i just got me lil hatch with a stock d16y8 i just put a p72 ecu in it. where would be a good shift point with out hurting anything? thanks

 

shift at the same rpm as you did before the ecu. you're not going to gain any power anyway.

 

Yup, same RPM as you did with your d16y8 before the ECU switch.

 

well i went from a p208 with no vtec to a p72 in a 93 car.

 

wtf is a p208? if you meant P28 yes they do have vtak

 

a p208 is the stock ecu for 92-95 sedan civic! it does not have have vtec. i noticed a big difference with p72 but the rev limit on a p208 is 6500rpm and the p72 is 8900rpm. i dont want to take the engine to high.

in America? No it isn't. The DX/LX sedan had a P06 and the EX sedan had a P28

don't believe me? https://honda-tech.com/zerothread?id=810101

 

so is the p72 is chipped for your car setup?

 

I wouldn't take it over 7200. There is definately no such ECU as p208

Rev until the RPM limiter hits. D16Y8's are good to like 12,000 RPM...especially with their great oil pumps and valvetrain

 

turbo it, then rev it up!

 

Where does it redline. There you go.

o make sure you take out all of your oil before doing so...that way your car can be lighter...

and dont forget to stay in first and second gears, helps your gas mileage as well as makes your top speed higher

Word man. I can rev my motorcycle to 11k, but you would totally be showing me what the deal is by revving to 12k!

Put your stock ECU back in. You're not helping yourself by putting in an ECU with the wrong fuel/timing maps.

 

Ok thanks to everyone who answered my question, but i didnt ask for a bunch of SMART *** ANSWERS. i put that p72 in my car, it runs a hell of alot better, but im still shifting a 6400. i just wanted to know what i can shift at safely. the was is a p06. not a p208.

Some of the "smarter" car guys came in here to tell you that it was a bad idea.

thanks for the staight answer, nevermind about the ecu's talk where can u shift a stock d16y8 safely regardless of tunes ecu' s or what ever.

 

7200

 

You dont know how much i thank you for that answer. it took me al most 20 post to get it. everyone tells me what i allready know or dont want to know. nbut anyways thanks again.

 

if you dont have vtec you dont need a vtec ecu. put your p06 back in. your only hurting your gas mileage.

 

The redline on that motor is 7200 RPM's, wouldn't take it that far though with the stock tach as they seem to be inaccurate, so shift at 7-7.2 and u'll be fine

 

have a better shift at 6800. its a Y8. less power at 72 then 6800. try it youll see. but your using a p72 ecu???? why??

 

oh yeah, that reminds me

If you can get ur hands ona stock P28 ODBII ECU go for it

It's made for that motor, it willl run nicely, 7200/7500 governor and some **** around 5800 vtec stock..it will run ur motor better than a P72
