I logged my data during my 1/4mi runs on my auto g35,,
what i found interesting is that my absolute throttle position was never above 82% and load is around 89% on those runs. Is this normal or not?
I have all the data in Excel file if anyone is interested in digging a little deeper, i got 02 sensors, short and long trim, timing and much more info there that could be of help to somone who knows what they are looking for.

Take your floor matt out...LOL

 

What engine management are you running? You might have the calibrate the throttle min/max voltage, at least you do on the UTEC. But I didn't have to change the stock settings.

 

I have no engine management just OBD2 diagnostics with a laptop ,

 

Take you floor mat out....lol

Seriously, i had a customer who put in these new floor mats, and came back saying his car felt slow..Well the floor mat was causing us to only see 80% TPS..
Otherwise it is a throttle issue.

 

Please tell me you did not sit there and type all of this information...

 

ever heard of copy and paste?

 

umm,,,,it would have to be a thick *** floor mat

 

What r u using to log?
