well today i dynoed my car,when the guy was done and i left,my slip light,abs light and vdc off light was on.i called the guy over and he said its normal cause the computer freaks out after they dyno the g's and said the lights would go off in about 10 min.well i drove away in 10 sec later the lights went away..well later tonight...i drove to a friends house and it seemed the car woke the hell up..i really don't get it but its even fast and smoother..in conclusion i was thinking about it a lot of people say after every mod you do,you should reset the ecu..i never did for any of my mods..,do you think the dyno today had something to do with messing with the ecu and resetting it?, i have no doubt in my mind the car is way different from this morning..and way faster

 

ya def. reset everything to program the car with the mods.

 

he didn't really rest it,he was just smashing on the gas on the dyno,and those lights came on..did that reset it?

 

he didn't tune it? and, unless he reset the car (which, he probably did seeing as how you noticed some extra grunt), you have something going on with those mods. or your maf is dirty, or any number of things. who knows. if the lights come back on for no reason, get the code read at autozone or dealership, and see what's going on.

 

Where did you get your dyno done at?..... what were your numbers?

 

my best run was 251.25

 

Ive never heard of reseting the ecu, how do you do that?

 

You disconnect the battery and hold down the brake pedal for a few minutes.

psycraft, Your car was probably in "limp mode" after the dyno. It happens when all those lights turn on.

 

You mean 251??

I'm sure as hell w/ all those mods your car isn't any faster than a stock one, go get her tuned... reflash the ECU (technosquare does a good job), and you will shyt your pants.

 

are you slip, brake, and vdc lights still on? if so...

no none of the lights are still on,they turned off 10 sec after i drove out of the shop,the car just feels way faster.. after everything happened,i went home..then went out later that night,and the car was just amazing..

 

limp mode? can you tell me more about that?

 

yeah i meant 251,i might get my ecu reflashed to get a little more juice..i know the piggy backsysem are expensive though..700+ we'll see..how much more hp can a piggy back system get me..?

 

Dont go the piggy back route, just get a reflash through technosquare... its $500, and you'll have the ECU back in less than a week.

 

so i have to remove mine..and ship it out
