Loss in acceleration + throttle response ??

spearfish25

FWIW, when I started adding Techron to my tank, my fuel gauge started reading crazy. It took about 5 tanks to get the gauge working right again. Maybe unrelated, but that stuff isn't going in my tank again.

Very interesting. I never had that issue.

I noticed the exact same thing when going from shell to techron, never again

I've been dealing with this situation ever since I purchased my Z back in June of this year. My car is bone stock and has had one oil change so far but I noticed the delayed throttle response/loss of acceleration about a week after I got it and has continued to do it up until now. It typically does this when the car is warmed up (oil temp 230-240), but I'm really surprised no one has determined the cause of this yet! I'm taking the Z into Nissan tomorrow to have them investigate this problem so hopefully I can get some sort of answer..

So far I believe it is already known that the ECU starts holding back power when the oil temps go beyond 200F. I just hate it when the car ramps up slowly in 1st every once in awhile regardless of oil temps.

Ahhh alright, I must have missed that. I thought I read the entire thread lol. So would you say an oil cooler is a necessity if I live in Phoenix, Arizona? I can't take it when my car starts to do that, which is almost every day. My average oil temps are 220-230F

Definitely take it in. They likely wont' do anything (ECU reflash if you're LUCKY, but that probably won't fix it). But they need to know about it. If this ever gets resolved, I'll buy another one =)

I'm gonna do my best to make sure everyone that needs to know at Nissan hears what I have to say. It's unfair that I have to deal with an ECU that puts my car in limp mode purely from daily driving. Hopefully when this is all said and done... OIL COOLERS FOR EVERYONE!

Guys I installed the Black Bettys grounding kit on my 370z today. This kit blows away the Stillen. The kit has TB ground wires, after install I went out to drive around and kicked it up pretty good and I know have a much better throttle response then before.

Now I only have 780miles so far, but I did have lack of throttle response right off the dealer lot with only 22miles on her.

I would check this out:: Go to myg37.com so a search for Black Betty's custom grounding kits:

I also run Shell Gas 93.. Seems like grounding out the TB helped big time :-)

I think the verdict on grounding kits is still up in the air. Unless your car wasnt being provided and good path for the electricity I dont see how a better grounding kit will help. Now if you have added things like alot of stereo and things of that nature then it might help but I think stock the stock kit should be good. Are you sure it isnt just a preceived gain?

Well, you have look at the stock G-wires. They don't ground out the TB like this kit does. I installed this kit for looks really, I did not really think to get anything out of it, but it did help with throttle respones.

well Im all for better throttle response, might have to do that one one day.
