions and noise test. I was convinced mine would fail on the self centering but no mention of this
was made (tyres to 40 psi helped).
Cheers,Sean

Ah that's good to know. Thanks for the reply.
Also, what RPM is the emmissions tested?

They drove mine (for SVA) once around the building and a couple of turns on full lock to check the self centering.
The only other driving is through the test lane and back and forth on the brake rollers and then up to speed on the speedo test rollers.
If your engine is pre '95 (and you can prove it) the emmision test is just at idle. For post '95 it's idle and fast idle between
2500 and 3000rpm.

Noise is tested at 3/4 of the revs you have stated for max power - you may need to hold that for a couple of mins. - I did as it was 99.7, then 99.3,
then 99.0 - Pass!
Also during the Speedo check, the car is tied down and driven (rolling road) at 70 mph for ten seconds or so - then a second time if you have to
adjust it - this would probably be the most telling point if it can't be held steady. Mine was adjusted twice (hence 3 'runs' at
70 mph.
I set my tracking very roughly myself - there was no probs on the test but afterwards, it was wearing tyres quick until I adjusted the tracking a bit
nearer what it should be.

Mine got a good thrash round the perimeter of the test centre and we hit 125mph on the speed rollers but it was well mapped. If its not fully mapped
tell him and they will be gentle

At least theyll be understanding then. How long does the full test take on average?

A lot of the 'understanding' is down to the individual tester, some are better than others. Where is your test?
The test will take 4 hours (mine was 08:00 to 12:30) there's a lot to get through.
Good luck!

My test will be at Beverley, as I've heard good words about there. I haven't actually sent my application off yet, as I'm still
waiting for a chassis number off the DVLA.
Sent my letter to them of a week or so ago and haven't recieved anything yet. Might have to give them a ring soon to see what's going on.
