Quick newb questions
Can someone explain what the difference is between the tuners that are offered by companies like Dinan, Turner, Burger vs. an actual software flash?? Is the difference "piggyback" vs "ECU reprogramming"? Does a piggyback tune just trick the ECU? Wouldn't an ECU flash always be preferred? I just traded my 2013 GL450 and I know Dinan offered a service where you could mail them the ECU, they flash it, mail it back to you and suddenly you have the GL63 engine... Is this possible with the F80's? Are the JB4 type tuners temporary solutions until an ECU flash is released? Lastly, what's all this business of "STAGE 1, 2, 3"?? Lots of newb questions- would appreciate a quick course on what all this stuff means. Thanks!!

Stage 1, 2, 3. Normally as additional parts come out, more adjustments can be made to make more power. IE: Upgrade Turbo, Cooling, Exhaust, Plumping. Most tuning can take this into account and make more adjustments for again more power as you upgrade things. Last edited by DocWeatherington; 10-07-2014 at 07:26 PM.. |

No Flash at the moment.
Tunes: Alpha N Dinan JB4 Best bang for the your buck.... JB4 None does have a warranty with BMW Dinan has a warranty but only with Dinan. So its a "Dinan Warranty" I have been in many cars that have JB4 and (1)alpha N and I would choose JB4. Haven't been with Dinan or will ever choose to but there is a review regarding its tune. I believe the majority have JB4 over any other. Tested the Alpha N and the power isn't there. So far JB4 has the highest WHP out of all the tunes so far. After putting over 4k miles on a the JB4 and 1k on the alpha N (another M3 sedan) I would say that it offers the best performance wise IMO. Other peoples reviews are welcomed.

How does a JB4 tune affect BMW's handling of the warranty? Knowing that Dinan is a company that works so closely with BMW and Mercedes- and having read on Dinan's website that they have been developing the M3/M4 tune for two years, it strikes me as odd that BMW wouldn't just grant them exclusive access to the software code to offer a proper ECU flash. |

if BMW knows about the JB4 they can void your warranty, same can be said with most any modification including Dinan. The difference with Dinan is that Dinan should step in and pay for the repair.

Many Dinan distributors are also BMW dealers.

Well this certainly turns me off to the idea of a JB4 tune! I know when I looked into the Dinan flash for my 2013 GL450, the claim was that there was no impact on MB warranty...

Skip the tune for now. Check the forum after 2-3 years and there will be a lot more options available. I wouldn't want to beta test new tunes on my first model year car.
Car already has plenty of power in stock form. |

Dinan tune is warrantied through dinan but only last two years from the purchase date. Dinan will take the car back and fix the issue. Personally I would have gone for the flash but who knows when that will happen. There's always gonna be a faster car but driving stick isn't fun lol
