How-to: Scale your TPS in Hondata Kpro/Kmanager

Everyone with Kpro should do this, even if its stock. This has to be done everytime you load a new BASEMAP. If you're using someone else's tuned map, that is still considered a basemap for you, as the map isn't tuned to your SPECIFIC car, even if you have same bolt ons, engine, turbo, head, carpet....it doesn't matter, every tune is different.

Scaling the TPS tells the ECU where your pedal is fully up (tb closed) and fully down (wide open throttle aka WOT) and where it is anywhere between those points.

Here we go:
1. Remove all mats from under your pedals. You should only have either the OEM mat with hooks, or bare carpet. If you have weathertechs or something, you need too trim them so they don't get stuck behind your pedals. That makes things rough on the clutch and transmission when you can't disengage the clutch all the way. Too many people drive like this unfortunately. This also lets you press the gas pedal all the way down.

2. Connect your laptop to the kpro ecu.
3. Turn the key to the ON (II) position. DO NOT TURN THE CAR ON WHERE THE ENGINE IS RUNNING.
4. Click on the lightning bolt in Kmanager.
5. Open the Parameters window. Circled in red below.

7. Scoll down.
8. Click the TOP [READ] button. (above picture in blue)
9. Press and hold gas pedal all the way down.
10. Click the BOTTOM [READ] button. (above picture in blue)
11. Go to FILE > SAVE AS... and save your calibration as a new file.
12. Click the UPLOAD button to upload the newly calibrated TPS file to your ECU.

Omg this saved my life! I kept getting an error code p1122 for tps voltage higher than normal. Once I calibrated it correctly its all my check engine codes went away and the car was a lot more responsive.

Damn good info to post up.

In my case im using an Accord TPS as it was the only one available at the time, but i have to choose either good idle or WOT (even with the pedal stops removed). I cant have both. So neutral is 0 and WOT is 96%. This time around ill get the proper TPS.

Can i add just one thing?... i noticed that i had to keep clicking on the read button to get a reading as to where the tps was showing. If you follow the same process but instead of going to the parameters tab and going into the tps tab, you go to the sensors tab and you can see in real time how the tps responds when you push the pedal. once i got it to 0% i went into the parameters tab and made sue that the tps was showing a true 0%.

great info!

KPRO always amazes me!

you can do that IF you're adjusting your TPS, which you shouldn't unless you have a HR or something aftermarket. as far as stock TPS goes leave it the hell alone, unless of course you broke yours and replaced it, be really really careful. That is good info tho I wasn't thinking about the aftermarket people. If your TPS is close to what it should be, then scaling it via this how-to will still tell the ECU that where you read 0 is closed and 100 is WOT, as far as datalogging goes.
