I am thinking about doing this swap, but I am debating wheter or not to get a D17a2 ECU or just a VAFC2...

Some think that the ECU is better on the long run, other not since it's a VTEC-E... I am curious to see if one option is better then the other.

People with the swap could you please post your set-up and for how long you are you running without problem? Did you have problems with the swap?

The DIY exist since 2 years, we should be able to gather some reliability info on this swap!

Its about as simple as apple pie.....

The head swap IMO is as good with a Vfac... changing to a D17a2 computer will result in a tow to the garage for the ignition issue

save yourself the headache and get a vafc and get it tuned.

vafc-2 is the better way to go. so, like viper said, you dont have to reflash your ecu.

just take the ecu loose (leaving it connected), drive it to honda, have them reflash the EX ecu, then swap ecu's in their parking lot, and let it hang til u get home.

The ex ecu is better because it is made for the car. Theres nothing more reliable than stock. People can easily goof up and change settings they know not to change.

yeah...but thats alot of money for nothing. It will run the exact same on the LX ecu with the vtec controller, and its cheaper and no need to reflash.

yep, vafc2, you will have issues with abs, O2 sensors, and all the other stuff that we dont have.

Wow, who are you getting ur a2 head from? the person sounds pretty cool!

it is far less beneficial to use the factory ecu since it's programmed for fuel economy verses maximizing power output. you'll see more power output by using a VAFC-2 and spend less money doing it.

i use an emanage so the fuel conserving part is still there. (not a damn gas hog thank god)

And i have no problem with my abs or anything. Just my 2nd O2 sensor wire

Thanks for all the answers! I guess I'll go with the VAFC.

Anyone is running this swap presently? no engine problem yet?

<--- havent had a single problem with it

Cool!

You are using the a2 ECU as I understand. For how many miles are you running the swap?

BTW, welcome to the site!

 

wait, so all i need for a A2 swap (from lx) is the actaul head and a vafc-2 from apexi and im done??

yepp! do you need one?! LOL

pm me if you need one!

i think everyones pretty much said what i was going to say.. i ran with the head swap (since im the one that made the DIY.. lol) and havent had any problems.. i ran it all motor, and turboed and head was running strong.. now its just sitting in the storage

Ditto, first was n/a + a custom grind cam & emanage.. second was boosted with same setup. Not one hickup at all. You won't realize the full potential until you get it tuned.

 

so if i do the swap i should get it port and polished and then wat camshaft..stage 1 or n/a? I want to keep it all motor and will then get vafc2. Also would consider getting a new intake manifold and throttle body if the swap goes well. What do u guys think?

ive been running the mini-me swap for a little over a year now. Havent had a single problem with it

Only problem i had was actually from the emanage trying to control the vtec. All i had to do was wire the vtec back to stock

And thank you for the welcome

I will post some pictures of my car here shortly. I have been enjoying driving it the past few days because it was down for soo long

I may take some pics tomorrow.
