are the new civics harder to tune since there are more electronic involved in them? when i went to the dealer the guy told me that the car is mostly controlled by computer. so i was just wondering is it alot of work to tune the car since so much of it is controlled by computer?

 

Right now, its impossible to tune the car because no one has figured out how, or at least figured out a reliable way to do it. You can change a few things with the Si reflash from hondata, but there is no way to "tune" right now.

 

but i have seen alot of people tuned them. is it risky?

In general, yes they will be harder to tune, at least once K-Pro comes out for the new Si. Unlike the the old B16's and B18's the new K motors allow you to change the cam phasing allowing you to change valve overlap and angle on the fly based on engine RPM, throttle position, etc. Also they run a mixture of MAF and MAP readings to set tuning maps, which is unlike the old speed density systems found in the B series.

This basically opens a whole new world to tuners seeking to squeeze every ounce of power out ofthe K20, and opens an insane amount of potential for the turbo aftermarket in terms of engine reliability and powerband. Hondata covers a lot about the new K motor tuning on their website (Hondata.com) that should help you get a feel on how much insane tuning potential the K motors have.

A reflash doesnt count.

 

the greddy e-manage ultimate works good

 

if you wanted to tune your car u shoulda got a RSX S

Not entirely true. The Greddy pnp 'tuning' device for their turbo kit offers a mild tuning solution. THe only problem with it, as far as I understand, is that it doesn't let you do a real 'in depth' tune and it constantly fights with the ECU for control.

i didnt have any problems with the stock ecu "fighting" the changes made via the emanage-ultimate. all changes i made resulted in very predictable changes in the way the engine ran on the dyno and on the street. the only downside is that for total control you would also need the V-manage to control the VTC, which as far as i know hasnt been tested on the 06 si.

 

Currently, the only option we really have is reflashes, which means we are really restricted at the moment. Greddy has something out, but I don't think it is nearly as flexable as KPro, and pretty much limited to 9 PSI of boost.

AJC has done a ton of stuff on tuning with Hondata, but I don't know if it is an stand alone system or reflash based.

Hondata is currently working on cracking the MAF/MAP sensors. Last I heard they were getting close. It will be interesting to see what Hondata has to say at SEMA this year.

For now it's "wait and see" mode for most of us.

the greddy pressure sensor is 3 bar... and the e-manage does hae map/maf clamping features

its still a piggy back, which sucks, but it works and there isnt anything else avalible right now
