I worked on enrichments a bit more for for some reason had to do some serious tuning in the upper kpa range. I will do more later since I'm still working from home on my real job.
Is there any reason I can't bolt on a 99 throttle body onto this 1994 plenum, change the settings, and have IAC again? I'm also going to run to homo-depot and get some PVC pipe to "delete MAF" later today.

Well, I have a 99 T-body for the 1995 car but there are problems.
- The 1994 TPS is a 4-wire, 1999 is a 3 wire
- It appears the sensors will not swap over (please clarify if possible)
- 99 IAC connector is different from the 1994
- I have a 2001 harness but none of the sensor connectors seem to fit.

Let's educate Hustler on how to rear a wire diagram and ultimately learn to think for himself...which is going to take work. I don't really know how to read a wire diagram.
I have a 1994 TPS:
I have a 1999 TPS:
How do I know which wires go where based upon wire color or the cool squiggly lines.
I'm guessing that the 1999 red/blk is the ground.
I'm guessing that the 1999 grn/blk is signal.
I'm guessing that the 1999 lt grn/red is power.
I don't know what the hell is going on with the 1994.
Thanks for the help, bros.

The 99 and 01 use the same connectors for the TPS and IAC. So your 01 harness should have these.
The IAC will certainly not swap over from a 99 to a 94. I'm pretty sure about the TPS as well, but can't remember right now.

Then maybe "The Parts Group" sold me something else because that harness has no connectors that fit on my 99 throttle body. There are some which are close, but they have grooves in the wrong places. I tried every connector, they don't fit.

Edit:
None of them fit the IAC nor the TPS.

Okay, I found the problem. I cut off the TPS and IAC pig-tails from my spare harness over the summer when I recieved it, then put them in a safe place so I would not find them the next time I went looking.

I'm pulling my hair out over enrichments and I don't understand why they keep triggering when I hold full-throttle. Here is my stuff, specifically look at 20978-20980s in the log.

I don't get it, this was easy as ---- on my turbo car and on all the NA cars I've tuned, for some reason my brain is not working this time or I'm most likely making a stupid mcsteak.

Please also not that at the very beginning of the log I have an RPM dip just after TP goes +20%. I'm not sure how to get rid of that, but I'm thinking MAP enrichment like on my turbo car.
Here are some other things I guess I don't really understand.
MAP Enrich (my friend)
Here are some other things I guess I don't really understand.
MAP Enrich (my friend)
- Mapdot threshold - the amound of MAP change required to initiate enrichment
- Accel time - how long you want the full MAPdot enrichment to last
- Taper time - how long to taper down to 0% enrichment after the Accel time period
- end PW - I don't understand what this does if I'm already telling it when to taper to 0% in Taper time
- TPSdot threshold - the minim % TP change to initiate enrichment
- Why is there no taper? How do you guys run 100% TP and get a good enrichment tune?
- In MLV, does TPSdot tell me how much PW its adding or something else?

annnnnnnnnnnnnnnnnnnd now its perfect, lol.
I was getting a weird oscillation at idle which I attached too. I'm guessing heat soak on the IAT since it was ~200*f IAT.
Can someone go to 252.896 in "oscillation" and tell me what's going in? The car is idling, then suddenly it starts squirting more fuel without enrichments triggering or any throttle application.
weird

The car is much much much better, I'm very happy with it today. I still have a question though. I've managed to dial-out the initial lean-ness on tip-in, but then its still going too fat for about .1s after tip in. You can see this at 3960.729 in this log. I'm not sure how to trim that all the way out when leaving from a stop.
I've never had enrichments and throttle response this good, I'd say its near ITB status when moving, I can't touch ITB free-revving.

I could not get TPSdot working on free rev. Any thoughts? This might be a scenario where there are two schools of thought that get the job done...I hope because I don't care to chase this down anymore.
How does my log look? Can it get better? My turbo car is not like this at all. I set it and forget it and the car drives great.
