What ecu r u using ?
Motec M150, with some help from a C125 and PDM30. The "Build" firmware for the M150 isn't available yet, so I'm stuck being patient.

One ECU will run everything:
  • Engine (DBW, VANOS, Fuel, Ignition)
  • Transmission (Automatic 5 speed)
  • Pumps, fans, and ancilary electrical
  • Boost Control (Anti-phase)
  • Water Injection
  • Methanol Injection
  • Nitrous Injection

I think my last count was something over 150 I/Os, and over 1000 channels of data available for logging.

Have you been watching IAT vs Water Injection when logging?

Yes I have monitored AIT with water. I found it has no effect. The cooling is done in the cylinder when it vaporizes. 50/50 meth does change the ait so u get advanced timing automatically so I don't have to do as much with the timing only a few degrees. More testing to be done....

Latest Dyno Comparisons of Pump and Water injection. U can see the water injection HP falls off high RPM (exhaust limitation) and the Pump Gas keeps the power up top. Water makes 671 Peak Wheel HP while Pump Makes 633

The 50/50 is going to be much higher based on how the car drives. I'm adding a 3 inch electric cutout wired into the AEM to activate over 5 psi of boost to solve high boost high rpm drop. Just waiting on a dyno time slot to see the actual numbers and I'll post the comparisons of pump, with water, and 50/50, then the same but with C16.

I've reconfigured my race switch to be 50/50 meth when on, and water when off. I also use it when I'm butt Dyno tuning. I have it increase the timing and pull fuel and by 1percent increments. So when I dialling in a tune on I just turn the switch and do another pull. If it holds then I connect the computer and set the tune and do the process over. It just saves me time and more practical when I'm tuning alone.

My next modification for the motor involves porting, polishing & port matching the cylinder head and fitting aftermarket retainers, valves and springs. I'll be doing the work myself on a head I just purchased. I used to do porting on small blocks and had fun with it and excited to get started. I'm just waiting on the BMW cam, valve tools and the head, should be here sometime next week. The goal is to have more durability, to be able to run more timing and possibly more boost as a result of higher flow with hot spots removed. Then ill Dyno it and see the before and after comparison. It will be a while as it's only one of my long Canadian winter projects.

Modified / Simplified the meth Injection. I found the there are many connections that can leak over time.

Here is the relocated meth filter. This simplifies the routing reducing the connections and also making the filter more accessible and not having to remove the bumper. Its not as pretty but I,m more concerned with function / reliability.

I'm also considering at some point putting a meth tank in the trunk to get it out of the heat. I will also add a purge switch and valve to simplify priming the pump.

Dialled in the hi boost tune today using a whole tank of 50/50. Settled on 25psi @ 11.5 AFR (achieved by pulling fuel @7% and increasing to 10% above 6500 without 02 FB in boost) with 2.5 degrees of timing advanced tapering to 2 above 7300. Runs fantastic... 3rd gear with hot tires is beautifully spinning throughout the whole rpm range into 4th...having a riot just hanging on....

I stayed conservative until I get to the dyno... Intake and engine temps r all good... Interested to see the actual numbers. Virtual dyno run on my logs says 756 rwhp 696 rear torque. Also 11.5 Afr with 50/50 is really around 12 - 12.5 gas Afr which is prefect for power. Timing can be increased but I like the margins I have. Tune was tested fully loaded car with fuel and in 6th up hill to verify no knock. It performed repeatedly without issue.

Very nice...can't what to see the dyno #'s. Take video.

Now all you need to do is go spank some P800 GTR's

buying a used HPF M3

I am really enjoying the car now with it running beautifully. I have spent a lot of time lately dialling in my traction control and VSS based boost... Since the 50/50 tune with about 650+ torque I am needing it big time to get 3rd gear to hook, never mind 1st and 2nd.

I started a new thread for tuning 50/50 if anyone's interested

Got 3rd gear hooking on high boost today. I managed to tweak the waste-gate duty cycle to get my boost down to 15.5psi and transition up to 25psi as vehicle speed increases combined with tinkering with the AEM Traction Control its really smooth. Soon I'll be ready for the drag strip once I get 1st and 2nd dialled in

Made a few more adjustments to the VSS based boost control... Trying to find the optimum power for each speed with water/ meth. I have been able to adjust it so that I have Traction Control off and have traction in 3rd on the limit of adhesion. I modified the My tune for more resolution in boost ( 2.5 psi increments above 15 psi all the way to 27.5psi) to fine tune the timing etc for max power under the curve and grip... There was some overlap / redundancy in the map that allowed me to make the changes within the 16 breakpoint limitation. Thanks to Mert for suggestion and his time . more testing to come

I really am grateful for the support and knowledge that's is shared with fellow enthusiasts on the forum. I,m not a big fan of keeping the knowledge a big secret hence why I like to share what Ive learned.

Exhaust Cut Out

Received my low profile oval Exhaust Cutout today. Found a great place to mount it without loosing any ground clearance ...it mounts on the opposite side where the Wastegate merges into the exhaust. This will allow for the most flow and still have the car a sleeper with stock section 2 intact. I will have to move the 02 Sensor so its before the cutout... I don't mind moving it because it's mounted straight and it should be on and 10 degree angel so moisture doesn't rest in the sensor throwing off the numbers.

I had noticed since owning this car when checking the oil it would take several minutes after shutting off the car before oil would reach its mark on the dip stick. Not sure if any other HPF owners have experienced this? I took a look at the oil return line from the valvecover to the oil plan. IMO it looked too small to move much oil. So I replaced it with the biggest steal breaded hi temp hose I could fit. I now can shut the car off and literally pull the dip stick and the oil is at its mark. Tells me there was a bottle neck on the return and is now resolved. ( it is possible the return line had some sort of restriction / blockage) This fix will save pushing some of the oil out the breather as well as the OEM oil separator will not get over loaded.

Had my electric open dump fabricated 2.5 x 3. 5 oval coming off of a 3 inch streight pipe from section 1 all the way to my muffler then It exits straight back just after the diver side half shaft. u can't see it which is nice and stealth .. Man it's sounds good and pulls hard and gets up on boost a lot quicker....I also dialled in the tune with a bit more boost and the motor really likes it.... running 20psi base and 26psi with 50/50. Added the CSL SMG tune for kicks as well and that makes the car shift amazing and quick...

All my parts for my SMG conversion r all here except for my custom stage 4 clutch which FSR is working on with Southbend as we speak... Because of the almost 700 foot pounds of rear wheel torque it needs something more robust but still tame enough to drive on the street. I'll spend the winter months getting that done.

I put my radiator swap on hold until a newer version comes out sometime in February. So I did a rad flush, wetter water and installed Motorsport thermostat. I did a run and my water temps r down 20 degrees from 195 to 175 at max load and rpm... I found that with the 720+ rwhp 650+ torque that I was seeing with the 6766 and 50/50 temps were higher than I felt comfortable. They weren't bad but I wanted them down. I'll be doing another dyno session with the open dump and post the results.

I created another thread for tuning 50/50 water meth and it has my most recent dyno numbers.

Good luck with the conversion. I wish you would stick to SMG, work on it, and come with a solution for the E46 platform.
