Throttle Position Sensor = How much gas you're giving it. 80% is the max value you'll receive, so don't worry there isn't an additional 20% missing.

"Throttle Position Sensor actual." It represents what position the throttle blade is at. 0% is closed and roughly 80% is WOT.

"TPS requested" or "accel pedal pos" shows what the DME is asking for the throttle to be. 0% is closed and 99% is requesting WOT.

It might drop for a lot of reasons... if yo uhave traction control on for instance and you lose traction (even minimal loss) you'll have throttle closures...
If I'm not mistaken, one of the ways the DME controls boost is by adjusting the throttle blade.

First, you have to determine which ECU you have. I did this by plugging my Cobb AP into the car and click on "Install." It will show you your ECU type. Then unplug the Cobb AP, go to your computer, and download those maps for your ECU.

Here's what you need to do:
  1. You need to pair your AP to your car; once you do this you'll know which maps your car uses (IJEOS, IKBOS, I88OS, etc).
  2. Get in your car, close the doors & turn the power on (full electric, so the needles tell you how much gas, etc -- don't turn the engine on)
  3. Plug your AP into the car using the OBD port & select the "Install" option
  4. Once you start the install, a "Vehicle Information" screen will come up that tells you specifically which maps correspond to your car (ex: I use IJEOS) -- Remember whatever comes up.
  5. Continue your install, a little gear & loading menu is going to come up. This is going to take ~25 mins. This is cause its your 1st time & the AP is backing up your factory DME settings. This way, if you ever need to switch the car back to stock (for service, selling your AP), the settings are saved on your AP. DO NOT OPEN THE DOORS AT ANY POINT!
  6. Once it completes, turn the car off to complete the install.
  7. If you get internet in your car or when you finish the install, go to the COBB website & download whatever maps you want to use.
  8. You have DPs, so you should run Stage 2 -- I recommend that you upgrade your intake if you can (aFe DCI, BMS DCI, even a drop-in). If you have access to 93 octane, you can use aggressive tune. If you only can get 91, you have to use Sport.
  9. Download the maps onto your computer & sync your AP to get the maps on it.
  10. Go back to your car, and go thru the same process -- Get in your car, plug in the AP, run the electric & select the Tune option. There will be an option "Change Maps"; select whatever map you want, wait for the install to complete & enjoy

PM me if you have any questions/problems when you go to install. BTW, the reason why you can't open the doors when you're doing the install is because the DME will want to trigger the door gong. Because you're trying to flash the DME & its trying to do something its programmed to do, it'll crash the DME & your car will need to get towed

The AP will go into recovery mode and save the DME, no need for a tow truck.

Hmmm I just saw this post, It does seem to happen when I reach 19psi while spiking. It also only happens during 3rd gear pulls from 2-2500k, maybe the drop is the cars way of adjusting like you said. Also this was happening on the v301 maps. I did do some live logging on the v401 keeping an eye out for the TPS % it happened but only for a brief moment. I will log it officially this weekend. Thanks for the insight.

I wonder if the tc intervenes even if the light doesn't flash. I saw this with tc only, but since getting lsd don't see that.

This is interesting. It was my understanding that the e-diff does not turn off when you turn off DSC/DTC. So maybe you are onto something, like there is some level of tc that never goes off to work with e-diff.

edit: ...that also does not trigger the light...

Interesting, if this is tru ill do a first and second gear long real quick to see if its traction related. Also I turn my dtc completely off any time I rip it.

From what I can tell it looks ok but there's alot going on in your graph. Take some logs in 3rd gear 2-6k rpms and repost. What are your mods and what map are you running?
