Hondata

help ive just installed my first hondata s300 on a rebuilt ecu p28 and i can connect to it all the things on the s300 tab in the manager are check marked. but when i click on the tps tab it wont let me calibrate it then i started the car and realized that no sensors or gauges are reading (edit just realized the hondata chip is flashing red)

Here’s some of the solder joints
I don’t have a picture but I did install the jumper (black striped) in j1 and the resistor in r54 right below it
Ecu was converted from auto to manual if that matters

Just checking, but you are starting datalogging (lightning-bolt button near top of main window, F10 on keyboard) when trying to view the sensors and calibrate the TPS, right?

Bye, Arno.

Uh…. Let’s say no. So I have to click f10 and then try. Why is the hondata flashing red though.
Also I had this problem before with the old ecu but it seems like the engine revs down and almost would stall it would stall sometimes. Is there a way I could fix that with the ecu

Am I supposed to start it or would it start automatically

I just checked and now I have the ability to actually click the tps read buttons. But minimum is alway -5 and maximum is always 60 no matter if Ik pressing the pedal or not. And tps display on the display tab doesn’t change from -13 while I’m moving the pedal around
Also says my ect is 302f and my iat is the same 302f
When the car is cold

Post pictures of the completed soldering on the bottom of the ECU.

Is J12 cut on the ECU?

Uh I forgot to cut j12… sorry it’s my first time. It works now. Thanks for your help and advice
