The piggyback unit is a physical add-on and essentially sends modified signals back to the stock ECU. It utilizes separate software code to derive the signals that will be sent to the stock ECU which 'trick' the ECU into increasing performance.
Dinan's approach would appear to be providing modified ECU software. So they essentially take BMW's code and tweak it then 'reflash' the code into the existing ECU. Here's a wiki on flash memory: http://en.wikipedia.org/wiki/Flash_memory |

I don't understand why anyone would prefer a piggy-back unit to a reflash. (bmw "approved" reflash)
$2k seems cheap to me. Re: Vishnu, I'm hesitant to do business with someone that has so many vocal haters. No clue what happened to the Z8 guys. Off to research that right now. edit: hmmm so the only z8 issue i found involved methods of installation of headers in the z8. not software related but interesting to read.

from what Ive herd your are very correct. also with all the extra power I'm a little skeptical whats guna happen when you go to the dealer with broken tranny. and BMW wont certify a previously owned dinan car so I wouldn't try the dinan flash if your leasing the car

With all of the 1/4 mile junkies/street racers on e90post running tunes (and even race gas, even a few more with drag slicks), there would be quite a few blown tranny threads by now. |

I would speak with your advisor about it before doing anything if you are worried about the warranty. It comes down to c.y.o.a. If your relationship is good and they know what you are doing or if you let them do the install you are in much better shape. A friend of mine works for a BMW dealership and has a 335 coupe. Its still a virgen though, no mods. The techs have been to BMW schools where they plug in BMW flashes that put out 350+hp and similar torque. I wouldn't be surprised if we see a ZHP version in the next couple of years. The hardware is stout enough. If you are asking for a BMW sponsored written warranty on non BMW mods you will not find one..... Hell they won't warranty damage from radars and auto starters!!!

from what i know about toyota factory warranty is that if it's not a toyota FACTORY defect then it aint covered under warranty, if toyota didn't make the problem then why should they fix it?

I would think it woudl be hard to believe that Dinan would release seomthing that factory parts couldn't handle as they would be fronting the cost for those who broke those parts. I am sure they have done their home work ..

What is the replacement cost (engine price and labor) for a factory new N54? I predict that Dinan won't be replacing or paying for any motor that is destroyed after installing Dinan's sofware. You assume the risk; you are on your own. |
