I was the lucky winner of the MHD raffle. First a big thank you to Martial and Spoolstreet! Between my two 335s I have used jb4, cobb, bummerboost flash and MHD but only for a burger backend flash. I want to say this a completely unbiased and honest review. I was very excited to see how MHD would perform stand alone because I have had nothing but issues flashing my 2007 335i kline car. The cobb OTS maps had horrible throttle closures. The only solution was to have the car protuned. As for the bummerboost flash half of the time it would have an error flashing and I would have to rewrite sometimes multiple times. Pretty sure this is a kline only issue. Now on to the MHD! For those who don't know everything is done on an android device. In my case, my phone. I installed it on my 2007 FBO/GC lites manual trans 335i. From the time I downloaded the app everything has worked flawlessly. My stock map took next to no time and the initial write took a hair under 17 minutes. When making small changes such as wastegate rattle fix or raising the idle the flash takes right around a minute. Changes such as raising the idle, adjusting for wastegate rattle, and exhaust burble are very easy to change. As for performance, the car runs excellent. I was pleasantly surprised how smooth the car ran. It feels like a stock car with a ton of power. As for the logging it is very straight forward to use and works perfect! You can change the layout and what you want to see in real time. This is a big upgrade from when I was using my cobb and only able to view one value at a time. Another feature that I have used a lot already is the graph a log feature. It brings up a datazap like graph for your log. It is very easy to instantly look and review a log. It is very smooth and easy to use/see even on my phone. I would not hesitate recommending MHD to anyone. Especially if they already use an android device. The car runs flawlessly and I am amazed how smooth and glitch free the app is. I will upload a few screenshots of the logging/graphing a log for those who don't know what the app looks like. If anyone has any questions please let me know. Thanks again Spoolstreet!
