I have a civic si 2001 and I'am looking for an engine software to
communicate with the obd to change parameters

don't believe you can do it through the port. when you read about
people "chipping" their car, it's because they've had to disassemble
their ecu to replace/reprogram the [e]prom that stores the operation
map. the 2001 may be different, but i doubt it because no sensible
manufacturer would allow anyone to so easily create bogus warranty
claims resulting from inept remapping.

there have been a number of threads on slashdot about ecu reprogramming
over the years & the consensus seems to be that the manufacturers
generally know what they're doing regarding performance. annoying stuff
like speed limiting aside. rev limits should not be raised without
appropriate mechanical work to ensure sufficient mechanical strength,
balance, etc.

if you want a reprogramming project, check out

even v2 is not as sophisticated as the honda ecu, but it allows
experimentation if that's your desire. personally, if i wanted to mess
with this stuff, i'd do it on something /much/ cheaper than a 2001 si.

from what I've read on Hondata's site,they alter the ECU to accept user
programming,and provide a port to a PC for it.(VOIDING any warranty)
IIRC,the OBD sensors can actually be used to monitor engine performance and
record the data after a run,kind of like an on-board dyno setup.

Hondata.com and I have no connection in any form to the company .

wow, their prices are spectacular. as in, /way/ high.

and i'm not sure about their mechanical engineering either:

http://hondata.com/featuresrpm.html

says honda ecus are mapped to 9k??? revs are usually limited to
absolute max of 7k, 8k for the hot dual cams.

something does not compute.

That seems odd to me too - do the VTECs hit 9K? But then I don't understand
why people go to such lengths to enable their cars to go faster when every
experienced driver can remember at least one time when they wished with all
their hearts they were going slower. A strange mania indeed.

Tks guy !

I think that over 7k the valves are flotting and we loose power at that
point.

I notice that the civic si vtec 2001 has a carb instead of injectors , my
1998 had injectors is it a technical regression ?

which is one reason why we can't just adjust the rev limiter. need to
address valve train, cam, timing, balance, & strength of moving parts
before high revs "work".

really? you got a link for that? i see no online parts list showing a
carb for that model, or indeed any 2001 si in the u.s.

i think the exotics & the s2000 do, but none of the "normal" hondas do.
a /lot/ of work goes into getting honda reliability at those revs.

Some regions of the world have emissions laws that are sufficiently light
that carburetors are still viable. It is possible the car in question is
one of those.

The only reason we have ubiquitous fuel injection here is because federal
emissions limits are far, far too low for even electronically-controlled
carburetors to be able to meet.
