lul wut?

VTEC is at 5800 unless you got a Hondata reflash.

Blackknight103 · 04-22-2009, 01:18 AM

New Vtec fluidzz?

FG-JOE · 04-22-2009, 01:20 AM

lose or let loose your power at 5800?

did you buy your car used?

Sle · 04-22-2009, 01:22 AM

double post ftl.

bmwst9 · 04-22-2009, 01:23 AM

yeah i do have the reflash

bmwst9 · 04-22-2009, 01:24 AM

no it looses power around 5k

bmwst9 · 04-22-2009, 01:24 AM

and yea i bought it used two years ago with 3k miles on it

Blackknight103 · 04-22-2009, 01:26 AM

you reflash went bye bye it sounds like.

bmwst9 · 04-22-2009, 01:30 AM

a reflash cant just disappear..its encoded into the ecu..its literally burned in it

FG-JOE · 04-22-2009, 01:31 AM

modS?

bmwst9 · 04-22-2009, 01:33 AM

intake , header , exhaust, tbs, hondata heatshield gasket, and the actual reflash

FG-JOE · 04-22-2009, 01:33 AM

no codes?

bmwst9 · 04-22-2009, 01:36 AM

nope...i wish there was so i have a general idea of wat it could be ..but no codes

B MAN · 04-22-2009, 01:39 AM

limp mode?

ussaully happens with FI though

FG-JOE · 04-22-2009, 01:41 AM

try MAF sensor?

B MAN · 04-22-2009, 01:43 AM

call hondata they'll probably have u send ur ECU back, thats probably your most painless solution right now... ur not shooting a CEL which i think means the car doesnt even realize something is wrong, and ur sensors are working correctly... however i think if ur ECU is bad it might not throw a code atcha...

Id get Hondata on the line try n get them to take a look at it, see wut they say and take it from there

bmwst9 · 04-22-2009, 01:44 AM

people have been tellin me maybe a the vtec solenoid maybe clogged or something like that?

i seriously have no idea..especially with honda's..i still dont understand these cars yet 100%..this is my first one so i dont no whats a common problem with them

bmwst9 · 04-22-2009, 01:45 AM

i called hondata and they told me there is absolutely no possible way for the reflash to actually go bad...they were pretty short in explaining it to me

FG-JOE · 04-22-2009, 01:48 AM

at this time of day? 24hr support?
