Hi AGAIN Guys,
Yet more questions Sorry....
Whilst setting the valve clearances on the AJPV8 4.2,How long a job is this please....????

Also....As i understand, The throttle pots require a laptop with the correct softwear to do this right....
How much is the softwear to do this job please...

I`m very,very interested in getting a cerbie but would like to know exactlly what to expect first....I would be only doing around 2k miles per annum and was wondering just how frequent the tappets and throttle pots would require checking with the milage in question please....
Thanks in advance guys....Kev.

Valve clearances can take between an 1.5 to 3 hours depending how many require adjustment. These are checked at 12000 miles and adjusted as nec (normally at extra cost).

Throttle pots are checked at 6000 mile sevice, but I recommend tuning is done more frequently coupled with a once over at 3000m/6 mths(spanner all bolts, check for chaffing pipes)...doing this will reduce common failures such as ht leads,pipes etc and reduce service costs in the long run.

If you only do 2k a year then invest in a good battery conditioner, Tvr's eat batteries....also dry store and a wax oil of the chassis is a god idea.

software etc is available here http://homepage.ntlworld.com/dave.hinns/software.h...

the cerbie is an awesome raw power full on monster, everytime i work on one I still get that same cheesy grin when it comes to road test....I personally will be getting one next year and starting an interesting project which involves a major refit,carbon bits, rear wing and a new heart (this is a secret at the mo)...but it will have a 7 speed sequential box!!!

There are endless mods that can be carried out from sports exhausts, suspension even NOS!!!

You need to get in one and test drive.....now!!

If i purchased a Cerbera.....(I`m very,very interested in a 4.2)...Is it possable the throttle bodies can be adjusted by another non laptop way..Or...Is the laptop way the only option....???,As,I have a laptop but are only a novice with the old computers and that brilliant piece of info above i felt is a little out of my league just yet...(Just could`nt understand it sorry)...
I have and still do tune multiple carb set ups...But,Suppose this would be more Ohms related adjustment.....???.
And,There is no one close to where i live who could undertake this operation for me every 6k miles which is rather a concern to my purchase/Interest......

Thanks....Kev.

Unfortunatelly the laptop, or any old computer with a serial plug, is a must, as the pots are set by percentage, although this will be by resistance but not shown in it. Also the software can reset the adaptive maps, clear logged faults and you can see much more information.
I did my own tappets and other than plucking up the courage to do them (gulp) it wasn't too bad of a job. I took a morning setting it up and taking it apart, ordered the shims, then when they came another morning putting it back together and tidying everything up.

I can't figure out why your so concerned about this. If your buying a Cerbera, then adjusting the throttle pots really is the least of your problems.

If you're capable of balancing a set of carbs then using a laptop and the cerb software won't give you any issues its very straightforward

Mechanical and software balancing are not mutually exclusive, and valve clearances need to be correct. Attempting anyone without the other will be a stop gap measure.

I know search was offline yesterday, but there is plenty of info if you are interested.

If you are looking to buy, a professional check and set-up would be the way to go until you have had a chance to familiarise yourself, and should therefore not be a consideration for which car to purchase.

Thank you very much guys for your comments/Help,I do appreciate each and every one...

The reason Adjusting the throttle pots are so important to me is becouse..:-
1,The nearest TVR / Indipendant to me is around 100-130 miles from me...And,With this being part of the service..This should be taken into consideration..Whats the use of having any car and not be able to keep the thing on top form...Eventually,Everything grinds to a halt,Becouse its time for a 6,000 mile service and no one local has the equipment to carry out the job....I feel this very important indeed..Doing the valve clearances dose`nt represent a problem...

I like to look after every car i get myself....The only time thay go into the garage is for the annual mot test....Basically,The garages up here ar`nt worth a S**T...Doing most jobs myself guarentee`s me that the jobs done as it should be done....Time is`nt an issue then.......

I have helped so called specialist`s and on several occassions have shook my head in disgust with some of the workmanship being honest...

I know you guys would help out with any info i may require..To which i thank you again....But,I also hope you can see where i`m coming from....I would hate making the car have more problems than the norm becouse of neglect ...
Thanks guys....Kev.

You could set them via a multimeter if you know the start resistance,but the problem you would have is syncronizing them when adjusting the throttle bar...unless you have 2 multimeters.

The laptop way is alot easier and when you have used it once you'll find its not to bad to use at all...
the benefits are you get to see all the live engine data, lambda probes and things like the thottle pots of both banks on the same page...it makes it easier to adjust whilst looking at a screen rather than fumble around with multimeters.
If you go to one of the tuscan races or club meets someone is bound to help and show you...I know I would.

As was said above, if you can set up multiple carbs etc, then using live data is a walk in the park.

If the most important thing to you is keeping the throtles in balance / reducing throttle pot problems just factor a change of throttle pots into your service schedule. they're 30 pounds each, so for 60 pounds you have a pair of new pots every service and peace of mind. In the time of your ownership this isn't a biggie. Wait till you have to have the chassis top tubes under the manifolds replaced, that's the time to get agitated wink

Thats right,if you use a standard serial lead you run the risk of damaging the MBE (although pretty unusual as in the 90's when at the dealer we only had standard cables). As they are cheap to make just get your local comp shop to make it up. Its best to get have the lead quite long, this will allow you to have the laptop close to you. The connection is simple..just remove the lid of the MBE and the serial port is waiting for you....On later cerbs a fly lead was fitted, there is a cable for this version which can be made up or bought from somewhere like Clever trevor.

On that link you have both early and late versions of the software...You may find when you go to download the software from the site it comes up internet not found..In this case you may need to just wait a few days and keep trying as there is a monthly download limit on the site. You also have service manuals and so on.

Cheers,Stu

Hi Kev,

This may seem a little harsh but I only say it to save you from a lifetime of pain and misery with this car......
If you're planning on doing 2000 miles a year then get something else. Cerbs require reqular running to keep them in good nick.
If you're so worried about running costs then get something else. Cerbs are NOT cheap cars to run
If you're worried about driving 130 miles to have a service done then get something else. My 1000 mile round trip is a pure joy (apart from the speeding fines).

....and finally....
If you think "The garages up here ar`nt worth a S**T..." then you should look at your spelling prowess.....

Sorry, but it's for your own good (and the good of any Cerb you might actually buy)

Good luck,

Paul

Well thats told me.....Ha,Ha....
No on a serious note...Thank you for being honest Paul, I would only be using the car for the 2000 miles..I`m a stickler for clean oils and Good quality oils at that..But,It would appear the Cerbie needs quite a lot more than general mentainance.....Which is a shame really,As i had my heart set on one....Oh well...Where is the Totally reliable Japanese cars then....?????

Bloody hell Paul - "A bit Harsh"!!!!??????
I should say so.
Since when does a body need to have a degree in English lit to own one??
I agree with your comment about running them regularly but for christs sake making personal comments about a persons "Spelling Prowess" doesnt help anybody!!

Ok Steve - and breathe !!!!

I live in the South East where there are numerous possibilities for servicing. I still choose to travel 140 miles to have mine done though. Just another good excuse to go out for a spin. Don't let the doom-mongers put you off. Provided you have a bit of mechanical experience, and contingency for when it all goes wrong, it is worth every penny.
