Newbie 07 M45 Sport Owner...Flush the transmission and basic bolt-on Performance ??

[Jimmyz]

I just picked up a used 07 M45 Sport on Jan. 14th. I'm an LSx Camaro SS/Corvette guy who considered getting an 09 G8 for my daily driver but drove the M and was sold! What a great car! That said, I know zippo about these cars and what I need to do to increase performance with bolt-ons. Also, I'd like to know where I should go to do lots of reading on this transmission flush vs. drain?

ThanksJim

Just to save yourself the troubles and headaches from other members. Do a search in the search bar at this website on all of this stuff. There is not much to be had to gain more performance with these cars unfortunately. There are a few things that are emerging. Tuning is one of them. UpRev seems to be able to tune these cars. Though we have no feedback on the gains ...yet...but it is coming.There are currently exhaust kit available. Don't do a cold air kit yet. The ones out right now will give you intake sound, but you lose performance.

Welcome a board by the way!Get to searching!

Welcome to M45 Forums. Congratulations on your new car. With modifications, as I'm sure you know, you risk having warranty issues.

The car is pretty powerful, bone-stock. For now, you can only do Intake, exhaust & brake upgrades.

Since I never ever launch my cars, I consider "street start" ratings to be a realistic gauge of daily driver performance. The 5-60 (street start) between G8 GT and the M45 is virtually the same. M45 = 5.7 and G8 GT = 5.8Yet it gives you megatons of luxury & refinement! :-)

Cheers!

LOL!! I'm familiar with search feature and have been trolling for a few years while i had an 07 G35. That's gone off lease hence the slightly use M.

Here's one for you. I tried the on board self diagnostics feature and got a message something to the effect of "self diagnostics module is not functioning. When this happens, the Bluetooth NAV HD drive is hunting big time making all kinds of noises. Is this normal? My Bluetooth sucks in this car compared to the G35 to. Needs all the thing y'all talk about with the self diagnostics function. More volume, less back ground noise etc. Is this a warranty thingy?

Thanks.

If your questioning something working properly, then take it in to the dealer for warranty repairs. The worse they could possibly tell you is it is normal. Self diagnostics feature?? Maybe I haven't seen this on mine. What option is it under?

You're kidding right?

There's a sticky on this website that says the following: Secret Diagnostic Mode



The 'M' has a "DIAGNOSTIC MODE" that is not documented.

Follow these steps to enter [at your own risk] into the diagnostic mode.

- Start Engine [required if you want to see all available diagnostic options]- Turn OFF the Audio system- While pushing the SETTING button, rotate the radio's VOLUME control either clockwise or counter-clockwise 30+ clicks.- You will then be put into the diagnostic mode.- Use the BACK button to get to previous screens.

NOTE:Holding down the SETTING button and rotating the volume knob a 2nd timewill put the diagnostic mode into a more "detailed" state offering more options.

------

Diagnostic Mode - CELL PHONE VOLUME

One potential use of the diagnostic mode is to improve the sound quality of your cell phone.

- The diagnostic mode has an option "Handsfree Volume Adjustment".- The default setting for this option is "MED".- Setting the volume to "HIGH" may improve the sound quality of your bluetooth compatible cell phone.

------

Diagnostic Mode - BACKUP CAMERA

The Diagnostic Mode has an option to adjust the BACKUP CAMERA.

- Not that I suggest you do or try this but ...While cruising in your 'M', you can enter the Diagnostic Mode [see above] and go to the "Backup Camera" adjustment screen. When you are in this menu, the Backup Camera turns on. It's quite strange to see the traffic moving at such a high rate of speed both coming at you and going away from you. I'll just leave the effect for your imagination.
