Hondata

I am having a problem whenever I tap or press on the throttle the car will choke and die. Originally I thought it was lean mixture which datalog shows but no matter how much fuel I try to compensate with it still has the same results. I tried another TPS and same thing, all wiring checked out with the ecu. Im thinking Im skipping over something but not sure what. Anyhelp would be great before taking it to be tuned.

Log: calibration: Thanks

What is the serial number that is on the s300 inside the ECU?

From Help, About, what is the version of software you are using?

Serial Number: S300-2109
Version: 2.5.2.0

Did you ever figure it out? im having the same issue.

Hi,

I had the same issue with my S300 V1, when I download the tune to my laptop for some reason it comes with less data, also its weight is less than the one the tunner uploaded, if I download the tune from my hondata modify it and upload it, engine will do the same as yours, as soon as you press the throttle it stalls.

The solution I found is to get the tune file directly from the tuner and upload it again, if you don't have it, use a base one from SManager to move your car while you get the file from your tunner.

Hope it helps!

I'm having the same issue as well, I have a stock jdm b16 in eg. I'm a noob, but have been reading my ass off. I go threw have tried several different maps for different motors. I have to add like 10% fuel to overall, crank and start up and have 12% on post start up. With around 10% I can get the car to idle with no check engine lights/ error code the Second I touch the gas it dies. I'm waiting to replace one exhaust stud before I can get it tuned, but I don't want to tow my car to my tuners and have it screwed up and waste both of our time and money.... it's a 94 eg rywire harness jdm b16a stock injectors, stock map sensor and new tps.

What is the error code?

No error codes.

Make sure that you don't have the MAP and TPS plugs swapped.

I have seen this issue very frequently over the past year with s300s. It seems if you download a tune from an older version software with a newer one and then re-upload you have this issue. This was never a problem in the past. It would be nice to be able to download the calibrations without worrying about this.

I had the exact same problem and as everyone else, and got the exact same fix as well. I spoke with the tuner and reuploading the original map did the trick. What is weird is that I tried running a stock map and copying the tables. This should have solved the problem in that I was running a base map. However it didn't do the trick. I wouldn't hold my word as bond as I am still new to hondata but it should have worked.
