hey guys im a new EP3 owner and my question is can i put a stock RSX ecu in a stock ep3 . Also would it pop vtec or would i need Kpro....

 

no you cant, you already have vtec...kpro is an EMS that allows you to tune the car with modifications

 

So theres no way the ep3 can pop vtec at 5rpm ... What if i buy a different head would it work then with an RSX ecu or kpro would be my only opposition ... All i want is for the car to run like a K suppose to....

 

u also said that my car has vtec well i read more about it and it pops vtec at 2200rpm ( or opens its first chamber ) and around 5rpm it opens the next chamber ... Unlike RSX there vtec pops at 5800rpm and it opens both chambers at the same time .... N THATS WHAT I WANT TO DO TO THE EP3 ...I just need to know if i buy kpro could i tune it and make it pop vtec at 5800rpm...

 

NOOOOOOOOOOOOOOOOOOOOOOOOOO

First of you can't just swap an RSX ecu and think that everything is going to work!!!! The RSX ecu was tune for the A2 not the A3. Also the A3 and A2 are completely different engines... the A2 has 3 rockers instead of 2 and vtec is on the intake and the exhaust side unlike the A3 which is on the intake only!

Your K runs like a K should it's just not the way you want it to! Even with KPRO you won't have the crossover effect cause the engine wasn't designed to do that! So what you are looking at is swapping your engine for an A2 if you want that crossover... Also you will need an RSX ecu which will have to be flashed for your key to work.

KPRO is to tune your car to get more power and not add a vtec crossover!

 

you need to do research s0n.

the rsx type-s has 3 lobe vtec where as the ep3 motor only has 2 lobe, to achieve the goal you want, you have to do what dave said, swap the motor and get kpro...with kpro you can set the vtec engagement point...please do not say "pop vtec" sounds like a ratarded person.

essentially you could swap heads, camshafts, cam gears, timing chains, get krpo, etc... but by that point you might as well just have bought an a2, z1, z3 and swapped it in, keep in mind you can still use your ep3 transmission, the bottom end on the ep3 won't support the power with future mods if you plan on having 250+whp.

on a side note, did you seriously buy an ep3 with the expectation of hearing vtec engage louder? lmao...dumbest thing i have ever heard if this was your plan

 

look im sorry that im not talking like a professional an i said pop vtec .. i mean i was just askin a question u didnt have to be such an ******* about it and i also dont know nothing about EP3 when i bought it .. my other question is if i buy kpro and tune my car what kind off whp would i get with the a3 ..also if i stay with that a3 and buy cams rod ect.. would i get a lot off whp with it being all motor .. or would it just be a waist of time to do that to an a3..

 

Quoting Spaz on this one... best answer I have seen on HT!

 

searchhhhhhhh..

waste of time....save money, get krpo, swap motor, then other mods!
