what does a tuned ecu do? Does it add horsepower?

If done right yes......Search.

that would depend on if you need it tuned, which would depend on what modifications you have done to your car, I mean even if you don't need it tuned it still may add hp but it probly won't be the cheapest way to add horse power... that is based on my small amount of knowledge on the subject

a chipped ecu will do nothing but may harm or may help a little unless it was properly tuned to your whole vehicle with the modifications you have done to the motor.

i have dc sports header, aem intake, tanabe exhaust, skunk 2 cams on a b20 vtec. my vtec kicks late at 6000 rpm. i just never got it tuned yet. maybe it be best to tune it?

raidacaipo

definetly needs a tune. stock b20 bottom block? at least arp rod bolts?

you definately need to get a tune done with those kind of mods. your A/F ratios have to be so far out that VTEC hits like a girl. what basemap did you use? i am assuming B16 since vtec is set for 6k?

GET A TUNE!!! when you mod things like air/ fuel ratio. you also mess withe the effectiveness of v-tec. if you want your car to be putting out the maximum power with all of your parts working as one then get it tuned! like that guy said your vtec prolly hits like a girl.

[QUOTE=dannyb2134;37150863]the only reason i know this who vtec hitting like a girl is because i did a built gsr swap with a b16 head and gsr cams on an ecu tuned for a stock jdm b16 and vtec was not impressive at all. once i go it tuned it screamed

[QUOTE=93egSLEEPER;37150892]right now its hitting like a gurl but once you get it tuned it will SCREEEEEAM like a gurl :]

ok looks like i gotta get it tuned asap.. ****, i been driving around with these mods for at least a year. i knew my car had more potential. So do i have to get it dynotuned or can i get a local shop to tune it without a dyno?

duyfash0

and what would happen if i go without the arp rod bolts? im not even sure if i got that done when i did. and was i doing any damage to my car while driving with it untuned?

You definitely want to have it dyno-tuned. street tunes suck in comparison

joelmatt89

Does anyone know what a dyno tune should cost... I am lookin for a ball park range

Anywhere from $100 to $200 an hour.
