That depends on what calibration you have loaded and what your setup is. It is entirely possible. Time to get it professionally tuned.

Thanks Dax, looks like that’s the plan now.

Ok. Is having to add that much fuel in open loop to get it to idle a normal thing?

So I tried changing the idle in closed loop and it worked fine. When I changed to open loop it leans right out(well out of range) I had to add 20% to the fuel map 3 times in order for the a/f to come back to normal. Light still flashing red. Why do I have the flashing red light?

I have swapped the s300 board into a new ecu. The only issue this fixed is I can now hook up my wideband to d10. With the old ecu the eld sensor was always reading voltage even with it completely disconnected, now it seems to be reading fine connected to the wideband and reads 0 when disconnected ...

I’ll try another ecu again and see what happens. The wiring for the wideband is definitely correct.

Thanks for your help

Version is 2.7.5.0

Yes i have been uploading calibrations.

I've attached current calobration and datalog as well.
I can't datalog a/f because if i connect my wideband to D10 the enigine stalls and if i connect to d14 it runs really rough and sometimes stalls

When my tuner tested my ecu A17 was just one of the outputs that was staying energized. When I put my ecu back in my car I disconnected a17 like you said and still nothing has changed. Engine still runs very rough and the red light still flashes when I have it connected to my laptop and SManager is ...

P06 (converted for VTEC) and P28

Version 2.7.5.0

We’ve disconnected A17 but still the same issues. My tuner/installer has put the S300 into other known good ECUs and still getting the same results

My tuner checked with the on-board datalogging and it’s still the same. Could it be anything else or is it the s300 board itself?

Serial # 48056

He said that’s one of the outputs that stays energized amongst a couple others. I’ll try to get more exact details when I speak with him

Thanks for the reply. My ecu is a P06 that was previously converted for VTEC. I’m not sure which ecu my tuner used to test the second time. He still has my ecu and will let him know to disable on board datalogging and see if that makes a difference
