Maximum PSI E46 M3 turbo kit updates - 9/1/13

Hi Guys,

We have been pretty quiet on the forums, however we have been doing a lot of testing for the further upgrade paths for our E46 M3 turbo kit. There are 15 cars on the road with our E46 M3 turbo kit as of today! Three of those cars including mine are running stage 2 software with switchable maps. One kit is running stage 3 software/hardware! We have kit number 16 shipping out tomorrow to our first Canadian customer.

Stage 2/MS109 switchable map development:
As I mentioned previously, we now have three cars running with Stage 2 Switchable map software in "beta" configuration. I have been putting our shop car through the wringer to determine the limits for our stage 2, stock motor software. Things are progressing nicely, and I hope to be able to release the stage 2 software officially as soon as possible. Here is a nice video of Karim's stage 2 car shredding tires at a recent drift event:


Stage 2 E85 evelopment:
Once the Stage 2/MS109 testing is completed we will install the rest of our Flex Fuel conversion hardware and begin testing on my car with the stock internals. I was hoping to be further along with this, however there were other pressing items that needed to be addressed beforehand. We will keep everyone informed as things progress.

Stage 3 - built motor, pump gas:
We recently finished our first built motor car and it is tearing up the streets of NJ! It makes me want to throw a low compression bottom end in my car right away and crank up the boost. The 6466 and pump gas power levels are pretty wicked. We will be putting up a separate thread with pics and dyno numbers very shortly.

SMG cars/stalling issue:
We have sold six SMG kits to date including the kit that we raffled off at MFest this year. We have had very good feedback from the SMG cars aside from one common issue/complaint. The SMG cars will sometimes stall while coming to a stop and returning to idle. We are currently working on calibration revisions to eliminate this issue, however all of our SMG kit owners are located in the midwest or west coast, or they are their daily driver and can not be without the car for an extended period. I was hoping we would get a customer local to us in NJ, or local to Nick in southern Florida that had an SMG car and would let Nick final tune the car in-house at his shop in Florida however it hasn't happened yet. I am now asking for anyone interested in purchasing an SMG kit to contact us at Sales@maximumpsi.com. We will work with you on a discounted price if you are willing to let Nick to finalize the SMG software revisions in Florida using your car. Email or call us for details.

Fuel pump controller issues:
We have vehicles like mine that are driven long distances and put through to the test daily, and we have other customers that use their cars on the weekends or to go for a nighttime cruise. We had a few sporadic incidents with "fuel pump failures" on long trips that led us to look into the issue. We discovered the fuel pump control module on only small number of cars was getting overloaded with extended trips causing the car to shut off until it cooled off. We have since come up with a retrofit for current kit owners, and it is part of the kit for future installs.

Thanks again for all of your support. 2013 has been a dream come true for myself and Maximum PSI. We look forward to providing big power, OBDII compliant turbo kits for years to come!

Mike Radowski,
Owner, Maximum PSI

I'm not sure you will see another kit giveaway anytime soon. We took a beating on ticket sales, but the winner got a hell of a deal on the kit! He sold it for a nice chunk to another member who just had it installed at Castro Motorsports in CA.

Does your car have a full S54 harness/DME/etc? We have yet to do a kit on a S54 swapped car, however it should be doable especially if the car is already up and running correctly with the swap in N/A form.

yea i assumed the giveaway was a one time thing.

Yes my car has a s54 DME and i wired in all the needed m3 stuff (EKP fuel relay, drive by wire, DSC, ext.). I built it planning to maintain everything an m3 has and NO codes. as of now its not running, i need a few more small parts. when i have it up and running ill be sure to drive down and check out your shop

I can barely wait to get to my kit! It feels kind of cool to know that I'll have the first kit in Canada.

A big thank you to Luke and Mike who were both very helpful in providing information about the kit and getting it ready for shipment in such a short period of time. They were not only very quick to respond to my questions but were also very accommodating to my situation and I greatly appreciate that.

I'm definitely looking forward to the stage 2 E85 development!

I wouldn't send anything to MaxPSI currently if you have an SMG car. I can't speak to 6 speeds, but my SMG turbo dies at least twice a day on me when I am coming to a stop. It can be VERY frustrating, as you can imagine. Even if it doesn't die, I can see the revs drop about 3-400 RPMs on other occasions.

I do plan on doing a six-speed conversion next year and hopefully that I will solve the issue permanently.

At least Mike is being upfront about it in this thread.

Good to see an update on this kit. Sounds like there are some growing pains in the kit and I am looking forward to hearing about improved reliability for us SMG members.

M-F 8-6pm. Best bet is to shoot us an email if you can't get through the shop phone
