So after doing quite a bit of searching I wanna make sure I'm doing this correctly. Shortly after I got my 97 Accord N/A H22 tuned with Hondata S300 my TPS sensor came loose and my car would stall out when I came to a stop. Now I'm trying to re-calibrate it to match the rest of the specs so it runs correctly. A while back I got the TPS back to near stock with probes and a multimeter but it was still running a little off. I take it that all I have to do is start datalogging and set the min/max values using the gas pedal then save the setting and re-upload the new file? Am I missing anything? I'm fairly new to S300 and the only change I made to my tune was adding launch control and that was fairly easy. This is my DD so any tips would be greatly appreciated. Thanks for your help.

 

Yes that is all you need to do, but you should adjust it as close to a 0% correction as possible when closed.

 

So you think I should go back and re-calibrate it manually with the multimeter just to make sure it's as close to oem spec as possible? I've read that some ppl say the Hondata system will take care of it no matter where the values are currently at but that didn't seem right to me. Thanks for your help.

 

Hondata will compensate ALMOST no matter what, so the person who told you that is mostly correct lol.
but you should still calibrate the sensor as close as possible to stock spec of 0.45v at closed throttle. and of course recalibrate the settings in hondata after.

 

Shitty part is the fact that my IACV is mounted right beside my TPS bc I got a euro-r manifold. The coolant lines block the screws and need removed before I can adjust. I also have to remove my intake to get to the wiring. But it will be done. I will report back with any issues I run into. Thank you all for your help.

 

So I got the TPS as close to spec as possible and then made the changes in Hondata and uploaded the new file. The idle jumped up and down a bit for the first 10 minutes but then the car stalled out and now it won't stay running unless I keep my foot on the pedal. Only thing I can think to do is tighten the throttle cable a bit to keep it running. Any other ideas? Here's a pic of my TPS readings. Do they seem normal?

 

yes those readings seem very good actually.

try this:
-make sure you have the newest version of smanager software. reboot after install if it updates.
-unplug the ecu from the laptop. open your map. manually type in these: min: -1.0%, max: 100%. save the file, close smanager.
-turn ignition on, plug in to laptop, open smanager, open the file you just saved, upload the map, close smanager, turn ignition off, disconnect cable.
-turn ignition on, wait for fuel pump to prime, push the gas pedal to the floor then let off, then turn ignition off for at least 15 seconds, and close smanager again.
-ignition on, connect cable, open smanager, do it the proper way this time reading minimum and maximum, save, upload, turn ignition off for at least 15 seconds.
-start the car but do not touch the gas pedal. let it fully warm up at idle, never touching the gas pedal. after it has warmed up, try blipping it in neutral, and try driving.

if it struggles to idle, you probably need to adjust the idle screw if your TB has one, or adjust the distributor and/or base timing in the map, or make a change to the idle valve settings in smanager

 

My plugs haven't been changed in almost a year. Could this be an issue? Can I ask what this method is trying to accomplish? I'm just asking bc this is all new to me. Just so you know, I definitely have the latest software. I checked before I did all this. I do not have an idle screw bc my throttle body is from an S2000 I believe. Thank you for your advice. I'll see what I can do.

 

plugs dont usually cause an idle issue, but I suppose anything is possible. it would be worth it to check the plugs, and maybe replace them, and make sure they are gapped correctly and torqued properly.

through all the different versions of the software that has come out over the course of years and years, I've seen some of the most awkward bugs and glitches. following what I posted really has no explanation lol, its basically just forcing some different data through the unit to do a "soft reset" of sorts. its possible the map had a glitch that passed on to the ecu, I've seen it before. uploading a few different data points for the same data usually solves it.

 

I will try it and see what I get. Thank you very much for your advice. It goes a long way when you're new at something.

 

sure, you're welcome
