What tuning chips are available out there?
What would YOU reccomend?

Again,
Like induction kits, they only really work in cars that have lots of built in trickery such as Turbos etc. Various claims abound, but unless you are looking at throttle bodies, new cams, new exhaust system, then I wouldnt really bother.
Sorry, not quite the answer you were after.

No , that is exactly what I want to hear!
Anything that stops me wasting money is good!
I don't mind spending, just like to kmow that i will get what I wanted!

Last I was looking at this I came to the conclusion that I'd need;
New cams
New exhaust (possibly with race-cat)
New injectors (?)
Remapped ecu (probably done on rolling road)
Induction kit.
Ended up looking very expensive, and as you are lucky enough to be able to get FRP's overthere, go for that instead ;-)

To increase power you need to feed more air and fuel into the engine (in the right ratio!). The ECU basically handles the fuel based on a map which simply put gievs the ratio based on what the load is.
Teh air ratio can be slightly altered by changing the timing. BUt you will need to get much more air in to make a noticeable difference - i.e. chnage cams / entire exhaust system (manifold / system), gas flowed head, etc.

Finally it looks like my Throttle body conversion will be finished. I should have some pics this weekend. Unfortunately though I'm currently in the Gulf and won't see the finished result for a couple of months :-(
I've got an OMEX ECU, which after much mopps around is piggy backing the Ford ECU and using a spare trigger wire to run the VCT. At least I think what the mechanic said!
I'll keep you posted....

You can't improve on perfection (and millions spent on R&D) - Puma's are already 'tuned' by Yamaha (ie professional job) - buy an FRP...

Erm you can, hence why so many good tuning houses exist.
Most performance cars are not tuned to their highest ability to provide reliable power, that can be replicated across the entire fleet.
Point comes that to squeese the extra BHP out costs money.
If this wasnt the case, why is it so easy to get an extra 200BHP from an escort cossie over its original Ford power???

getting the extra power is the easy thing... getting reliability is somehwat more difficult and something tuning houses don't do to anywhere near the same level as the manufacturers - hence the reason why they have to play safe... the car has to work across a large range of: weather conditions, fuel qualities, service intervals, mechanical (eg sensor) breakdowns etc.

As I said, unless you pay above 40K, the car you buy is a compromise between power, and cost.

Like I said - buy an FRP - LOL
But you dont buy an FRP for the power.
The FRPs biggest selling point is is glue-like ability to stick to tarmac.
That said, there does seem to be a few list members who have found out the hard way that when the glue comes unstuck, it does it with very little warning, and that the consequencies of finding the edge of the handling envelope can give you a very nasty paper cut....
:shock:

I have a Unichip on my FRP and it proves that 'perfection' can be improved on by someone who knows how to tune these chips properly. The car drives noticably smoother and pulls more readily.
Like anything it ain't what you do it's the way that you do it...

Question though. Did it improve "power" or driveability?
To improve power it must have adjusted the airflow, and on an NA car, then max airflow if finite, and dependent on the size of your inlet system. That said, Unichip do have a reputation for being very very good, and as you say, if played with by someone who knows how to get the most out of it, then things can be improved.

Power increased by 4bhp.
Definite improvement in drivability!

So you got a 2.5% power increase for loads of dosh.
That said, the driveability would be dramatically improved.
Colins car could be classed as the definitive answer to chipping.
You do not gain much of a peak output increase (as this is limited by the physical constraints of NA engines), but you can (subject to correct chips) gain a real improvement in the way the power is made available.
Cheers

For day to drive driving the increasin BHP is no where near as important as the way it is delivered i.e. the torque... from memory Colins car had approx 10 ft.lbs torque more than standard - hence its drivability was greatly increased

The best tuning chip? That made for your car, on your car, in realtime. Commercial chips have standard maps to fit on standard cars but you know that every engine is unique. A realtime map modification is the only way to obtain the maximum from a car.
The original ecu is far from perfect, i've seen the original and my modified maps (1.7), the difference of ignition over 5000rpm now is around 30 points less and to be perfect should be at least 40 points less, so the original carburation is very rich.

You will also find that the sensors used by the ECU are also a limitation... a slow reaction time wont help matters, also the ECU isn't good in overall performance - so many compromises have been amde due to emmision considerations - hence the reason why superchips et al can increase performance a small amount.

re: the unichip for the FRP, how much does it cost? also I`ve read (don`t know how reliable info is) in ford mag that u can do a port smoothing jobbie on the FRP for £600 fast road, or £900 like racing sort of spec(I think ages since I read it) dependant on spec and get another 30-35 bhp max whats your views on this? :?:
port sommothing jobbie... waste of space... as long as the basic air flow is reasonably smooth (no jaggies / casting marks) then thats as good as you need... I also suspect you would be a guinea pig as well... all that you read on head polishing is massively overated - what you are doing is simply working you induction / combustion process harder - as you have removed all the turbulence effects which help mix air and fuel together... also consider the loss of the boundary layer effect which effectively slows the air down as the port diameter has increased slightly for the same volume of air.
Matching inlet manifold port to head port is a good thing, well it was about 20 years ago when menufacturing tolerances were not so good... these days I doubt you will find much work to do.
30-35 BHP ? total and utter nonsense... you can only make power by getting greater MATCHED volumes of air and fuel to burn at the right time... by porting you have only achieved part of this (and even then to a minimal degree...)
