Couple questions about 2.0 on 91 NA
 

First question I have is about the TPS on a Series 5. I have my tps tester lights hooked up and they don't seem to be coming on, so my question is what does YOUR rtek read on both narrow band and wideband when your TPS is properly tuned?
Second question is what kind of AFRs should I see at idel, crusing, and full throttle? I do have a wideband to monitor AFRs.
This is a 91 Non turbo with a large streetport. Ported and modified TB as well if that is relevant.

I am also aware that my TPS may be bad and I have a WTB ad up.

Thanks,
Robert.

I have my narrow range set to 10% at closed throttle, and wide set to 20% at closed throttle, However as soon as I give it more throttle, the wide drops to 0% and goes up from there with the throttle as well as the narrow. Seems to be doing well so far. Engine only has 30 miles on it now.

i'll let you know what mine looks like after i buy a new cable :(

Hah! I had to do the same thing. The one that came with my Palm was shot.

If it goes to zero, when you start moving it then it's not right. Set the wide to the "second" 20% It should go from 20% and up, never back down. If the TPS is out of range the ECU defaults the TPS to a specific value, so what is happening is it's defaulted, then if goes into a valid range and starts at zero. But at idle, it should be 20%.

I had another tps on and it was set to 20% I figured this would be safe as the I do beleive the ECU is defaulted as you said and it defaults to 20%.

So, if I have the wide set to 20%, where should the narrow be? Right now it is at about 10% at idle.

Thanks for the input. :icon_tup:

Anyone else have input on this?
20 and 10% seems to be about right.
Just want to make sure if I can confirm with someone who has S5 RTEK and TPS tester lights.

they should both be 20
