In the interests of getting some reliable information to resolve the competing and sometimes pretty suspect claims by various performance suppliers, especially chips, I'd appreciate your opinion as experts who've improved and dynoed plenty of cars.

What is the likely realistic (not just claimed) improvement in rear wheel kw in a stock 3.9mpi (a) auto and (b) manual in good condition by adding

1. a mild cam like Crow's one for 3.9/4.0
2. a mild cam plus headers, 2 1/2 exhaust, and free flow cat
3. a mild cam plus headers, 2 1/2 exhaust, and free flow cat plus a programmable chip
4. a programmable chip on its own.


Am I right in thinking anything but programmable chip is a waste of money, and that the benefits of a programmable chip will be a lot greater if basic mods like cam and headers are done first?

HI to all you Blue bloods.
As far as the camshaft department goes we have tested plenty of camshafts and found that only a few grinds realy make the type of power that is overall worthwile using on ea onwards .My experiance is that a gain of approx 10 to 12 kw at the rear wheels is to be expected.With exhausts i have found up to 8 kw at wheels with a cat back system.With our header @cat we gain anywhere up to 18 kw.As far as chipping goes i believe that the only way is to tune the car in real time.Hence tuning the car on the dyno.It is very hard to tune a engine from the keyboard in my office.We are always helping people with the so called plug in chip that will make some stupid result by just plugging in the chip to the test port of the computer.We do not claim any big results from our mapping of the computer ,but usually a gain of about 5-10 kw at the wheels is the average result.What I do say is that throttle response @acceleration will improve .we must always remember that by chipping the engine we are trying to tune the engine to its best potential.Some cars respond better than others.Due to engine condition/engine specs.I t is my beleife that only a programable computer is the only way to go.DO NOT WASTE YOUR MONEY ON A PLUG IN CHIP UNLESS IT IS SET UP ON A DYNO or from a tuner that has a dyno and can prove the results when it is fitted.I have done power runs on cars with chips fitted/then removed them @ the car has made more power.
Regards to you all Rob herrod

Rob Herrod, when you do 'chip' modifications/enhancements on Fords do you keep the standard Computer and use an EEC Tuner?

Or do you go an aftermarket computer like Motec or something?

tuning

we use on road cars uni-chip.we also ran the unichip on the ford factory entered xr6 targa tasmania car.very good value for money/good reliability.we also use on the upper scale motec.

Just another quick question - is the Unichip tuned for a specific type of fuel, or just a grade?

eg. if mine was Unichip'd and tuned for Optimax, would that mean that any other fuel with the same RON would still work the same, or would it behave slightly differently? Would it ping it's tits off on something like Vortex in this case??

I would also like to add that if you are going to go the chip route you must get the work done buy someone who knows what they are doing. A programable chip is only as good as the person on the dyno.
Getting this mod done on the cheep won't give you the best reasult.

I agree it is up to the person tuning the car/as far as fuel goes ,have the fuel you are going to run in the car ie optimax or vortex,shouldent worry if you change fuels.we always tune with this in mind when i set up my maps so as no pinging will happen.if fuel levels are lower,again pick a good well known tuner

Hi,

I think the fuel used does make a difference when getting a chip tuned.

I got my Unichip tuned when I had a tank of Synergy 8000. At the NSW Tickford club dyno day I got 130kw with synergy (almost emplty tank).. I then changed fuel to optimax , and on the same dyno, same day - I got 124kw.

My car will run fine on Synergy, and BP Ultimate, but if I put optimax in - the car pings its nuts off.

I dont know - maybe all the Shell's in my area sell dodgy optimax.. thats just my experience...

Guys

Guarantee I thing, the 2 cars i have run EB and XR both had Unichips in em!.

Rob is 100% right when he says they are tuned on the Dyno you get a better feel.

I made the mistake of some shonky tuner on the EB initially, Sorry Rob this is well before I met you, and to compare it to Robs work its just like chalk and cheese!

I will never run a car with a uni chip or a FREE MOTEC SUPPLIED BY ROB HERROD (hint Hint) in any of my cars in future!

Doesn't Ultimate and Optimax come from the same refinery????
I thought under the oil companies' sharing arrangements this was the case, thus your dodgy Optimax would be the problem of your servo, not Shell. (Synergy I understand is different though).

This is addressed to Rob Herrod:
Have you investigated the Autologic / C&M Motorsports Ford EEC programs? From what I've read this is the best reprogramming system for the Ford EEC. The guy behind C&M Motorsports, Mike Wesley, has been working on the Calibrator which can manage EEC changes on the move. Once it is released onto the market it will be the most powerfulest programming tool available.
My two cents worth!!
