I just researched a little about chipping ecu, but i have questions; is the uberdata, crome just more simple ems because they dont have any other addition circuit boards or hardware inside? I believe the circuit board for hondata s100 is only for the nitrous option and the a/c cutout option? So basically am i just paying extra for those two options if i get the s100 or s200?

For examble if I use this kit from here: http://<a href="http://www.moates.ne...html</a><br />
Is this pretty much a universal kit, The only thing the makes the tunning different I guess would be which program is used to tune the car with, but if a chip was tune on a either crome, uberdate, hondata can be used on this universal kit? I would have that 4 pin header for datalogging that is require for using Hondata is that correct?

Will i be able to return back to stock map easily, for smog purpose? I've heard a switch can be installed? or can i take off the jumper?

And will my knock sensor function correctly still?

I'm running jdm itr pistons with gsr block and head so I might get detonation. I would get a p28 and get that chipped but, I still want to retain my knocksensor on my p72 because it gets really hot where i live in the summer its around 100+ degress so I can be safe side. Or will it even help at all? I've seen some tuners disable the ks, after ecu chipping but why?


thanks

Well, I can tell you after doing a good night's reasearch (5+ hours reading about crome and uberdata + previous knowledge of hondata and talking to friends who are tuners) that the closest thing to uberdata/crome from hondata is the s300 because you can tune it yourself. As far as I can tell, with hondata you're paying for the name and stability, not to say that crome or uberdata aren't stable, just saying that hondata guarantees it.

I can't say much about datalogging with hondata but I'd guess you'd go about it the same way with those 4 pins. And as for the knock sensor, I don't know on any of your questions but I've read the same thing about tuners disabling the knock sensor.

FYI, I'm pretty sure the factory knock sensor is useless over 4000 rpms. After that it can't tell the difference between engine noise and detonation.
