I have my NA 13B so it starts ok in cold weather. It fires right up in -10ēC weather, but I am wondering what every body's cold map enrichment tables look like. I am sitting at 80% enrichment at 0ēC, or the freezing point, and go up by 5% every 5 degree drop. I dont know if this is excessive or not, but wondering what everybody else's is like.

Also, I am using the old style non predictive map Transient Throttle, since I have an S4 TPS, it reads 100% TPS for most of the throttle range. I do not have the Asynch throttle setup at all, when properly set up, should the values decrease or increase as the engine RPM increases? The base map has the values increase, which is what I think it should do, but I read that the Transient throttle is not needed as much at higher RPM's, and I saw an Asynch throttle graph for a different engine, and it decreased as the RPM increased.

 

I would get an S5, or full range TPS for you're car. And tune it with TPS and MAP( dual maps, 1 being TPS vs RPM, and the other MAP vs RPM).

And use map prediction mode!
