Actually there is, I picked up a Z4M coupe after moving my M3 on and i've been slowly working through the ECU on the Z4M, so far I've nailed the following:

- Recalibrated warm up lights on the cluster
- Secondary Air Pump disablement / removal
- Cat efficiency DTC removal for decats
- Launch control
- De-limit
- Rev limiter recalibration

The remap is currently still in development, but from my datalogs things look promising.

This is awesome, great work! Good to see someone getting stuck into our ECU's as not many options out there

Any update on this Martyn?

Yeah, I'm still developing and testing on my own car daily.

I've been developing an AlphaN tune alongside the MAF based tune using one of my IAT bungs, meaning I can switch between a MAF based and MAFless setup in a few mins.

and installed

I've also developed a plug and play loom for the MaxxECU standalone ECU & the Z4M, it utilises the factory widebands, I also cracked the EKPM canbus so it will happily run the fuel pump via CANBUS, the only modifications required are an external oil temp/pressure sensor and the use of smart coils rather than the stock one.

It looks pretty crude but works.

Running the standalone allows me to test vanos changes instantly without having to worry about logging/flashing/logging/flashing etc. It also means I can switch back to the MSS70 very quickly when needed.

And an a prototype enclosure to protect the wiring. I need to refine this to ensure it fits in place of the original MSS70.

Quick video of it running via the MaxxECU.

I remeber some French guys who had been running an Aim infinity 8 but not sure where that went to. I guess the benefits are similar...? flat shift, launch, traction, lots of tuning options etc? Very interesting.

I'd love to try your alpha-n on my car when it's ready, I remember you saying there was a lot of timing being pulled on mine.

Any time line for the standard ecu tool release?
Cheers

I have a PNP Infinity that I ran on my E46 M3 but obviously the ECU plugs are different. I may create a patch harness for that too.

Benifits of the standalone, specifically the Maxx are that it will happily control the E9x DCT trans. It also means you get the additional features like you mentioned.

I think there is plenty left on the table for your car Tom.

No release date yet, I want to get everything nailed before I automate the changes in software.

In the words of the Project Farm guy on YouTube - Very Impressive!

Looking forward to the tool when it is finally released

Very interesting thread. Excited to see where this goes.

Just been out to test overrun pops/burbles, enabled via the sport button. Not my cup of tea, but it's always something people ask me for!

Would that feature work with an Alpha N map on the OE ECU?

Martyn · Post by **Martyn** » Thu Apr 28, 2022 5:22 pm

Sure would, providing the ECU is not locked, the testing i've done is using the stock ECU and my own AlphaN tune.

I'd also recommend decats for the overrun unless you don't mind your cats taking a beating lol.

You can read/write to the ECU using MSS70 Quickflash. A tune flash takes 60 secs, which is alot faster than the Kess V2 clones!
