TPS experiment
If anyone has experimented with the tps voltage feel free to post your opinions.....
**All voltages were measured by a Fluke 77III multimeter**
I originally had my tps set to .45 and throttle response was fine but bogged a little and made taking off with a 8lbs flywheel and stage 3 clutch tricky ..but manageable ...idle was set a 900 and all ran well.
After 2 weeks the bogging was getting more noticeable so after checking the tps voltage today (2.5 weeks from initial setting) it was at .38.... WTF??!!
So after checking my friends honda (.49) and reading a few articles I decided to try it out at .45 and as close to .50 as I could get it without going over...
Every time I did search, I more often than not found .45 as a reference, to include one post written by myself quoting information I had read on the net.
And of all the articles I had read only one suggested that it be as close to .50 as possible and this particular article cited the helms as a refference..So I figured what the hell..
Well there were two significant differences in the two setting from what I noticed at the .449 setting the idle (900 rpm) was slightly smoother but the minute bog was still present at when I pressed the go pedal........Now the .497 setting had a slightly rough idle (still 900) but the bog was gone making the action of accelerating from a stop significantly easier.
Being that I have a pretty annoying stop and go drive to wotk every day I chose the .497 setting for the sake of making it less of a headache...but I still have to take more time driving it to make a real good evaluation (I only drove for about 30 minutes with each setting under the same conditions)
Here are some questions for you brains out there....
1) What is the setting that "Helms" recommends?
2) What exactly is the tps signal used as by the ecu?
3) Does the TPS signal directly affect the ignition timing?
4) If so, how?
5) If not , then what could possibly cause the slightly rougher idle?
6) How, if at all does the tps affect fuel flow?
And please feel free to add any observations you may have and help try to find an absolute answer (if possible) to what the TPS setting should be.
Well I'm going to sleep......But I will continue with my wandering bable in the morning :blah:
