Chips Again

[Andy Tims]

What's the consensus on aftermarket chips?

Superchips are quoting + 15BHP for £293.73 fitted + £50 for a rolling road test - They don't have any comparative torque of power graphs.

BBR GTi say Starchips give 10% extra torque & BHP for £235.00 fitted! - No rolling road, or graphs.

Apparently Bob Watson does a chip, but he hasn't yet returned my call of a few days ago.

AMD apparently no longer do their chip for the Carrera 3.2

Can anyone give me a concise report on the Steve Wong chips?

Thanks in advance.

Have you tried AmD in Oxfordshire? Can't remember the number, but they have a very good reputation.

 

[Andy Tims]

Oliver

Yes - they said they no longer sold the Carrera 3.2 chip. Mind you the "lady" I spoke to did sound a bit vague.

Do you know for a fact they still sell their chip?

I think you missed the 5th paragraph in the original.

OK, I'm not being helpful, but then my 3.2 was reprogrammed by AmD when they converted it to run on 95 unleaded (heavily modified car)

Andy,

Cheaper solution,

Stop eating them (chips that is) loose 1-2 stone and be 2 secs a lap quicker.

Regards

One of the reasons for buying a lightweight 911, was so I could keep eating chips (and curry). Anyway at 2 seconds a lap quicker, you'll have to move over.

and now can we get remotely back on topic

 

[Mark_Bennett]

Try Jeff Everett. He used to run AMD, now set up a seperate company.

Suspect you might be interested in the Hotfilm mod as well...

Edit: Thanks to Peter Skelton who filled in the details (Name & phone number) when I could not remember!

You ought to do a search for "performance chips" - or just search on my posts over the last couple of months.

Try here: http://www.porscheclubgbforum.com/tm.asp?m=29300.

Both Jamie and I gave our perspectives on the SW chip. There is also opinion from Wayne Schofield and posts from SW in this thread.

IMHO (and in summary), if you want the best (and are comfortable with the price), get Wayne to look at your car and burn a custom chip based on dyno pulls. If you want "some" benefit at a great price, take a look at the SW website and buy Steve's chip. Bottomline for me, is that I would buy the SW chip even if it gave 0hp gain as it still corrects what I perceive as faults in the original mapping and enhances the driving experience. I personally think that for a standard 3.2 there is not enough left on the table to justify spending a lot of money on chips. The SW chip works on my personal cost benefit analysis. If I had a car with cams, hot film etc or I was racing, my take would be very different. YMMV.

PS I would be highly sceptical of the 10% claim - thats 23hp. I have never seen evidence of that sort of gain from just a chip. Look at the post on the Scottish register where Mike Barnard gives an account of his much (externally) modded 3.2 on the rolling road.

Bruce Anderson checked various chips a few years ago and none got more than about 5hp peak gains IIRC. Most gained 1 or 2hp []

Hi Andy.

If you look at recent PP's you might see that the 911 Club Sport register has been working with a number or other CS drivers (from around the world) to develop a specific Euro chip.

We have been testing and modifying this on cars (mine included) for a few months now, deriving ever higher performance software. Steve's chip's are excellent value.

They have improved the drive of the CS (and other Carrera 3.2's) no end, and road dyno testing proved very very impressive. We have optimised for standard back box, free flow exhausts, special air filters, free flow pre-silencer and so on - all in seperate or combined software.

Tell him what you have, and he has the optimised code.

Importantly, we're optimising AFR for Optimax fuel and the lower ambients we know we get in Europe, together with the slightly higher CR of the Euro engine.

If you contact me or Steve Wong from his web site, you will get excellent service, and he will know exactly what chip to supply you. Of course, a fully detailed rolling road tune might be a few percent better, but it will cost a whole heap more, and if the RR tuner is not experienced enough, they may just optimise your engine for wide open throttle. I have learned that WOT is easy to optimise, but Steve has spent a lot of time optimising part throttle.

Look out for this months PP - it may contain an article to help you.

Also, the CS newsletter (are you on my circulation ?) sent out last month, details the work I'm doing to some extent. Interestingly, we have really worked hard on the part throttle settings, but the engine performance over 4500 is also very impressive now.

One statement to make.

Dont do a thing until you speak to Wayne Schofield.

He is very reasonable and its bespoke!!

Just look at the info from the Scottish guys from a couple of weeks ago.

If you want his contact details, e-mail me on bakermin@hotmail.com

 

[Mike58]

From the Horses mouth
Wayne costs ( currently) £250+vat
YOUR car is optimised.

[911sse]

exactly mike, I am just away to arrange for him to work his voodoo on my car..............

 

[Guest]

Please let us know your first hand impression in as much detail as you can. Any objective facts would be great but subjective feelings will also be welcomed []

 

[Andy Tims]

Cheers for the advice guys.

Have made contact with Wayne today. He is very busy at present, but looking to get him to sort me out next time he's down South.

I have had a SW chip installed for about 6 months.

Steve, as I am sure you are aware has 2 Euro chips - I went for the latter of the 2 that gives a "race car feel" (burns more fuel - but that's got to be worth it!)

I am very impressed with the chip and his service.

The throttle responce and power increase have noticeably improved. Steve estimates that about 1/2 a second could be shaved off the 0-60 run. I think this is about right.
I must point out that I have never timed the 0-60 (I will this summer) and have never put my car on a rolling road (can't be bothered this summer)

IMHO go with SW - look at the exchange rate! my chip cost about £130 and took me 30 minutes to fit it.

The best of luck with your decision.

I have actually gone for the Steve Wong chip after speaking with Steve Darnell. Steve W has developed a couple of specific chips in conjunction with Steve D for the Club Sport & was able to optimise mine for 97 Ron fuel, since Optimax is hard to come by locally to me.
This may not be quite as bespoke as the Wayne Schofield option but:-
1) Wayne is obvously still very busy as he has yet to contact me with a date.
2) Despit the price rise in the last few months, the exchange rate has meant the chip has only cost me £158 incl shipping.

Will fit it at the weekend & advise how I get on.

 

[Jacob]

Andy,

Good choice!

Fitting is very straight forward, you don't have to be technically minded or skilled to do it.

Let me know how you get on in your first blast. One of the first things I noticed other than the pull from lower down, was the fact that the revs kept on going and going. Steve adjusted the limit from 6,250 to 6,750, but if you have the CS that may not be as exhilarating for you!

You won't be disappointed

 

[zwhitea]

Out of interest has anyone gone down the route of having a Uni Chip fitted and mapped by some like;

Velos in Burton on Trent,
Owen Development in Oxford or
Storm Engineering in FIFE..

As I would be interested in any before and after Dyno charts for cars with a SW chip and a car with a Uni Chip.

Because at some point I'm going to start looking at chipping etc... just so I look respectable against friends and collegues many who have monster JAP Imports...

I have no experience if the chip companies you mentioned, but in point of fact, changing the values is not the issue. I'm sure they can all re-program the code as well as the next man.

The advantage of the SW route over someone (like) XXXXchips has to be the hundreds of hours spent understanding the effect of a point or two on timing, when, and how much fuel works best under what throttle loads for our cars - namely a P911.

Steve W (by virtue of his many yrs. of Porsche ownership) has a good balance of cost /performance. Frankly, and as this thread points out, RR tuning may release more hp, and there is the thought that is suits "your car", but it does cost more. You pays your money, and takes your choice.

FYI - We are still working on the final optimisation of the chip to be used with Optimax fuel. A great deal of time has been expended in testing part throttle settings - something very hard / impossible to do on a standard RR tune.
