Carrera 3.2 Performance mystery and Chips (long)

PS, its a little after 10 here in Cali. My rule is to not drink before 11, but as Steve said it, cheers!

BigD, MAF needs different software from a typical AFM chip. There is a new MAF unit that we have under production now, with the first unit expected at the earliest by around March. It uses the Bosch HFM5 from the current BMW E46 M3 specification and is encased in a computer optimized carbon fiber measuring tube. There is a digital signal converter with an integrated atmospheric pressure correction sensor. It is designed to be plug and play in 20 minutes without destruction to the original airbox or wiring harness. Everything is being produced in Germany right now. But with Bernd being extremely busy at BMW M and myself outstretched in many projects, it is not of the highest priority right now. It should work with both the 3.2s and 3.6s. More later when it arrives. Here's a couple of pics of the prototype:

That's a grand idea Steve, and although I will not have dyno runs to prove it, I'm sure a few beers will make me 'feel' better !
Have a great weekend everyone!

ps: GO PANTHERS!

how about a loren and steve w cage match, winner take all?

loren is an one of those engineers that has spent too much time in books and does not have the ability to deal with other humans. i work with civil engineers, the really good one have the personality of a rock, the ones that are so-so you can talk too. ultimately i like dealing with the ones that can carry on a conversation. anybody ever met loren? i imagine he's like the professor on the simpsons but very angry.

It's past 11 somewhere so drink up.

Maybe you should just 'change your rule' ...it's now officially 'Miller Time'...although I wouldn't actually drink that stuff!

[BigD9146gt]

OH BABY!!!!!!!!! Sign me up! Not to be a snob or anything, but the Autothority MAF which was modified from the ford mustang cobra doesn't look nearly as nice as that beauty from one of my favorite Munich companys. Thats quite a project... any ball park figures? Thanks, Don.

Oh and Keith, come on now son, its only Spaten on tap here!

Someone ID this chip:

It is from a casing that is marked 911.618.11.20 (Bosch # 0 261 200 082).

This is all the markings on the chip inside the casing:

Malaysia
AM27C64
-150DC
9517BPA
12.75V PGM

I believe I have the 358 chip (if you don't know what these numbers mean, go back to Steve's first post), and the only validation I can find is on this list that I saved from sometime ago. (see the last row)



So is it a 358 chip? Where are you guys seeing the series of numbers that Steve listed, e.g. 1237355358? There is no sticker or anything on the back of the chip I have, just etched markings listed above.

Off the top of my head

AM27C64 -150DC Part # 150 nSec access commercial temp DIP
9517BPA made the 17th week of 1995 (lot BPA?)
12.75V PGM it needs 12.75 volts to program


No info on what it is programmed with.

[MotoSook]

Dangit! It must be an aftermarket chip (if the date is any indication) I was hoping it was stock. Thanks Rick.

[kepperly]

Steve,It finally happened, no more 93 octane available in my
area. What is the procedure to have my SW chip reset to the lower octane fuel available. Is this more important in warm or cooler weather?

Souk, your chip could contain anything, from a copy of a stock 358 program to an aftermarket chip. It's obviously a copy of something and all depends on what was put on there. You are welcome to send it to me to find out. Reading it is the only way to know.

Keith, you can send the chip to me for reprogramming. Contact me at steve@911chips.com for details. It's more important in hot weather, however it's still important minimize high rpm full throttle operation using 91 octane with a 93 octane program, no matter what the weather conditions. Low and mid rpm and part throttle, you should be fine.

[KCinBR]

Steve, I also have one of your 93 octane chips. At this time 93 octane fuel is available but I"m sure in time it will dry up. My question is........can the fuel quality switch on the DME be used to compensate for having to use 91 octane or lower?

[RSupdate]

A little late here, but Thanks Steve for all your hard work on making undoubtably the finest 3.2L chips ....ever.

2006 was a very good year for me at the track......

Let me ask an ignorant question:

Isn´t the software / programming gear for mapping an ECU chip much more sophisticated and accurate nowadays compared to what PAG used 20+ years ago ?

Should it, hence, not be easier today to map a chip optimally ?

Just eager to understand.

It was because of his *combined* knowledge of how an internal combustion engine works...and for his chip programming savvy. Can't just be good in one area.

"Conservative aggressiveness"....good label for his chips....

Thanks everyone for the kind words. Souk thank for digging this thread out of the basement!

You probably should be able to use the FQS to detune for lower octane fuel. Porsche did this a lot with some of the Euro cars in Europe - many UK cars from what I have seen. But it may unnecessary detune in some areas more than necessary, and possibly not enough in others, so try it, or best is to have the chip reprogrammed for the appropriate octane.

The knowledge and the programming software 20 years ago was certainly much more proprietary and secretly contained within Porsche and Bosch - and it still is unless you work as an programming engineer at Bosch, Porsche, or BMW and had access to the archives ( ... ) The equipment and programming gear is certainly much more compact, quicker, and less cumbersome than what the automakers used 20 years ago and makes it much easier to set up and make changes. What would have previously required at least a few hundred pounds in test equipment and the entire passenger cabin, can now be contained in under 10.

Hey wait, I thought this was all BS back in '04......?

It's kind of entertaining to read Loren's posts again. Note, I said "kind of".

BTW, I was out running electrons thru my Steve W chip this morning. It still feels great-especially as I was rplaying with a 928S4, and surprized him as to what a little ol' 6 banger can do.

Without casting aspersions at any one or in any one direction the fact remains that if you benefit from the product you are promoting a ‘conflict of interest’ is always lurking.

The chip treatise (good as it might be) is an Advertorial.
