So I'm still having weird issues, and I can't really figure out what is wrong, or what I am doing wrong.

I've tried adjusting the fuel table in both closed loop and open loop. I've watched a few tutorials, the thing shows how much estimated fuel change it needs, I adjust it. It will say some wild ...

No, that's not intentional, well, I mean it sort of was? I was trying to match the original fan switch temp, and I saw that was the default set in smanager and figured that was probably good because the number didn't turn red until 200 c lol. What do you recommend I use?

And I was fretting about ...

The idle is fairly consistent. It will stay for the most part between 830-870. Occasionally it dips a bit more, or raises a bit more. Now here my inexperience comes in, but I noticed the timing would change in time with the rev drops, and the afr changing. The AFR is a lot more inconsistent than I ...

I actually just found the tutorial on that in the instructions and that is going to be the next thing I do, along with double check for vacuum leaks. Then I'm going to verify my base timing again, but I'm pretty sure it's right. Thanks for the help! At least now I know I'm looking at the right things.

Reporting back, my initial problems were indeed fuel pump related. My brand new AEM pump was bad right out of the box, I guess, but not bad enough to completely lock up, just bad enough to barely send enough fuel to start the car. I had a hard time troubleshooting this one because the pump kept ...

Additional info: The more I look at it and mess with it, the more it does seem like it's all related to some sort of fuel pressure drop issue. Not sure if its the pump itself, or what. It's an AEM fuel pump, 320 lph I think. I also have larger wiring running to the pump, not factory wire. It ...

If you go to the s300 button at the top of the screen, then click on the calibration storage tab, do you have the box checked to automatically store calibration after uploading to the s300?


If I need to set that manually, then I do not. I will check this option.



I did check this morning ...

It's probably a driver issue. I also can't connect to mine via just usb, and when I try to install usb drivers I always get an error.

if you're getting a password prompt when connecting via bluetooth, try the default pin. 0000. it might take a few tries because windows is really bad at pairing to these sometimes.

Just got my s300 running with no errors or anything, with a new fuel system (rail, injectors, regulator, pump, filter). I also have added an AEM wideband gauge, wide band o2.

I have a couple of issues that I'm having. I think with the ECU and software maybe, but also my tune itself. The car ...

I feel so stupid, so stupid I almost don't want to post a reply. But I will. I read the Honda wiring diagrams wrong. I read my electrical manual wrong. I made assumptions that I shouldn't have, with the issue staring me in the face the whole time.

I never plugged the damn sensor in.

Technically ...

Yeah, I thought the same thing. That's why I got a second s300 and it gives the exact same issue, down to the exact same coolant temperature reading when the engine is off. One s300 I tried in two different ECUs, the other s300 I just got last week already installed into a p28 and it gives the exact ...

so I tested it in another car AND bought a new working s300.

Been tested in another car. Been tested on an engine simulator. Also have two more ECUs now that all do the same thing. Only get a code 6 on this specific car.

Hey guys, I hope this is the right place to post this question. I will try to summarize what I've done as best as possible.

I have a 93 and a 91 Accord Wagon. In the 93 Accord, it was my original car, with an H23A swap that I could never get running perfectly. It had some issues with water getting ...
