Geoff Jeal,Calibration Questions.
Discussion
Hi Geoff how are you, due to the demise of my engine at elvington in 2003 and the Head gasket failures at elvington in 2004 ive been looking into calibration(asking questions ,reading up and looking to a 3rd party tuner for information).
I would be most appreciative if you could "throw some light" on a few questions.
1/ What Base chips do you use on 350,368 and 415 engines?
2/ Under what methods/conditions do you calibrate engines that are modified at your workshop.
3/ What equipement do you use?
4/ For what reason did you put an airflow/fuel flow meter on my car at Elvington under RACE conditions and knowing the car could hit Wide Open Throttle in 2004?
5/ Why did the engine melt 4 spark plugs and damage valves resulting in the complete failure of my engine at Elvington in 2003?
6/when the head gasket went at Elvington in 2004 why did you look into the plenum for oil?
7/Why have you let my car leave your workshop with a base 350 chip knowing the engine is still running lean?
These are just some of the questions i would like you to answer,i have used the forum so it can be debated amongst us and other members and feel this is the best chance for me and others to understand calibration.
Thanks

The Viper guys would be interested in that also.
When supercharging or Turbo we ahve a product called a VETEC 2 that allows us to adjust some parameters.
Major changes are done to a memory stick or downloaded to a box between the ecu and the sensors.
Viper will light the check engine light if suspicious and over fuel the engine, ruins the cats but saves the car.
Come on someone tell us.........

Good questions that man. Reply awaited ..........
Richard ,i asked the same questions on the phone the other day and the reply was "stick to taxi driving and let the clalibration engineer do his job".
There is £24,200 reasons why i would like an answer to these questions.
Aswell as when you have a oil or coolant leak why not address the problem properly instead of smearing the area with silicone,where's my dyno read out 4 years and 1 month on,where are my old parts taken from the car,etc etc.....

Hmmm....... The way things are going, you will probably be more knowledgeable in both these disciplines (and you can lay bricks too).

With an attitude like that towards their customers, how are they still in business ????
The customer is where their livelyhood comes from. If they ask for a description of what they are buying, they should be given it, whether they understand it or not.
Some people are natural at bending the truth and blaming others,they might be cr*p at there jobs but if they make you feel like something is being done no matter how long it takes you tend to believe them.... until you run out of patience.
I think it is high time that common courtesy and decency is shown by the questions raised being answered on this forum.
There is an interesting thread on CCCUK at the moment about naming and shaming poor service.

There are so many so called tuning experts around. And so many fail to perform.
The car above sounds ridiculous that the customer should have recieved it in such a way.
While this type of work does carry risks, these should be minimised by professional service. That is blatant incompetence. Unless the car was returned under strict instruction that there was still problems to be rectified, then wouldnt there be a legal standpoint for such things ?
Is it any wonder I do all my own work. I dont trust most of these so called experts, and my cars run faster and longer than most ( budget permitting )

Shouldnt they have some sort of qualifications to title themselves or is it like some of these other profesions where they title themselves with with the minimum of experience then when things go wrong they dont have the experience to over come problems.
Are we entitled to ask for there qualifications?
Its a shame cos there are specialists in their field that dont have qualifications but have years of experience like some Bricklayers i know that can be just as good as apprentice served brickies.
And where would such qualifications come from ??
Where would such teachings come from in order to gain the qualifications.
The knowledge gained to tune and modify cars and engines are generally acquired though years of experience, working with such things. Certainly lots can be learned from books also, from other peoples work.
It also requires some things that can't be taught I guess. Some have it, some dont. It is a talent, a skill.
Trying to put some sort of exam, that these people need to pass wouldnt really prove anything, but it could well leave some of the most skilled engine builders out of the picture!!

You pick the tuner based on reputation and have to listen to people you trust. It's important to establish 'the contract' at the outset and most people don't do that mainly because they don't know about this sort of stuff. You need it in writing!
This is how I'd choose a builder, recommendation.
If your engine goes tits up you have no real redress unless it's written in the contract, especially with a racing engine. Most people don't expect the worst to happen so don't allow for it. When it goes wrong it's a very bitter experience.

Especially when your tuner has tuned your engine to self destruct at WOT.

Then its down to Track record/Reputation and also if beyond that the person doing the work has the slightest decency about them to be honest enough to hold their hands up and except responsibility without fudging the issue when things go wrong.
Unfortunately for me "Sods Law" intervened and i only learnt that my tuner was subject to legal action on another motor after i had laid 13K on him.
