There was a kid with a red G35 auto. It was his first time there. He only had 1000 miles on it.. He was running 14.9 all night.. Think he had like ummm 5 runs and hit 14.9 every time!!! I asked if he reset his ECU and he said no.. So I went to his car and did it for him and guess what??????? He ran a 14.6.. So for all the people that think its physc or not true here is realy good showing on how the car kinda drags after a while and that a reset of the ECU wakes up and brings our cars back to life!!!

How do you reset the ECU? Thanks

Dknibb =Emerald mist sedan/auto/2003/sport pkg/aero/

 

turn the key to on DONT start the car!!!
wait 3 seconds
then press the gas 5 times in 5 seconds
wait 7 seconds
then press and hold the gas for 10 - 12 seconds
you will see the "check engine" light blink if it doesnt restart the process
after it starts to blink take your foot off the gas and wait like 2 seconds (not critical)
then hold the gas down for another 10 seconds in order to flash it..
Then turn your car OFF
Now you can restart your car normally and enjoy your lost power!!!

I had my ecu reset by the dealer on tuesday so maybe thats why I had better times yesterday. Truthfully though I couldnt tell the difference.

 

I personally think its the way you guys launch.
You guys saw what my car did and I never reset the ECU

 

What are you talking about?!?!?!?!? I have nothing to do with this.. I know what my problem is 60' and too much spinning when shifting into second.. Plus i would LOVE to have that 100LBS driver diffrence by letting my GF run AND do better then me.....

This was to show people an experiance.. A test if you will.. Lots of people want to know if reseting the ECU does anything and i thought this was realy good showing.. It doesnt take a rocket scientist to figure out how to launch with an auto.. So personally i think your an Idiot for saying that..

Sorry if I sound like a D**k but when someone pretty much tells me that I dont know what the hell im doing I take it personal.. Im done hopefuly we can get back to the topic and make this a good one with lots of imput..

Hey, its me with the red G. Your right, after the reset, I got a 14.6. Btw, for all you guys, the car weighted 3670lbs because I was a fool and filled up on gas and left loads of stuff in the trunk. I could have probably saved at least 200 lbs worth of stuff. My first 5 runs, were all 14.8-14.9. The last one, after the reset was 14.6 with 94mph. I had run a higher mph before using the manual mode but i hit the rev limiter once. My highest mph then was 96.5. I think I could probably get the car into the 14.4 area if i took out all the stuff in the trunk and didnt fill up on gas. I'll have to see next time.

 

First of all the problem with launching was directed towards the guys with the automatics. I understand its harder to launch a car with stick, but I'm sayin that reseting the ECU has nothing to do with the better times. There is NO WAY that reseting the ECU made that guy 3 tenths of a second faster. Plus with only a 1,000 miles on the car and it being totally stock, you shouldnt have to reset the ECU.
I didnt mean to offend the guys with the automatics, cause I know it was their first or second time running the car. All they need to do is work on there launch. There is nothing wrong with that.

 

Hold on a second...

If the car ran 96.5 mph before the reset and only 94 after, then it actually lost power. Horsepower is best determined by trap speed, not ET. ET improvements are more reflective of a better launch and shifting. I would be interested to know what the 60 ft. times were for both the 96.5 and 94 mph passes.

FYI - I'm simply stating my observation, not my belief one way or the other on the benefits or lack thereof of resetting the ECU.

Did you see the post b4 yours.. Personally when I reset my ECU it feels a lil more peppie if you will.. I dont expect it to do wonders but i feel that reseting it keeps you at your best at all times.. I belong to other forums with have a lot more info then this one has to offer.. Techno has said that the ECU will adjust itself.. And with a computer that smart your telling me that it cant be wrong or get confused??

Thats like saying that Windows 98 NEVER crashes!!!

I agree! you are totally correct juice.

 

the 60' times are: for the 14.6 run---- 2.243. For the run with a 96mph trap speed--- 2.429. If you guys want, i can post all 6 of my slips up tomorrow.

 

Yep. First try. We'll see if it restores anything. I drive like a mad man anyway so it may not change much. Thx for the instructions/how to.

 

That's all the info I needed.

You had more wheelspin with the 96.5 mph trap speed pass (2.42 sixty) versus the 94 mph trap speed pass (2.24 sixty), which is how it should work. Your improvement in 60 ft. time appears to be the reason your ET improved. More wheelspin at launch equates to higher trap speeds with higher ETs.

Early pass
2.42 sixty; 14.9 ET; 96 mph
(more spin= high ET, high trap)
Last pass
2.24 sixty; 14.6 ET; 94 mph
(less spin= low ET, low trap)

Regarding your 60' times....

If you ran a 14.6 with a 2.2 short time and had a trap speed of 94 MPH

And you also ran a 14.8 (or 14.9) with a 2.4 short time and a trap speed of 96 MPH

Then it seems fairly obvious to me that you hooked up better on your 14.6 run (as evident by your quicker short times) as compared to your 14.8 and 14.9 runs. Also, keep in mind that spinning the tires on launch will usually give you a slower ET, but a slightly higher trap speed. Why? Simple- when you spin at the start, you end up with a higher rpm at the finish line than you would have otherwise had. And the higher rpm equals a higher trap speed, obviously.

I think the 14.6 time was more due to better driving than reseting the ECU.

Also, you said the 14.6 run was after a bunch of other runs too, right? Did the temperature drop? I know when I go to the track in the fall, my best runs are usually towards the end of the day when the temperature drops.
