I am also interested in reading a discussion debating the pros/cons of performance chips. I have heard that the EAT CHIP and the DINAN CHIP are two possible performance chip upgrades. I have not heard much about the pros and cons of each or if there are alternative chips to these. I am aware that this forum provides a direct link to purchase the EAT CHIP and that Mark D'Sylva (maker and seller of the EAT CHIP) frequents this forum and sometimes offers discounts for group buys.

I do have some questions about the performance chips before I go ahead and purchase it. If we're lucky Mark or somoene else just as knowledgeable will read this thread and answer our questions.

1. Where is improved performance felt most? (at what RPM, at what speeds, etc.)
2. How does the chip affect torque, if any. Any way to compensate for this?
3. What is the average HP gained?
4. Does this provide better fuel consumption?
5. Do we have to use higher octane?
6. Do we have to reset anything (that is affected/controlled by the DME)?
7. Why EAT over other chips (Dinan, etc.)?
8. Will this chip affect emissions and State inspection tests?
9. How long does someone have to drive with the chip installed before any real difference is felt?
10. What type of driver tends to benefit most?
11. Can the chip improve the performance of a Touring Edition?
12. What price can be offered for group buy?

here's a link to info about the JC (Jim Conforti chip)...most of the info can be extrapolated to the EAT chip as well.

Yes, you will need to use fuel w/91 AKI rating. You can see on the chart where you will "feel" the peak HP & torque. (take into consideration that this web page may have been intiated before the EAT chip was available).

Here's some info I found by going to Google and typing "Mark Dysilva EAT chip"...there were more links to discussions outside of bimmer.info forums that you may find interesting and illuminating:

I just bought one of those "performance" chips off ebay for $25. I thought for that much money why not give it a shot. Got it installed in my spare ECU and put it in the Touring and was pleasantly suprised. Smoother at idle and certainly more power/torque than stock. I run super anyway so that's not an issue. I use a Conforti chip in my 540i and I think the changes were about the same except I don't get a fuel smell on cold startup like with the Conforti chip. The idle is slightly lower at the moment with the new chip but I intend to drive it a few days before final judgement since I think the ECU is adaptive to some degree and the idle level might change. So far it's a good $25 investment.

$25 bucks? What kind of knockoff are we talking about here? Heh.

Doesn't really matter but after purchasing all the brand name chips over the years inluding TMS. Bavauto, Conforti, Dinan, and UUC Motorwerks, the only one I kept because it actually worked too good to pull out was the UUC Motorwerks. This "Panther" chip is really pretty nice and for $25 is hard to beat.

I was in the market for a chip when I came accross this post. I saw the e-bay chips many times but thought what can a 25-40 dollar chip realy do. Well after reading this I bought one on e-bay for about $40 shipped. I got the chp yesterday, and installed it, after having to straighten out the pins because the packaging was almost non existant. Anyway I got it in the car. Reconnected the battery and started the car. At first the idle jumped to 2k and apparently the computer wasn't used to the code but came back down and is actually below what the stock chip was, idles nicely though. Driving the car around town I didn't notice any real difference, not the low end the EAT chip is supposed to provide. I did however notice a higher (4000+) RPM surge, enough to make me think, damn! Anyway, I though these are some interesting alternatives to the $250 chips so I wanted to post some feedback.
Here is the ebayer I got my chip from - x_gen_performance.

could be a copied 'real' chip

Answers:

1) The increase is very noticeable around 3000 rpm. I haven't driven a 535 with one of my chips for over a year, maybe someone who owns the car can explain further.


2) it increases torque at all rpms above 2200. Compensate? Toss a few bricks or sandbags in the trunk

3) At the time I developed that chip, I was not able to create hp/torque curves as the dyno software was not calibrated. I just used the dyno as a rolling road, and monitored a/f ratio when tuning. The dyno is now calibrated, but I have not had a chance to dyno a 535 yet. Bruno (of www.bmwe34.net) compared my chip chip to both the latest Dinan and JC chips and liked mine best.

4) YES

5) 91 AKI (95 RON) or higher

6) NO

7) Whay not an EAT chip? see (3) above. Dinan tunes chips very conservatively, so that they pass emissions in CA.

8) My chips pass in Ontario, and have evan passed in CA on many cars, such as the E34 M5 and 535i. I've heard of one person in the USA whose car did not pass with an EAT chip, in a 540iA. Others have passed.

9) 100 miles or so for the full effect.

10) people who like a better accelleration, and those that appreciate better fuel economy

11) Yes

12) Last Easter, I had a special sale for people here. I didn't remove the sale prices and restore the regular prices as I was busy at first, and then was dealing with diabetes. I was so tired that I didn't change the prices. It's still $188 on the link you will find on this site. During that time, I've had maybe 3 sales. The prices won't get any lower than the $188 and soon I'll be restoring them back to $199, which is a great deal anyway.

When you buy a chip off ebay, you are buying a copy of some other chip that some company has taken the time to develop. You could even be buying a chip with maps that are far from correct as some of those ebay seller are making potentially dangerous changes to the maps. I've analysed a few and seen that for myself. There's no good reason I can see to buy a chip that someone is cloning.

I use an EAT in my 540 and I like it.
