Thread: How to make your fuel and timing maps AKA "TP/LOAD" scales

This log shows my point pretty well.


You go from 4,600 RPM to 6,500 RPM. Pressure stays rock solid at 6 (psi?).
Yet TP goes from 88 all the way down to 65.

I guess you missed this part I wrote

This is a stock NA MAP sensor here although it will still read a little bit of boost, but reading boost isnt as important to me, but knowning when I hit zero vacuum/zero boost is for now, ofcourse later i'll be installing my GM 3bar map sensor so that I can gain higher resolution up to 20psi if need be, this one in this log below wont read past 6psi but thats not important for what im teaching/showing here.

BenFenner you really show a lack of experience in tunning, stop approaching this like a lawyer looking for little things you can prove, like I said there are glitches take off your tunnel vision glasses and look at the larger picture at hand.

I can see I've confused things.

Call me a skeptic. I want to believe though. All you have to do is show me a graph or a log where pressure stays nearly the same throughout a large RPM range and TP stays nearly the same. That's all it will take to make me a believer. Until then, I'll still operate under the assumption that TP follows the torque curve, and not any pressure/load curve.

Give up Ben... It is just sensor issues and noise that makes all the data he posts inconsistent to what he says.

Ben you wont win this one against me because im right, go throught and entire log and marry up every single TP with every single correlating pressue and you will see how it works.

But dont go thinking X TP = X PSI on your car or anyone elses car, its all different, TP is what you should be changing to make your MAPS, dont rely on automatic TP adjustments they only get you in the ballpark, I get you in the strike zone.

Post the excel sheet so he doesn't have to type it out to look at it.

You can easly use excel and do conditional formating to highlight and or sum the average of whatever pressure you want and do to find the value of TP that correlates with what value of boost.

*facepalm*

Right....

Please post so he doesn't have to type the data into excel. Hell even copy and paste the columns into a post.

It wont upload the .csv
