Default Couple of minor things

First off, I finally got my MS installed in parallel on my 97. I put switches on both spark and fuel control a la Kingof1337 (but external of the stock ECU). I haven't actually let MS take over controlling the car right now, right now it's just "viewing" whats going on with the stock ECU.

Anyways, I tried to calibrate my TPS, and even though I have it calibrated correctly, according to the TPS % gauge, its always at 11% when the throttle is closed and 73% at WOT. I'm not sure if this is normal or not.

Also, just for temporary use, I have the stock NB O2 sensor being shared between MS and the stock ECU. It fluctuates wildly randomly it seems, is this normal?

Other than that, I guess everything is normal. I have yet to set the timing on the car yet, will do that tonight.

on the TPS check your connections, and the NB sounds normal but i am unsure. glad you have it all on cue though go ahead and give her a try you might be surprised. the tps might also be a calibration issue i would go over how you calibrated it before maybe you missed something.

You need to calibrate the tps in both megatune and megalog viewer. You need to know ADC throttle closed and ADC throttle open. You can change one of your gauges to show throttle adc. There is also an aquire current position function in the tps calibration screen. Very easy, takes only a minute to do in each program.

Mine is something like 17ADC (0%) closed 205ADC (100%) full open.

I'll give that a go Ben. For reference, from what I measured, closed mine is 29ADC and 189 full open, wonder why mine is so much different than yours.....
