i'm pretty sure my current one is out. the check engine light is always on and the self diagnostic says that's what it is. don't know if i should get a stock honda one or some other brand. i don't want an ultra expensive one, just better than stock if not too much more than that. any suggestions?

also, the ecu runs in a set mode if the O2 sensor is out correct? i tested my car with a g-tech and only got a reading of 120 hp when i should now be getting btw 132-140. i was at 132 last time and since have gotten several upgrades. would a bad O2 sensor effect performance that much?

 

have u tried checking your o2 with a multimeter? i think mine is giong too cuz i keep getting cel on it. but those o2's are sure more expensive than what i had i mind . but how is that g-tech meter working for u? i got one too and its just a pain having to enter the weight but its fun to play with. anyway, try running a check on your o2 .

 

didn't think of that. i'll have to check it tomorrow. but somehow my performance is off ~20 hp. i have a hard time with the weights too on the g-tech. but using it i've found how sucky of a driver i am. need to work on launching. pretty good though for a $100 dyno.

 

u were able to pick one up for $100? good deal
