How To: Add Pressure Input for PC-V

I have the F/L switch at 9-9-9-3-1-0 if memory serves. I may be changing that to all zeros and just using the PC-V for the MAP based fueling though. Essentially inverting the table so it’s F only tables from 0-1800 RPM and then F tables plus PC-V speed density from 2000-8000. This is achieved by setting the AFR target tables below 2000 to zero.

This I do because so don’t get good data at low RPM the wideband is kind of challenged at low load and low rpm with my exhaust setup and reversion screws up the AT function.

We’ll see, will follow up with results this weekend when complete retuning using this method.

This should also make dialing in the bigger injectors easier.

Hi Claviger

Firstly sorry to hear re your gearbox, not caused by the Quickshifter? as I was thinking of fitting one to mine a while back but never got round to it. Your recent posts got me thinking about it again.

Quick question on above where you set the AFR tables to zero below 2000. This on the Tune ECU or PCV? I'm thinking its the TECU so the PCV and AT do the work?...

Thanks in advance.

On the PCV AFR targets - Otherwise the AT will totally over correct.
