URGENT -April 30th Need help- R137?

[Jee]

I accidentally cut R137 mistaking it for R138. I attempted to solder it once I realized my mistake but once I plugged it back into my car it wouldn't stay running. I kept giving it throttle until it would idle but my AFR gauge reads 22 at idle now.

Could a blown R137 resistor really cause this issue or did something else go wrong here?

Car ran fine an hour ago until I attempted to get wideband working


it runs full lean on the gauge, i changed the fuel trim to 40% to get it to idle at about 16:1

R137 relates to the ELD input as well. Are you running closed loop from D10?

That's not good..

I'm still running open loop with closed loop disabled. The car isn't driveable and I've got a non-refundable track event tomorrow so stress levels are high, forgive me if I'm missing some info but I will go over it again.

I drove the car all day, got home and took the ECU out to cut R136 and R138 (which wasn't there to begin with) and ended up cutting R137

After I realized I did that i attempted to solder the leg back with a cheapo butane soldering iron. I then checked resistance with my multimeter to see if the solder joint worked, the first time I tried my multimeter started reading and auto adjusting and I was just looking to see continuity so I called it good.

I then removed D10 pin from my ECU harness and added another pin to the yellow wire of my innovate controller.

When I started the car it would just die, its running super lean for some reason.

I then put the original pin back into D10 and it didn't change.

When I check resistance/continuity again I couldn't get any readings.

On another note even after scaling with LM programmer I cannot get sManager to read proper AFRs in neither D10 or D14

It is possible that you have damaged the ECU. If it is in open loop then the ELD input should not matter.

I have tried another s300 v1 ecu and it works with my tune file so the ecu has died. I have another ECU being chipped for me but I still cannot get the wideband input working.

So for anyone else that might do the same ... don't lol

I have scaled the lc1 with lm programmer and have selected the correct input in Parameters>Closed Loop Advanced and set the Voltage/Lambda Conversion Table to mimic the LM programmer settings but the AFR stays at 7. I tried D10 and D14 inputs. Am I missing something?

Post your calibration as well as datalogs showing the issue.

[Jee]

I gotta be doing something wrong if all the inputs give me false results. Take a look, thanks

Have you made sure that the ECU has the components needed for D12 to work: http://www.hondata.com/help/smanager/an ... ghtsub=d12

No, I didn't add a capacitor, I tried ELD with R136 and R138 removed with the same settings other than the input, I also tried D14 with no hardware changes. D12 as seen in the rom was just to test the input as is. Lets presume I'll go with D14 for ease of use

[Spunkster]

I would recommend against using d14 as it cannot see the full voltage range. You should be able to use any of the other 3 inputs as long as the correct components have been added or removed.

Let's go with the ELD circuit, once I remove R136 (&R138 if present) does the rest of the cal look good? Is there anything else I need to adjust?

[Spunkster]

You will have to see how it works with the settings you have.
