i was having a lot of trouble with my car idling on the MSPnP (mk1 1.6) when i removed the AFM for some reason so i followed the guides on here, to get it all set up nicely under warm-up mode and then going back to closed loop control and that's all fine - but my VE table requires 52% around the idle cells, whereas the 'stock' map has around 33%.

Until i can fit my LC-1 what's the best way to scale the stock VE map given this difference? shall i just leave the 100kPa line as it is and scale accordingly?

i'm running stock injectors so have not adjusted the req_fuel field, it's set at 13.4

Skinny, you'r really going to struggle to tune without your wide and installed. Do that before rescaling anything, your shooting completely blindly otherwise.

Not tuning AFR with a wideband is a dangerous/foolish decision.

skinny, I believe that megatune has a function to rescale the fuel table based on a new req_fuel. That would be the easiest solution. You can tune with a narrowband, but it's time consuming, and you'll never get it very accurate. But it's not a good idea if the motor is highly strung or turbo'd. But near-stock it's ok.... Before I purchased a WB02 I tuned my miata with a narrowband and MLV. After installing the WB I checked out the tune, and it wasn't that bad. Too rich, but safe.

I had the same experience tuning with a NB sensor on an N/A engine.

But Skinny has a UK only BBR turbo car, he needs to fit that WB pronto.

Ah, yeah, don't fool around with that . I messed around with one of the new MTX-L's from Innovate... it seems like a nice replacement for the LC-1. Much easier to wire up.

ok thanks, i'll see if i can figure out how to hook up the LC-1 this weekend, and stay out of boost in the meantime!
