F80/F82/F83 M3 and M4 (2015 - Current)
F80 BMW M3 sedan, F82 BMW M4 coupe and F83 M4 convertible forum. This 5th generation M3 and all new M4 features a 3.0 liter twin turbo engine (engine code S55) 425hp and 406lbs of torque! Heavy use of light weight materials makes this generation lighter and faster then the outgoing E9x M3.

Dinan ECU for Competition Package

Hello, I am new to the forum. I just received my Competition Package M4. Has anyone placed a Dinan ECU upgrade (any stage) on their Competition Pack M3/M4? I only see specs for the M3/M4 (Non-Competition Pack) on the Dinan website. I want to know if there were additional gains starting with the Comp Pack vs standard M4? Cheers!

Dinan performance gains w/ CP

If you check the website carefully, you will see that there is a different spec ECU upgrade package (stages I, II & III) for comp. package cars. The resulting dyno curves (torque & HP) yield about the same bump over stock as for the non-CP cars. Of course, since you start with more, you end with more.
My 2015 M3 (no CP available in that year) has the Dinan stage III upgrades (also exhaust & suspension). It is substantially faster than stock. The stage III changes (with heat exchanger) were the most dramatic.

Stage III. Wow! Do you have noticeable turbo lag with stage III or is the boost on/off progressive? I'm not looking for a straight line drag monster. I prefer something with predictable and progressive boost mid corner for track days, etc.

Torque delivery remains progressive and easily modulated on exiting corners,but there is noticeably more of it. With traction control off a second gear (6 speed stick) roll-on at 2,500 will break my Pilot Sports (oem 275/35/19) loose if done aggressively. As one would expect from the torque curves shown on the website, torque is up significantly and it comes on sooner.
I would think that the heat exchanger would be a valuable upgrade for track days because it would reduce the heat sink effect associated with repeated use of full boost.
Turbolag is no more evident than with the stock M3/M4.

If any company produces a near stock type delivery it's Dinan.

Its not an ECU its basically a glorified boost controller like a JB4 with a tad more monitoring features (which now that the ecu is open I believe JB4 has caught or surpassed the tad more monitoring dinan got), and a warranty... This is not a fully overhauled "tune", in the sense that you buy a cobb for a 2009 N54 335i and flash a file over it.

Its been awhile since I did testing on the Jb4 for my m4.
