Finally joined VTPS club, calibration numbers, TPS AE
 

Finally wired up the 94 VTPS to my MS3x. I've got an issue and a couple questions.

What kind of numbers are normal for throttle %? I tried messing with the calibration numbers and right now it doesn't go above 7% closed throttle, but if I snap it and let go, the number sits at -50% or so. WOT is at about 170%. I don't know how relevant this is, or if the MS just looks for a low number vs a high number. closed throttle ADC = 670, WOT ADC = 850. I shaved some off the top and added some to the lower number. How important is this really? I searched and found that some people experienced this, but the difference isn't as big as mine.

Also, now that I have a functioning VTPS, does anyone want to share their time based accel enrichment settings? I've had it to 100% MAP 0% TPS (for obvious reasons), and now I don't know what everyone uses/what would be a good idea. I was going to just leave it at 50/50 for now unless someone has better luck with different numbers.

Congrats! normal 0-100% if calibrated properly. For example my air pedal likes adc counts: 72 closed and 846 open.

670 looks very high for closed count.

The problem is my calibration numbers will change drastically depending on if the car is running or off when I do the calibration, and will change just from snapping the throttle a few times to completely different numbers.

How is it wired?

derp

In for any helpful information. Mine's wired up but seems to have a lot of signal noise.

Mine sits around 120 for min and 930 for max.

I suppose you read this: https://www.miataturbo.net/megasquir...aaaaalp-71822/

Oh shit. Going to PM braineack.

Alright, so I'm going to finish this thread so that there isn't 1000 of these threads with no fucking solution at the end. :vash:
Braineack pretty much said what I'm going to say below in some random thread that I never found so it can't hurt if I post it a second time.

These directions:

"For a '94-'97 TPS, assuming you have a pigtail for the new 4-wire TPS, splice the red / black wire of the TPS to the red wire of the car's harness. Splice the green / white wire of the TPS to the green / white wire of the car's harness. Splice the black / blue wire of the TPS to the black / green wire of the car's harness. The red wire of the TPS will be unused."

ARE INCORRECT FOR MS3x. (and probably for a lot of other megasquirts)

The correct way:
Splice black/blue from TPS to black/green of car
Splice Red/black from TPS to green/white of car
Splice green/white from TPS to red of car.

TPS numbers are perfect now.
