My Experience - 9XX KH Racing Chip

So what was the outcome of a tale of two chips? Oli only ever received one and there is the mystery surrouding 3 x KH 9xx racing chips (for 944S2 and 944 8v) - including the one that started off this thread.
If anybody understands the concept of a checksum, you will know that this is a way for checking that electronically transmitted or written data is the same at target as at source. It is also an excellent way of comparing large amounts of binary data to determine if they are the same on another media.

OK, I've been keeping a little bit of a low profile on this one. Although, in fairness to Andrew, I should have chirped up a bit more.
As stated a few pages back, I saw this thread at a weak moment - just when I was thinking about getting a chip for my S2. I had been planning on buying a Promax one from Andrew, but was keen to see what else was on the marketplace and thought it would be good to try a Promax one back-to-back with a 9XX KH one. I approached both companies and explained my plans as openly as I could. I stated clearly that I wanted to buy a chip from both of them, test them back-to-back, and return the one I preferred least for a refund.
Andrew (Promax) put one of his chips in the post to me immediately without any payment - a measure of trust for which I am grateful. Jon (9XX) was initially reluctant to take part, saying (quite reasonably) that he was worried I may damage his chip through careless handling (any static discharge would ruin the chip), but said he would think about it and let me know. I can only assume that he was still concerned about the possibility of chip damage and didn't get back to me.
I have now paid Andrew for his chip, and fitted it. However I don't think I have done as many as 50 miles with it fitted, and hence can't offer any decent feedback on the improvement (or otherwise!) it offers. I was hoping to do a long run in the car last weekend, but for family reasons this was cancelled at the last minute. I will however be going to the Essex PCGB meet this coming Tuesday and am looking forward to giving both the car and the chip a good run then. Once I have done this then I'll post some feedback and comments on here.

Ha ha having bought a 9xx chip for my last car you've got to see the funny side of this[
], history repeats itself! I remember when the £100 ebay chip (I forget the name but it'll come to me) turned out to be an exact copy of the Guru racing chip which Promax use.Is there in fact just one original map out there that everyone copied?! Promax/Guru in that case may well be the original as I seem to remember from discussions on the rennlist the original guy was as talented with cars as he was useless in business. It would explain why all the modified turbos have the same fault (that little cough as they come on boost).
I'm extremely tempted with my car to pay Motorsports developments (who are the UK's best and have developed most of the big name chips used by main dealers like the 'Revo' brand for Audi) and get them to write all new software from scratch for my car, maybe even to suit a maf sensor to see if we can improve and add some fresh genes into the 944 gene pool.

in 2004 ProMAX Motorsport purchased the sole distribution & future development rights from a previous developer (who we still work with) for all models (at the time, only the 944 and 968 were being marketed). The ProMAX branded versions were further developed to provide solutions for additional models (928, 964, 911 3.2 and 968 USA for example) and I personally have worked very closely over the years with our developer to ehance our product (based on feed back from customers and our own experience of using/fitting the product). As a result, the range was extended and the product enhanced culminating in the range we have today (924S, 944, 944 28pin, 944S, 944S2, 968 ROW, 968 USA, 911 3.2, 964 and 944 Turbo).
What is clear is that the 9XX is an exact copy of the ProMAX product. My concern for customers is that they are being over charged £50 (£150 is what customers have paid) by JMG (ProMAX charge £99.95 and offer a money back guarantee regardless of who fits it); JMG also market it as their own specially 'Klaus Hoffmann' developed product (which clearly it is not). We have done 3 separate comparisons on 9XX product and each time, it was indentical to the ProMAX equivalent - not only the checksum but also right down to the copyright notice and actual reference data; in fact, any area of the data map we chose to compare was identical.
If anybody else has purchased a 9XX chip we will be happy to read the data from your chip and show you irrefutably what is actually written to your EPROM - no charge. Just phone the workshop to make an appointment (details on website - in my profile).

Maybe it's an organic variety of chip sold at a farmer's market. That should add about £50 to a chip. [&:]

Lol! Hand reared free range I hope. Perhaps there's a market for a 'finest' brand of chips, maybe diamond encrusted and with a gold plated backing plate attached (I'm sure the current buzz words nano and quantum can be added for a bit of high tech to justify the increased cost [
]).

I would add that any chip is a development of the manufactuers original operational code, in this case Bosch.
It is disappointing that some Porsche owners have been mislead and a vendor is misrepresenting and making false claims about a product they are selling. Had I purchased a product under the same circumstances as barks944, I would be aggrieved about having spent £150 on a product that was claimed to be something it clearly is not.
What is also interesting to read are the claims made by that same vendor earlier in this thread.

From jmg's posting on here he seems to be quite open and honest, so he should be given the benefit of th doubt. Referring to him as "the accused" is a little unnecessary IMO. He may too be victim of Klaus McCain Hoffman's dubious products and bought them in and distributed them in good faith. The opposite may also be true of course, but It needn't be discussed on here.
On the bright side, when it comes to chip time for me, my options are a bit easier now! Although how different can an eBay special be . . . . Haha

The thing with an e-bay chip, IMO, is that you can't be sure what you will get. It could be a genuine chip, or a proper fake (dubious as that would be anyway). It could, however, be anything at all with a copied label on it. I wouldn't trust something so potentially damaging from an unknown source, when the saving is so relatively small.
Regarding this thread, the other party is a forum member and very welcome to post. Until then I think it's probably reached a natural conclusion? [8|]
