    Thanks to AK330i. I exactly coded as below and it worked like a charm. Mine was a 2007 e92 335i. Saved me a few hundreds :)

    The only thing to note is after coding shutoff the car and give it like 5 , 10 mins to start picking up NZ frequencies. When I checked immediately after coding, I saw FM and AM disabled. After a while they came up automatically.

    These are the settings that I changed in the CCC idrive:

    Hey guys,

    Installed the following parts this week,

    • VRSF 7" Intercooler
    • VRSF Charge pipe
    • HKS SSQV4 BOV
    • BMS DCI

    and flashed the MHD Stage1 FMIC map. The car is pulling harder than before peaking about 17-18 psi.

    I am very much happy with the turbo spooling music from the DCI and the Pss -- Psss sound from the HKS. I was kind of worried if the HKS would be too annoying after a while, but no.. , I started getting addicted to the sound. As our cars are well insulated HKS was not too loud as I expected and I liked it. Will post some videos of how the bov sounds when the windows are up, down and at full and low throttles. Sometimes the HKS makes these double PSS sound due to its synchoronous design which is soo cool. I was planning on installing the purple fin earlier before I got it but I think will leave it like this.

    The VRSF 7" Intercooler was spot on, had to cut the plastic shroud though. The VRSF Chargepipe was a direct fit like the factory C clips in the stock chargepipe and was easy to install. I got the VRSF lower charge-pipe as well so everything was a good fit. Tiago from VRSF is a helpful guy and his customer service was excellent. The products came well packed and there were no damages during shipment.

    Need to get the BMS Oil Catch Can and have the Intake valves cleaned to complete my Stage1 Tuning process.

    I talked to Ray from HellBM who gave me a quite reasonable quote for having the Alpina Trans flash installed. Will be doing this next month.

    Cheers..

    Another MHD tuned 335i , great :) and congrats . Mines an AT by the way.

    If it was me, I will wait until I upgrade my fmic, before using the fmic+1 map, especially as it is getting hot these days.

    Fmic+1 tune has a bit higher boost psi level and i suspect that it may stress the engine.

    My year and month (2007 , 08) has a welded diff unlike the bolted ones in the others, so getting an LSD installed is going to be a bit difficult. I will worry about this later after i go fbo.

    I have heard good reviews about the Alpina.

    Thanks.

    It was the coil. After I replaced it my car ran good. Scanned for error codes and the 2FA3 disappeared. I too plugged off the recir valves to get the blow of valve sound. Not really loud but sounds nice.

    The tune was definitely better than the stock and worth the money. The 2nd gear was kind of conservative , did not feel much of a difference but from the 3rd was where I felt the car getting pushed harder. The gear changes and the power delivery were smooth. The stage 1 91 oct map gave a max boost of around 14 psi.

    I use BP 98 for gas and I was wondering if I should use the Stage 1 93 oct variant map, if that would give me a better edge.

    Looking forward to get an aftermarket charge pipe with bov and a fmic during summer.

    I will be logging values and might post in the forums for feedback.

    Having fun with the new tune at the moment :)

    Ive been getting a lot of PMs asking about the MHD app so best if i update this thread with my comments.

    With the app you can flash OTS maps which are by all accounts very safe and conservative. You can also flash a custom map or backend map to use in conjunction with JB 4.

    If you are just starting out its better to get MHD as its cheaper than all the other options, easier to use and is constantly being updated. Cobb has ceased new development of their maps. And arguably its better than JB4 as its not a piggyback but a ecu flash.

    MHD is tied to your phone, google account and vehicle. So if you ever sell your car the app becomes useless to you. But, if you purchase on a standalone device and google account you can onsell it with your car. Cheap android devices are easily available.

    I bought cheap ebay cables which worked for me. No guarantee they will for you too but these are the cables I got:

    http://www.ebay.com/itm/251698392855

    http://www.ebay.com/itm/Micro-USB-Male-To-USB-2-0-Female-OTG-Adapter-Cable-For-Samsung-Galaxy-S3-S4-Mini-/151532877345?hash=item2348103621:g:sCUAAOSwGzlTxcKg

    I recommend you get a 3-way OTG cable not the single. That way you can charge your phone through the USB port at the same time you are logging.

    When first flashing I had a charger hooked up but its not necessary if you have a good battery.
    Before you flash backup the ECU as you cant do this later. Or you can just flash to map 0 if you want to go to stock if you dont have the ECU backup to flash back.
    Once the car is flashed then its time to start logging. Go WOT from 2500RPM in 3rd gear then shift to 4th at 6000RPM and keep going for a bit (do this discretely as you will be going well over 100kms at 6000RPM in 3rd - i think 160 or so). Upload results to datazap and post on E90forum for feedback. Using a higher boost map will show up all the weak points in your car and you are very likely to get limp mode / check engine light. MHD can read codes too which will help.
    In my case I had vacuum leaks and boost leaks. Replaced all the vacuum lines and cleaned out the diverter valves and disconnected to get a bov sound.
    Im running the Stage 1 FMIC map although I dont have a FMIC. In summer will either get FMIC or use a less aggresive map. This map targets 15psi (stock is 8 psi) and totally transforms the car.
    Heres some old logs I took using the St 1 FMIC map - im comfortable using this with no aftermarket FMIC as the IATs are nice and low and not getting any timing corrections.
    Any questions id be happy to try and answer them. Enjoy!

    Hello Drew, I noticed that my boost was somewhere around negative -8 psi at idle and only stared to go positive around 2k rpm in second. Is this something similar that you noticed in your car after the flash ?

    Finally got a chance to flash my car with the MHD stage 1 map (95 ron). Below is my experience. As I am new to the tuning world everything was a learning to me.

    Most important thing before you flash: Make sure your battery is healthy, if not hook up to a good battery charger ( min 8 amp).

    I did not realise that my car battery was very weak and the 12v 4 amp Battery Charger (snap on) was not sufficient enough to maintain a constant voltage. As a result the flash ended up with a write error and my car was left inoperable. My car did not start and was showing hell a lot of error codes.

    The K+Dcan cable nor any of the OBD2 diagnostic scan tool no more was getting connected to the ECU .

    After reading a few forums I realized that my ECU must have gone to the recovery mode and not letting any of tools to get connected to it.

    I then disconnected the negative terminal of the battery for like 5 mins , connected back again and then tried connecting my cables. Thank God that I was able to connect back again.

    This time I changed my car battery to a new one and then used a better battery charger. The flash went good and got completed in 18 to 20 mins.

    Was exited and wanted to see how the car pulled after the flash. To my bad luck the minute I was WOT on the 3rd gear around 4k rpm, I got my engine light on and the car started shaking and ran very roughly. I used MHD to read the codes and saw that I had a misfires on the 5th Cylinder.

    In addition to this I also got a 2FA3 - (Code Missing) which I have no idea what caused. I have been reading forums and did not get proper diagnostic reason.

    I am planning on changing all of my spark plugs today ( and check the coils on the 5th cylinder). Hopefully the 2FA3 goes off after that.

    Awesome mate. I just bought one this week but it's the sedan and I love it. Like you I want to get used to it a little more and get the crew at bm workshop botany to give it a once over then I too am looking at the mhd.

    Please do let us know what your feedback is on the mhd.

    Check out the review posted by Drew.

    From what i can see atleast the non aggressive tunes sound safe. Will keep posted on the results once i have the tune myself
