The only Alpha N base cal I see is for PRB ecu and when I upload that I get wrong cal for ecu error. Anyone have Alpha N cal for PRA or know what I need to disable to stop error? Thanks.

Ah okay so there are other tables that need the MAP signal. That makes sense. Thanks for reply.

Do you mean when using Alpha-N Throttle Position Sensor is only used for fuelling and not timing! I have a race engine and assumed I could use Kpro for a normal TPS based tune. With individual throttle bodies the MAP readings are close to useless even with a block.

So it is not possible with kpro ...

Thanks.

Do you need MAP sensor plugged into K-pro even if using pure alpha-N with ITBs?
If so is it just as an atmospheric pressure reading or does it need to be in a vaccum accumulator?

I guess my main questions is, when using Alpha N what does MAP sensor reading get used for?

Thanks

I checked through Kpro manager screens and it looks like on Vtec parameters page I can disable P0341 to get it to work. Anyone know of any other codes I could throw? Will a target vtec angle of 0 deg actually be 0 or will it take the -10 as 0?

"P0341 This error is generated if the phase difference ...

I have tried searching for this but havent been able to find answer so apologies if it has been answered somewhere else.

I have checked my build valve clearances and know that the maximum cam timing I can safely run is 40 degrees (20 at cam). I know other builders who remove the inlet camshaft ...
