How do I log TP values

[elpiar]

I am in the stage now I need to tune my ECU. I have the calum realtime board and it's been working great. The only thing I need now is the TP values logging.

I heard nissan data scan is able to do this. What are my other alternatives?

If you dont have a wideband already, Zeitronix WB setup owns for data logging. It will allow you to save unlimited ammounts of data on your laptop. RPM/AF/TPS/BOOST/EGT/ and one user imput, 0-5 volt. You can do knock, or MAF readings, or whatever. I love mine, check out their website.

No no actually what he is talking about is "Theoretical Pulsewidth" it is what nissan ECU's use for determining fuel delivery and is an axis on the fuel and ign maps. It could compare to a load value....but is far from it.

It is tricky, there is a formula....I believe datascan has incorperated it into their software......other options are.....an emulator that has a trace feature. Or finding the formula on your own and logging all the information needed to plug into the formula and finding TP.

P.S. If you go to the chat on my webpage I can talk with you about it. I offer free tech support and tuning information to my customers 24h a day. You are not a customer of mine but since you have gone with calum's hardware Ill help you out....I deal with calum alot.
