There is info about installing it on m44 wiki

Considering the price of Ostrich and Cobra emulators, IMHO it's kinda pointless...

Hello everyone
After installing the broadband controller, I noticed that at 1700 and 2300 rpm, the mixture becomes poor up to 15-16 afr, sometimes a detonation is registered after that. If anyone has encountered such a problem, can you tell me how to solve it?

We kind of need to know a bit more about the condition of the engine currently. What mods, etc.

Hi,

I have done it! It is a perfect way of getting there quickly since it is live tuning, and best of all, more accurate for all your tweaks. I recommend it!

A good way if you also plan to tune other cars with that ECU feature. When done, just flash that bin to a standard ECU.

Let me know what you need.

Send me a mail ([email protected]) if you want guidance, pictures, pinout etc.

Hi, my only concern is the price of Ostrich and CobraRTP emulators.

200USD is too much for just an emulator

What loading is the engine under?

You have the ability to tweak your fuel settings, etc, so why not add a little bit in that zone?

I added fuel in these places, it didn’t help, I’m trying to change the lambda regulation.

So, are you using VAST's WBO2 modulation bin?

Have you done the calibration with the 14point7 WBO2?

Where is your O2 sensor located?

It's been a minute since I've looked at the map in my modulated bin.
