Has anyone every tried (or heard of) Eurobahn ECU mods? Their power and torque claims are way higher than anything else that I have found.

I am bit leery though. They show almost 20HP more gain in power for a "4.2 V8 GT" compared to a "4.2 V8 Coupe" even though the engines are identical (the only diff is the GT is a manual Trans).

If they can indeed add 50HP and 38 FTlbs of torque to the GT that would be pretty amazing but I am skeptical even about the 32HP gain stated for the Coupe.

Their claim is 32 hp for the GT. The 50 hp. number is for a V12.

Otherwise, anyone have any experience with this company?

Every software writer makes ridiculous claims.

The honest ones will tell you that the most noticeable gain is fuel economy because the ECU is optomized the the particular area octane rating. Thus it's not averaging fuel octanes but then buring for a specific value which makes the engine run more efficiently.

Huge HP gains? I don't so.

What are theya sking for the upgrade $4k-$5K?

I would not buy any of these claimed gains w/o hard proof=dyno results!

HP Claim

The claim for 50HP on the V12 would make sense except that's not what their site says. It specifically states:

Maserati Gains Torque
4.2 V8GT 390hp 50hp 38lbs

At best, this is sloppy advertising.

Formula Dynamics seems like a good alternative. They claim about 20HP and have a dyno graph to back it up. Has anyone tried their chip?

Try the "Exotic Tuning" link....

Looks like the 50hp gain is for the 6.0 V12. 31hp for the V8/390 Coupe and 32hp for the V8/400 Gransport according to info on this link.

HP gain

You are right. The other one is evidently an error - they should get it fixed to avoid confusion.

Does anyone know if their mod for the V8 actually adds over 30HP? FD advertses 20 as does EuroTek while LeoNardo quotes 18.

Throttle response is a possible gain. My 997 C4S has a "sport" button (that's not what Porsche calls it) that doesn't give any more power, but the throttle opening is greater in the first part of the pedal movement and the car really does seem quicker (it isn't, but the feeling is a definite plus).

Anyone know if this feature is incorporated in the chips?

Throttle Response

Interesting that you should note throttle response. That is what Formula Dynamics said was the largest improvement that would be noticed with their chip (Jeff at FD told me that the 20 HP upilift by itself is not really that noticeable given the car's high base power).

On a different note, how do you find the 997 in comparison to the Mas? It was a toss up for me but I preferred the style and motor of the Maserati Spyder to the Porsche 4S and I reasoned that I could bring the handling closer to par with aftermarket mods for only a few thousand therefore making the two very cost competetive.

I traded my 997S for my Maserati, and have not looked back since. I was not a fan of the Flat 6 in the Porsche. The sound and the power are far superior in the Maserati.

I don't want to hijack the thread but had you had other Porsche's to which you can compare the 4S? I am interested in the 4S but extra weight concerns me. Thinking a 2S with factory engine power package at 381 HP would add a jolt.

I recently installed the FD piggy back computer from a group buy. The instructions and product were first rate. The throttle response is better and the car is unquestionably quicker. Although I haven't put a calculator to it, my mileage has improved enough where it is noticeable. My fd computer was programmed for the 93 Octane we have in Houston.

The FD 93 Octane Piggy Back...

Did you do the mod yourself? Was the installation easy? How long did it take? Any special tools needed?

I am looking to get in on the same chip here just after Christmas sometime...

Yes I did it all myself. My car is only 6 months old (with a full warranty), so I was concerned with getting everything right. I researched just about every program out there before choosing this one. I had prior experince with a piggy back vs a reprogram on other rides. The installation was straight forward and took about 3 hours. The stock wiring harness is wrapped with black (cloth type) electrical tape which the dealer did not have. I found a roll at Grainger ($4?).
I have soldering equipment, but did not use it (as suggested in the instructions). Experience has taught me that high quality solderless connections are best, combined with adhesive lined shrink wrap. This holds up to vibration, moisture etc. better ,and will last a lifetime (and is easier to work with). I can give you an online source and the part numbers for everything (about $50 including 2 tools?). After completion you can't tell that I was ever in the wiring harness.

If you don't mind....

Please share the information if you don't mind... I am sure I am not the only one here who would like know!

The supply company I used is www.terminalsupply.com. To complete the installation you will need the following: (pg149) part# MWS-01-06S (3') - (1/8 adhesive lined shrink tubing), (pg2) part# AS-345 (1 pack 18-22 gauge solderless butt connector). I believe they may have the black tape to match the factory as well(?). It looks like part# FT ( pg153). If you do not have a quality crimper order part# WT-111M (pg242) and for a wire stripper use part# 1004 (pg 241). All of this is very reasonably priced and only take a few days to get. You will need a heat gun to shrink the tubing. They do sell them (pg246), but rather than incur such an expense hopefullly you can borrow one. Since in this application the tubing needs to shrink very little you may get by with a high quality hair dryer. If you were in an open area a match/lighter would do the trick, but you can't use it here.

Using the parts above will provide for a more professional installation than soldering. Soldering can cause wires to become brittle and subject to breaking under vibration (ever seen solder in a factory harness -no). Not only is the method better, but much more user friendly. Additionally, you can now just cut all the designated wires in the harness rather than some that it calls for scraping the insulation off of and tapping into. This again is easier, but most importantly will allow you to shrink wrap all new connections. Otherwise you would have to use electrical tape on these particular junctures. This is very easy and FD does an excellent job of describing the wires in detail. If I can be of further assistance let me know.

Excellent!!!

I am hoping for the week between Christmas and New Years... I will get in contact with you then... I understand exactly what you are doing, used to make my living chasing down electrical problems in boats... The way you have done it makes it look factory spec, nice and clean, easier to install....

We've done extensive testing and many months of development on this chip. 50HP is not going to happen, when we sent email to these companies ( as a consumer ) asking them to back it up. We then heard comments like... that was also with Euro Headers and fuel cooling, etc...

FWIW, a well developed program for the 4200 GS, Coupe, Spyder or QP can net you about 20-35 HP. It depends on fuel, aftermarket parts, and where in the powerband you're at. You will notice an increase in response and an increase in power, it's not earth shattering but it does make a noticable difference. For instance without the chip we could barely pull an E46 M3, after the chip it walks away and the torque is more evident as the initial roll on is much better.

Our instructions are fairly detailed and we're available by phone. If you can solder and understand the basics, you can get it done.
