I am beginning to think my board is defective.. THis never happened w/ my s200..

I"m going to have to find someone who has a s300 board and test it against mine..

okay..

I now have my 02 and wideband hooked up on my DP.. on hot starts, it stills runs lean, around 18-19.. for the IAT corr, I had to add about 10% fuel @ 159 degrees, to help bring the AFR's down..

btw, i snipped the analog 1 signal from my LM1 to the ECU harness so it doesn't affect the 02 ...

as the title states..

How do you do this? it is grayed out in the menu when you run the program..

thanks.

i have stock GSR cams and am running in F degrees..

My LM1 wideband is permenantly hooked up and the Analog1 output goes to d14, while analog2 goes to d12.. the analog ground is spliced into the ECu ground wire as well..

WHen hot starting the car, the engine doesn't go lean until the wideband ...

gigi,

did you ever figure this problem out??

I had this exact same problem w/ a chipped p06 that I used for s300.. It worked fine for a couple weeks w/ no problems, but began to throw this code every now and then and eventually most of the time..

Sometimes it would result in the enigne stalling and was more of a nusiance.. I finally got tired ...

just got back from the track using the gm boost solenoid and boost control

I have a 44mm WG w/ a 11 psi spring, gt35r, ramhorn mani and closed dump tube..
set the duty cycle fixed at 25 % and activation @ 10 psi.
Boost cut set @ 19 psi..
The solenoid input is tee'd off from the manifold line going ...

Here's mine I just logged again.. LMK what you get out of it..

thanks..

I moved my IAT sensor from the IM to my charge piping, IT helped a little, but the problem still persisted..

Its more noticable when the weather is warm.. right now its like 30 degrees here, so i"ll have to try it again when it gets around 60 or so..

i'm in the same boat too.. I bet its a glitch in the software or something.. Never happened on my s200 and if its happening to 2 or more people i'm suspecting it isn't an isolated incident..

I tried playing w/ the cranknig fuel trim too w/ no sucess..

I didn't change anything on the ecu harness, ie move the wiring around.. The only thing i swapped out was the ECU's.. Unless the p06 and p28 have different pinouts for the sensors..

I"ll have to get a ecm diagram for a p28.. I also noticed that my 02 voltage stays around 3.85V..

Nonetheless, I ...

Okay,

Here's my new problem.. I just switched to a p28 ecu for my s300..

I was using a chipped po6 before and had no problems switching from open loop to closed loop. I am using an Innovative LM1 and have the analog signal hooked up to the ecu inputs for the o2 sensor. and also to the EGR valve ...

i will look over the ECT values..

Also..

I"m experiencing another very odd event..

I recentl switched from a chipped p06 to a chipped p28 for my s300 and when I run closed loop with the p28, the engine goes real lean.. I actually have to run it in open loop to get it to idle and read normal AFR's ...

nope..

GENUINE RC 750 Injectors..

I never had this problem when i was running s200

I'd like to know too.. My car runs real lean for about a minute and has also died out sometimes when I start the eninge after its been off for 10-30 minutes.. my WB shows AFR's in the neighborhood of 17-19..

In the morning when I go start it up, the AFR's are fine and this problem is non existant ...
