Hey guys, I installed my test pipes and intake and I got slower. This is really weird, i'm wondering how long it takes for the ECU to actually recognize mods if it ever does. I'm sure I dont need a tune just for test pipes and an intake do I? Any information would help, thanks.

 

you should've kept your supra TT

 

leave the battery unhooked for the night, see if it resets the computer

 

Welcome to the wonderful world or Nissan ECUs

 

That's possible. What kind of test pipes and intake?

 

I reset the ecu for 30 mins when I installed the intake. I have megan test pipes and K&N air charger intake.

 

Define "slower" please.

0-60 times; ¼mile times; top speed. What are you basing "slower" on?

 

My rpm climbs slow, and compared to my buddies mustang which I was quicker than when I was stock, i'm slower compared to now.

 

Well, you could always try putting the stock parts back on and see if it returns to the previous level of performance. Especially the intake, the Z's stock intake is pretty good. There's not a lot of HP gain from a CAI, in fact some people claim you lose HP.

 

Well when i installed my test pipes i lost a bunch of torque and my car felt slower as well but made up for it up top.

 

It moved the power to a different end of the spectrum. Otherwise a rat crawled in your throttle body and died.

 

I've heard when you disconnect the (-) battery cable it takes 24 hours for the ECU to reset. Or you can try this: https://my350z.com/forum/showthre...=THROTTLE+BODY

 

Itll feel slower under 2500rpm, after that it'll feel alot slower. If ur doing intake exhaust mods the best thing u cna get is some kind of engine management.. jermaine made 28whp just off of test pipes and utec... he hit 300whp w headers, intake, exhaust, test pipes..manifold

 

I guess I now need a greddy e-manage ultimate.

 

needs atleast a day to clear.

btw, hopefully your megan pipes don't fall off in a week or two...

 

isn't that the guy who claimed it but never posted a dyno sheet?

 

After I did headers and such to my revup motor, it took awhile for the computer to adjust. After that I could definately feel the added power.

 

I hate these pos **** test pipes as well, i'm waiting until helix has the test pipes in stock they are on back order...

 

I hope so because its been 3 days since I installed the intake.

 

I have the helix test pipes and they work great... Go with a unichip or utec and you will definitely feel gains!
