Why is it healthy for the car to reset the ECU every so often? I never knew that... i mean i knew to do that after every mod so the computer can adjust itself to the new intake/exhaust for instance. If thats the case i cant wait to get my Lude registered and on the road so i can reset it... im getting my CAI next week sometime... cant wait.

 

My boyfriend resets his ECU after every new performance part. And then after a long night of racing, or if someone else drives his car, basicly after a time when his car has been driven differently. It helps to have the car reset so it can change to your driving style.

 

though it takes a while for an ECU to become functionally efficient again. It's not practical to do it too often, after every mod is a good rule of thumb.

Plus after a reset if you want to run strong you have to drive HARD so that the ECU will set itself aggressively. that's too much gas $$$ for me to be running vtec in every gear

 

Nope, we didn't reset it. Just took it off and tried to see if there is any better performance, but guess not.

 

well, not sure if there would be, depending on where the air would be coming from (cold air or hot engine bay air) but assuming that the air it was drawing was cool enough, there would be an improvement in performance, but you wouldn't be able to tell unless you reset the ECU. it would be using old settings that would account for the old intake circumstances, and would not adjust A/F among other things accordingly.

 

yes, the bottom and top end and completely built, instead of listing mods ill just make it basic 300+ hp, 10k rpm, its heavily modded

 

my brothers 5th gen prelude ran 14.9 with just an intake, he is runnig low 13's high 14's with intake header exhaust, and a lot of other stuff.

 

What kinda intake? Stick? How about a 4th gen?

 

man. looking at your sig, it must have cost alot of money to hit 300...to the wheels or the flywheel?

bah i'm just looking to put 200-220 to the wheels, eventually. but i'd like to have the tightest suspension setup in the prelude world. Tein, how about a sponsorship?

 

my filter element fell off my short ram pipe and got lodged next to the battery one night. i think the kickback (FI backfire if u will) from a rev limiting shift blew it off the end of the tube. it probably wasnt tightened enough.
anyway
i was racing my friend, and we went one run and then the second run my engine started to revlimit at 6500 instead of 7800
so imediately killed the engine and pulled over on the3 highway and got out to check everything, and sure enough the filter was not on the pipe.

i guess it was revlimiting because it was retarding the timing based on sensing a lean condition because of 0 restriction on the intake charge.
(phew that was a run-on)
